ECX Circuit Wheelie bar
thingiverse
This custom Wheelie bar originated from a design created by @kosm0 as its foundation. The corresponding part number fits multiple ECX models perfectly, but I have only successfully tested it on a Circuit. The designed Wheelie bar relies on a body pin and two bearings sourced from a fidget spinner for optimal functionality. Specifically, the axle measures 8mm in diameter, while each bearing is 7mm wide.
