Ottodog, I had some of the same problems with the Falco 500W kit. Poor instructions with the kit, loose spokes out of the box, and I found the ANT+ programming really obtuse until I got a lot of help from Rakesh. Now that I've learned how to set up the performance parameters, I like the kit, and for those of us who don't enjoy spending all day breathing solder fumes, I like having something that I can plug in and adjust. I installed the kit on a LWB recumbent, which seems to scare dealers, so I just read the instructions, such as they are, and ask a lot of questions. Followed the same procedure in 2007 with a Bionx PL350, and we've been real happy with that also. Still using that conversion kit with around 18,000 miles on it, with a few battery changes. Takes some patience and perseverance, but hey......
