Stabilising inertia flywheels for bicycle - are on both sides of sprocket provided with balance weights for easier riding

摘要

The inertia system ensures easier driving of a bicycle. Correct weight distribution of the inertia flywheels ensures high stability on the road. On the crank arms of the pedal bearings are fitted two flywheels for balancing, having welded counterweights for developing high inertia force. This force is highly effective even at low speed. The balancing mechanism is made with hub plates riveted together and carrying the flywheel rim with spokes.
