I just went on their site, and they’re charging everybody $532 for the KH 29

And it comes with the double-hole cranks, too. 
So is there a difference between the one I linked and the one that’s sitting there at the “special” price you mentioned??
Well I was told he can’t sell them at that price anymore except for the one he has in stock right now.
I am in no way affillated with Bikesonline. I feel that I got a good deal and there is one left. I am just letting you all know about it.

I just got my KH 24 from Bikesonline.com too. It’s the 2009 model for $471. It cost $14 to ship. I really like it but it did not come with the brake mount thing that goes under the seat. The specs say it does. I have been trying to contact bikes online about it but they do not respond. I don’t think I should have to buy this piece since it is supposed to come with the unicycle. I have Magura brakes waiting to install. Other than that, it’s a great uni.
And I’m just asking if there’s a difference. 
I hope you don’t feel I was “attacking” your reply. It was not my intent.
I don’t think there is any difference.
