FIELD: transportation.
SUBSTANCE: invention relates to the field of transport, in particular to the additional bicycle gears. Additional bicycle gear, which is integrated with the multifunctional quick-release luggage rack, contains the motor, the batteries and the fastening system, the geared drive wheel, the housing with the cover. Teeth of the drive wheel have a narrow and axially extended apex. Gear wheel is installed with the clearance in relation to the driven wheel and comes into contact when rotating using only one tooth into the deformable surface of the driven wheel. Each contact of the geared wheel with the driven wheel is successively replaced with the non-contact position. When the rotation of the motor stops, the geared wheel maintains the non-contact position and does not interfere with the free movement of the driven wheel.
EFFECT: improved drive reliability is achieved.
