Best Place to Get a Used Bicycle - 2011
Let's say you're the type of person who loves to ride a bike but isn't necessarily a fanatic about the accoutrements — fancy bike shorts and little caps and things like that — or having some absolute top-of-the-line $5K wheels. Let's say you just want something that will reliably get you from point A to point B and you don't want to break the bank getting it. Cyclone is your place. While the true masters of hardcore racing will prefer higher-end shops like Boone's and West End, Cyclone is the first-call spot for dirty riders who prefer the sidewalks and wear their street clothes. Uniquely in Houston, Cyclone sells lots of used bikes and accepts trade-ins, so if that temperamental skinny-tired road bike isn't working for you, you can wheel that prima donna into Cyclone and ride off on a rugged mountain bike, occasionally as an even swap.
