This is a discontinued model. Its replacement is the CHANGE 809 folding mountain bike.

The CHANGE Bike 609 is a lightweight folding mountain bike that’s incredibly easy to stow away, travel with, and ride. This fold-up mountain bike features 27 speeds and is engineered for easy climbing and descent.
