1 TARIFF BICYCLE THAT GENERATES ENERGY WITH A MAGNETICALLY RESISTANT BRAKING SYSTEM. TECHNICAL AREA 5 The invention has magnetic properties that can be used in the bicycle industry and micro-mobility systems. It relates to bicycles that provide resistive braking and kinetic energy recovery. PREVIOUS TECHNIQUE 10 Current braking systems used on bicycles are basically friction-based mechanical. It operates on these principles. Rim brakes, disc brakes (mechanical or hydraulic) and In common systems such as drum brakes, the braking process is carried out by brake pads or This occurs when the shoes press against the rotating surface. This method converts kinetic energy into 15. It converts this energy entirely into heat, causing the bicycle to slow down. However, this energy is not recovered. It cannot be recovered and is wasted. Furthermore, due to friction-based structures, brake pads... Parts like discs and rims wear out constantly, requiring frequent maintenance and part replacement. In rim brakes, rubber pads press against the rim surface. This system is inexpensive and costs 20 Despite their simplicity, shoes wear out quickly and need to be replaced frequently. Wet On these surfaces, braking performance decreases significantly, the rim surface wears down over time, and Maintenance costs increase. In mechanical disc brakes, the brake pads press against the steel disc. Although this system provides more powerful braking, regular adjustment and replacement of brake pads are necessary. It is needed. High heat is generated during braking, which leads to a loss of performance and 25 This can lead to disc warping. Hydraulic disc brakes are a more advanced technology. They offer; because they operate using oil pressure, they provide more precise braking. However They are structurally complex and costly, carry the risk of hydraulic leakage, and are long-lasting. Performance decreases due to overheating during landings. Bell or drum. In brakes, internally expanding shoes are used. This system has a more enclosed structure. 30 Despite offering good performance, it's heavy, heat builds up inside, and braking is poor. Also, water and... Mud accumulation negatively affects performance. 2 The common disadvantage of all these systems is the kinetic energy generated during braking. Energy recovery is the process where energy is completely lost by being converted into heat. It is not sustainable because it is not done that way. Due to friction-based structures, the parts It wears down constantly, requiring frequent maintenance and parts replacement. Excessive braking during prolonged periods. There is a risk of overheating and deformation. External factors such as mud, water, and dust affect brakes. 5 It reduces performance. Additionally, noise is generated due to friction, and the user... The experience is negatively affected. Current braking systems suffer from energy inefficiency, wear and tear, maintenance costs, and environmental issues. Many problems such as sensitivity to conditions and security risks 10 These problems necessitate a more sustainable, wear-free, and durable approach to cycling. It is clear that a new braking system that provides energy recovery is needed. It shows. Common braking systems used on bicycles include rim brakes and disc brakes. 15 (mechanical or hydraulic) and friction-based brakes such as drum / drum brakes These are mechanical brakes that rely on a rotating mechanism.

In current systems, braking energy is entirely 20 It is converted into heat and wasted; therefore, energy recovery is not possible. 1.

Disadvantages: 25  Because it is a friction-based system, brake pads wear out quickly and frequently. It requires frequent changes.  Braking performance is significantly reduced on wet surfaces.  The wheel surface wears down over time, increasing maintenance costs.  The energy is completely converted into heat; there is no recovery. 30 3 2. Mechanical Disc Brakes It operates using metal brake pads clamped onto a steel disc. Disadvantages:  Brake pads require regular adjustment and replacement.  High heat is generated during braking; this can lead to a loss of performance. 5  There is a risk of disc deformation.  Energy is wasted again. 3. Hydraulic Disc Brakes These are advanced braking systems that operate using oil pressure. 10 Disadvantages:  It is structurally complex and costly.  Hydraulic leaks and maintenance requirements are high.  Performance may decrease due to overheating during long descents.  It does not recover kinetic energy. 15 4. Drum Brakes It uses brake pads that expand from the inside. Disadvantages:  It is heavier than other braking systems. 20  Heat builds up inside and braking may weaken.  Water and mud accumulation affects performance.  There is no energy recovery. Key Common Disadvantages of Existing Systems 25  It is entirely friction-based, therefore the parts wear out constantly.  Kinetic energy is completely converted into heat and wasted.  Energy recovery is not possible; it is not sustainable.  Requires regular maintenance and parts replacement.  Noise may be generated due to friction. 30  They are sensitive to external factors such as mud, water, and dust. 4 The magnetic resistive brake + energy generation system, which is the subject of this invention, is described above.

As the rotor rotates, 15 It creates a changing magnetic field around the coil. It is made of stainless steel. Magnet housings are opened using CNC cutting and protected with epoxy coating. Braking It provides the necessary magnetic resistance effect and generates an induced current within the coil. Fixed Coil / Generator (2): 20 fixed to the fork or frame of the bicycle The coil / generator module is positioned right next to the rotor. As the rotor rotates... a variable magnetic field created by magnets causes an electric current in the coil It induces a coil wound from copper wire into a vibration-resistant polymer housing. It is positioned. Behind it are the rectifier circuit and the charging module. Braking During this process, the coil approaches the rotor magnets, creating an eddy current, and 25 It provides a braking effect. Spring Mechanism (3): Fine adjustment between brake lever and coil module It provides the mechanism. Thanks to a small spring or rail carrier platform, the coil The rotor approaches or moves away from the magnets. This movement increases the braking intensity to 30. It controls the process. For light braking, the coil moves to the middle range; for full braking, it moves to the middle range. 9 It is brought close to the rotor.

As a result, the rotor's rotational speed slows down. and braking is applied. Because there is no mechanical contact during this process, no wear occurs. During braking... The change in magnetic flux inside the coil becomes stronger, and more electricity is generated. energy is produced. The energy produced is stored in the Li-ion Energy Storage Unit (4). or stored in a Li-Po battery. The stored energy powers the bicycle lights, GPS.
