I don't have its specs, just what's written on it: 24V200 and what I was told when I bought it. It weights 3Kg, I guess these motors are rated just to pass regulations.

The motor spoke holes diameter is 130mm is that your size?

RDV, I'm planning to purchase a second hand Dahon speed (or something similar). Unlike new technology (and batteries), bikes don't change that much over year. So purchasing a Dahon speed 7 at 350$ would be of great value. How do you do to change the part? Can you just get completely different derailleur for example?

I'm also considering the Downtube FS (http://www.downtube.com/Full_Suspension ... _Bike.html). But UK prices are high and it's difficult to find a second hand one.

Wattever, is the spoke holes diameter equivalent to the fork dropout size? I'm not sure how to calculate that. BTW, the MXUS 350W weight 3 kg and the Cute100 weight 2.1 kg.

Wattever, I just quickly mesured it with my ruler. The spoke holes diameter is around 130 mm. Same as yours.

RVD, could you reuse your existing 7 gear cassette on the motor, or did you buy a new one?
