Motorized Bicycle is your one stop fabrication shop specializing in custom built motorized bicycle's and accessories which include:
Hand made gas tanks tailored to fit your frame our popular models are the In Frame Gas Tank , Seatpost & Laid Back Seatpost  Gas Tank, 
Sealed Frame Tanks, & Seat Tanks. Along with custom finishes of your choice like Chromed, Anodized, Powder Coated, 
Pin Striped, Decals, or Custom Paint Jobs.  We also accept  Special Gas Tank orders, Have an Idea we can make it!
Exhaust's, Expansion Chambers, Mufflers & Brackets to match. 
Aluminum Intake Manifolds straight or angled depending on clearance, Jetted Carburetors.
We Lathe 6061 grade Aluminum Hubs! Front Dual Disc Brake Bicycle Hubs with German Sealed Bearings rated appropriately. 
Rear Single Disc Brake Hubs Spaced to your Frame width if necessary.
Hi Grade Adjustable and or Vertical  Aluminum Motor Mounts for Any type of Motor Matched to Any type of Frame. Ours wont crack like the $80 Name Brand's Guaranteed! 
2 Stroke - 4 Stroke - Electric ?  Bike, Trike, Unicycle, Rickshaw. 
If you called and said you wanted  to mount a jetpack to grandmothers wheelchair I would moraly advise you against it, but in theory we could do it.
And if you're using stock mounts that come in those overseas kits ... Count Your Lucky Stars!And Brakes Please.That's at the very top of the list Coaster Brakes Brake Ankles! When those 50 cent parts fail the pedals spin as fast as the tire and its not pretty. We have Hydraulic Disc brakes for that.Our main focus is providing a safe high quality product down to the nuts and bolts.
And how fast do you want to go ?
We have friends and customers that have spent upwards of $2,000 for us to fully upgrade Honda's 212cc Predator 4 Stroke Motor.
We can get you very close to triple digits, Its not for everyone and if your not on the track you don't need to be going that fast.
I recommend a basic $200-$300 reliability upgrade on a 4 stroke motor  essentially removing and upgrading the built in obsolescence.
Motor Upgrades : Stroker Motors, Balanced Cranks, Rockers, Big Valve Conversions, Heavy Duty Springs, Cams, Flywheels, Jackshafts And Mechanical Chain Guides.    
Porting... Real Porting ( with degree wheel measurements and micrometers ) Word of advice. Never buy a ported sleeve without the matching bottom end.
It's kinda like wearing a thousand dollar hat ,
with no pants on... at the supermarket. 
Although we Fabricate parts for 2 Stroke Motors 49cc 66cc 80cc etc...  
Custom Builds are 4 Stroke Only . Not because we don't like 2 Stroke's but rather that it turned our fabrication shop into a repair shop.
Feel Free to contact us if you have any questions.
 Ghettobike is a family owned and operated business focused on developing new sustainable products not only to make your ride safe but also to stand out with style . 
With years of experience in mechanical and electrical engineering as well as art and technical direction. We bring our experience to every project. 
After years of working in custom fabrication and design for various industrys, We decided to branch off to form our own fabrication shop.
Having the tools at your disposal not only allows you to broaden your ideas.It allows one to materialize ideas into reality.
Not limited to one specific field we are inventors by nature, finding solutions to the obstacles and challenges that present themselves.
And then it's on to the next. Inspiration sometimes comes from the least likely places so don't exclude something that might seem absolutely impossible.   
Customize Your One Of A kind Build.
