Motorized Bicycle Engine Kits – 2-Stroke Performance

Convert a standard bicycle into a gas-powered ride

Our 2-stroke motorized bicycle engine kits give your bike lightweight, high-performance power using a compact gasoline engine that drives the rear wheel through a chain or belt system. Perfect for commuting, cruising, or performance builds, each kit comes complete with everything you need to mount the engine on most standard bicycles, including universal mounting hardware, carburetor, exhaust, fuel tank, throttle, and drivetrain components.

Whether you’re building your first motorized bike or upgrading an existing setup, the kits are ready to get you on the road immediately, with the option to add performance or cosmetic upgrades whenever you like. Choosing the right kit depends on power level, ride feel, and tuning preference.

Engine Displacement (cc)

Engine displacement affects torque and power output. Larger displacement means more speed and force, but also more load on the bike.

• 70cc: Compact performance with higher revving feel
• 80/100cc: Balanced power and torque for all-around performance
• 85cc: High-output, maximum acceleration and speed potential

How to Choose the Right Kit

• Bike compatibility: Fits most steel-framed bikes with adequate clearance
• Power vs control: Higher output provides more speed but adds stress to bike and drivetrain
• Ride feel: Chain drive = direct, responsive power; Belt drive = smooth, quiet operation
• Mechanical comfort: Kits range from simple installs to performance-focused builds
• Upgrade potential: Every kit is fully functional out of the box
