Embodiment Construction

[0022] figure 1 and 1a A bicycle 1 is shown with a frame, in which a seat tube 2 can be seen. At the bottom of the seat tube 2, a bottom bracket 3 is attached, which includes within it a crankshaft 6 which transmits torque from the rider via the front sprocket 4 and chain 5 to the rear wheel , see also figure 2 . The seat tube 2 is manufactured such that the seat tube 2 includes a larger diameter at the lower end than at the upper end. The diameter at the lower end is increased so that an electric motor 7 can be accommodated on the underside of the seat tube (see image 3 ). The seat tube 2 tapers upwards from the lower part in which the electric motor 7 is housed to the usual diameter of the seat tube of a bicycle frame. The battery-powered electric motor 7 , not shown further here, comprises a driven shaft 8 , which is connected to a coupling element 16 by means of a drive train. The coupling element 16 is rigidly connected to the front sprocket 4 . The drive train ...

Description

technical field [0001] The invention relates to a bicycle with an electric drive comprising: an electric motor with a driven shaft coupled to the front sprocket through a drive train; a battery and a controller connected to the An electric motor, the controller being arranged to control power supplied to the electric motor. Background technique [0002] More and more people use bicycles with electric drives. The electric drive is used to support the usual drive using the force exerted by the cyclist on the pedals. In many cases, the electric drive is housed in the hub of the rear or front wheels. However, this has the disadvantage that the available space is very limited, especially since the hub also accommodates gears and / or brakes. The bicycle hub usually also houses a dynamo. Another disadvantage of housing the drive in the hub of the front or rear wheels is the unbalanced or unfavorable distribution of the additional weight of the drive motor. Additionally, there i...
