Uphill the speed is slower than an ordinary e-bike due to larger mass. Due to the advantage of four wheels, it is, therefore, more stable than a regular cargo bike with two or three wheels. It also has a good electric automatic gear that is integrated with the motor solution.
On flat ground there is faster speed due to low air resistance.
Downhill the speed is faster due to the heavier weight and low air resistance. Maximum speed is 50km/h downhill (by automatic breaking system).
