That's unfortunate, not much can be done about the seating position, in stock form. If you're after an upright position, you can look into a curved handlebar.Wallke finally realized that there is something wrong with my bike. They are sending me a new display and control box... I am not too impressed with the power of this bike... Probably 22mph with full throttle on level... This is a quality bike, but I don't like the seating position compared to my 20 inch fat tire folding bike... It's much more comfortable, and the Bafang motor has more power as it is geared.
Once Wallke sorts out your controller issue, you should see 27 - 29 mph.
