For just an extra £50, this upgrade package includes a Pedal Assistance System that senses your pedalling and gives you automatic assistance, i.e. you do not have to press the throttle throughout your journey. Also included is a handlebar dashboard allowing you to shift between three power levels; low, medium or high. Although this is an optional upgrade, you are highly recommended to install a Pedal Assistance System as it will transform your riding experience and improve the longevity of the battery.
Compatible only with the 250W and 500W motors (not the 1000W motor).
IMPORTANT: The bottom bracket on your bike needs to be a Square Taper type (which is the most common bottom bracket on ordinary bikes). If you don’t have a Square taper bottom bracket, you may need to replace it to make your bike compatible with the PAS. Correct installation of a Square taper bottom bracket can be found on various tutorials online.
