I just picked up a Cateye Micro, but the instructions say the unit needs to be within 70cm (~27") of the transmitter. With my Dahon Mu P24, that means it won't work from my handlebars. I'm thinking about mounting it on the bar post or perhaps on the frame, but neither of those options make for easy reading. Are there any units that have a longer range? How are you guys, if any, using a wireless unit with your folders?
