a friend asked me to look at her new bike to make it rideable. that was the 1st clue. her husband bought her a cheap bike online but it "wasn't working". I couldn't say no. I mean how bad could a new bike be? she brought it to my home offered to leave it. I thought it might need some minor adjustments. what a pice of cr*p it was. I don't know know how some of the parts were manufactured. I told her the truth & sent her away, with the bike
