Mountain Bike

Even if it is not designed for Moutain biking, the H-Zontal allows to go through forest roards. You can support yourself on your arms and legs to absorb the unevenness of the roard, but not for a long ride. To go uphill, the pelvis well maintained allows to give off all the power needed to pass over such unevenness.

However, the H-Zontal hasn't been designed for moutain biking. The main reason to place the cyclist in a prone position is for aerodynamics. Now, going uphill with a moutain bike the speed isn't fast enough so that the aerodynamics has no effect on the performance ; and going downhill, you look first of all after a good braking.  But theses images show you how easy you can ride it (as a classic bike). In town or on the road, you could go up on a pavement, ride very slowly or in a narrow way.
