No. It's actually MUCH harder. The head angle of the bike is rediculously steep, like usually 74 degrees + compaired to like 69 degrees for a steep street mtb.
The common techneque used by trials riders to produce a hop is called a pedal kick. This is where the kicking of the pedals creates upward momentum, and the rider hops the bike.
p.s
20" wheels, the 1 foot grind of the trials world.
