FIELD: transport.

SUBSTANCE: invention relates to bicycles wherein pedal shaft passes through wheel hub to be coupled with wheel via universal joint or constant velocity joint. On turning handlebar 10 in the limits of preset angle, fork 4 may not turn. On turning handlebar through angle exceeding preset one, handle bar thrusts against ledges 16 of fork 4 to turn that latter and the wheel. Springs 15 are arranged between frame 13 and fork 4, spring mounting force being sufficient to retain fork 4 in neutral position and no inhibiting the turn of fork 4 after turning handlebar 10 into extreme positions thanks to forces applied to springs 15 exceeding preset force. On returning handlebar 10 in neutral position, fork 4 automatically holds its neutral position.

EFFECT: ruling out handlebar swinging from forces applied to pedals.
