Bicycle with Boosters

Of course, though an electric motor and a battery provides better power-to-weight and more energy-stored-to-weight relationships, important for a predominantly muscle-powered vehicle.

The energy storage Vs thrust capacity of compressed air is dismally small given the realistically small size of cylinders that could be fitted and carried on a bicycle.

However chemical based thrusters would work but you have no throttle or off switch.

Go nuts or die trying when you light them up!

I agree with the electric method.
