I see there is a microswitch in one of the photos of the drop-outs. I am curious as to know what it is used for?

MinV: 93.2
MaxS: 69.7 (CA wasn't reading speed correctly, it was still accelerating)
Wh/mile: 79.6
Miles traveled: 3.9
The race bike:
24s5p 50c nano tech
Badass custom mofo outrunner 205x177mm 26kv
Peak power in : 420A at 87v
Peak power out: 34 Hp and 105ft/lb

Build to last...

Do you think you reached 69.7 or is the wheel size out of whack on the CA? Need video tomorrow.

definitely hit 69mph, not the wheelsize calibration, the CA will flicker between actual speed and an arbitrary nonsensical 56 mph, that's until it hits 70, then it goes to zero while the bike keeps accelerating.

You should be a "proud papa" Farfle.

Thats a badass machine, and you made it yourself. Nothing you can buy can match that level of satisfaction. Savor it my friend.

Yup you need video and dyno tests. I proved with my x5 I can spike what you see in my avitar but it was no faster then something with ~350 amp peaks!

Outstanding work Farfle, definitely an ebike to be proud of. I take it that this one won't have a female pilot, because it will take some balls to ride. :mrgreen:

Actually, if I can get her to ride it again I will, my cousin will be up to ride my friends 9c bike in the 1500w class, and my boss will be racing his hot-rod hx powered bullit cargo bike in the 1500w class aswell.

And sorry again, I cant get you guys a ride video till the 8" of snow we got last night melts off.

You are a wise man. That girl can ride. (Maybe the first time I've ever said that when talking about a vehicle?)

I think her on that bike will have an extremely good chance of winning.

I'm sure Danika can drive too, but couldn't manage 2 laps without crashing at Daytona. :lol: If it's just the power to weight advantage, I've got a couple of fearless sub 100 pounders in training already. :mrgreen: I'm only a male chauvinist when it comes to golfing, hunting, and racing.

70mph?!!!!

I think I just made a mess in my pants.

Well done- that's awesome, although my wife will now officially hate you as I am going to announce to her that I need to make a double stator motor too (but probably not quite as awesome as yours!). Have lathe, mill and welder. Time to play!
