The Wisper 705 from the UK is an unusual e-bike as it is that rare breed, an e-bike with a hub motor and torque sensor.
In case you don’t know, e-bikes tend to be split into two camps; those with a torque sensor that responds to pressure on the pedals and those with a pedal motion (cadence) sensor that, as the name suggests, simply respond to the movement of the pedal cranks.
E-bikes with torque sensors tend to ride in a more ‘bike like’ fashion as the power responds in proportion to the power applied to the pedals, whereas motion sensor bikes send the same amount of power to the motor (dependent of course on your power setting), regardless of the pressure applied to the pedals.
This means motion sensor bikes can feel less subtle to ride than a torque sensor equivalent, as well as being less economic with your precious battery power.
In fact, the Wisper 705 Torque has both types of sensor and you can opt to use whichever one you like. It also has [Read more…] about Wisper 705 Torque Electric Bike Ride Impressions [VIDEO]
