About this Product
Still some issues with the headset on this version but the gears really function and turn the back wheel!
To solve the headset wobble I super glued it in which makes it stop functioning like a real bike.
Also, because there is a +/-.15mm accuracy with the strong flexible material and my model is relatively small, the model you receive may need some DIY tweaking. For example, the model I received had some issues with the rear gear fitting through the rear wheel. I just used some sand paper and got the cylinder thin enough to fit through.
