Electric bikes and kits may be differentiated in several ways, such as by the Wattage of the electric drive system and how the power is activated and controlled by the rider:
By law up to 750 Watt of power.
On the 'pedal activated' bike the rider engages the motor when pedaling. Here are two ways this is accomplished, viz.:
Rotation sensing
The power system engages when it senses that the pedal crank arms
rotate. All bikes listed here are 'dual mode' as well: iZip Metro, Path,
Vibe & Zuma; Kinetic Expedir, 'Forza', 'Forza EV', Quando, Sprint &
Torq, and Kinetic kits.
Torque sensing
This design senses torque, i.e. pedal pressure. The motor responds
instantaneously and proportionally when you pedal: eFlow (dual mode),
Giant Twist, iZip Ultra (dual mode), Stromer (dual mode), and BionX kits
(dual mode).
The rider applies the power manually from the handle bar with a twist grip. All these bikes are dual mode as well , i.e. throttle plus pedal activation: eFlow; iZip Metro, Path, Vibe & Zuma; Kinetic Expedir, 'Forza', 'Forza EV', Sprint, Torq & Quando; Stromer. The kits are dual mode as well: BionX and Kinetic.
Offers the rider the instant back & forth choice between throttle operation and pedal activation. All bikes we currently offer are dual mode, except the Giant Twist and the E-BikeKit kit.
