South Philly Bike Shop

This is literally the only bike shop I've been to that doesn't make me clench up when I go inside. As in, they're super friendly and welcoming, and don't have that why-are-you-invading-our-sacred-bike-space vibe. Just for that I'd give them 5 stars, but they've also been really helpful and effective every time I've gone in (for repairs & buying stuff). They also basically found/put together my "dream bike" and sold it to me for cheaper than they could have. Months later I still love it. Good (not huge) used bike selection. Etc. These guys are the best!
