Well, it sounds on the website like its a scooter, which usually means no pedals. But they haven't released much information either, really..
If you wanted a real offroad e-bike, the best way to go would probably be to find a chain drive unit that let you mount full suspension, pick a good frame, pack on a little extra voltage and that should do it.
My 408 at 48v had more than enough power to turn off-roading into a real fast ride, and one of the 5-series motors would rip anything you could throw at it to pieces. You could probably get good results out of a rear drive version, the only thing i'd be worried about is the amount of heavy abuse the hub would take, which would be where the suggestion for a chain drive unit would come from. Then again, they might take a lot of abuse, I just haven't gone out to find out
