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.
