Description

A Bead-Based Compression Drive System for Bicycles

[0001] The present invention relates to bicycles. Particularly, the present invention relates to a smart compression bead-based drive system that replaces the tensile chain drive most commonly used in the world today. This compression technology removes the need for regular maintenance and also reduces the risk of drive failure associated with chains, thereby providing a smoother and more reliable riding experience across diverse terrains and in all weather conditions.Background of the Invention

[0002] Cycling is widely recognized for its numerous benefits, encompassing eco-friendly transportation, promoting physical fitness, and contributing to overall well-being. As urban areas grow and environmental concerns rise, more individuals turn to bicycles as a sustainable alternative to motor vehicles. Bicycles offer an efficient means of commuting, helping to reduce traffic congestion and lower carbon emissions. Additionally, cycling serves as an excellent form of exercise, improving cardiovascular health and fostering a sense of community among cyclists.

[0003] Despite these advantages, traditional bicycle designs come with certain limitations that hinder their overall efficiency, safety, and usability. Most bicycles rely on chain-based drive systems to transfer power from the pedals to the rear wheels. While chain drives are effective in their functionality, this reduces within 2 weeks from new and chains require regular maintenance to ensure optimal performance. Over time, chains stretch, wear out, or suffer corrosion, leading to decreased efficiency and potential breakdowns. Moreover, these tensile systems are prone to slipping or breaking under pressure, especially during intense riding conditions or uphill climbs.

[0004] The exposed nature of chains and gears makes them particularly vulnerable to environmental factors such as dirt, moisture, and debris, which can lead to rust and performance degradation. These issues significantly increase maintenance demands, posing reliability challenges for riders who depend on bicycles for daily commuting or recreational use. In addition to the challenges associated with drive systems, traditional braking mechanisms mostly rely on wheel rim brakes using brake shoes and callipers but more expensive and professional bikes may have the luxury of disc brakes. While these systems can be effective, they sometimes result in abrupt stops, posing risks to rider safety and causing them to be thrown over the handlebars and into the path ofother vehicles but most callipers, brake shoes, and brake pads are poorly maintained and lead to poor braking and skidding.

[0005] This concern is particularly relevant in urban environments, wherein cyclists frequently navigate busy streets and encounter unexpected obstacles. Furthermore, for commuter cyclists, issues related to theft and availability of storage and parking to the problems encountered in everyday use of bicycles. Most traditional bike designs offer limited security options beyond basic locks, leaving bicycles vulnerable to theft when left unattended.

[0006] Recognizing these challenges, engineers and designers actively explore alternative drive systems that aim to improve the reliability, safety, and performance of bicycles. Recent advances in smart materials and intelligent mechanical designs pave the way for the emergence of chainless bicycles in an attempt to replace the tensile drive and the conventional chain and gear assemblies in use today. These new and innovative designs not only enhance the overall functionality of bicycles but also simplify them and their operation and maintenance.

[0007] The chainless bicycle drives both front and rear wheels simultaneously. It features a central pedal gear linked to a rear wheel gear, a front wheel gear, and dual drive shafts connecting the wheels. When pedalling, the central gear rotates, engaging both driveshafts, which then activate both wheel gears to propel the bicycle. This design ensures balanced power transmission to both wheels, enhancing stability and steering. By applying force to the front and rear wheels concurrently, the bicycle achieves a stronger forward motion, offering greater efficiency and performance compared to all traditional rear wheel tensile chain drive models.

[0008] Therefore, there is a need for a bead-based compression drive system to replace the traditional tensile chain mechanism and its overall maintenance needs. There is also a market for a bead-based compression drive system that comprises a removable cassette housing the rear wheel drive when the bicycle is parked and so reducing theft risks as the drive means would no longer on the bicycle.

[0009] There is also a great benefit in a theft-detection sensor which the bead-based compression drive system incorporates as an implant being embedded into one or more beads in the drive train and which will trigger an alarm if the bicycle is lifted off the ground at a height over 100 mm using a gravity sensor that sounds a signal and sendsto the owner’s fob style remote device which will be tuned in to the sensor frequency in situations where the drive cassette has not already been removed by the owner before parking the bicycle.

[0010] Further, there is also a real benefit for a smart bead compression drive gear box which is housed and enclosed within the pedal assembly and so protects it from external factors such as dirt and moisture, ensuring smooth and reliable gear shifting even in challenging conditions.Summary of the Invention[Oi l] According to an aspect of the invention, there is provided a bead-based compression drive system that replaces the traditional tensile chain mechanism and eliminates the need for constant tensioning maintenance caused by the gradual stretching of chain links, which reduces power transmission efficiency.

[0044] Figure 1A illustrates a side view of a bicycle 10 with a bead-based compression drive system 100. Figure IB illustrates an isometric view of the bead-based compression drive system 100 for bicycles. In one embodiment herein, the bead-based compression drive system 100 can be easily affixed to a frame of the bicycle 10 by a rider. The beadbased compression drive system 100 is configured to transmit rotational motion to both front and rear wheels (104 and 105) when the rider begins pedalling. The bead-based compression drive system 100 serves as a replacement for the traditional chainmechanism, thereby reducing maintenance requirements and enhancing overall durability.

[0045] In one embodiment herein, the bead-based compression drive system 100 comprises a drive unit 102. In another embodiment herein, the drive unit 102 could be connected to the frame of the bicycle 10 through a pair of pedals 106 of the bicycle 10. The drive unit 102 is configured to rotatably connect to the front wheel 104 and the rear wheel 105 of the bicycle 10. The drive unit 102 is configured to operatively connect to the front wheel 104 and the rear wheel 105.

[0046] In one embodiment, the bead-based compression drive system 100 comprises plurality of light sources 152 that is positioned on a front handlebar 14. The plurality of light sources 152, which may include multiple LEDs or similar illuminating components, is electrically connected to a battery that serves as a power source. This battery is capable of being recharged through the drive unit 102 of the bead -based compression drive system 100 when the bicycle 10 is in motion during a ride. The drive unit 102 harnesses kinetic energy from the first bead compression drive 112 and the second bead compression drive 116 of the bicycle 10 and generates electrical energy. This electrical energy is then used to charge the battery, thereby enabling it to continually supply power to the plurality of light sources 152 without needing external charging. The plurality of light sources 152 includes, but not limited to, LEDs designed to enhance visibility in low-light conditions, signalling to other riders or vehicles, and provide ambient lighting for aesthetic appeal. The placement and brightness of the plurality of light sources 152 are designed to ensure they are effective and visible from multiple angles, thus contributing to both safety and style in the overall design of the handlebar 14. In one embodiment herein, the front handlebar 14 could be a boomerang shaped handlebar.

[0047] In one embodiment, the bead-based compression drive system 100 comprises at least two actuation units 118, which are positioned on the front handlebar 14 of the bicycle 10 as depicted in Figure IB. The at least two actuation units 118 are configured for controlling the speed of the bicycle 10 effectively. The at least two actuation units 118 enables the rider to seamlessly transition between different speeds, enhancing the overall riding experience and providing greater control over the bicycle's acceleration and deceleration. The positioning of the at least two actuation units 118 on the fronthandlebar 14 ensures easy access for the rider, thereby allowing for quick and responsive adjustments without compromising comfort or safety.

[0048] Figure 2 illustrates a sectional view of the bead-based compression drive system 100 for the bicycle 10. In one embodiment herein, the drive unit 102 comprises a housing 108 (as shown in Figure 1A), a primary driven unit 110, a secondary driven unit 114, and the at least two actuation units 118 (as shown in Figure IB).

[0049] In one embodiment herein, the primary driven unit 110 is operably positioned through a U-shaped frame strut section 126 of the housing 108. The primary driven unit 110 is rotatably connected to the front wheel 104 via a first bead compression drive 112. The primary driven unit 110 is configured to transfer a rotary motion to the front wheel 104 when the rider rotates the pair of pedals 106.

[0050] In one embodiment herein, the primary driven unit 110 and the secondary driven unit 114 comprise a plurality of sprockets (132, 136, 134, and 138), which is configured to operatively secure the first bead compression drive 112 and the second bead compression drive 116, respectively. In one embodiment herein, the first bead compression drive 112 and the second bead compression drive 116 comprises a plurality of beads 144. The plurality of beads 144 could be at least one of marked beads and coloured beads. In one embodiment herein, the plurality of beads 144 are connected to each other to form like a continuous chain structure that is flexible and capable of transferring compression forces when driven by the pair of pedals 106. The interlocking design of the plurality of beads 144 allows for omnidirectional flexibility.

[0051] In one example embodiment herein, the plurality of beads 144 moves within the U- shaped frame strut section 126 of the bicycle’s frame. The U-shaped frame strut section 126 is designed to direct the plurality of beads 144 in a specific path while pedalling the at least one pedal 106. In particular, the U-shaped frame strut section 126 is positioned beneath the front handlebar 14. The U-shaped frame strut section 126 acts as a protective barrier to prevent dirt, dust, and other contaminants from entering a conduit system. The U-shaped frame strut section 126 could be at least one of a solid steel tube and a reinforced rubberised gasket.

[0052] In one example embodiment herein, the U-shaped frame strut section 126 helps reduce friction between the plurality of beads 144 and the surrounding components. The U- shaped frame strut section 126 ensures the plurality of beads 144 remains securely inplace, thereby preventing any dislocation or misalignment while they continually driving through the bead-based compression drive system 100. The plurality of beads 144 then moves into an uppermost conduit located on the left drive fork. This uppermost conduit is designed to guide the plurality of beads 144 towards the at least one sprocket 132 of the plurality of sprockets (132, 136, 134, and 138) associated with the front wheel 104. In one example embodiment herein, the U-shaped frame strut section 126 positioned at the underside of the front handlebar 14 and most likely connected via the left hand fork to the front wheel 104.

[0053] The left drive fork secures the uppermost conduit in place, ensuring the plurality of beads 144 moves down the conduit without obstruction. The at least one sprocket 132 of the plurality of sprockets (132, 136, 134, and 138) of the front wheel 104 rotates as the plurality of beads 144 push against it. This interaction creates the rotational motion to propel the front wheel 104 of the bicycle 10. After interacting the plurality of beads 144 with the at least one sprocket 132 of the plurality of sprockets (132, 136, 134, and 138), the plurality of beads 144 travel along an underside conduit, which completes a circuit by guiding the plurality of beads 144 back to their starting position.

[0054] In one embodiment hereon, the secondary driven unit 114 is rotatably connected to the rear wheel 105 via the second bead compression drive 116. The secondary driven unit 114 is configured to transfer the rotary motion to the rear wheel 105 with the rotation of the pedals 106. In one embodiment herein, at least two sprockets (132, 136) of the plurality of sprockets (132, 136, 134, and 138) are configured to secure the first bead compression drive 112 for driving the font wheel 104. In one embodiment herein, at least two sprockets (134, 138) of the plurality of sprockets (132, 136, 134, and 138) are configured to secure the second bead compression drive 116 for driving the rear wheel 105.

[0055] The at least one of the pedals 106 is connected to the at least one sprocket 134 of the plurality of sprockets (132, 136, 134, and 138) via a first crank arm 140, thereby enabling an independent movement of the rear wheel 105 while pedalling the at least one pedal 106, thereby allowing for synchronized energy transfer to the rear wheel 105. In addition, the at least one of the pedals 106 is connected to the at least sprocket 136 of the plurality of sprockets (132, 136, 134, and 138) via a second crank arm 140, thereby enabling an independent movement of the front wheel 104 while pedalling theat least one pedal 106, thereby allowing for synchronized energy transfer to the front wheel 104.

[0056] In one embodiment herein, the at least two actuation units 118 are operatively connected to the first bead compression drive 112 and the second bead compression drive 116, respectively. Each of the at least two actuation units 118 comprises the plurality of dampers 120.

[0057] In one embodiment herein, the plurality of dampers 120 is operatively connected to at least one of the first bead compression drive 112 and the second bead compression drive 116 via at least one brake lever 122, which is positioned on the front handlebar 14 of the bicycle 10. The plurality of dampers 120 is configured to apply controlled pressure to at least one of the first bead compression drive 112 and the second bead compression drive 116 upon activation of the at least one brake lever 122 by the user, thereby controlling the speed of the bicycle 10 by squeezing and regulating primary driven unit 110 and the secondary driven unit 114 to prevent sudden stops and minimize the risk of the rider being tossed over the front handlebar 14.

[0058] The plurality of dampers 120 is configured to operate just slightly ahead of the front wheel 104 so as to prevent the risk of the rider. The first and second bead compression drives (112, 116) are secured within the housing 108 to prevent external contaminants such as dirt, moisture, and debris and ensure a durable, low-maintenance design.

[0059] In one embodiment herein, each of the plurality of beads 144 of the first bead compression drive 112 is provided with a radio frequency identification (RFID) tag, which is adapted to communicate with a user device of the rider through a network, thereby enhancing security and preventing the bicycle 10 from theft. The plurality of beads 144 is predominantly manufactured from recycled materials, but not limited to, polyurethane plastic, which resists water absorption. Materials such as nylon, which may absorb water, are generally avoided to prevent the plurality of beads 144 from expanding and compromising the performance of the bead-based compression drive system 100. In one embodiment, the primary driven unit 110 is designed to transfer rotary motion from the pedals 106 to the front wheel 104 of the bicycle 10.

[0060] Additionally, the primary driven unit 110 is connected to the front wheel 104 through the first bead compression drive 112, which is embedded with the plurality of beads 144. The first bead compression drive 112 constraining an internal guide that housesthe plurality of beads 144 and allows smooth motion transmission, enabling the front wheel 104 to rotate as the user pedals. To ensure rider comfort, the primary driven unit 110 may also incorporate a dampening mechanism that minimizes shocks and vibrations during the operation. The plurality of beads 144 acts as compression drive elements, which are driven in line by the pair of pedals 106. In another embodiment, the secondary driven unit 114 is configured to transfer the rotary motion from the pair of pedals 106 to the rear wheel 105 of the bicycle 10.

[0061] The secondary driven unit 114 connects to the rear wheel 105 through the second bead compression drive 116, thereby enabling efficient propulsion. This setup allows the rear wheel 105 to operate independently while pedalling, which provides better traction control and improved handling in various riding conditions. Both the primary driven unit 110 and the secondary driven unit 114 operate in tandem, providing balanced propulsion to the bicycle 10. This coordinated action enhances control, allowing users to maintain stability, especially in challenging terrains. The dual-drive mechanism results in increased efficiency, as the bead compression drives facilitate effective energy transfer with minimal loss, leading to smoother acceleration and deceleration.

[0062] The drive unit 102 makes the bicycle 10 unrideable until it is securely reattached and reconnected to the plurality of sprockets (132, 136, 134, and 138) housed within the drive unit 102. To reinstall, the pedal crank is removed, and the drive unit 102 is clipped into place. Once positioned, the pedal crank and the pedals 106 are locked in to restore the system’s compression and operability.

[0063] In another embodiment herein, the first bead compression drive 112 of the drive unit 102 could be individually operated to create the motion for the front wheel 104 of the bicycle 10. In another embodiment herein, the second bead compression drive 116 of the drive unit 102 could be individually operated to create the motion for the rear wheel 105 of the bicycle 10. The bead-based compression drive system 100 provides flexibility in the operation of the bicycle 10, enabling the front wheel 104 and the rear wheel 105 to be driven independently when required, such as for specific riding conditions or maneuvers.

[0064] Figure 3 illustrates a block diagram of the bead-based compression drive system 100. In one embodiment herein, the drive unit 102 is connected to the bicycle’s framethrough the pair of pedals 106. The drive unit 102 includes a locking system 123, which is controlled by the control unit 128 for security purposes.

[0065] In one embodiment herein, the primary driven unit 110 transfers the rotary motion to the front wheel 104 via the first bead compression drive 112. The secondary driven unit 114 transfers the rotary motion to the rear wheel 105 via the second bead compression drive 116. The actuation units 118 control the bicycle’s speed by applying pressure on the first bead compression drive 112 and the second bead compression drive 116 using the plurality of dampers 120. In addition, the plurality of dampers 120 is connected to brake levers 122 on the front handlebar 14 for controlled braking.

[0066] The first bead compression drive 112 and the second bead compression drive 116 can be manufactured from recycled materials, which are resistant to water absorption for preventing degradation. The first bead compression drive 112 and the second bead compression drive 116 allow for interlocking with adjacent beads, forming the chain structure that can bend and rotate freely.

[0067] In one embodiment herein, the bead-based compression drive system 100 comprises at least one alerting unit 130 that is configured to notify the rider when the bicycle 10 is lifted beyond a threshold height (100-300 mm), thereby deterring theft. The control unit 128 is configured to receive signals from the at least one alerting unit 130 and send one or more alerts to the user to prevent theft. The control unit 128 receives the alerts and allows the secure code entry to lock and unlock the bead-based compression drive system 100.

[0068] In one embodiment herein, the locking system 123 is configured to enable the rider to enter a secure code to unlock a plurality of dampers 120 that locks the at least one of the first bead compression drive 112 and the second bead compression drive 116 when starts a ride. The secure code includes at least one of alpha numeric and colour codes.

[0069] In one embodiment herein, the bead-based compression drive system 100 comprises a sensing unit 124 that is positioned on the frame of the bicycle 10.

In one embodiment herein, the user device is at least one of a smartphone, a computer, a laptop, a tablet, a personal digital assistant (PDA), and thereof.

[0071] Figure 4A illustrates a front view of an individual bead within the plurality of beads 144. In one embodiment, the first bead compression drive 112 and the second bead compression drive 116 comprise the plurality of beads 144. In one embodiment herein, the plurality of beads 144 could be at least one of marked beads and coloured beads for easy identification. The plurality of beads 144 are structured into three main sections include two outer convex sections (145, 147) and a central section 146 positioned between them. The central section 146 has a slightly larger diameter than the convex sections (145, 147) to enhance stability within the drive system.

[0072] At one edge of the central section 146, there is a male extension 148, while the opposite edge features a corresponding female indent 147, allowing each of the bead 144 to interlock horizontally with adjacent beads, thus ensuring a secure and seamless connection across the entire bead-based compression drive system 100. The central section 146 also includes an aperture cut on its underside, specifically designed to accommodate the engagement of the gear teeth associated with the plurality of sprockets (132, 136, 134, and 138). This configuration enables the plurality of sprockets (132, 136, 134, and 138) to interact efficiently with the plurality of beads 144, thereby creating a continuous and reliable drive system.

[0073] Figure 4B illustrates a front view of the plurality of beads 144 interconnecting with each other. In one embodiment herein, each of the bead 144 is designed with the female indent 147 on one side and the male extension 148 on the opposite side. This interlocking structure allows each of the bead 144 to align with adjacent beads by fitting the male extension 148 of one bead into the female indent 147 of the next one. This configuration enables the plurality of beads 144 to form like a continuous chain structure that is flexible and capable of transferring compression forces when driven bythe pair of pedals 106. The interlocking design of the plurality of beads 144 allows for omnidirectional flexibility.

[0074] Unlike traditional chains, the plurality of beads 144 can twist and turn without being restricted to a single plane, providing flexibility in different directions while maintaining alignment. This feature is particularly beneficial for maintaining smooth propulsion across various terrains. Each of the plurality of beads 144 is equipped with a pair of restricting members 150 that prevent unwanted rotation while facilitating the forward movement of the bicycle 10. The plurality of beads 144 is able to compress and expand slightly, allowing the bead-based compression drive system 100 to accommodate minor variations in force and adjust to different riding conditions.

[0075] The interconnected structure of the plurality of beads 144, with the male-female locking system and flexible design, allows the bead-based compression drive system 100 to function effectively while providing unique security and safety features. The beadbased compression drive system 100 not only enhances propulsion and control but also serves as a modern alternative to traditional chain drives, offering advantages in durability, security, and ease of maintenance.

[0076] The interlocking structure enables the plurality of beads 144 to form a continuous, flexible compression driven by human foot pressure on the pedals 106, propelling the first bead compression drive 112 and the second bead compression drive 116 along the frame of the bicycle 10.

[0077] In one embodiment, the plurality of beads 144 could be one of disc-shaped elements and spherical beads. Alternatively, if the disc-shaped elements are used in place of spherical beads, they may feature a serrated surface similar to a cog. This serrated configuration allows the disc-shaped elements to engage within a designated channel or groove, pushing one another forward or backward through interlocking teeth, while maintaining a perpendicular alignment to the channel as they move.

[0078] The design of the discreet beads 144 ensures a male and female connection that maintains alignment while allowing for omnidirectional flexibility. Thus, the plurality of beads 144 can twist and turn without being restricted to a single plane, unlike a traditional chain. In one embodiment herein, the frame of the bicycle 10 will have a small window or an opening to enable the plurality of beads 144 to be viewed in order to detect wear and tear.

[0079] Figure 4C illustrates a front view of the plurality of beads 144 as they pass through the plurality of sprockets (132, 136, 134, and 138) having a gear teeth profile. In one embodiment herein, the plurality of beads 144 in the bead-based compression drive system 100 pass through the plurality of sprockets (132, 136, 134, and 138) to transfer the motion from the pair of pedals 106 to the rear wheel 105 and the front wheel 104 of the bicycle 10. The plurality of beads 144 is arranged to form the first bead compression drive 112 and the second bead compression drive 116, respectively.

[0080] When the rider pedals, the rotation of the pedals 106 drives the crank arms 140, which are connected to the plurality of sprockets (132, 136, 134, and 138). The rotation of the plurality of sprockets (132, 136, 134, and 138) causes the plurality of beads 144 to be driven, thereby operating the first bead compression drive 112 and the second bead compression drive 116. This motion transfers the rotational energy generated by pedalling into linear movement of the first bead compression drive 112 and the second bead compression drive 116, which is then converted back into rotational motion of the front wheel 104 and the rear wheel 105.

[0081] The interlocking design of the plurality of beads 144 allows them to maintain alignment and transmit compression forces without slipping. As each bead 144 pushes the next one in line, they collectively drive the plurality of sprockets (132, 136, 134, and 138), which are engaged with the front wheel 104 and the rear wheel 105, respectively. This setup provides a smooth and flexible transmission of force, unlike traditional chains that rely on tension and can be prone to stretching.

[0082] The plurality of beads 144 of the first bead compression drive 112 (connected to the primary driven unit 110) control the motion of the front wheel 104, while the plurality of beads 144 of the second bead compression drive 116 (connected to the secondary driven unit 114) drive the rear wheel 105. This dual-drive mechanism enables synchronized propulsion of both the front wheel 104 and the rear wheel 105, enhancing the bicycle’s stability and control.

[0083] The plurality of beads 144 is configured to work under compression rather than tension, which provides durability and minimizes the risk of breakage. Additionally, the plurality of beads 144 is locked into place via a secure code in the control unit 128, which disengages the plurality of dampers 120 and locks the drive system for security when the bicycle 10 is parked. As the plurality of beads 144 passes through the pluralityof sprockets (132, 136, 134, and 138), they maintain firm contact and alignment, which enables the effective transfer of pedalling energy to the front wheel 104 and the rear wheel 105.

[0084] The first and second bead compression drives (112, 116) allow the rider to input a unique alphanumeric code, which may also incorporate specific bead colours. This alphanumeric or colour code is linked to the handheld control unit 128 and remains known only to the rider. When the correct code is entered, it locks or unlocks the bead compression drive trains, engaging or releasing the plurality of dampers 120 as required to secure or free the bicycle 10.

[0085] The flexible but interlocked structure of the beads 144 reduces energy loss due to friction, leading to smoother acceleration and efficient propulsion. The plurality of beads 144, with their interlocking design, pass smoothly through the plurality of sprockets (132, 136, 134, and 138) by aligning with the sprocket grooves, thereby transferring pedalling force to the front wheel 104 and the rear wheel 105 with minimal energy loss. This innovative design provides a flexible and durable drive system for the bicycle 10, capable of adapting to different terrains and riding conditions.

[0086] Additionally, the alerting unit 130 is embedded in the front wheel drive and detect any lifting motion, such as an attempt to transport the bicycle in a vehicle. This front-drive operates as a separate system connected to the pedals 106, moving a second line of beads up the angled front frame.

[0087] The bead-based compression drive system 100 is designed to be extendable by a few millimetres, thereby allowing retrofitting to existing bicycles and providing a cost- effective alternative to traditional tensile chain drives, which are prone to stretching and breaking. The plurality of beads 144 can detect theft in multiple ways and may house an Al or intelligent location chip to assist in locating the bicycle 10 and its rider. This feature provides peace of mind for parents monitoring their children's whereabouts while cycling. Advanced tracking and traceability options can be integrated into the using Al and telemetry.

[0088] The plurality of beads 144 pass through a rubberized, concertina-style diaphragm, enter a left fork, travel down the left tube, thereby driving the at least one of the plurality of sprockets (132, 136) of the front wheel 104. This design introduces the world’s first two-wheel compression drive for bicycles, marking a milestone in cycling technology.From the wooden “boneshaker” to the Penny Farthing and the chain-driven bicycles of the 1900s, this innovation signifies a revolutionary step forward a two-wheel, compression-driven bicycle that embodies the next era of human-powered transportation.

[0089] One of the pedals 106 is connected to the at least one sprocket 134 of the plurality of sprockets (134, 138) through the first crank arm 140, which enables the rear wheel 105 to move independently when pedalling. Likewise, the other pedal 106 connects to the at least one sprocket 136 of the plurality of sprockets (132, 136) via the second crank arm 142, allowing for independent movement of the front wheel 104 during the pedalling. This dual-sprocket system provides enhanced control and traction by distributing power to both the front and rear wheels, maximizing stability and efficiency across varying terrains.

[0090] Figure 5A illustrates a sectional view of a removable cassette 500 detachably affixed to the rear wheel 105 of the bicycle 10.

[0091] Meanwhile, at least one cogwheel 162 of the plurality of cogwheels (160, 162) is an integral component of the secondary driven unit 114, enabling seamless, synchronized energy transfer to the rear wheel 105. The energy transfer from the rare wheel driven unit 508 to the rear wheel 105 occurs through a rare wheel bead compression drive, which ensures smooth and consistent propulsion. This setup allows the rear wheel 105 to engage independently with the pedal motion, allowing for efficient power distribution and enabling the rear wheel 105 to operate with enhanced traction control.

[0092] The independent operation also facilitates improved handling, especially in varied riding conditions such as off-road or uneven terrain, as it minimizes slippage and optimizes the rider's control over the bicycle 10. Consequently, this design enhances both performance and safety, providing the riders with a more stable and adaptable cycling experience.

[0093] In one embodiment herein, the removable cassette 500 is configured to detach from the rear wheel 105 for safekeeping when the bicycle 10 is parked through the locking system 123 (as shown in Figure 3) connected to the control unit 128 (as shown in Figure 3).
