Looks like im screwed . Oh well. I got a new seat, ultra wide 13.7 inches , and maybe that will make the 35km/h speed ok. Before the seat was uncomfortable , and therefore I was upset with the bike, and therefore I really wanted it to go faster to compensate. I posted this question on Reddit and they shamed me And downvoted the question. This forum is much better. I suppose this is goodbye, and thank you. Unless of course the support company is lying. They did lie before, they wrote a review , posing as a customer , for the e-bike saying it is ul certified. It disturbed me to find out it isn’t until I learned that ul batteries explode too.
