Technic LEGO Chopper instructions for the serious LEGO fan!
The BadCat Chopper is a 100% Technic LEGO build. We centered the design around the LEGO engine with the crankshaft and pistons. Our goal was to connect the rear wheel with the engine so the pistons move up and down as the bike moves forward. Getting the look and function we wanted was a challenge, but after several design changes… everything came together.
The BadCat Chopper is an awesome design with a working engine, steering, and fat tires that allow the bike to stand upright. If you like functional designs with a little technical detail, the BadCat Chopper is for you!
