Building my LEGAL stunt 48cc motorized bike! FULL TUTORIAL and ride!
Рет қаралды 131,704
4 жыл бұрынHow to build a motorcycle, driveable with no lisence required! Take it anywhere a bike can go, all with great fuel economy.
Picked up a kit from monsterscooterparts for $138, a bike for $30, and combined them to create a completely legal little motorcycle. With 1.5hp and a 22mph top speed, upgradeable to 30mph with $10. Althought i had to weld some partz of the frame, these modifications can be installed with nuts and modifications. I had to re-tap the rear engine mounts to 3/8 and 5/16, mostly because I ripped it way to hard.

if you ever build any more two stroke motors i highly recommend taking two stroke oil and putting it on your fingers. the metal inside is very well machined and precise. same goes for four stroke engines but use four stroke oil instead. great video man!!!!

That’s a creative outcome sir, nice job ! One observation; the chain tensioner should mount to put the tension to the slack side of the chain run. And another viewer comments that the clutch lever should mount on the left grip Now ride it til the steering head breaks off, or until the cops impound it 😃

When building the motorized BMX do you have to place the fuel tank higher than the bike motor or does it work fine keeping it at the same level? I was just thinking about this to simplify the ascetics of my motorized BMX bike design while keeping it functional.

depends. the kits always come with more chain than you need, most people used to run tensioners but then accidents started to happen where the tensioners came loose and got caught in people's wheels, so now people mostly just shorten the chain and completely remove the tensioner.
