I'd wild guess that Walmart's probably getting the Thrusters for $25 or so, maybe spends $5-10 apiece distributing them throughout North America. You go to China and make some bids on a couple hundred containers full of 'em and you could maybe get a similar deal.
ok I have to be honest, I picked on up at a pawn shop for $40.00 because I thought it would be a great way to venture into fixies. after repacking the berrings a bit of cleaning I got a bike that is a blast to ride. I don't worry about it getting stolen, hell I have more in the seat than the bike...lol.
you get what you pay for, but, I would not hesitate to buy one given the cost...it is a bike you can afford to hang on the garage wall if you don't like it. in all honesty I am not shure there is not much to dislike on these
