Problems solved by technology

[0061] In addition, Maderna Cycle Systems, Vienna, Austria, MCS16″ and MCS city series bicycles produced by Maderna company have the following disadvantages: the bicycle is only suitable for people with little difference in height, because the height of the steering tube connected to the fork bar cannot be adjusted
In principle there is a risk of slipping on soil and / or wet ground

Embodiment Construction

[0212] figure 1 Is a side view of a first preferred embodiment of a bicycle including a double sided rear suspension, head angle setting device and a bicycle drive with 6 speeds and a transmission unit with planetary gears on a 14 inch rear wheel , the bicycle is ridden by a person with a height of 2.0m.

[0213] The bicycle has a frame comprising a front frame part 1 , a rear frame part 2 and a folding hinge 3 . According to DE 10 2011 053 733 B4, the frame is produced from an extruded profile with three sections 1a, 1b, 1c and / or 2a, 2b, 2c, wherein the outer sections 2a and 2c are used as chainstays.

[0214] The ends 4 are inserted into the outer sections 1 a and 1 c of the front frame portion 1 to rotatably mount a head pipe 6 via a shaft 5 . The standpipe of the front crown 7 is supported on the head pipe 6 . Fork leg 8 is connected with front fork crown 7, is connected to the fork end 9 of fixed bicycle front wheel 10 again. Above the head tube 6 , the bicycle has a...

Abstract

The invention relates to a compact, foldable bike with small wheels and a bicycle drive for driving the rear wheel, comprising a traction mechanism or a spur-gear transmission, driven by a crank, the distance of the bottom-bracket axle to the rear-wheel axle being larger than half the outer diameter of the rear wheel. The bicycle exhibits a front frame part and a rear frame part that are rotatably connected to each other by a folding hinge that is aligned at right angles to the ground plane, whereby the front frame part, the rear frame part, and a front-wheel fork, in the folded state, seen laterally, form the sides of a triangle having the following characteristic combination of features: The bicycle is ridden while standing up, the driving wheel and the output wheel of the bicycle drive are arranged on the same side of the bicycle frame and the steering tube exhibits a lower and an upper steering tube, that in the folded state of the bicycle are folded-in laterally beside the front wheel. With this combination of features, a particularly compact folding size is achieved for the folding bicycle.

Description

technical field [0001] The invention relates to a compact folding bicycle according to the preamble of claim 1 . Background technique [0002] Combined with (electric) means of transport, such as trains, cars or airplanes, or combined with boats, folding bicycles or scooters are considered human or electric means of transport. [0003] These means of transportation are intended to reduce the time spent commuting distances. Further, folding bicycles can be used in situations where there is not enough room for a 26 / 28 inch bicycle while traveling. [0004] To achieve these goals, a vehicle suitable for adults must aim to achieve the smallest possible folded size, the lightest possible weight, and a comfortable riding experience. [0005] In this regard, the folding bicycles available on the existing market have the following disadvantages: [0006] a. They are relatively heavy (greater than 10kg), and lighter versions of the bike are expensive because they use more expensiv...
