Assuming that it really is waterproof then its an interesting alternative to a Zumo, but there is no motorcycle mount listed. Also, the power source appears to be a conventional cigar lighter plug so one would have to be wired up where the rain didn't fall (or recharge the internal battery at the end of each ride?). Road Angel have been around for a while but where I work (we sell car parts, cycles and in-car technology) I can't remember when we last sold a Road Angel of any sort.
