Off-Road Kits

Off-road kits are our 2000W to 4000W rear hub systems on 52V, 60V and 72V batteries, built for mountain bikes ridden on private land, trails with permission and closed courses. They are not road legal in the UK or EU and are sold for off-road use only.

What to check: a 135 mm or 142 mm rear dropout on a steel or aluminium frame, hydraulic or strong mechanical disc brakes, a torque arm (included) fitted on the drive side, and tyres rated for the speed. Our brakes and wheels for high-power kits guide and the torque arm guide cover the upgrades most riders need.

Choosing power: the 52V 2000W vs 60V 3000W vs 72V 4000W comparison sets the three systems side by side, and the controller tuning guide explains how the Ride Power app sets assist levels and current limits.
