I replaced the chains today, out of my stash of stuff. Of course one chain is longer than the usual bicycle chain and the other one shorter than the norm but I worked it out. The gearing is good on this thing and with new chains it pedals nice. It's quite fun to ride. I experimented a little on one chrome rim and the chrome front fender, pretty much the only chrome on it, and I believe they will clean up nicely. If not I will replace both rear rims and the front fender, no big deal. Rear fenders were an option on these and I might add them on too. It appears that the manufacturers used existing parts in the builds, and nothing except the frame and "handlebars" were built in-house so parts won't be hard to find. I checked with the manufacturer in Florida and I can get the decal set. I've ordered some rear tires that are black with blue walls. The front will certainly be the first time I've ever ordered a 12.5" tire!
