What about the geometry of the bike? How does it ride and handles?
Glad you posted this video.
Well I guess one way to solve these problems would be to ask the company to just sell a rolling chassis. Frame, wheels, shock, fork and possible brakes if they can accept to put in quality brake. As you said, at least in the front. A frame kit would feel way less risky to put money into and I for sure would give em a try for a frame kit or a rolling chassis. Then I could decide what motor, controller, bms etc to use.
Maybe this can be an opportunity for real world testing of the frames? They are lacking in their testing department as I got contradicting max rider weight from them and even if I continue to ask they give me various answer. I got so far from 90 kilo to 110 kilo iirc. I mean max rider weight should be easy for them to find, because they should have at least done some computer simulation of their frame, but it seems they have not.
Check with them Artur if they are willing to do frame kits or rolling chassis, in the end I am sure they will benefit too from real world testing and review from the ES crowd as some of you guy got mad skills and experience. And they can be sure their frame will be used in a harsh way by many here
