Converting a Fixie bike to Electric?

[chopper_elec]

Hey all,
I've got a new bike at the moment and i've been considering converting it to electric. The back wheel does run a FLIPFLOP design which would allow me to use a free wheel and a fixed cassette which would be perfect for a non hub style motor.

my only issue is that I didn't want to make any holes or welds in the frame and wanted to be able to convert it back to standard if required.

Any advice on using a non hub style with this particular frame?

A kepler drive or commuter booster under the cranks might be go. Kepler and Adrian are both from Melb, have met them both on our group rides, great blokes.

Or a thin magic pie hidden in the back under some leather panniers, full of lipo and a cheap 9fet or KU60 controller or the like. Toss the stock internal controller.

You mean "fixed cog"? Cassette = multiple cogs.

I'm assuming you are planning of using parallel chain drive. It will be tricky to make it work since both threads are the same direction. There should be a lock ring on the fixed side with smaller dia reverse thread, but I wouldn't put much power through it.. Could change to a hub with disc brake mount

Thanks heaps for that link. I may end up investigating in a friction drive due to convenience. The hub motor in a 700c configuration may end up being easier by the looks of things.
