<p>#CMT# #/CMT# Device for activating an auxiliary motor of an electric bicycle has a chain wheel (20), a drive pulley (30), a multiplicity of activation pins (60) and limiting projections (23). To activate the motor switch an activation pulley (70) is withdrawn from the activation pins in an outwards direction. #CMT#USE : #/CMT# Activating device for an auxiliary electric motor for a bicycle. #CMT#ADVANTAGE : #/CMT# The invention ensures that the motor is reliably automatically started when the power applied via the pedals reaches a threshold value. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a perspective exploded view of an inventive device for activating the auxiliary motor of an electric bicycle. 20 : chain wheel 30 : drive pulley 60 : activation pins 23 : limiting projections 70 : activation pulley.</p> |
