I'd take the Flow trails over the Flow park. It's not worth the extra $$ just to have the gyro, and yeah I'd take a flow over the Bel air too. I don't like the 8t driver and 23t sprocket, seems to scetch of a set up. The cranks are gross, I hate primo cranks, and pritty much primo anything because primo is gay. The stem is a brick that slips alot, and the price is too much. The Flow comes with better components IMO and is cheaper.
