Hello everyone, i recently bought a Grubee Skyhawk 2011 GT5 from gasbike.net, i own a Santa Cruz cruiser bicycle and the bicycle i have the motor on. The pro blem i have is its hard to move the bike, the back tire skids, i think its the chain because when i take the motor chain off and use the pedal chain, everything is fine. I tightened up the chain with the chain tensioner and it still locks up. I also made sure that the chain is even with both sprockets and it still does it. I haven't road it yet. Please help : http://i230.photobucket.com/albums/ee217/Aerlinfall/IMG_20121018_224417.jpg
