More torque than any other

Whilst there are higher-powered hub drive units available, nothing beats the hill climbing, wheelie-popping direct power of the mid drive. To tame the torque this kit includes the patented ‘Gear Sensor’ from Agentura REPRO by default. With other BBS units this is optional however because of the high torque of the BBS-HD, this is mandatory otherwise your transmission will be toast after 1 ride. The Gear Sensor system is easy to install and momentarily inhibits the power from the motor for just long enough to gear shift. You will need to select from 2 options (derailleur or internally geared hub) when purchasing.
GearSensor is the undisputed authority on design and development of this device which solves a common issue that all mid-drive electric bike drive systems are prone to. Agentura Repro has developed a GearSensor for derailleur and internally geared transmissions (select which below) that senses shifting and sends a signal to the BBS drive that inhibits the power for the perfect amount of time required for a complete shift. The GearSensor works reliably on every shift so you don’t have to think about coming off the throttle or ‘blipping’ the e-brakes.
