Hey all, I'm from OC, California. I was riding back from the beach, bodyboard in a bag on my back (it's much easier with the onshores pedaling back) when I caught up with a guy who had both a gas motor and an electric motor in his hub. I slowed down and asked him what was up. He clued me into the motor bicycle scene, and I went home, started clicking around and ended up on Craigslist. Found a local guy who was selling Grubee's (80cc's) for a little over $200. I bought it and installed it over a two day period. Well really a day and a half, and then putted around with it. Then I found this site. I should have done that first, but I have been very happy with my install. I'm using a 10 year old mountain bike which I rode around quite a bit. I'm a little worried about something seizing and throwing me off. I take the motor out for 2-15 miles a day, trying to do the right thing breaking it in, but I am constantly worrying about something seizing and throwing me. I've never had anything 2 wheels which was powered by anything other than my legs. The biggest problem I've had is the chain tensioner. No matter how much I tightened it up, it would end up slipping and the chain would bind right around the engine sprocket. It actually got so bad that it blew a little chunk of metal from the top cover of the sprocket. At that point I went to my local Ace's and bought a bolt and washer, installed that so that the tensioner couldn't slide down (I would post pictures but I don't have a digital) and I haven't had any problems so far. It has only been about a week though. A couple of issues I've had: Most of my noise seems to be coming from the heavy chain and where I ride I really don't want to piss off the natives. Would a lighter chain from Dax help that? I was thinking about just carrying around a pliers to take out the master link when I just want to pedal. Anyone have any other idea? That's about it. I hope this thing lasts for another couple of months. I'm having fun. Oh yeah, because this is an introduction, I'm 37, recently divorced (so I don't have the same permission problems that many on this board seem to have), and I'm a teacher. So I'm just having fun this summer.
