Have one for every bike
This mount should be on every bike you own if you have a Garmin unit. It attaches with rubber bands so you don't want to be moving it from one bike to the next. It can rotate to mount on either your stem or handlebar. It's dead simple and works, the unit will never eject. I personally don't understand why people like the Bar Fly so much. For $10 this is all you need, and it's not like your speed or altitude will increase with a more expensive mount.
