The bike mount is solid rubber and should last well. It stayed in place very well on a 40km single track mountain bike ride. It's abit heavier than I expected and the tie wraps are difficult to use, leaving the end of them sticking out making the watch strap sitting on the sharp ends. Ultimately, it's better than trying to look at my watch on my arm while riding in difficult terrain and I would likely buy it again.
My partner is turning into an avid cyclist and wished to use her Garmin 610 that she used for running while using her new road bike. This is the perfect solution. Very simple design with extremely quick and easy install. This allowed her to transfer her Garmin from her arm to the handle bars and re-focus her valuable attention out on the road, where it should be. My only critique would be that it would be nice if Garmin included some more of their zip ties in case we ever have to remove the mount for bike maintenance or if they snap but I'm hoping they will be standard size so I can just use some from an automotive store. Great product, simple design = perfect addition to an exercise arsenal!
