Wisper - 905 Torque 575wh

Technical Specification

The Wisper 905 Torque should be carefully considered before you buy anything else. Our superb Torque range of electric bikes has been developed by the team at Amps in Sevenoaks Kent to out-perform nearly all other ebikes on the market. Wisper Torque bikes are solidly built, nimble, almost silent, discrete, powerful, and very responsive. Astonishing value for money for the high specifications. In our opinion, a better, classier ride than any mid motor bike in its class. We would be delighted to arrange a test ride for you.

High efficiency, 250W ultra hi torque 50Nm brushless rear wheel drive. Hybrid Torque drive system designed to deliver maximum power to the rear wheel smoothly, quietly and efficiently.
