The Mojo HDR 650b is the fraternal twin brother of the Mojo HDR and the younger brother of the Mojo HD, taking the HDs technology and versatility a few steps further. As you can tell by the name, the HDR 650b features that third wheel size that all the kids are talking about these days: 650b / 27.5".

Highlights are below. If you want to hear the story of how this bike came about, head over to the story tab. The details tab will give you a lot of technical info about the bike.

Maybe the best place to start would be the galleries tab, where we've got a few videos showing the bike in action along with some lovely big studio shots.
