1.3. PAS & Throttle
Due to the powerful support of the motor, the rider will approach high speeds much faster than
when riding a conventional bicycle. To get used to this effect, and for your safety, we advise you to
first use the e-bike in a familiar setting without too much traffic in the surrounding area, when
driving it for the first time. When you first start biking, be aware of the electrical powered acceler-
ation that will instantly be provided by the motor. We advise using the lowest power level when
driving for the first time. When switching off pedal assistance, the e-bike can still be used just like
a regular bike. However, please note that when biking without using the battery, the lights of the
e-bike will not be in operation. When set at level 1 or above, the throttle will be on and will
provide smooth acceleration. If the throttle, brake lever, pedal assistance, or lighting are function-
ing abnormally, intermittently, or not working, please stop using your e-bike immediately. With
the throttle on-demand feature, you can use the throttle from a complete stop, rather than
pedaling first, which can help when riding up steep hills or through an area with lots of stop
signs. However, as a general practice, we recommend pedaling first, and before engaging the
throttle, whenever and wherever possible.
