What makes Phatmoto Special
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
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 to turn on, Phatmoto opted for a four-stroke engine with a simple pull-start handle and on/off switch for quick and effortless riding.
Phatmoto's 79cc OHV 4-stroke gas bike engine with automatic clutch allows anyone to travel up to 100 miles at speeds of 25mph on less than a gallon of gas.
Phatmoto is designed to reduce motorized biking accidents from hot engine burns. It is equipped with protective transmission case, engine shield and muffler cage.
Averaging roughly 133 miles per gallon, Phatmoto travels over 100+ miles on 3/4th of a gallon of gas. Operates on regular gas with zero oil/gas mixture needed.
All-New Shimano 7-Speed Gears
Phatmoto 2023 now comes with 7-Speed Shimano gears. You can now maintain a comfortable pedaling speed regardless of the incline or terrain.
Slim 4-stroke gas engine
Phatmoto's motor safely and securely fastens to its custom engineered frame mount to eliminate DIY brackets, loosening from vibration, and conceals wires. At a maximum of 12 inches wide, the engine sits comfortably between your legs. The 2023 model comes with front and rear disc brakes.
Gas engine that's powerful and efficient.
When we set out to design our all-in-one motorized bike with Phatmoto, we wanted it to be powerful, easy to use, and have the option to ride wherever. The 2023 models have an upgraded Jackshaft and Phatmoto Hilliard Heavy Duty #35 Clutch 12 Tooth.

How many miles per gallon?
