I'd like to get a helmet cam in case of accidents. ....and mount it on the bike instead of the helmet. I have no illusions about the tedium of my riding for other viewers - i'd prefer something that recorded the last x minutes of riding without a reset. i'm not sure if the usual products do this (contour, go pro)

anyone have a setup that they like?

thanks,
matt

If you want to mount it on the bike rather than the helmet, the Cerevellum Hindsight gives you a rearview camera display -

Video Recording
The systems records video in a continuous 5-minute loop, stopping automatically if the bike is laid over.

I don't know if this is great or not though - I might want it to keep recording after the accident to record what was said.
