Also, I'd be VERY careful about frying the motor, that's 2000 watts through a motor rated at 250-350 watts. BigH fried a 408 at 72v 20 amps I think, maybe 35 amps, and it's A LOT bigger motor.
If you go faster than 45kmh I think suspension is a good idea, at least front suspension.
Your rim has 32 spokes, ebike motors typically have 36 spokes, at least in my experience.
And the front end will be heavy as it is, I'd be VERY scared of that front rack, you'll lose the front end...I've done that twice now, although never under power, just lost traction cornering.

Umm, you plan on going straight to a 2000w setup....ten times the legal limit.
What was that you were saying about cyclist first?
But I do agree about the $100 POS walmart bikes. Unfortunately it's harder to marry the e bike gear to a more expensive bike (9 speeds, no V-brake pins on the rear wheel, stuff like that), but I'd never trust a toy bike to stand up the abuse my bike gets!

It looks practical for commuting & carrying stuff I plan to stay a cyclist first, ebiker second. I suspect your in a similar situation. I don't understand $100 bikes with $3k of ebike kit on them. Nice to see a few decent bikes around.
sounds like a plan, and quote do-able. You must admit Toshi's torque arms look sweet though! If I had a disc mount welded on I might have a torque arm mount done at the same time, we'll see.Mark_A_W wrote:If you are using a steel fork, just cut yourself some torque arms from some 3-4mm stainless sheet with a jigsaw and files. Knoxie did this.
And stop worrying about the weight. You'll find it's completely irrelevant...until you have your first electrical failure and you have to pedal it up a hill (so don't ditch the low gears!).
