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?

Badass custom mofo outrunner 205x177mm 26kv

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.

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.

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!

2 notes...

your upload speed is not great...

is the bicycle wheelie prone?
A decent 25mph bike will cost around $1000.
A decent 35mph bike will cost around $2000.
A $1000 35mph bike will get you killed.
Justin we really appreciate what you did!
