Best 2 Stroke Motor Kit For Bicycle: 10 Kits Compared

#1 · Best Overall

1. IMAYCC Bike Motor Kit 80cc Motor Kit

• Weight: 26.4 lb

Best for: Hands-on 26–28-inch bike builders.

Why it ranks #1: Its 80cc kit is specified for 26- to 28-inch mountain, cruiser, and road bikes, and the listing provides installation-time and preparation guidance.

A complete 80cc, 2-stroke engine kit for 26–28-inch bikes gives hands-on builders the core conversion components in one package. Its stated compatibility spans mountain, cruiser, and road bikes, making it a flexible option for riders who want to motorize an existing bicycle rather than start with a different frame.

The 26–28-inch fit range covers several common bicycle styles, so the kit can suit a mountain bike, cruiser, or road bike when the frame is compatible. At 26.4 pounds, the engine assembly is a substantial addition to handle during installation. IMAYCC notes that fitting and fine-tuning take about two to four hours and call for basic hardware skills and tools; its instructions and installation video search guidance can help first-time builders prepare.

Skip it if you want a kit that avoids hands-on fitting; IMAYCC specifies two to four hours of installation and fine-tuning.

This suits a hands-on rider converting a compatible 26–28-inch mountain bike, cruiser, or road bike. Allow time for fitting and tuning, and be prepared to use basic hardware tools rather than treating installation as a tool-free task.

#2 · Best With Speedometer

2. Bikerid 80cc Engine Kit

Best for: Speedometer-seeking 26–28-inch riders.

Why it ranks #2: This 80cc 2-stroke kit fits most 26- to 28-inch bicycles and includes a speedometer, with a stated maximum speed up to 38 km/h.

An included speedometer distinguishes Bikerid’s 80cc, 2-stroke bicycle conversion kit, giving riders a way to monitor speed after converting a compatible bike. The listing targets 26–28-inch bicycles and claims speeds up to 38 km/h, pairing broad stated wheel-size compatibility with a clear performance reference.

Bikerid says the kit fits most 26- to 28-inch bicycles and can reuse an existing bike without major frame modifications. That can make it relevant to owners who want to retain their current bicycle, while still requiring a suitable fit. The included speedometer gives the rider speed information during use, and the claimed maximum of 38 km/h provides a stated benchmark. The listing also identifies high-torque output and hill climbing as intended operating benefits.

Skip it if you need published frame-clearance measurements before choosing; Borutools specifies a 9–11-inch clearance requirement.

This fits riders seeking a speedometer-equipped 80cc conversion for a 26–28-inch bicycle, especially when keeping the existing bike matters. Its listing does not give clearance measurements, so buyers needing precise frame criteria may prefer a kit with them stated.

#3 · Best Stated Fuel Use

3. JAYGOVAN 80cc Engine Kit

Best for: Fuel-use-conscious 80cc commuters.

Why it ranks #3: The 80cc kit lists 2.1 kW output, speeds up to 23.61 mph, and reference fuel use of about 0.53 gallons per 62.14 miles.

JAYGOVAN lists reference fuel use of about 0.53 gallons per 62.14 miles, giving efficiency-minded riders a stated consumption figure for its 80cc, 2-stroke conversion kit. Its 2.58-horsepower output and claimed top speed of 23.61 mph provide additional performance figures for planning an everyday bicycle conversion.

The listed 2.1 kW (2.58 hp) output and top speed of 23.61 mph give builders concrete performance claims to weigh against the reference fuel-use figure. That consumption estimate is specified as approximately 0.53 gallons per 62.14 miles, so it offers a comparison point rather than a guaranteed result for every ride. The listing also names CDI ignition and easy starting, features relevant to engine operation, though it does not provide detailed bicycle fit measurements in the supplied facts.

Skip it if you need a stated wheel-size fit range; IMAYCC lists compatibility with 26–28-inch bicycles.

This is for riders weighing stated output and reference fuel consumption when selecting an 80cc conversion for everyday use. Check the bicycle-fit details before proceeding, since the supplied specifications do not identify a wheel-size range.

#4

4. Borutools 80cc Engine Kit

• Weight: 24.2 lb

Best for: Clearance-checking commuter builders.

Why it ranks #4: Its 80cc kit is listed for 26- and 28-inch V-frame bikes and specifies 9–11 inches of clearance between the bottom bracket and top bar.

A stated top speed of up to 38 km/h gives Borutools’ 80cc, 2-stroke kit a defined performance target for riders converting a bicycle for commuting or leisure. Its listed compatibility covers most 26- and 28-inch V-frame bikes, while specified frame clearance helps buyers assess fit before beginning a conversion.

The V-frame fit guidance covers mountain, cruiser, chopper, and road models, but the frame must also provide 9–11 inches between the bottom bracket and top bar. That measurement makes a preliminary fit check important before installation. Borutools also specifies frame-tube diameter limits in its listing, so builders can compare their bicycle against the stated requirements. The claimed speed of up to 38 km/h gives the conversion a concrete performance reference for everyday and recreational riding.

Skip it if you cannot meet the stated V-frame clearance; IMAYCC’s 26–28-inch kit lists bike styles without that clearance figure.

This is for a builder with a compatible V-frame bicycle who wants a stated speed target for commuting or leisure. Measure the required clearance and check the frame-tube limits before committing to the conversion.

#5 · Best Tunable Carburetor

5. YUNLAIGOTOP 100cc Engine Kit

Best for: Tunable-carburetor 100cc builders.

Why it ranks #5: The 100cc kit lists a tunable carburetor with adjustable jets and screws, a 44-tooth sprocket, upgraded CDI, and a one-year defect warranty.

A carburetor with a re-jettable main jet and adjustable idle controls makes this YUNLAIGOTOP 100cc kit the option for builders who want tuning points. Its listing also names a red speed carburetor, upgraded CDI, air cooling, and a 44-tooth sprocket as parts of the conversion setup.

The carburetor’s re-jettable main jet, pilot jet, and idle RPM and air screws give a builder several named adjustment points for tuning. A handlebar choke lever puts that control within reach during operation. The kit also lists an upgraded CDI and 44-tooth sprocket among its included upgrade components, while air cooling is specified for the engine. Its stated maximum speed is 48 km/h, offering a performance reference alongside these setup features.

Skip it if you want a 36-tooth sprocket; Tipyoumall lists that tooth count on its 110cc kit.

This suits a mechanically engaged builder who values carburetor adjustment points and a 44-tooth sprocket in a 100cc conversion. The stated 48 km/h maximum is a useful reference, but assess bicycle compatibility before installation.

#6 · Best Warranty

6. CUBELLIN 100cc Engine Kit

• Weight: 6.8 kg

Best for: 36-tooth 100cc conversion buyers.

Why it ranks #6: This 100cc kit includes an English manual and assembly accessories, lists a 36-tooth sprocket and 48 km/h top speed, and states a two-year defect warranty.

A 36-tooth sprocket paired with a stated top speed of 48 km/h gives CUBELLIN’s 100cc, 2-stroke conversion kit two concrete specifications for a bicycle build. The listing includes assembly accessories and an English manual, supporting buyers who want kit components and written guidance together.

The 36-tooth sprocket identifies the supplied drivetrain component, while the claimed 48 km/h top speed gives a stated performance reference. CUBELLIN lists a 440-pound maximum load, which helps buyers consider the stated capacity alongside their planned use. The included assembly accessories and English manual can support the installation workflow, though assembly is required. The listing also specifies a single-cylinder, air-cooled, 2-stroke engine with CDI ignition for builders comparing engine configuration.

Skip it if you want a stated 110cc displacement; Tipyoumall lists a 110cc kit with a 36-tooth sprocket.

This suits a buyer seeking a 100cc conversion with a 36-tooth sprocket, written assembly guidance, and a stated load limit. Allow for assembly, and consider the 48 km/h claim as a listing specification rather than a fit guarantee.

#7

7. Ubnffsv 100cc Engine Kit

Best for: Longer-range 100cc kit shoppers.

Why it ranks #7: The 100cc kit lists a 0.53-gallon fuel tank, a 36-tooth sprocket, and fit for most 26- or 28-inch bikes.

A 0.53-gallon fuel tank gives Ubnffsv’s 100cc, 2-stroke kit a stated capacity for riders planning longer intervals between refueling. Its listing also names a 36-tooth sprocket, CDI ignition, and fit for most 26- or 28-inch bikes, giving builders several practical conversion details to evaluate.

The 0.53-gallon tank and stated fuel consumption of around 0.66 gallons per 100 km give riders two figures for considering refueling needs; actual range depends on use, so the listed values are planning references. The 36-tooth sprocket and CDI ignition identify drivetrain and ignition components. Ubnffsv also states a maximum load of 440 pounds and fit for most 26- or 28-inch bikes, helping buyers assess capacity and bicycle size together.

Skip it if you prioritize a lower stated fuel-use figure; Tipyoumall claims 150 miles per gallon for its 110cc kit.

This suits riders prioritizing a larger stated tank and a 100cc conversion for a compatible 26- or 28-inch bike. Use the listed fuel-consumption figure as a planning reference, and keep the 440-pound maximum load in view.

#8

8. Tipyoumall 110cc Engine Kit

• Weight: 11 kg

Best for: 36-tooth sprocket conversion planners.

Why it ranks #8: This 110cc kit is listed for 26- to 28-inch bikes and specifies a 36-tooth sprocket, tool kit, and 150 miles per gallon claim.

A 36-tooth sprocket is a specific drivetrain detail on Tipyoumall’s 110cc, 2-stroke bicycle engine kit, giving conversion planners a concrete component to consider. The listing targets 26–28-inch bicycles and states fuel consumption of 150 miles per gallon, with a break-in oil-mixing instruction for initial operation.

The 36-tooth sprocket and stated 26–28-inch fit give buyers two useful details to check against their bicycle and conversion plan. Tipyoumall claims 150 miles per gallon, a fuel-use figure that can help riders compare listed operating expectations, while specifying eight ounces of 2-stroke oil per gallon of gas during the break-in period. The listing also says four bolts attach the engine to the frame, making the mounting approach another practical installation detail.

Skip it if you need a stated regular-use oil mixture; Mahugde lists a fuel-tank capacity but does not replace that specific detail.

This suits a builder seeking a 110cc kit with a specified sprocket and a stated break-in mixture. Check the bicycle’s fit and plan for the listed oil requirement during break-in before starting the conversion.

#9

9. Tiozuiu 110cc Engine Kit

• Weight: 24.7 lb

Best for: 110cc short-trip conversion builders.

Why it ranks #9: Its 110cc 2-stroke kit is listed for 26- or 28-inch bikes and includes air cooling and a CDI system, though detailed fit information is limited.

A 110cc engine with a stated speed of 6,000 rpm gives Tiozuiu’s conversion kit a larger-displacement alternative for riders outfitting a 26- or 28-inch bicycle. The package is described as complete, and its air-cooling and CDI system identify key engine features for short trips and commuting.

The stated 26- or 28-inch fit makes wheel size a useful first screening point, while the complete-kit description indicates that parts and accessories for conversion are included. Air cooling and a CDI system are named engine features, giving buyers specific system details to consider when planning the build. Tiozuiu associates the kit with commuting and short trips; the 6,000-rpm figure is a stated operating specification, not a road-speed claim, so it should not be read as one.

Skip it if you need a listed road-speed target; Bikerid states a maximum of 38 km/h for its 80cc kit.

This suits a builder seeking a 110cc, air-cooled conversion for a 26- or 28-inch bike and short-trip use. Consider that the listing specifies rpm but not road speed when comparing expected riding performance.

#10

10. Mahugde 110cc Engine Kit

Best for: 110cc CDI-equipped DIY builders.

Why it ranks #10: The 110cc kit lists air cooling, CDI ignition, 3 kW maximum power, and a 2-liter tank, but gives less specific frame-fit detail.

A stated 3 kW maximum power at 6,000 rpm gives Mahugde’s 110cc kit a concrete engine-output specification for DIY bicycle conversion. It combines an air-cooled, single-cylinder, 2-stroke design with CDI ignition and pedal starting, and is listed for suitable 26- or 28-inch V-frame bikes.

The V-frame requirement and need for ample triangular space make frame shape a key fit consideration, while the listed mountain, road, and cruiser categories help narrow the candidate bicycles. A 2-liter fuel tank provides a stated capacity for trip planning, and the pedal-start mode identifies how the engine is started. Air cooling, CDI ignition, and a 16.4:1 total transmission ratio add useful mechanical specifications for builders comparing the conversion’s setup.

Skip it if you lack a suitable V-frame; CUBELLIN lists a 100cc kit with a 36-tooth sprocket instead of a frame-shape requirement.

This is for DIY builders seeking a 110cc kit with stated output, pedal starting, and a 2-liter tank. Confirm that the bicycle has a V-shaped frame and ample triangular space before planning the installation.
