JakiChan, I have no input, just a request. I'm also a clyde and a rec rider that has lost weight and likes to push himself. I don't want to race, but I like the idea of becoming the best cyclist I can be just for my own fitness and weight loss reasons.
So, if you figure out how a rec clyde can best use that thing, please come back and share. I'd love to hear how it worked for your purposes.
Good luck.
