I was looking at the Mac site... I don't see anything about a 2kw Mac hub motor. Where are you finding this?

Why did they decided not to allow ebikes on Pikes Peak? That is incredibly lame.
Mush! Mush you electrons! Push harder!

It's am industrial lawnmower motor, there is a thread or two on it on ES, search for '2kw mac' and '2000w mac', you'll find them.

I have not recieved a reason, Just a shitty attitude from the organizer when i called him up and asked how ebikes should register, then he said he'd get back to me next week.. it's been a month now.. i emailed him, called him 4 times, left a voice mail, even called up everyone i could who participated in the race last year and was told that it really sounds like he's not going to allow ebikes up the hill this year.

So, given that we are a month and a half away from the race, i am taking this as a 'no'.

Oh well, sold the bits off, and will be putting together something much more powerful :)

The all-arounder: 8T MAC motor on a Trek 4500.
The girlfriend bike: 350W front MAC on a 700c Trek.
The wheelie machine: 20" Rear Magic Pie II on a Trek 4300 MTB
The Bus: ??? on a 'da bomb' cargo bike frame

Pro-tips for noobs: Avoid BMS Battery like the plague | Charge RC Lipos to 4.15v, stop discharging at 3.5-3.6v | Use torque plates/arms! | Rear mounted hubs are always best
