how is your opinion on electric bicycles?
i recently started my apprenticeship and im currently riding my bike to and from work, 8km each. which is currently the only kind of sports i do. i am getting an e-bike mostly to cover days when i dont feel fit enough to cycle the whole way by myself.

by only biking, i figure my upper body isnt getting any workout, is there a routine you can recommend to complement cycling?
