A running friend is looking for a used bike for her daughter and has asked me to find it. She wants a straight handlebar bike, so either a mountain bike or a hybrid. The mom rides a 10 year old entry level Trek with an iffy front shock and loves it, so the bar is set pretty low. Just just wants something her daughter can ride so they can ride together. It doesn't even need a shock; it will only be used riding on greenways... no dirt.
Ideally, I'd like to find a Cannondale, Trek, Specialized, but no luck finding them so far. I'm finding lots of Raleighs and Schwinns on Craigslist for under $200. I'm wondering if a Raleigh or Schwinn would be okay if it had Shimano or Sram derailleurs? I don't want to get her a bike that doesn't shift properly. Any suggestions?
