In step 5, it drives 25 km / h even if one occurs only very slowly (+/- depending on the wind strength) on the pedals! (You will really lazy :))
The engine is very strong and because that bike is not so difficult, it speeds up almost like a moped :)
The battery lasts at stage 5 and so 20-25km from level 3 with easily with Tretten 35-40!
By folding it well past the car!
I recommend it because of price Top!
