The crank includes a crank arm and a crank spindle rotatably connected to the frame and non-rotatably connected to the crank arm.

The driven sprocket rotates to drive a driver, one side of which is coupled with the driven sprocket.

A central shaft (10) is a crank.

The carriage can be moved forward and backward via threaded extender rods which engage the pedal carriage to move it along the extender rods when they are rotated by a suitable drive means.

The pedal crankshaft or a bottom bracket is already integrated in the drive unit when the connection is made between the drive unit and the bicycle frame.

The left crank-gear is secured to the crank axle so as to obtain offset teeth with respect to the teeth of the right crank-gear.

Means are provided for transmitting pedaling actuation on the crank set to the rear wheel, the means being on the second side of the bottom bracket shell.

According to the invention, the user actuates the crankset (1) using the pedals (20).

The crankset is also noteworthy in that each crank takes a pedal which is fitted directly to the crank.

Crankset dte (with the current software) plug and cable specific to the vehicle guidelines support for the crankset.

In the passive mode, when no voltage is applied, the MR damper behaves like any ordinary damper.

Both the hand crank (50) and foot crank (60) may be detachable.

You feel it through the wheel, the seats, the pedals.

The semi-rigid bottom bracket according to the invention is intended specifically for use on a bicycle.

My current pedalboard does not include any effect.
