What is the pedelec sensor (PAS) for?
The pedelec system uses a little magnetic device that is fixed to the pedal crank at the frame of the bike and has a wire running to the motor controller. It measures how fast you are pedalling and can be used to engage the motor to provide certain ratios of motor power to pedal power – generally in the ratio of 1:1. It is a typical European thing because of laws, some people do like it though. We can provide one but we rarely install it due to no need and no wish to have additional wiring. In our opinion, the throttle is the better system and is safer too. We find the pedelec system to be quite annoying and dangerous, it engages the motor any time you pedal the bicycle and this is not ideal when wishing to ride slowly near traffic or populated areas.
