Pedal sensor for Magnum e-bikes

This is the replacement pedal sensor for a Magnum e-bike. 

It sits over the left hand crank axle, so you need to be able to remove the left hand crank to fit this (requires bike tool - 'square taper crank puller'). 

Although this comes equipped with a plug on the end, the reality is that you have to cut and solder it to the Magnum controllor. The Magnum controllor comes with a pedal sensor hard wired into it, so it is not 'plug and play'.
