knuckle type is OK for motorbikes but steer angle not enough for bicycle because your feet can't reach the ground,so I redesign the knuckle, turning rod end joint 90 degree
Now the steering angle and tilting are fine but the main column of the mod kit is too skinny to run over big obstacles,steel cylinder tube should be better like the 3D drawing as shown next version will be seen
Since the front kit a little too heavy (6kg+)for human powered vehicle,gas or electrical powered bike mayt be a better style
