Fantastic E-bike built off a super durable Surly 1x1 frame. Range is around 50-70 km with a top speed of around 40 km/h. I have maintained it diligently since I bought it in 2019 and it has never given me any problems. It was always a bit small for me and now I don't have room to keep it. My loss is your gain!
