All shots from the back of my bike were done at speed, riding free hands, focussing and framing with the Mono + 35/2 wide open (it was dark, hence ISO800+).
The pack was riding fast (!) through Shanghai at night in normal traffic on open roads.
I chose the Mono, as it's great at high ISO and as fast to shoot, small and light, as any Leica M.
I used the Mono with a standard Leica strap cross body, so I could grab the camera at all times ready to shoot.
The standard strap is also great, as it comes off the camera for a quick rinse and wash after riding and sweating.
I used several digital Leica M bodies since the M8.2 and still keep all of them.
None of my digital M bodies shows any signs of RF alignment out of order what would normally expected (I calibrate my camera's RF ~ once a year, before important uses I double check bodies and lenses with focus targets and touch up the RF setting seldomly).
I carry one or two Leica M digitals in a bag with me every day at all times, driving, riding, walking, jumping. Bags get bumped, stuffed, crunched and sometimes thrown.
I never had a Leica RF out of alignment due to normal handling.
I never had a Leica M falling either though - knocking wood.
Take your Leica M9 out there.
It was made to shoot pictures, not to be a shelf queen or be babied with a collection of precious glass case collectables.
Even current Leica digital Ms are tough cameras and can take more than the regular user would ever throw at them.
You should be more concerned your M9 hurting you on a bike than you hurting your M9. It's a brick of solid metal, potentially knocking you into hospital, no matter where you stick it on a bike.
