A low-cost e-bike conversion can mean buying a motor kit and a compatible battery separately; the listings below do not all confirm that a battery is included. The EXECYC 52V battery is a battery-only option for compatible systems, while the BAFANG rear hub kit suits commuters and the BAFANG front hub kit is a simpler front-wheel conversion choice. Compare voltage, motor position, wheel fit, and included parts before ordering.

BAFANG 48V 500W Front Hub Kit
This front-wheel kit is best for riders who want a moderate-power conversion and whose bicycle has a compatible front fork. Its motor is rated at 48V and 500W, with 65 N·m of torque. The stated fit is a 100 mm front dropout and 10 mm fork aperture, so measure the bike rather than relying on wheel size alone.
The listing describes manuals, video tutorials, most essential accessories, and US-based phone support. It was selected as a practical hub-motor option for commuting or off-road use. Battery inclusion is not stated in the supplied features, so confirm the kit contents and battery requirements before buying. Avoid this option if your fork dimensions do not match.
BAFANG Rear Hub Kit For Commuting
Choose this rear hub kit if you want a 48V 500W or 750W motor and a rear-wheel conversion. The listed maximum torque is 65 N·m, and the advertised top speed is up to 40 km/h. It supports rear dropout widths of 135–142 mm, a 10-speed cassette or less, and V-brake or disc-brake systems.
The kit lists pedal assist, throttle, walk assist, and conventional pedaling modes, along with cables, a controller, and other conversion components. These features make it a useful option for riders comparing everyday utility with multiple riding modes. Battery inclusion is not confirmed in the provided details. Check wheel, brake, and cassette fit before selecting it.
BAFANG Mid-Drive Kit With Optional Battery
This BAFANG mid-drive kit is best for buyers who specifically want the motor positioned at the bike’s bottom bracket. It offers 500W, 750W, or 1000W variants, depending on the selected configuration, and the listing gives torque figures of 100, 120, or 160 N·m. It is designed for chain-driven bikes with disc or V-brakes and specified bottom-bracket dimensions.
Listed accessories include a brake lever, chainwheel, thumb throttle, speed sensor, and other parts. The battery and LCD display are optional, so this is not automatically a complete battery-included package. Check the selected variant and bottom-bracket fit; the listing also notes that 73 mm screws are not included.
Varstrom Hub Kit With Multiple Power Choices
Consider this Varstrom kit if you want a choice of front or rear hub drive and multiple power levels. Its feature list describes 48V 1000W front and rear options, plus a 1500W rear option. Listed torque ranges from 66 to 78 N·m, with different stated speed limits and dropout measurements for the motor configurations.
The sine-wave controller and brushless, gearless motor are described as quiet and low-maintenance. This kit was selected for buyers comparing stronger hub-motor configurations, not for someone seeking the simplest low-powered commuter build. Confirm the exact wheel size, motor position, and dropout width when ordering. Battery inclusion is not specified in the supplied details.
EXECYC 52V 25Ah E-Bike Battery
This battery-only option is best for a buyer who already has a compatible motor kit. The listing describes a 52V battery with a five-pin baseplate for specified 48V or 52V brushless motor systems, including several power ratings. It also lists a smart battery management system, power switch, safety lock, and LED power indicator.
The stated charging time is seven to eight hours, and the estimated range is 55–75 km, depending on riding and road conditions, rider weight, hills, and speed. Compatibility must be verified against the kit’s voltage, connector, mounting base, and current requirements. It is not a motor kit, and the supplied details do not establish fit with every system.
Buying Guide: How To Choose A Cheap E-Bike Kit With Battery
Does the kit include a battery?
Do not assume a motor kit includes a battery. In these listings, the BAFANG mid-drive battery is described as optional, while battery inclusion is not specified for the hub kits. The EXECYC product is a battery by itself. Confirm the exact selected package and included components before checkout.
Which motor position fits your build?
Front hub kits can be a direct conversion choice when the fork dimensions match. Rear hub kits require checking rear dropout width, cassette limits, and brake type. Mid-drive systems require compatible bottom-bracket dimensions and a chain-driven bicycle. Physical measurements matter more than a broad claim of universal fit.
How do voltage and capacity affect battery choice?
Match battery voltage and electrical connections to the motor kit’s requirements. A 52V battery should not be treated as automatically interchangeable with every 48V system; verify the controller and manufacturer specifications. Battery capacity, riding conditions, assistance level, terrain, and rider weight all affect practical range.
What should budget-conscious buyers prioritize?
Compare the complete build cost, not only the motor-kit listing. Include a compatible battery and any required parts that are not included. Prioritize correct fit, clear component details, and support information over a high advertised speed or power figure. Also check local e-bike rules, which vary by location and configuration.
Frequently Asked Questions
Can I buy a cheap e-bike kit with a battery included?
Some packages may offer a battery option, but the provided details do not confirm a battery is included with most kits here. Verify the package contents before purchase.
Can I use the EXECYC 52V battery with any conversion kit?
No. Check the motor and controller voltage requirements, connector, baseplate, and other fit specifications before pairing it with a kit.
Is a front hub kit easier to install than a rear hub kit?
The Varstrom listing describes its front-wheel drive kit as simpler to install than its rear-wheel option. Actual installation difficulty depends on bicycle fit and the included components.
What measurements should I check before ordering?
Check wheel size, front or rear dropout width, fork aperture where relevant, brake type, cassette limits, and bottom-bracket dimensions for mid-drive kits.
