Best Bicycle Motor Kit for Gas and Electric Conversions

#1 · Best Overall

1. IMAYCC 80cc Engine Kit

• Warranty Description: One Year Warranty
• Number Of Speeds: 36
• Frame Material: Metal

Best for: Hands-on gas-kit installer.

Why it ranks #1: The 80cc two-stroke kit fits listed 26–28-inch mountain, cruiser, and road bikes, and specifies a 2.5L tank and one-year warranty.

The IMAYCC kit pairs an 80cc two-stroke engine with a complete conversion set, giving mechanically comfortable riders the core hardware to motorize a compatible bicycle. Its installation notes are unusually concrete: allow about two to four hours for fitting and fine-tuning, and expect to use basic tools and hardware skills.

The listed compatibility covers 26–28-inch mountain, cruiser, and road bikes, making the wheel-size range broad while still requiring a suitable bicycle. A 2.5-litre fuel tank and 415 heavy-duty drive chain are specified, so buyers can assess fuel capacity and the drivetrain parts included in the conversion. Because installation includes fine-tuning and the instructions recommend preparation for first-timers, this kit suits a planned workshop session rather than an effortless bolt-on upgrade.

Skip it if you want a quick, tool-free conversion; consider the BAFANG BBS02B/BBS-HD kit if a mid-drive electric setup suits your bicycle.

This IMAYCC kit fits riders prepared to work through a gasoline-engine installation on a listed 26–28-inch bike. Set aside tools and time for fitting and adjustment; its broad bike-type listing does not remove the need for a compatible frame.

#2 · Best Fit Details

2. H-YEEU 80cc Engine Kit

• Warranty Description: /
• Frame Material: Metal

Best for: Standard-frame gas conversion.

Why it ranks #2: Its 80cc gas engine is listed for 26- or 28-inch bikes, with specific 9–11-inch clearance and 25–29mm frame-tube guidance.

The 80cc two-stroke engine is the defining feature of H-YEEU’s kit, turning a compatible regular bicycle into a motorized ride without switching to an electric hub setup. Its listed speed reaches up to 45 km/h, and the kit is aimed at 26- or 28-inch bikes with a standard V-frame.

The complete engine kit includes the hardware for a conversion, while its heavy-duty metal engine body is specified for durability during use. Compatibility depends on more than wheel size: the frame needs a standard V shape, 9–11 inches of clearance between the bottom bracket and top bar, and tubes measuring 25–29 mm in diameter. The listed fuel consumption is 2.5 litres per 100 km, a useful operating figure for riders weighing fuel use alongside the claimed speed.

Skip it if you have a frame outside the listed V-frame, clearance, or tube-diameter measurements; this kit depends on those dimensions for fit.

Choose this H-YEEU kit if you want a gasoline engine conversion and your 26- or 28-inch bicycle meets its frame measurements. Its listed speed and fuel-use figures may suit longer rides, but frame compatibility is a firm boundary.

#3 · Largest Displacement

3. CUBELLIN 100cc Engine Kit

• Warranty Description: 2 year warranty against manufacturer defects
• Number Of Speeds: 3
• Frame Material: Aluminum, Iron

Best for: High-capacity gasoline conversion.

Why it ranks #3: This 100cc two-stroke kit includes assembly accessories and an English manual, lists a 26-inch wheel size, and states a 440-pound maximum load.

The 100cc, air-cooled two-stroke engine is the defining feature of CUBELLIN’s bicycle conversion kit, with a listed top speed of 48 km/h. Its 36-tooth setup and stated 200 kg maximum load capacity give buyers additional concrete details to consider when evaluating a motorized bicycle conversion.

The kit includes assembly accessories and an English manual, supporting a more complete installation plan than sourcing named parts separately. Its CDI ignition and air-cooling are specified for the single-cylinder, two-stroke engine, while the 36-tooth sprocket identifies a drivetrain detail for setup. The listed fuel economy is 150 miles per gallon, and the 26-inch wheel specification narrows the fit check. Assembly is required, so allow for a hands-on conversion process.

Skip it if you want an electric hub conversion instead of a gasoline engine; the Mahugde 26-inch kit is an electric rear-wheel option.

CUBELLIN suits riders seeking a 100cc gasoline conversion with a manual and assembly accessories, provided their bicycle matches the listed 26-inch format. Account for required assembly and check the drivetrain details before beginning the installation.

4. JAYGOVAN 80cc Engine Kit

Best for: Fuel-conscious gas conversion.

Why it ranks #4: The 80cc two-stroke kit lists 2.1kW output, CDI ignition, and a claimed top speed of 23.61 mph for riders seeking a gas conversion.

A stated fuel-use reference of about 0.53 gallons per 62.14 miles sets the JAYGOVAN 80cc kit apart for riders comparing gasoline consumption. Its two-stroke engine is listed at 2.1 kW and up to 5000 rpm, with a claimed top speed of 23.61 mph for everyday bicycle conversion.

The 80cc engine supplies the gasoline-powered conversion, while CDI ignition is named among the kit’s features. The listed power and rpm figures help characterize the engine, and the stated top speed gives riders a reference for the intended performance. Its fuel-use estimate can help with planning between refueling stops, but it is explicitly a reference value rather than a guaranteed result. The supplied details do not specify a wheel-size or frame-fit range, so compatibility remains an important installation consideration.

Skip it if you need a conversion with a stated wheel-size fit; the Mahugde kit specifies a 26-inch wheel for its electric hub setup.

Consider this JAYGOVAN kit if you want an 80cc gasoline conversion and find its fuel-use reference helpful for ride planning. The listed details do not establish bicycle fit, so resolve compatibility before undertaking installation.

#5 · Mid-Drive Option

5. BAFANG BBS02B Mid-Drive Kit

• Warranty Description: 30 days return,365 days repair or…

Best for: Mid-drive DIY conversion.

Why it ranks #5: This 48V mid-drive kit is listed at 750W and includes a speed sensor, thumb throttle, and chainwheel; battery and LCD are optional.

BAFANG’s BBS02B/BBS-HD mid-drive format places the conversion around the bicycle’s bottom bracket rather than specifying a replacement hub wheel. The kit offers 500W, 750W, and 1000W options, while its listed accessories support a customizable DIY build.

The accessory list names a brake lever, chainwheel, thumb throttle, speed sensor, headlight, and bottom-bracket removal tool, covering several parts of a conversion workflow. Battery and LCD display are optional, allowing buyers to choose those components separately. The listing describes fit for most bikes, but this mid-drive format still makes the bottom bracket central to installation planning. A 48V, 750W specification is also listed, so verify the selected kit configuration when choosing among the stated power options.

Skip it if you want a rear-wheel hub conversion; the Jeaieaiu 26-Inch Electric Bike Conversion Kit is listed as a rear hub setup.

This BAFANG kit suits DIY riders who want a mid-drive conversion with multiple stated power options and named installation accessories. Check bottom-bracket compatibility and account for the optional battery and display when planning the completed build.

6. Mahugde 1000W Hub Kit

• Warranty Description: 1
• Frame Material: Aluminum

Best for: 26-inch electric hub conversion.

Why it ranks #6: The 1000W electric rear-hub kit specifies a 26-inch wheel, aluminum-magnesium-alloy wheel, thumb throttle, and pedal-assist sensor.

A 1000W rear hub motor wheel specified for 26-inch bikes anchors Mahugde’s electric conversion kit, giving riders a clear wheel-size starting point for an upgrade. The listing also names a thumb throttle and pedal-assist sensor, offering two distinct ways to interact with the motorized setup.

The aluminum frame and aluminum-magnesium-alloy wheel materials identify the main construction materials, while the 1000W motor rating describes the kit’s stated power class. A thumb throttle provides a hand-operated control, and the pedal-assist sensor supports assistance while pedaling. The included-components listing names one motor wheel, so buyers should account for the listed scope when planning a conversion. With 26 inches specified, wheel compatibility is more defined than the remaining bicycle-fit details.

Skip it if you need a listing that names a broader accessory set; the Jeaieaiu 26-inch kit specifies a flywheel, PAS sensor, controller bag, and manual.

Mahugde’s kit suits a rider seeking a 26-inch, 1000W rear hub conversion with both throttle and pedal-assist controls. The listed component scope centers on one motor wheel, so plan around that when assessing what your conversion requires.

#7 · Most Complete Hub Set

7. Jeaieaiu 1000W Hub Kit

• Warranty Description: 2 years
• Number Of Speeds: 7
• Frame Material: Iron

Best for: DIY 26-inch commuter conversion.

Why it ranks #7: Its 26-inch, 48V 1000W rear hub kit lists a flywheel, pedal-assist sensor, controller bag, and English manual among included components.

A 48V, 1000W brushless gearless rear hub motor with a stated 440 rpm rating gives the Jeaieaiu kit a clearly defined electric conversion core. It is specified for a 26-inch wheel and lists a PAS sensor, thumb throttle, and controller bag for a do-it-yourself setup.

The included motor wheel and flywheel establish key rear-wheel conversion parts, while the PAS sensor and thumb throttle provide both pedal-assist and hand-control options. A controller bag is also listed, giving the controller a named place within the DIY kit. The 26-inch wheel size and linear-pull brake specification are important bicycle checks before installation. Its seven-speed listing further identifies the stated drivetrain configuration, helping buyers compare their bike setup with the kit details.

Skip it if you have a 20-by-4-inch wheel; the HuaShuani 48V 2000W kit is listed for that wheel format.

Choose Jeaieaiu if you are assembling a DIY electric conversion for a 26-inch bicycle and want both PAS and throttle controls. Check the wheel size and linear-pull brake specification against your bike before starting installation.

8. LTIGOAW 1000W Rear Hub Kit

• Warranty Description: 2 Year

Best for: 26-inch rear-wheel conversion.

Why it ranks #8: This 26-inch 48V 1000W rear-wheel electric conversion kit is a relevant hub-motor alternative, though the supplied specifications give few fit details.

A 26-inch rear-wheel format and 48V, 1000W rating define the LTIGOAW conversion kit, giving buyers two concrete starting points for assessing an electric bicycle upgrade. Its title identifies a rear hub motor wheel, while the listed construction materials include aluminum, iron, copper, magnetic steel, aluminum alloy, and rubber.

The 26-inch specification makes wheel size the first compatibility check for a prospective conversion, and the 48V, 1000W figures identify the stated electrical rating. The rear-wheel arrangement places the motor at the back of the bicycle, while the listed mix of metals and rubber describes the supplied product materials. Because the component listing points buyers to “See details,” confirm the kit contents from the product listing before planning an installation around particular accessories.

Skip it if you want named accessory details before planning installation; the Jeaieaiu 26-inch kit lists its motor wheel, flywheel, PAS sensor, controller bag, and manual.

This LTIGOAW kit may suit a 26-inch-bike owner seeking a rear-wheel conversion with a stated 48V, 1000W rating. The supplied component details are limited, so review the actual kit contents before arranging an installation.

9. Bdujhit 1500W Hub Kit

Best for: Short-distance hub commuting.

Why it ranks #9: The 48V 1500W rear hub includes a PAS sensor and LCD display, but its listed 20-inch wheel makes it a narrower fit than the larger-wheel choices.

The 48V, 1500W rear hub motor is the core of Bdujhit’s 20-inch conversion, with the listing highlighting efficiency above 82% for commuting and short-distance cycling. A pedal-assist sensor and LCD display add a more guided riding workflow than a motor wheel alone.

The PAS sensor supports pedaling assistance, while the LCD display gives riders a screen-based control and information point. Its seven gears provide a stated multi-gear setup, and the brushless, gearless hub motor pairs with a dual-layer rubber wheel. The listing also specifies a controller and a maximum load capacity of about 150 kg. Together, these details make the kit relevant to short trips, though the 20-inch wheel size sets a clear compatibility boundary.

Skip it if you ride a 26-inch bicycle; the Jeaieaiu 26-Inch Electric Bike Conversion Kit is listed for that wheel size.

This Bdujhit kit suits short-distance riders with a compatible 20-inch bicycle who want pedal assistance, a display, and seven gears. Its wheel format is the main fit consideration, so match that dimension before choosing the conversion.

#10

10. HuaShuani 2000W Hub Kit

• Warranty Description: 30 Days

Best for: Display-focused fat-wheel conversion.

Why it ranks #10: This 48V 2000W hub kit targets 20-by-4-inch wheels, a specialized size that limits its suitability for typical bicycle conversion shoppers.

A five-speed hub motor paired with an LCD display gives this HuaShuani kit a particularly informative control setup for a 20-by-4-inch wheel conversion. The screen reports power, speed, mileage, faults, voltage, and current, so riders can monitor several operating details while using its adjustable gears or fixed-speed cruise.

The 48V, 2000W rear hub motor is listed at 550 rpm and a 34 mph no-load speed; that no-load qualifier matters when interpreting the speed figure for real riding. Five adjustable speed gears let riders select among levels, while fixed-speed cruise offers another operating mode. The LCD’s mileage and fault displays support at-a-glance monitoring, and the stated 20-by-4-inch wheel size is a key compatibility boundary before planning installation.

Skip it if you need a conversion for a wheel other than the stated 20-by-4-inch size; the Jeaieaiu 26-inch kit serves a different wheel format.

Pick this HuaShuani kit if your bicycle uses the stated 20-by-4-inch wheel and you value multiple ride modes plus detailed display data. Treat the 34 mph figure as no-load, and check that wheel format before installation.
