Phatmoto is the affordable all-in-one motorized bike that eliminates the complexities with engine conversion kits.
Our custom designed gas bike can be pedal or engine-powered and travels up to 100 miles at speeds up to 32 MPH on less than 1 gallon of gas. Far from your standard motorized gas-hybrid bike, Phatmoto hides quite a bit of convenient engineering features within traditional bike frame appearance...
With Phatmoto's fully-equipped motorized bicycle, attach the handlebars and front wheel, and with some minimal engine assembly, put in some gas and you're off.
Pedal, Gas Motor, or Hybrid Power
Unlike many DIY conversion kits or electric bikes, Phatmoto was specifically engineered as a dual purpose gas-hybrid bike that makes it significantly easier to ride when pedaling alone and doesn't restrict the engine when under gas power.
Custom Engineered Bike Frame
Unlike many DIY gas bike conversion kits, Phatmoto's bicycle frame is engineered from the ground up to discreetly hide its fuel tank internally, securely bolts its motor to built-in frame mount, and safely encases the drivetrain to avoid accidents.
Easy Pull-Start Handle Engine
Unlike most DIY gas bike conversion kits using two-stroke engines that require vigorous pedaling turn on, Phatmoto opted for a four-stroke engine with a simple pull-start handle and on/off switch for quick and effortless riding.
