Thanks guys for all the responses. I really wish she hadn't purchased the wireless computer. She had a wired Sigma BC509 on her Sun EZ-3 bent but it had handlebars over a 16" front wheel and it worked great. Sigma has a recumbent harness for that computer for around $10.00 that I was going to order for her from my LBS, but she had already purchased the wireless. This weekend I will go over the bike again and see if I can come up with some way to mount the sensor on the front wheel rather than the back one. I had a feeling that the signal was being blocked by the body and the seat, but never having a wireless on a bent, I wanted to be sure that others have had some of the same issues I am having.

As I said, I have not had any luck with anything from Bontrager and this is no different. The instructions for this computer really suck. It is a single piece of paper printed on both sides and the foreign language parts take up 80% of the instructions. No where does it say anything about maximum distance or body interference or pretty much anything. If I were a first time computer user, I wouldn't even know about having to set the wheel size because it isn't mentioned nor do the instructions really tell you how to do the initiial settings. I had to play with it for about an hour to figure it out.
