Full suspension mountain bikes (also referred to as dual suspension) feature both a rear shock and front fork to cushion bumpy off-road terrain and increase confidence when pushing your limits.
This type of bike makes riding much more comfortable and fast while still giving plenty of confidence boost as you push past limits.
Due to its additional weight and complexity, however, bikes may be less efficient on roads.
