...To me the first thing that could be improved is weight by hollowing out some of the parts (I'm thinking rear pivot pieces) and maybe removing the connecting part just in front of the wheel in the rear triangle (I have not seen any ebike with this kind of geometry with a connecting rod there).
The second thing would be geometry, although I'm not an expert on this, and the current geometry seems already great, but if we can improve it, why not ? Something that seems strange to me is the dual pivot behind the motor, where any other ebike has a single pivot (the rear triangle is connected in only one place behind the motor) and I can't see why... If any expert on this could enlighten me, or even advise, that'd be great. EDIT: After looking at it closely I can now guess that it allows the rear triangle to move upwards instead of rotating... I feel dumb now eheh
I'm aware that hollowing out little parts won't do much, but a few grams here and there quickly add to half, or even a full kilo, which is great !
