Yamaha PW-ST motor - EU 25 km/h ( 15 mph) in great condition. done a little over 500 miles.. all other parts currently available. Slightly higher cadence support than a PW take off from a haibike - and no its not a PWX and it wont fit a giant. I'll throw a set of worn crank arms in the box (170 mm) Low low price.
