I ordered my son the Lancer 250 sports bike (Street bike). For his high school graduation 5/29/2016, I received the bike in a timely manner. But on 8/24/2016 we took a day ride just him and me. On the ride I heard his bike making a noise at the back tire, the bolts that hold the sprocket to the hub had vibrated loose and broke the hub. The metal bolt keepers did not do there job, anyway I ordered replacement parts like a week or so later. I got a parts order # and everything after a few weeks I realized that I had not heard from the company so I tried calling them again and again and again. All I got was the automated system. This went on for week's, so I emailed them. And now it is 11/05/2016 and I get a return email from them finally. No parts but an email! They need to work on customer services I do believe!
