If it is difficult to peddle start a bike you might try changing the front peddle sprocket for a smaller one or the rear sprocket for a larger one , or both . My bike is a two speed . It is very difficult to peddle to start in second gear but easy in first . A single speed usually has a general purpose sprocket ratio and is harder to start from a stop than a multi speed .
Building a strong stationary stand to start a bike with , at home , is always an option . ..... D.J.
My stand is too delicate to be used for stationary starts .
