I'm on an internship through the first week of August. A bike would make my life a lot easier (ten minute walk to my lab, and it would be nice to be able to bike into town instead of driving). There are two or three bike shops in town, but I haven't had a chance to visit them yet (they're actually very close to each other, which is nice). Is it common for bike shops to allow a "very short term lease" of one of their bikes? A used bike in poor condition would be alright. Or if not, how inexpensive is it possible to get a used bike for road use? Do you guys have some tips for dealing with local bike shops so I can better prepare myself for it? This is pretty much a college town, if that makes a difference. Thanks!
