Is that $450 Canadian? From looking at the specs of this "BB" folder, it looks like it would be comparable to the Citizen Gotham which sells for $274 USD, and that is a fair, and reasonable price for that level of quality.

I noticed in another post you're going to look at the Downtubes, and if you can afford to invest $400+ in a folding bike, that is a good brand to consider.

Good luck.
