A strong gas bike motor kit pairs a clearly stated engine and ignition setup with compatibility details that match your bicycle; it suits riders ready to convert a suitable bike and handle installation. This roundup compares ten 2-stroke kits, mostly listed for 26- to 28-inch bikes, with engine sizes from 80cc to 110cc. The JAYGOVAN 110cc kit leads for its stated 34.15 mph top speed, CDI ignition, foot-pedal starting, and listed hardware.
Other options stand out for frame measurements, fuel-use claims, or a 100cc configuration. Treat advertised speed and fuel figures as manufacturer claims, not guarantees: results can depend on the bicycle, setup, rider, and conditions.
Before choosing, verify frame clearance, mounting fit, and local rules for motorized bicycles.
The JAYGOVAN 110cc Engine Kit is the strongest all-around pick in this group because it combines a stated 34.15 mph top speed and 6000 rpm maximum with CDI ignition and foot-pedal starting. Its listed kit components include a carburetor assembly, exhaust muffler, fuel tank, and clutch handle. The product information also says it fits 26-inch bikes and describes instructions and hardware, but confirm your particular frame and installation needs before buying.

Detailed Reviews: Best Gas Bike Motor Kit
#1 · Best Overall
1. JAYGOVAN 110cc Kit
Best for: Quieter pedal-start conversions.
Why it ranks #1: Its stated 34.15 mph top speed, CDI ignition, foot-pedal starting, and listed fuel tank and exhaust make this a well-detailed 110cc conversion option.
JAYGOVAN lists a 75 dB operating-noise figure and pedal starting for its 110cc kit, giving riders two concrete details about starting and sound. The product also states a top speed of 34.15 mph and includes a CDI ignition system for 26- or 28-inch bicycle conversions.
The foot-pedal start means riders begin by pedaling, while the CDI electronic ignition is part of that starting system. JAYGOVAN lists operation at approximately 75 dB, a specific noise figure relevant to outdoor use, and a top speed of 34.15 mph. The kit includes a 415 heavy-duty chain, a 2-litre fuel tank, and conversion components such as a carburetor assembly and exhaust muffler. Its listed fit covers 26- and 28-inch bikes.
- 110cc engine with a stated top speed of 34.15 mph
- CDI electronic ignition and foot-pedal start
- Approximately 75 dB listed operating noise
- 2-litre fuel tank and 415 heavy-duty chain
- Starting requires pedaling; the listing specifies foot-pedal start.
Skip it if you want a listed 150-mpg fuel figure and four-bolt engine attachment; Tipyoumall's 110cc kit specifies both.
This JAYGOVAN kit suits riders converting a 26- or 28-inch bicycle who value a stated noise figure and pedal starting. The listed top speed is a specification, while the required starting method remains a practical boundary.

2. H-YEEU 80cc Kit
Best for: Measured V-frame compatibility.
Why it ranks #2: It specifies 26- or 28-inch bikes, 9–11 inches of frame clearance, and 25–29 mm frame tubes, giving buyers concrete compatibility checks.
H-YEEU specifies 26- or 28-inch wheels, a standard V-frame, 9–11 inches of frame clearance, and 25–29 mm frame tubes. Those concrete fit details help owners screen a bicycle before planning an 80cc gasoline conversion, rather than relying on wheel size alone.
The stated frame dimensions give buyers a practical pre-installation check: measure the clearance between the bottom bracket and top bar, then check tube diameter alongside wheel size. The kit is an 80cc two-stroke set with a heavy-duty metal engine body, and its description cites fuel consumption of 2.5 litres per 100 km. That combination suits riders who can verify the frame measurements and want a specified economy figure, though the supplied speed descriptions differ.
- Fit guidance covers most 26- and 28-inch bikes with standard V-frames
- Specifies 9–11 inches of frame clearance
- Specifies 25–29 mm frame-tube diameter
- Heavy-duty metal engine body and stated 2.5 L/100 km consumption
- The listing gives different maximum-speed figures: 30 km/h in one feature and 45 km/h in another.
Skip it if you need one consistent listed maximum-speed figure; IMAYCC's 80cc kit instead specifies installation time and compatible bike types.
This H-YEEU set fits buyers whose 26- or 28-inch V-frame bicycle meets its stated clearance and tube dimensions. Its frame guidance is useful, but the conflicting speed figures make a precise pace expectation difficult.

3. YUNLAIGOTOP 100cc Kit
Best for: Tunable-carb 100cc conversion.
Why it ranks #3: The kit lists a tunable carburetor with adjustable jets and screws, upgraded CDI, and a stated maximum speed of 48 km/h.
YUNLAIGOTOP's 100cc kit pairs a tunable carburetor with a handlebar choke lever, giving mechanically inclined riders control over setup and carburetor adjustments. The listing also specifies a 44-tooth sprocket and upgraded CDI, making these components central considerations when planning a 26–28-inch bicycle conversion.
The carburetor's main jet can be re-jetted, and its pilot jet, copper oil needle, idle-RPM screw, and idle-air screw provide named adjustment points. That setup detail is useful to owners prepared to tune the engine rather than treating carburetion as fixed. The included 44-tooth sprocket and upgraded CDI round out the listed conversion components. Specifications give 1.9 kW at 5,500 rpm, air cooling, and a maximum speed of 48 km/h for the 100cc engine.
- Tunable carburetor with re-jettable main jet
- Handlebar choke lever and named idle adjustments
- 44-tooth sprocket and upgraded CDI included
- Listed 1.9 kW output and 48 km/h maximum speed
- The engine uses kick starting, which requires a physical kick-start action.
Skip it if you prefer foot-pedal starting and a 2 L tank with a stated new-engine mix; Wmpusll's 110cc kit lists both.
This YUNLAIGOTOP kit is for 26–28-inch bike owners comfortable adjusting a carburetor and using kick starting. Its tunable jets and screws offer setup points, but the listed starting method is an important fit consideration.

4. JAYGOVAN 80cc Kit
Best for: Efficient 80cc daily rides.
Why it ranks #4: This 80cc option states 2.58 hp, up to 23.61 mph, CDI ignition, and reference fuel use of 0.53 gallons per 62.14 miles.
The JAYGOVAN 80cc kit pairs 2.58 hp with a stated top speed of 23.61 mph, giving everyday bicycle rides a specific power and speed upgrade. Its listed fuel-use figure is about 0.53 gallons per 62.14 miles, making fuel efficiency part of the appeal for riders planning regular trips.
CDI ignition accompanies the 80cc two-stroke engine, while output is listed at 2.58 hp and speed at up to 23.61 mph. Together, those figures describe a conversion aimed at adding powered pace to ordinary rides. The fuel-use estimate—about 0.53 gallons per 62.14 miles—can help riders think through stops on longer outings, but it is identified as a reference value, not a promised result. The supplied information does not specify frame-fit measurements.
- 80cc two-stroke engine kit
- 2.58 hp output
- Listed top speed of 23.61 mph
- CDI ignition and a stated fuel-use reference
- The fuel-use figure is explicitly a reference value, so it is not a guaranteed range estimate.
Skip it if you need stated frame-clearance measurements before choosing; H-YEEU's 80cc kit lists specific frame dimensions and tube diameters.
For riders seeking an 80cc conversion with a stated 23.61 mph top speed and CDI ignition, this JAYGOVAN kit merits consideration. Its listed fuel-use figure is only a reference, and frame-fit dimensions are not supplied.

5. Wmpusll 110cc Kit
Best for: Pedal-start 110cc commuters.
Why it ranks #5: Its listed 3 kW maximum power at 6000 rpm, 34 mph top speed, CDI ignition, and foot-pedal start provide useful performance details.
Wmpusll specifies a 110cc engine with 3 kW maximum power at 6,000 rpm and a stated top speed of 55 km/h. Its foot-pedal start and CDI ignition make the starting workflow clear for riders considering a motorized bicycle for daily commuting.
The foot-pedal starting system fires the engine without an electric starter, giving riders a straightforward, pedal-based start routine. CDI ignition is listed alongside the 110cc, two-stroke single-cylinder engine. A 2-litre fuel tank and recommended 16:1 gasoline-to-oil ratio for new engines provide concrete preparation details before riding. The stated 3 kW maximum power, 6,000-rpm figure, and 55 km/h top speed describe the performance claims buyers can weigh for a 26- or 28-inch bike.
- 110cc two-stroke single-cylinder engine
- 3 kW maximum power at 6,000 rpm
- Listed top speed of 55 km/h
- Foot-pedal start, CDI ignition, and 2-litre tank
- New engines call for a recommended 16:1 gasoline-to-oil mix.
Skip it if you need a stated 36-tooth sprocket and 150-mpg figure; Tipyoumall's 110cc kit lists those specifics.
Wmpusll fits riders seeking a 110cc commuter conversion with foot-pedal starting and clearly stated performance figures. New-engine fuel preparation requires the listed 16:1 mix, so include that step in your operating routine.

6. Mahugde 110cc Kit
Best for: 110cc V-frame commuters.
Why it ranks #6: The 110cc kit specifies 3 kW at 6000 rpm, CDI ignition, air cooling, a 2 L tank, and foot-pedal starting.
Mahugde combines a 110cc engine with a 2-litre fuel tank and CDI ignition, giving riders a defined set of conversion specifications for commutes and short journeys. Its compatibility notes focus on V-shaped frames with ample triangular space, covering mountain, road, and cruiser bicycles.
The listed 3 kW maximum power at 6,000 rpm describes the engine output, while the 2-litre tank establishes its stated fuel capacity. CDI ignition and foot-pedal starting clarify the system and starting method buyers will use. Compatibility is framed around V-shaped bicycle frames with ample triangular space, rather than wheel size alone, so shoppers should assess that frame layout. The 2-stroke, air-cooled, single-cylinder configuration further identifies the engine type for owners comparing conversion setups.
- 110cc, 2-stroke, air-cooled single-cylinder engine
- 3 kW maximum power at 6,000 rpm
- 2-litre fuel tank and CDI ignition
- Compatibility notes cover V-frame mountain, road, and cruiser bikes
- Starting is by foot pedal, rather than a listed electric-start system.
Skip it if you need an explicitly listed 26–28-inch fit range; Wmpusll's 110cc kit names those wheel sizes.
Mahugde suits a rider with a V-frame bicycle and enough triangular frame space who wants a 110cc kit with specified tank capacity and pedal starting. Check the frame layout against its stated compatibility guidance.

7. Tiozuiu 110cc Kit
Best for: 110cc short-trip conversion.
Why it ranks #7: This 110cc conversion kit lists air cooling and CDI, with a stated operating speed reaching 6000 rpm for buyers seeking a larger engine.
Tiozuiu's 110cc kit lists operation up to 6,000 rpm, giving a bicycle conversion a clearly stated engine-speed figure for commutes and short trips. The title identifies air cooling and a CDI system, while the complete-kit description frames it as a single-set conversion option.
The 6,000-rpm figure gives riders a concrete specification to weigh for everyday commuting and short outings. Air cooling and a CDI system are named in the product title, and the listing describes a complete kit with parts and accessories for conversion. It specifies compatibility with 26- or 28-inch bikes, which narrows the relevant bicycle sizes. At 24.7 pounds, the kit's listed weight is also worth considering when handling and mounting the engine during installation.
- 110cc two-stroke conversion kit
- Listed operating speed up to 6,000 rpm
- Air cooling and CDI system named in the title
- Stated fit for 26- or 28-inch bikes
- The kit weighs 24.7 pounds, a substantial assembly to handle during installation.

8. Tipyoumall 110cc Kit
Best for: Fuel-economy-minded builders.
Why it ranks #8: Its 110cc kit lists a 36-tooth sprocket, a 396-pound maximum weight recommendation, and a fuel-efficiency claim of 150 miles per gallon.
Tipyoumall states 150 miles per gallon for its 110cc kit and specifies an 8-ounce two-stroke-oil mix per gallon of gas during break-in. Those fuel and setup details give conversion builders concrete operating information, alongside a 36-tooth sprocket and a four-bolt engine attachment.
The stated 150-mpg figure gives buyers a fuel-economy claim to consider, while the break-in instruction makes the initial fuel preparation specific: 8 ounces of two-stroke oil per gallon of gas. The 36-tooth sprocket identifies a drivetrain component included in the listing, and four bolts attach the engine to the bicycle frame. The kit is described for 26–28-inch bikes, with a listed maximum weight recommendation of 396 pounds, helping buyers assess basic fit and load considerations.
- 110cc two-stroke engine kit
- Listed fuel economy of 150 mpg
- 36-tooth sprocket
- Four-bolt engine attachment and stated 26–28-inch fit
- Break-in requires mixing 8 ounces of two-stroke oil per gallon of gas.

9. Ubnffsv 100cc Kit
Best for: Longer-ride tank capacity.
Why it ranks #9: The 100cc kit lists a 0.53-gallon tank and 440-pound maximum load, but the supplied information offers fewer installation and fit measurements.
Ubnffsv lists a 0.53-gallon fuel tank and consumption of about 0.66 gallon per 100 km, giving riders concrete figures for thinking about refueling on longer rides. Its 100cc, two-stroke kit also includes a 36-tooth sprocket and is described for most 26- or 28-inch bikes.
The tank capacity and stated fuel consumption help set expectations for trip planning, although actual distance depends on use and the listing gives no guaranteed range. A 36-tooth sprocket is specified, adding a concrete drivetrain component to consider during conversion. The product also lists a maximum load of 440 pounds, a relevant limit for weighing the bicycle and rider setup. Its 100cc engine is air-cooled and uses CDI ignition according to the product description.
- 0.53-gallon fuel tank
- Stated fuel consumption of about 0.66 gallon per 100 km
- 36-tooth sprocket
- Listed maximum load of 440 pounds
- The listed consumption rate is about 0.66 gallon per 100 km, a figure to weigh for frequent long rides.
Skip it if you want a stated 150-mpg figure and 36-tooth sprocket; Tipyoumall's 110cc kit lists both.
This Ubnffsv kit suits riders considering longer outings who value a stated tank capacity and load limit. Treat its consumption figure as a planning reference, and check that the bicycle setup stays within the listed 440-pound maximum load.

10. IMAYCC 80cc Kit
Best for: Hands-on 80cc installation.
Why it ranks #10: This complete 80cc kit is listed for 26- to 28-inch bikes and weighs 26.4 pounds; its instructions call for mechanical skills and tuning.
IMAYCC gives a 2–4-hour installation and fine-tuning estimate and calls for basic hardware skills and tools. That unusually practical setup guidance helps first-time conversion shoppers judge the work involved before choosing its 80cc, two-stroke engine kit for a compatible bicycle.
The stated fit covers 26–28-inch mountain, cruiser, and road bikes, giving those owners a clear starting point for assessing the conversion. Installation is estimated at 2–4 hours, including fine-tuning, and the listing advises reading the instructions; it also points inexperienced installers to an IMAYCC video guide. At 26.4 pounds, the kit is a substantial component to handle during setup. Its 2.1 kW specification identifies the engine's listed wattage.
- 80cc two-stroke single-cylinder engine kit
- Fits listed 26–28-inch mountain, cruiser, and road bikes
- Installation and fine-tuning estimated at 2–4 hours
- 2.1 kW listed wattage
- Installation calls for basic hardware skills and tools, plus 2–4 hours for setup and fine-tuning.
Skip it if you want frame-clearance and tube-diameter measurements stated upfront; H-YEEU's 80cc kit lists both dimensions.
Choose this IMAYCC kit if you own a listed 26–28-inch bike and are prepared for hands-on fitting and tuning. The time estimate and skill requirement make it less suited to buyers seeking a simple, tool-free conversion.

View on AmazonCheck frame fit before ordering
A wheel-size match does not establish that an engine will fit your bicycle; measure the frame and mounting space before choosing a kit. H-YEEU gives the clearest supplied frame criteria: a standard V-frame, 9–11 inches of clearance between the bottom bracket and top bar, and frame tubes 25–29 mm in diameter. Several other listings say they fit 26- or 28-inch bikes, but that alone does not confirm tube shape, clearance, or mounting compatibility on an individual bicycle.
Tipyoumall describes four bolts attaching its engine to the frame, while IMAYCC advises that installation takes basic hardware skills and roughly two to four hours of installation and fine-tuning. Treat those details as prompts to inspect your own bike, not proof of universal fit.
If measurements or mounting points differ, pause and seek confirmation before buying or modifying the frame.
Plan for setup, tuning, and safe operation
A gas engine conversion requires more than bolting on a motor: installation, adjustment, and a compatible bicycle all matter. The IMAYCC listing explicitly anticipates two to four hours of installation and fine-tuning and recommends instructions for first-time installers. YUNLAIGOTOP provides an unusually adjustable carburetor, including main and pilot jets and idle adjustments, which can offer tuning flexibility but also means settings may need attention.
Fuel-mix directions are not uniform across these listings: Mahugde gives a 16:1 recommendation for new engines, while Tipyoumall specifies 8 ounces of two-stroke oil per gallon during break-in. Follow the selected kit’s own instructions rather than transferring a ratio from another product.
The supplied data does not establish legal classification, registration, road access, or required protective equipment; check local rules and use appropriate safety precautions before riding.
How to Choose a Gas Bike Motor Kit
Engine size and stated performance
Choose an engine size and performance claim that suit your intended riding, while treating advertised figures as claims rather than guaranteed results. The listings range from 80cc to 110cc: JAYGOVAN’s 80cc kit states 2.58 hp and up to 23.61 mph, while its 110cc kit claims a 34.15 mph top speed. Wmpusll lists 3 kW maximum power at 6000 rpm and a 34 mph top speed; YUNLAIGOTOP lists a 48 km/h maximum speed for its 100cc kit.
These figures are not directly comparable tests. An 80cc option may suit a buyer prioritizing a smaller stated engine, while buyers seeking the higher claimed speed may prefer a better-documented 110cc listing.
Bicycle and frame compatibility
Check frame dimensions and mounting space rather than relying on wheel size alone. H-YEEU says its kit fits many 26- or 28-inch bikes with a standard V-frame, 9–11 inches of clearance between the bottom bracket and top bar, and 25–29 mm frame tubes. Other products, including JAYGOVAN’s 110cc kit and IMAYCC’s 80cc kit, list compatibility with 26- to 28-inch bikes, but do not supply the same tube measurements.
Tipyoumall lists a 396-pound maximum weight recommendation, while Ubnffsv states a 440-pound maximum load; these are product claims, not a substitute for checking the bicycle’s own limits. Buyers with an exact frame match can use the dimensional guidance; those with unusual frames should confirm fit first.
Starting, ignition, and included setup
Look for a starting method and kit contents that suit your installation plans and mechanical confidence. JAYGOVAN’s 110cc listing specifies CDI electronic ignition and foot-pedal starting, and names a fuel tank, exhaust muffler, carburetor assembly, and clutch handle among the included components. Wmpusll also specifies CDI and foot-pedal starting.
YUNLAIGOTOP includes an upgraded CDI and a tunable carburetor with adjustable jets and idle controls, which may appeal to someone prepared to tune the engine. IMAYCC estimates two to four hours for installation and fine-tuning and calls for basic hardware skills.
Buyers who want clearly enumerated components can start with JAYGOVAN; those comfortable adjusting a carburetor may value YUNLAIGOTOP’s specified controls.
Which Gas Bike Motor Kit Should You Choose?
For a broadly specified 110cc conversion with named starting and ignition features, choose the JAYGOVAN 110cc Kit: it lists a 34.15 mph top speed, CDI ignition, foot-pedal starting, and several included components. If frame measurements are your main concern, the H-YEEU 80cc Kit is the clearest match-checking option, with stated tube diameter and clearance ranges. Choose the YUNLAIGOTOP 100cc Kit if a tunable carburetor and a listed 48 km/h maximum speed matter more.
Riders comparing smaller engine sizes can consider the JAYGOVAN 80cc Kit, which gives a specific power and fuel-use claim. For any option, verify frame compatibility, follow that kit’s installation and fuel instructions, and check local requirements before riding.
Frequently Asked Questions
What frame dimensions and clearances should I measure before buying a gas bike motor kit?
Measure your frame tube diameters and the available mounting space, then check clearance around the engine area and nearby bicycle components. Compare those measurements with the kit’s stated fit ranges and instructions. The H-YEEU 80cc Kit is the clearest match-checking option in this group because it lists tube diameter and clearance ranges.
What tools and mechanical skills are needed to install and tune a two-stroke bicycle engine kit?
Plan on basic mechanical ability and tools appropriate to the kit’s installation steps, but check its instructions for the exact requirements. Mounting, connecting, and tuning components may require careful adjustment. The JAYGOVAN 110cc Kit is described as including instructions and hardware; confirm what your selected kit provides before starting.
What local rules, registration requirements, and safety equipment apply to a motorized bicycle?
Requirements depend on where you ride, so check local rules before buying or operating a conversion. Verify whether registration, licensing, equipment, or operating restrictions apply to your motorized bicycle. Follow the kit’s installation and fuel instructions, and use safety equipment required by your location; do not assume rules are the same everywhere.
Which kit features are useful when comparing engine options?
Compare the stated engine size, ignition and starting features, fit information, and any listed performance claims. The JAYGOVAN 110cc Kit lists CDI ignition, foot-pedal starting, and a 34.15 mph top speed. The YUNLAIGOTOP 100cc Kit may suit shoppers prioritizing a tunable carburetor and its listed 48 km/h maximum speed.
How can I confirm what components come with a kit?
Check the exact product information and instructions for the kit you plan to buy, since listed components can differ. The JAYGOVAN 110cc Kit names a carburetor assembly, exhaust muffler, fuel tank, and clutch handle among its components. Confirm the contents directly for other kits rather than assuming they include the same parts.
Final Words
For the strongest all-around choice in this group, consider the JAYGOVAN 110cc Kit: it lists a 34.15 mph top speed, CDI ignition, foot-pedal starting, and several included components. If fit measurements are your priority, compare your frame against the H-YEEU 80cc Kit’s stated tube and clearance ranges. Check each kit’s instructions, contents, and fuel guidance, confirm frame compatibility, and verify local requirements before riding.
