I use this on all my bikes, 3 road bikes and a power assisted grocery getter. One of the road bikes I've had for almost 49 years and bikes that old use a quill stem which is not compatible with the stock bracket that comes with the Padrone computer. I would then mount the computer on the top tube close to the head tube and in riding the bike I would occasionally hit it with my knee and knock it off one time that this happened I turned around just in time to see it being run over by the right front wheel of a car, then I discovered the out front bracket and it works perfectly, the computer is in a better position to see and it is in a position where I can't accidentally knock it off also the E bikes stem is not compatible with the stock bracket so I am able to mount the Padrone on that bike with the out front bracket,
