MTB

The MTB is the larger of the Free Rider HD bikes. It is also the most common bike used in Free Rider HD. 
It is considered by most far better than the BMX bike for many reasons including:
* It has a lower center of gravity. This means that it is less likely to topple over whilst on straight ground.
* Its wheels are bigger. This makes it easier to ride over bumps/small spikes/small vertical extensions in the track
* it spins a little bit slower than the BMX, resulting in much smoother flips
When creating tracks it is the "default" vehicle.
