Hello! My naighbor would like to get into riding wit me and she is asking me what kind of bike she should get.. she is about 5' 6" and about 110-125 lbs. I am thinking something like the XR100 or something.. oh btw her budget is about 500-600 dollars.. what do you guys think a good starter bike would be? REMEMBER: SHE HAS NEVER RODE BEFORE! I want to get her something where she could fit confortablly, but not have so much power it would scare her or get her hurt.. not something like a 50..
