I just bought a Bladez Fitness SX Pro (it was on sale at Sears for $699.00 CDN). It's super solid and smooth. It has a 48 lb wheel. So far I'm very happy with the purchase. The seat is hard, but I've gotten used to it. I do plan to buy a softer seat and bike shoes in the future. Also I'm short (at 5'1) and this bike fits me comfortably. So far I'm very happy with my purchase.
