There’s about 15 minutes of learning to get used to the oscillating bar, and perhaps one hour training to master it.
The system may be forbidden by some governments. Please do check and respect the law of the land.
We imperiously demand that you do not use the oscillating bar on roads with engine vehicle circulation until you perfectly master the use of it.
The wheels, the pedals, and the pedal axle do not turn backwards.
The bar does not do sharp turns when the pedals are not turning. There is some leeway so that there is no problem keeping the equilibrium on a road with no sharp turn, even if the pedals are not turning.
The left pedal is displaced a bit more than one inch on the outside.
This first model is not suited for persons over 85 kilos.
so you can’t slow down or back pedal or turn sharply
