This bikes existence makes me question why others cost so much. like xtracycle addon kit. ive had nothing but trouble with mine and replacing it with this bike. I like that all the stuff is included on it. a strand to hold the bike up. xtracycle would charge like $80 or something for that. when I buy one it will get a good testing. I do alot of heavy hauling. extracycle didnt like that very much lol
