I have improved the Fixed Gear transmission. My "Newfix" with two fixed gears weighing 17.5 kg already travels faster than my standard Polo & Bike 10.4 kg!
I am old, 58 years old and weighing 100 kg, next season I will try to accelerate it to the speeds of a road bike.
I think this is not a stillborn project, but a bicycle of the future. If we carry out work on weight loss, aerodynamics, geometry for young and strong athletes, then it will be possible to show record results on it.
