Indeed very very nice. Belt drives and ABS are the future for ebikes in my opinion. I hope they consider completing this prototype with front and rear suspension like the new 2020 R&M Delight and SuperDelight.
At present, Stromer engineers working hard to make the Gates2020 as agile and sporty like a typical Stromer. The hardest part is the position, setup and fine tuning of the torque sensor. All Stromer riders know: This benchmark is high. In the concept is foreseen, the frame is ST1 but the equipment shall be ST3.
