Hi Folks. I have enjoyed cycling for many years and just recently my wife and I thought it would be a great idea to purchase a couple of folding bikes to take along with us on road trips. I like the idea of being able to put both bikes in the back of our station wagon instead of hanging bikes on a rack. Being on a fixed income, didn't allow us much room price wise, so we ended up buying two bikes form Campers World (Adventure brand). After riding mine I find I enjoy it more than my mountain bike, but being an inexpensive bike at less that $200, one can't expect any sort of quality with components. As much as the bike handles nice and it's fun to ride, I can see right away that components are going to need swapping out sometime soon. Perhaps new wheels, rear sprocket and new derailleur. My question to you good people is -- any suggestions, without breaking the bank? One thing I have noticed while riding is that after awhile I hear a slight knocking sound coming from the rear assembly. Pedaling backwards for a short time and then resuming the ride the sound goes away. I'm thinking that it might be the cheep Shimano derailleur. One thing for sure, the wheels are in need of truing. Spinning the rear wheel on its stand, the bike vibrates like crazy and while slowing down one can hear slight knocking sounds. At the price I paid for the bikes I had an idea that I would experience slight annoying component issues. If you can suggest inexpensive but relatively decent components that I can eventually swap out I would be grateful.
