    From info on the endless sphere forum... Code 10 is 310 rpm Code 11 is 285 rpm Code 15 is 206 rpm So my guess is its around the 250 mark. This is all from a 36v input. Obviously you can over volt etc to get more out of it.

    Hill climbing vs speed - kit options

    If you wanted a cheap kit think andy is selling a 350watt direct drive for a bargin price. That also has a delta and wye feature for low speed and high speed. If i would have seen it earlier i would have purchased before going down the china route.

    Can you not just buy chain drive kits though? The only thing I can really see the benifit of doing this is if you had a spare motor doing nothing. Else your using a motor not intended or build for that purpose. Also it would work better with a Direct drive as they have beeter cooling.
