I have a Speedfight 2!!!! the wheel is pretty heavy but pretty satisfyling to navigate in the dust and fields with... I ended up taking some wrong turns on mine, going down a ravine and having to go up again, juddering through corn fields that were felt like a rodeo ride, and getting lost in some wet muddy woods that i thought were 1 km wide but in fact were about 10 kilometers... it has very good handling.
But WHAT is this thing? with the rubber? the back axle goes through the square area? a kind of schematic sketch on paper would have helped me figure out what is happening at the back of that scooter!
how many inches of suspension are happening at the back? depends if you off road, but for general purpose, maybe 2-3 inches makes a more controlled and comfy ride if there are bumps. What would have sprung to my mind is a pivot with a coil or leaf suspension, maybe even some air suspension like a tennis ball or a larger volume of polyurethane.
I was amazed that you stripped that bike totally, i thought you would put the battery in the saddle and take off all but the frame and the excellent outer shell on the speedfight. really i would have kept the back suspension!!! Piolini!!! it rocks! Oh my god.
amazing tools and engineering!
