// Brakes

A conversion kit adds power the bike's brakes were never specified for. A 2000W hub motor takes a 25 km/h bicycle to 55 km/h and puts roughly 15 kg of motor and battery on the frame, so the two-piston caliper that used to stop it is now being asked to handle nearly twice the speed and half again the weight. Brake fade on the first long descent is how most people find this out.Six pistons spread the clamping force across a longer pad. That means more bite for the same effort at the lever, and far more consistent stopping once the rotor is hot, which is exactly the condition a heavy high-speed build creates. Ours arrive pre-bled and ready to fit, so it is a bolt-on job rather than an afternoon bleeding lines on the garage floor.Fit them to the rear, where a hub-motor conversion carries most of its weight and all of its drive. Every F1 conversion kit already ships with brake cut-off levers that cut the motor the instant you pull either lever. This is the hardware those levers deserve to be pulling on.Not sure whether what is on your bike is up to it? Read why stock brakes fail on a conversion before you order.FREE AUSTRALIA-WIDE SHIPPING.
