The mechanical advantage of electric v brake bicycle is very high thanks to:
1. Direct pull. Electric v brake bicycle doesn’t have a transverse cable. The brake cable is directly pulling the brake arms.
2. Advantageous pulling angle. The pulling angle from which the cable on the electric v brake bicycle is very advantageous. In consequence, the rider can apply a lot of force onto the rim.
Since electric v brake bicycles don’t rely on the transverse cable found on cantilever brakes, both systems utilize different cable guide systems.
Electric v brake bicycles designed for cantilever brakes have two additional final cable hangers/cable stoppers – one above the fork and one over the seat stays.
Mechanical advantage - Electric v brake bicycles have a great mechanical advantage.
Electric v brake bicycles have a fixed, high mechanical advantage whereas the leverage of cantilever brakes can be increased or decreased by adjusting the length of the transverse cable and the angle from which it pulls.
