Best Bicycle Motor Kit for Electric and Gas Conversions

#1 · Best Overall

1. BAFANG BBS02B/BBS-HD Mid-Drive Kit

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

Best for: DIY mid-drive builders.

Why it ranks #1: Offers 500W, 750W, or 1000W configurations and lists a brake lever, chainwheel, throttle, and speed sensor; battery and display are optional.

A BAFANG mid-drive offered in 500W, 750W, and 1000W versions gives DIY builders a choice of stated motor output for a bicycle conversion. The kit lists a thumb throttle, brake lever, chainwheel, speed sensor, headlight, and bottom-bracket removal tool, plus optional battery and LCD selections.

The mid-drive format and included bottom-bracket removal tool make this a parts-focused option for someone prepared to work at the crank area. A speed sensor, brake lever, and thumb throttle are listed alongside the chainwheel, giving the conversion its core control and sensing components. The 48V specification and 750W wattage apply to the listed configuration; the title also names 500W and 1000W versions. Battery and LCD are optional, so plan around the selected kit contents.

Skip it if you want a rear-wheel conversion instead of a mid-drive; the BAFANG RM G020.500.DC kit is a rear-hub option.

Choose this BAFANG kit if you want a mid-drive conversion and value having several core controls and a removal tool listed together. Check the selected wattage and optional battery and display before planning the build.

#2 · Best BAFANG Hub

2. BAFANG 48V Rear Hub Kit

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

Best for: Multi-wheel-size hub converters.

Why it ranks #2: A 48V rear-hub option from BAFANG, with stated 500W or 750W versions and compatibility across wheel sizes from 20 to 29 inches.

BAFANG lists this 48V rear-hub kit for wheel sizes from 20 inches through 29 inches, including 700C, giving converters a broad range of wheel formats to consider. The title identifies 500W and 750W versions, while the model is RM G020.500.DC.

The rear-hub layout makes the wheel the focus of the conversion, and the listed wheel-size range covers 20, 26, 27.5, 700C, 28, and 29 inches. That spread gives owners of several common wheel formats a candidate without shifting to a mid-drive setup. The kit is specified at 48V, with 500W and 750W options named in the title. An LCD display is optional, so it should not be assumed as part of every selection.

Skip it if you want a mid-drive setup or a display included as standard; the BAFANG BBS02B/BBS-HD listing also specifies a mid-drive format.

Consider this BAFANG kit if your bicycle uses one of its listed wheel sizes and you want a rear-hub conversion. Confirm the selected power and display options against your build plan before ordering.

#3 · Best 1500W Hub

3. Bdujhit 1500W Rear Hub Kit

Best for: 20-inch hub commuters.

Why it ranks #3: Combines a 48V 1500W rear hub with a PAS sensor and LCD display, making its listed components useful for an electric conversion.

A 48V, 1500W rear hub motor paired with a 20-inch wheel gives this Bdujhit kit a defined format for a compact-wheel conversion. Its listing also names a PAS sensor, LCD display, and seven gears, supporting an assisted-pedaling setup for commuting or short-distance cycling.

The rear-wheel hub arrangement means the kit centers the conversion on its supplied 20-inch wheel rather than a mid-drive. A PAS sensor supports pedal-assisted use, while the LCD display provides the listed display element for the setup. The seven-gear description adds a geared wheel configuration, and the 48V 1500W motor is specified at over 82% efficiency. Its stated maximum load capacity is about 150kg, a useful limit to factor into rider and cargo plans.

Skip it if you need a mid-drive or a wheel size other than 20 inches; the BAFANG BBS02B/BBS-HD is a mid-drive alternative.

This Bdujhit kit suits a 20-inch-wheel commuter seeking rear-hub assistance with PAS and an LCD display. Its wheel size is the key boundary: it is not the listed choice for a larger-wheel bicycle.

#4 · Best 26-Inch Hub

4. Mahugde 1000W 26-Inch Hub Kit

• Warranty Description: 1

Best for: 26-inch coaster-brake builds.

Why it ranks #4: Specifies a 1000W rear hub wheel for 26-inch bikes and includes a thumb throttle and pedal-assist sensor in the product details.

A 48V 1000W rear hub motor wheel specified for 26-inch bikes gives the Mahugde kit a straightforward wheel-size target. The listing also names a thumb throttle, pedal-assist sensor, and coaster-brake style, making those components and the intended wheel format key points for assessing a conversion.

The 26-inch wheel specification helps narrow the bicycle fit, while the aluminum frame and aluminum-magnesium-alloy wheel materials define the listed construction. A thumb throttle and pedal-assist sensor offer two named control elements for operating the motor, and the 1000W rating identifies its stated output. However, the included-components field lists one motor wheel only. Buyers should therefore account for that limited stated component list when planning the rest of the build.

Skip it if you need a listed multi-part conversion bundle; the BAFANG BBS02B/BBS-HD listing names several controls and installation components.

The Mahugde is a candidate for a 26-inch build that calls for a 1000W hub wheel, thumb throttle, and pedal assist. Its component list names only the motor wheel, so plan the remaining parts accordingly.

#5 · Best Fat-Tire Hub

5. HuaShuani 2000W Fat-Tire Hub Kit

• Warranty Description: 30 Days

Best for: Fat-tire hub conversion riders.

Why it ranks #5: Its 48V 2000W hub is designed for 20-by-4-inch wheels and lists five speed gears, cruise function, and an LCD display.

A 48V 2000W rear hub kit specified for 20-by-4-inch wheels gives the HuaShuani conversion a clear fat-tire focus. Its listing adds five adjustable speed gears, fixed-speed cruise, and an LCD that displays power, speed, mileage, faults, voltage, and current for ride and system information.

The dedicated 20-by-4-inch wheel format sets the fit boundary, while the 2000W motor is listed at 550rpm and a no-load speed of 34mph. Five adjustable speed gears let riders choose among the stated settings, and fixed-speed cruise adds a separate operating mode. The LCD’s voltage, current, fault, mileage, speed, and power readouts provide several kinds of information at a glance. The listing includes a wheel hub motor and assembly accessories.

Skip it if you have a standard 26-inch wheel rather than a 20-by-4-inch wheel; the Mahugde 48V 1000W kit is specified for 26-inch bikes.

Choose the HuaShuani if your build uses 20-by-4-inch wheels and you want the listed cruise mode and detailed LCD readouts. Its wheel format is the central fit consideration, not a universal hub conversion.

6. H-YEEU 80cc Gas Engine Kit

• Warranty Description: /

Best for: Gas-kit frame-fit planners.

Why it ranks #6: A complete 80cc two-stroke gasoline kit specified for many 26- or 28-inch V-frame bikes, with stated frame-clearance and tube-diameter limits.

An 80cc two-stroke gasoline engine and a stated top speed of up to 45km/h make this H-YEEU kit a motorized-bike option for compatible 26- or 28-inch bicycles. Its frame guidance is unusually specific: standard V-frame, 9–11 inches of clearance, and 25–29mm frame tubes.

That clearance and tube-diameter guidance gives buyers concrete measurements to check before beginning installation, while the 26- or 28-inch wheel range narrows the intended bicycle formats. The metal engine body and included installation hardware support a complete conversion approach. H-YEEU also states fuel consumption of 2.5 litres per 100km, a practical operating figure for planning fuel use. The listing describes a 2-stroke 80cc engine; this is a gasoline build, not an electric-assist conversion.

Skip it if you prefer electric assistance or your frame misses the stated geometry; the BAFANG RM G020.500.DC is an electric rear-hub alternative.

This H-YEEU kit is for a rider committed to a gasoline conversion and able to check frame geometry before fitting. Its wheel-size range is not enough on its own; the stated V-frame clearance and tube measurements matter.

#7

7. IMAYCC 80cc Gas Engine Kit

Best for: Hands-on 80cc installers.

Why it ranks #7: An 80cc two-stroke kit listed for 26- to 28-inch mountain, cruiser, and road bikes; its installation notes allow two to four hours.

An 80cc single-cylinder, two-stroke gasoline engine gives the IMAYCC kit its defining conversion approach for 26- to 28-inch mountain, cruiser, and road bikes. The listing sets expectations for installation too: allow about two to four hours for fitting and fine-tuning, with basic hardware skills and tools required.

Because installation includes fine-tuning, the stated two-to-four-hour estimate is useful for scheduling the build rather than treating it as a quick wheel swap. IMAYCC calls for basic hardware skills and tools, and specifically recommends reviewing the instructions and its installation video for first-time engine-kit installers. The 26.4-pound listed weight is also worth considering when choosing a bicycle and handling the assembly. This is a gasoline engine conversion, not an electric motor kit.

Skip it if you want an electric conversion or do not want a hands-on engine installation; the BAFANG RM G020.500.DC is a rear-hub electric option.

Pick the IMAYCC if you want a gasoline engine for a listed 26- to 28-inch bicycle and are prepared to install and tune it yourself. Its stated time estimate and skill requirements make planning part of the purchase.

#8

8. JAYGOVAN 80cc Gas Engine Kit

Best for: Fuel-conscious 80cc riders.

Why it ranks #8: Lists an 80cc two-stroke engine with 2.1kW output and a stated top speed of 23.61 mph, for buyers specifically seeking gas power.

JAYGOVAN pairs an 80cc two-stroke engine with a stated 2.1kW output and CDI ignition, giving this kit a gasoline-powered route to bicycle conversion. Its listing claims speeds up to 23.61mph and fuel use of about 0.53 gallons per 62.14 miles, useful figures for setting expectations.

The 2.1kW output and claimed top speed of 23.61mph describe the kit’s stated performance, while CDI ignition identifies the ignition system. JAYGOVAN also gives a reference fuel-use figure of about 0.53 gallons per 62.14 miles, which can help a rider estimate operating range between fuel stops. As an 80cc two-stroke engine kit, it calls for a gasoline conversion rather than electric assistance. The supplied details do not specify wheel-size compatibility.

Skip it if you need a stated bicycle wheel-size range before choosing; the H-YEEU 80cc kit lists 26- and 28-inch fit guidance.

Consider JAYGOVAN if you want an 80cc gasoline conversion and find its stated output and fuel-use figures useful for planning. The listing does not give a wheel-size range, so that detail remains a key fit boundary.

#9

9. YUNLAIGOTOP 100cc Gas Engine Kit

• Warranty Description: Free warranty within one year for…

Best for: Tunable 100cc engine builders.

Why it ranks #9: A 100cc air-cooled two-stroke conversion for 26- to 28-inch bikes, with a listed 1.9kW maximum power and upgraded CDI.

A 100cc two-stroke engine with a tunable carburetor gives the YUNLAIGOTOP kit a hands-on gasoline-conversion focus for 26- to 28-inch bikes. Its carburetor provides a choke lever, adjustable jets, and idle screws, while the listed air-cooled engine reaches a stated maximum speed of 48km/h.

The choke lever is positioned on the handlebars, and the main jet can be re-jetted; pilot jet and idle adjustments add further tuning points for builders working on engine setup. An upgraded CDI and 44-tooth sprocket are included in the full-kit description, alongside air cooling and kick starting in the specifications. The listed 26- to 28-inch range helps narrow bicycle fit, while the 100cc, two-stroke format makes this a gasoline project rather than electric assistance.

Skip it if you want an electric conversion or do not want kick starting; the BAFANG BBS02B/BBS-HD is a mid-drive electric alternative.

This YUNLAIGOTOP kit suits a builder who wants a tunable 100cc gasoline engine and can work with its carburetor adjustments. Its 26- to 28-inch fit range and kick-start method are important practical boundaries.

#10

10. Tiozuiu 110cc Gas Engine Kit

Best for: Air-cooled 110cc builders.

Why it ranks #10: This 110cc two-stroke kit is a gasoline conversion rather than an electric assist system, and its listing specifies fit for 26- or 28-inch bikes.

A 110cc two-stroke engine with air cooling and a CDI system gives the Tiozuiu kit its specific gasoline-conversion profile. The listing says the engine reaches 6,000rpm and identifies 26- or 28-inch bikes, making wheel size and engine type the first considerations for a prospective builder.

The air-cooling and CDI details identify the engine setup, while the claimed 6,000rpm figure describes its stated operating speed rather than a road-speed promise. Tiozuiu presents the kit as complete with parts and accessories for conversion, which frames it as an engine-and-components project rather than a simple wheel replacement. At 24.7 pounds, the listed package weight is relevant when handling the parts and considering the added engine assembly on a bicycle.

Skip it if you want an electric rear-hub conversion or need a stated road-speed figure; the HuaShuani 48V 2000W kit lists a no-load speed.

This Tiozuiu kit fits a builder seeking a 110cc gasoline setup for a 26- or 28-inch bike, with air cooling and CDI specified. Consider the 24.7-pound listed weight when planning handling and installation.
