What is throttle control on an electric bicycle?

Electric Bike Throttle Control on eZee Quando

A throttle controller is a twist grip type of control, usually on the right hand grip (just like a scooter or motorcycle). The amount of electric assist from the bicycle’s electric motor is infinitely variable and available EVEN WHEN THE RIDER IS NOT PEDALING.  Jurisdictions such as the European Union (EU) countries stipulate the rider MUST BE PEDALING before the motor can provide assistance. It is possible that a crank sensor (pedal sensor) in conjunction with a throttle control would allow this type of controller to comply with the EU regulations. With a pedal sensor, no pedaling=no power.

What is pedelec control (sometimes called dial control) on an electric bike?

Pedelec Dial Control on a eZee Bike Forte

Pedelec, derived from the terms “pedal” and “electric” is a method of controlling the power on an electric bicycle so that power can only be provided when the rider is pedaling.

The most common type of pedelec is a dial control where the rider sets the dial for a desired level of assistance from the electric motor. YOU MUST BE PEDALING FOR THE ELECTRIC MOTOR TO BE PROVIDING ANY ASSISTANCE. No pedal=No Power.

This type of controller is a requirement for electric bicycles in many jurisdictions such as countries in the EU. Sometimes a pedelec control is described as a “constant tailwind”. As long as the rider is pedaling, no matter how lightly, they will get assistance from the electric motor. The amount of assistance is dependent on the level set on the dial.

So far, based on our experience in Canada and feedback from many riders, the throttle control seems to be more popular. This may be because the rider can go into slacker mode and still get assistance without expending any effort.
