A strong choice delivers a 20-inch rear wheel with a sprocket or freewheel that matches the bike’s drivetrain, axle spacing, and brake system. For BMX riders who want an installed sprocket, KHEbikes KHE BMX Rear Wheel stands out with its 16-tooth freewheel, 10 mm axle, and 165 mm axle length. The lineup also includes a cubsala wheel with a 9T freewheel, a WheelMaster BMX wheel with a freewheel hub but no included freewheel, and options intended for multi-speed or coaster-brake bikes.
Those distinctions matter: a wheel can be the right diameter yet still fail to fit the frame or work with its brakes. Compare the listed hub, spacing, sprocket, rim, and brake details before choosing.
KHEbikes KHE BMX Rear Wheel is the strongest match because it is a 20-inch rear wheel with a 16-tooth freewheel already mounted. Its 10 mm axle, 165 mm axle length, and 36-hole aluminum rim make the key fit and wheel details explicit. Check your frame’s axle requirements and brake setup before ordering; the listed brake style is rim brake, and the product data does not specify its installation width.

- Material: Alloy Steel
Best for: Chrome Steel Replacement Wheel.
Why it ranks #6: The 20 x 1.75 steel wheel is listed for a BMX one-speed freewheel, but its freewheel is sold separately and the rim strip is not included.
A chrome-finish steel rear wheel gives this 20 x 1.75 Wheel Master a straightforward BMX replacement format, with a bolt-on mount and 36 holes. It is a one-speed freewheel-style wheel, but its freewheel is sold separately, so buyers can choose that component independently.

- 36-hole construction

7. WheelMaster Black KT Wheel
- Wheel Size: 20 in
- Rim Size: 20 in
- Material: Aluminum
Best for: Single-Speed Coaster Brake Wheel.
Why it ranks #7: This is a 20-inch coaster-brake wheel with a 3/8-inch axle and 110 mm spacing, not a listed sprocket or freewheel setup.

View on AmazonAvoid a drivetrain and brake mismatch
A wheel can fit the frame and still be incompatible with the bike’s drivetrain or brakes. The products here illustrate why the word sprocket needs clarification: KHEbikes KHE BMX Rear Wheel includes a mounted 16-tooth freewheel, while WheelMaster Chrome Steel Wheel is for a one-speed freewheel but says the freewheel is sold separately. WheelMaster Black BMX Wheel lists a freewheel hub, not an included freewheel.
Coaster-brake wheels are a separate system: WheelMaster Black Steel Wheel has an 18T cog driver, and WheelMaster Black KT Wheel is also listed with coaster brakes. Neither should be treated as an interchangeable freewheel wheel based on tooth count alone.
Before ordering, identify whether your bike uses a freewheel or coaster brake, then confirm the wheel’s brake style and whether the sprocket is actually included. A listing’s wheel diameter by itself does not establish drivetrain compatibility.
Check axle dimensions, not just wheel diameter
A 20-inch label does not establish that the wheel will fit your frame. The listings show different axle details: KHEbikes KHE BMX Rear Wheel has a 10 mm axle and 165 mm axle length, while cubsala Yaphet Rear Wheel lists a 175 mm axle and 110 mm installation width. Several WheelMaster options specify a 3/8-inch bolt-on axle and 110 mm spacing.
These dimensions describe different aspects of fit, so compare the relevant measurement on your existing wheel and frame rather than assuming that matching 110 mm figures settle every fit question. Also check tire width: many options are specified for 20 x 1.75, while WheelMaster Black Steel Wheel describes compatibility with tires from 1.95 to 2.225 inches.
Confirm the rim and tire requirements, axle type, spacing, and brake arrangement together before buying; the provided listings do not give every fit dimension for every wheel.
How to Choose a 20-Inch Rear Wheel
Sprocket or freewheel inclusion
Look for an explicit statement that the sprocket or freewheel is included and mounted. KHEbikes KHE BMX Rear Wheel comes with a 16-tooth freewheel already mounted, and cubsala Yaphet Rear Wheel is described with a 9T single-speed freewheel. WheelMaster Chrome Steel Wheel requires a separately purchased freewheel, while WheelMaster Black BMX Wheel lists a freewheel hub without confirming an included freewheel.
WheelMaster Black Steel Wheel’s 18T cog driver belongs to its coaster-brake setup, not the same arrangement as a freewheel. A buyer replacing a BMX freewheel can favour the first two; someone sourcing components separately may consider the WheelMaster hub options, but should verify compatibility and what arrives in the box.
Axle and frame fit
Match axle type and dimensions to your frame before selecting a wheel. KHEbikes KHE BMX Rear Wheel lists a 10 mm axle and 165 mm axle length; cubsala Yaphet Rear Wheel lists a 175 mm axle and 110 mm installation width. Several WheelMaster wheels specify a 3/8-inch bolt-on axle and 110 mm spacing.
These figures are not interchangeable: axle diameter, axle length, and hub installation width each affect fit. Riders replacing an existing wheel should compare its measurements with the candidate listing, including how the axle attaches.
The 110 mm options may suit a frame designed for that spacing, while the KHEbikes and cubsala listings offer different axle details. If a listing omits a measurement you need, verify it before ordering rather than relying on the 20-inch size.
Brake type and rim construction
Choose a wheel whose brake system matches the bike, then consider rim material and construction. Most listed wheels specify rim brakes, including the KHEbikes, cubsala, and WheelMaster alloy or steel freewheel options. WheelMaster Black KT Wheel and WheelMaster Black Steel Wheel are identified as coaster-brake wheels, which serve a different setup.
The wheel materials also vary: KHEbikes uses an aluminum rim, cubsala lists an aluminum rim, and some WheelMaster options have steel rims while others use alloy. A rider with rim brakes should focus on the rim-brake listings and confirm rim compatibility; a coaster-brake bike should consider the appropriate coaster model.
The supplied details do not establish that a rim-brake wheel will work with a coaster-brake frame, or vice versa.
Which 20-Inch Rear Wheel Should You Choose?
Choose KHEbikes KHE BMX Rear Wheel if you want an included, mounted 16-tooth freewheel and its 10 mm axle and 165 mm axle length suit your bike. For a 9T single-speed freewheel and clearly stated 110 mm installation width, consider cubsala Yaphet Rear Wheel. WheelMaster Black BMX Wheel is an alternative when you need a black 20 x 1.75 rim-brake wheel with a 3/8-inch freewheel hub and can confirm the freewheel separately.
For a 5/6-speed freewheel setup, consider WheelMaster Silver Alloy Wheel. Choose WheelMaster Black Steel Wheel only for a compatible coaster-brake bike using its 18T cog driver.
WheelMaster Chrome Steel Wheel requires a separate freewheel; WheelMaster Black KT Wheel is also a coaster-brake option, not a freewheel match.
Related Buying Guides
Frequently Asked Questions
How can I check whether a 20-inch wheel’s axle and hub spacing fit my bike frame?
Check your frame’s required axle type, axle diameter, and distance between the dropouts, then compare them with the wheel’s listed details. The KHEbikes wheel lists a 10 mm axle and 165 mm axle length, but its installation width is not specified. Confirm that measurement with the seller or manufacturer before ordering.
Can I replace a freewheel with a different tooth count without changing the chain?
Sometimes, but it depends on the tooth-count difference and whether the chain can be adjusted to the resulting length and tension. A 16-tooth freewheel and a 9-tooth freewheel may require different adjustment. Check your drivetrain’s compatibility and available chain tension before switching; do not assume the existing chain will fit.
How do I tell whether my bike uses rim brakes or a coaster brake?
Look for brake pads that press against the wheel rim; that indicates rim brakes. A coaster brake is built into the rear hub and engages when you pedal backward. Match the replacement wheel to the bike’s brake system: the KHEbikes wheel is listed as rim brake, while some WheelMaster options are coaster-brake wheels.
What should I verify if a wheel listing does not state installation width?
Measure the distance between your frame’s rear dropouts and confirm the wheel’s hub or installation width with the seller or manufacturer. Do not treat axle length as a substitute for installation width. The KHEbikes listing gives a 165 mm axle length but does not specify installation width, so check that fit before ordering.
When should I choose a coaster-brake wheel instead of a freewheel wheel?
Choose a coaster-brake wheel only if your bike is designed for a coaster brake and its hub configuration matches. The WheelMaster Black Steel Wheel is listed with an 18T cog driver, and the Black KT option is also a coaster-brake choice. These are not substitutes for a freewheel setup.
Final Words
For a straightforward freewheel choice, start with the KHEbikes wheel if its 10 mm axle and 165 mm axle length suit your frame and you want the mounted 16-tooth freewheel. Consider the cubsala for its 9T freewheel and stated 110 mm installation width, or WheelMaster Silver for a 5/6-speed freewheel setup. Confirm axle fit and brake type before choosing; coaster-brake options suit only compatible bikes.
