Super low gears will let you tow loads up mountain roads that you will fall over if just on 2 wheels ..
for example a MountainTamer Quad Crank 16t Granny Gear turning a 36t cassette cog in a 26" Wheel is an 11.5" gear.
A Velo-mobile is a trike with a streamlined body , it's aerodynamic body around the rider
Lets it be it faster on the flat and downhills if the rider pushes it to do so.
