Haudang -P12L Power Sensor Electric Bike Power Pedal Assist Sensor Double Hall Power Sensor Electric Bicycle Conversion Accessories

Easy to fit and does the job.

Bought this to replace the magnetic wheel which fell off my e-bike. Swytch (who’s conversion kit I used) offered to replace it for £20 which I thought was far too much for a small plastic wheel with a few magnets.I only needed the wheel from this product, so can’t comment on the sensor itself. It was easy enough to fit, I needed to remove a few of the plastic spokes to get it round my pedal.Only problem was when securing it with the metal ring. The ring was nowhere near tight enough & came off too easily. It also wasn’t the correct circumference for the magnetic wheel. I ended up ditching it entirely and drilled two small holes on either half of the wheel and securing them together with one of the cable ties (helpfully included, presumably for something else).It works fine, but if you don’t want it to come off mid ride you’d better get your drill ready.
