The only small engines available were lawn mower engines. Usually about 1 1/2 hp. flat head engines. The keyway hubs on those wheels rattle about a bit (although they can't move anywhere because they're wedged in nice and tightly with spacers.I might try a shim or two or just accept that this is a home-made rig and won't expect the ride quality of a BMW GS. WARNING: Since a lot of this was learning on the job, the photos/steps are not perfect. That said I'll make every effort to include enough information in the text for you to be successful. I also reverse-engineered some rough plans and a CAD model of the frame which should help! If you don't fancy a torque converter, a traditional centrifugal clutch like this one will work fine.

Bend the pieces shown in the plans using a 3" CLR die. The digital level comes in to ensure both sides of the symmetrical 'U' shape pieces are straight. As you can see from the pics, mine didn't turn out totally level because I didn't take enough care. That said, it was possible to fiddle things later on to make them line up better.

Fit the tank - I found some runner door stops that made the perfect petrol tank mount. All that was required was to weld on a metal rod for them to slot over. Not a great picture but you can see all this on the picture of the frame sprayed. Adjust so that the calliper mount is in a position that you can get a good weld against the rear stay. After I finished the frame, I measured things and sketched up some rough plans (see the files section for the PDF). Plus, boasting a 120 psi pump, it’s another extremely powerful piece of kit, and can repair much more than just bikes, including footballs and basketballs.

Damaged, but repairable washing machine engines were hence reborn into a new roll of becoming the main power source for the various military installations Duddel Bug creations.

Versatility in Design: Our Mini Bike Frames come in various styles, ensuring you have options that not only perform well but also make a statement. Cut the 1M axle in half and remove burs at the end that would prevent it sliding into the bearing cleanly. The only changes I see today in the basic Duddel bug design is, the advancement in engine horsepower by almost 4 times (!), with over head valve engines. And the addition of a transmission. This improvement resulting in a 35mph top speed carrying an adult, and the machine now being wheelie capable !

Spray the frame. I used a bog-standard rattle can (Hammerite smooth / rust-oleum). Seems to look OK.
