Your first step is to decide on the frame style to suit your needs. The unisex 705 Lowstep and 905 Crossbar frames are incredibly versatile and work as a commuting bike or weekend explorer. The 705 comes in a 26″ wheel and for those wanting a smaller bike a 24” wheel option. If storage space is at a premium or you want use your Wisper for the “last mile” of your commute then the 806 folder is perfect, quickly folding to store away.
Now select which sensor system you would like. Our standard e-bikes use a market leading cadence sensor that measures the speed that the pedals are being turned, providing responsive application of power. Cadence sensors switch the power on when pedals are being turned forward and off when pedaling stops.
However for a smoother even more responsive application of the power, choose the Wisper Torque Power Pack option. Here the Cadence Sensor is upgraded to bottom bracket Torque Sensor, and the Standard Controller is upgraded to Sine Wave controller.
The advantage of this upgrade comes in more efficient power use, quieter and smoother motor function. More natural riding experience and immediate power delivery from the motor as soon as the pedals are pushed down.
The Torque Power Pack Innovative software cleverly combines information taken from the bike’s sensors to provide a seamless and natural riding experience. The benefit of the Wisper Torque Power Pack upgrade can be best experienced when setting off – especially on an incline. The moment you put pressure onto either pedal, the bike will react by gently engaging the motor. The more pressure you put onto the pedals, the more assistance you will receive from the motor.
Once the bike is underway the power assistance will gradually reduce until it’s needed again – such as when cycling up hills, entering strong head winds or if you need to accelerate. The efficiency of the Torque system increases the Wisper’s range by up to 30% when compared to the standard cadence sensor.
Despite its superb hill climbing ability, our torque drive system is virtually silent and is almost undetectable with the high torque motor sitting unobtrusively behind the rear gear cassette.
Now all you need to do is select the optimum battery size for your use of the bike.
