Wisper 905 Torque crossbar
The latest addition to the Wisper range the 905 Torque needs to be tried before you buy anything else.
Wisper Torque bikes benefit from a new, powerful, almost silent motor controlled by the latest and most innovative torque/speed sensor on the market. The new system will give you instant access to masses of hill climbing power from the moment you start to ride. Simply push down on the pedal and the bike will reward you with a silent surge of power, the harder you push down on the pedals the more the motor will assist. When the bike reaches cruising speed, power will gradually ease back and when power is not needed at all, such as when descending hills, it will cut off completely giving you up to 40% extra range when compared to more basic speed sensor bikes. A torque sensor bike gives you instant access to power, a speed/cadence sensor only works after you have turned the pedals about half a rotation. A good torque sensor will provide instant power, longer range and a much more natural riding experience.
