Hi, I just sold my motorbike and bought a Stromer St1 ( 14,5 Ah battery ) to go to work and back 2 times a week ( round 50 km one way ). And I'm very happy with it. The only thing is the range. It's winter here in Belgium, which means round 2 to 6 degrees celsius. And in position 1 and 2 I can only just make it to my work. But after 50 km ( 30 miles ) the battery is empty and I didn't use position 3 or 4. Is this normal? My weight is 82 kilo ( 180 lb ) and if I do this track ( which is pretty flat, well, Belgium ... ) with my normal bike I have an average speed of round 24 km per hour. With my Stromer, position 1 and 2, I have an average speed of 33 km an hour. But I also must say that I have been working pretty hard then. In the shop they told me that 50 km shouldn't be a problem in position 4. But my experience is different. Anyone? Thank you so much.
