Assisted Ranges
Battery Size | Range | Range |

Note: Rider weight, load carried on the bike, terrain, tyre pressures, speed, power settings, wind conditions, and motor power all have a huge bearing on the range. With this in mind, the stated ranges above are averages achieved in testing.
Cadence vs. Torque
Wisper classic electric bikes are available with either a Cadence sensor or a Torque sensor − they are otherwise identical in specifications asides from a the presence of a Tourque sensor located around the crankarms on the Torque sensor eqipped version.
This sensor measures the power being applied through the crankarms when the rider pedals and instructs the motor to assist immediately as the rider begins to pedal. This is particularly advantageous for hill starts whereas the standard version uses only a cadence sensor which triggers motor assistance only once the bike is underway.
