To make the forks, I did the tightest 'S'-bend i was able to with a 3" CLR die in the tube bender. I would guess yours will be the same. Don't worry about the precision on the width too much. There is plenty of room to adjust things later/add spacers etc. Just make sure the fork legs are the same on both sides

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!

Adjust so that the calliper mount is in a position that you can get a good weld against the rear stay. I was hesitating doing a write-up as I was sort-of learning/winging it as I went along since this my first build. It was also the first time bending tubing (which is something I've been meaning to figure out how to do for a long time!). Anyway the bike turned out great and is an absolute hoot to ride so I thought I'd go ahead and do an Instructables.

While minibikes admittedly aren’t the most powerful or high-performance two-wheelers, they are nonetheless are capable of delivering a simple, stripped-down riding experience that maintains much of the thrills of full-size motos. The sensation of the wind in your face and the world speeding past you with nothing separating you from the ground is in no way lost on minibikes. On top of being cheaper to outright buy, minis are also far less expensive to register, maintain, and insure.

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.

The setup with the wheels on live axles etc allowed me the flexibility to use those huge wheels which look great. It added a lot of additional work above sourcing some wheels that have disks already attached to the hub or even drum brakes inside. Here in the UK its hard to buy stuff like that but in U.S / Australia there seem to be many more things like that for sale.

Style: Half-a-century-ago, the vast majority of mini bikes on the market looked a lot like the Honda Z50 or Suzuki Trailhopper, though today — much like the entry-level bike market — minibikes are available in a much wider and more diverse array of styles and genres, from off-road-flavored minis to pint-sized models inspired by naked sportbikes. The motorcycle world’s love for all things retro hasn’t been lost on the mini segment either, and as a result today’s market also includes a handful of contemporary production bikes that are directly modeled after two-wheeled wares of yesteryear. Attach the pump to the tyre valve. The hose head can be switched between Shrader and Presta valves easily.Cut the 1M axle in half and remove burs at the end that would prevent it sliding into the bearing cleanly. Engine Size: Traditionally minibikes were primarily manufactured with micro-displacement engines (usually around 50cc’s), though in a bid to attract adult riders, larger and larger powertrains have been employed. It isn’t uncommon to see production minibikes capable of 50-75mph speeds right out of the box. And, while the majority of minibike engines will be of the air-cooled, eighth-liter, single-cylinder variety, it’s still worth looking into the manufacturer that produced the engine, what kind of internals and systems it uses (such as its cam setup or whether it’s carb’d or fuel injected). And, just like every other facet of the motorcycle, automotive, and transportation industries, electric powertrains are increasingly permeating the minibike space, making EV models worth a look when shopping.

However, " the Dad" should also remember, who helped him build this Duddel Bug. And let the kid ride it too. Unmatched Performance: Experience immediate and precise response as you maneuver through corners and turns with ease.Manufacturer: As you’ll probably glean from this list, minibikes can vary pretty significantly in terms of price, and much of this is owed to the marque badged on the tank. The larger more reputable manufacturers tend to utilize more premium materials and generally offer a higher quality product with superior performance and reliability. Likewise, the major motorcycle manufacturers tend to offer more robust and comprehensive factory warranties, along with better dealer and support networks. You are admittedly paying a bit of a premium for the more reputable name, though the higher MSRP, in this case, does get you an objectively better machine.
