Hi Guys,
New here looking for some advice. I am in market for a used bike and I can get one of three bikes in the range of $200-$250 Canadian, which one you recommend? or maybe are there any better choices? the usage would be recreational only, mostly on side walks or park trails. I would greatly appreciate your help.
