One other option you have may be this...If you paid for the work by credit card you can file a dispute directly with the issuer of the card...The card company will pull the money back and place a hold on the payment until the dispute is concluded...If by chance you did pay by card, I would get the bike and all parts from that shop ASAP, then immediately file the dispute...I pay for all major purchases or work in this manner and the card company generally agrees with the customer...
