I'm new to cycling and I bought a single speed, windsor clockwork, from bikes direct for a good economical choice for getting started. I love riding the bike and I believe it's quality suits my needs fine. I only ride 20-30 miles at a time and I don't have any complaints about it. But unfortunately I backed over the rear wheel and it has a good bend in it that is just too annoying to ride with. I have to widen the break pads real wide and it just has so much wobble it feels inefficient. What would be the best option to replace the wheel, when I go to to the LBS most wheels cost nearly a 3rd as much as the bike. But maybe it's worth the upgrade, I don't know. I plan on riding road bikes for a time to come so maybe a quality wheel or wheel set would be a good investment and in the future I could upgrade to a better bike and I already have quality wheels. Thanks for advice
As was stated, post up a video, because if you are still able to ride on it (which is how it sounds from your post), it should be repairable (as was stated).
If not, a quick eBay search resulted in a few $60 and $80 rear wheels. You could also contact Velomine or Retrogression to inquire about just a rear wheel (neither site has just the rear advertised, but it shouldnt be too difficult to acquire one).
If you have a co-op in your area they will most likely be able to assist you in finding a used wheel.
