I went searching for a good quality used bike this weekend, and took along an experienced cycling friend to help me find a really good bike for my size and biking needs. We found this place on the internet and stopped by. It's an adorable little neighborhood shop, with a really huge selection of used bikes (they only have a couple of bikes shown on their website, they really have much more than that). Everything was very reasonably priced, and in good repair. My cyclist friend was very impressed by their honesty--if they said a certain part was in good or poor quality, or had a certain amount of wear, they were telling the truth every time.
Although I did not find a bike for me at this place, I still am very glad that I visited. My friend and I already told our other friends in CU about this place. If you are looking for a used bike, this is the first place you need to check out.
