Wheel lights can make your bike easier to notice from the side, but only when they fit correctly and stay secure on the spokes. BLITZU Bike Wheel Lights give you two wheel-mounted LED strips, seven selectable colors, and 15 lighting modes for night rides, family cruises, and decorative use. Their broad 12-inch to 29-inch wheel compatibility and included batteries make setup approachable. The main tradeoffs are an unpublished battery runtime, no verified IP water-resistance rating, and warranty wording that you should confirm before purchase.
Quick Verdict
Rating: 8/10, recommended with caveats
Best For: Families, casual riders, and commuters who want colorful side visibility without a tool-heavy installation
Bottom Line: The two-wheel kit offers a useful mix of visibility, color control, and wide bike fit. It works best as a supplemental light, not as a replacement for your required headlight, taillight, or reflectors.

What Are BLITZU Bike Wheel Lights?
BLITZU model S7-V73W-PTBS is a two-wheel LED lighting kit that mounts along your bicycle spokes. Instead of shining mainly forward or backward, the LEDs create visible color around the rotating wheels. That makes the kit useful for side visibility and for riders who want a more distinctive look after dark.
The package is designed for two tires and includes four AAA batteries. You can select one of seven colors with a button and switch among 15 modes, including constant and flashing settings. The manufacturer lists compatibility from 12-inch toddler-bike wheels to 29-inch adult-bike wheels, although unusual hubs, disc brakes, spoke patterns, and e-bike motors may reduce clearance.
Key Takeaways
- You get two wheel lights, so a standard bicycle can be equipped on both wheels from one package.
- Seven selectable colors and 15 modes give you more control than a single-color decorative strip.
- The listed 12-inch to 29-inch fit covers many kids’ and adult bikes, but you still need to check spoke and brake clearance.
- Four AAA batteries are included, but the manufacturer does not publish a verified runtime for this specific model.
- The lights improve side presence, but they should remain an add-on to your normal front and rear bicycle lighting.
Who Should Buy It?
Best For
- Families who want a two-wheel kit for a child, teen, or adult bicycle
- Casual riders who value color choices and easy button controls
- Commuters who want added side visibility alongside proper road lights
Skip If
- You need a light that illuminates the road ahead or replaces a rear taillight
- Your wheel has limited spoke access, a large hub motor, or tight brake clearance
- You need a published IP rating or a confirmed battery runtime before buying

Activ Life LED bike wheel lights help you stand out and stay visible from all angles for safer night rides and commutes. Designed for easy, tool-free installation on standard wheels, they add bright, durable illumination that enhances both safety and style.
How Do They Improve Visibility?
Most bicycle headlights and taillights are easiest to see from the front or rear. A wheel-mounted light adds a moving source of color along the side of the bike, which can help your bicycle stand out at intersections, driveways, and dim neighborhood streets.
The seven colors are red, green, blue, purple, yellow, light blue, and white. You can use a steady mode for a consistent outline or a flashing mode for a more noticeable pattern. The effect is decorative, but the side-facing placement also has a practical visibility benefit.
Before You Buy: Treat these as supplemental visibility lights. Keep using a suitable front headlight, rear light, reflectors, and any equipment required by local rules. The wheel lights do not project enough forward light to show road hazards.
Colors, Modes, and Controls
The main control advantage is choice. One button lets you move among seven colors, while the 15 available modes combine color selections with constant or flashing behavior. You can choose a steady white or colored outline for a calmer look, then switch to a flashing pattern when you want stronger visual contrast.
The lights remain visible while the bike is stopped, so the product does not depend on wheel speed to create a basic glow. As the wheels turn, the moving LEDs create a more complete circular effect. The simple control layout also makes the kit easier for children or occasional riders than an app-based system.
Fit and Installation
BLITZU lists the kit for wheels from 12 to 29 inches, which covers many toddler, youth, BMX, hybrid, mountain, and adult bicycles. The broad size range does not guarantee universal fit. Check the path of the light strip, the battery-pack location, spoke spacing, valve access, rim brakes, disc rotors, and any hub motor before installation.
Installation does not require tools according to the manufacturer, and an instructional video is available. Mount each strip evenly, keep loose sections away from the frame and braking parts, and confirm that the battery holder cannot shift. Spin each wheel by hand before riding to check for rubbing or snagging.
Pro Tip: Complete the first setup in daylight. After mounting, spin both wheels, squeeze the brakes, turn the handlebar fully, and take a slow test ride before using the lights at night.
Compatibility and Safety
Standard spoked wheels are the clearest match for this kit. Training-wheel bikes may work when the main wheels have accessible spokes, but the product is not designed to light the small training wheels themselves. E-bikes need extra attention because a hub motor, thicker wiring, or unusual spoke layout can block the mounting path.
The official product page does not provide an IP water-resistance rating for this model. Avoid submerging the lights or assuming they can handle heavy rain. If they get wet, switch them off, dry the battery area, and inspect the mounting points before the next ride.
BLITZU’s product listing mentions a lifetime manufacturer’s warranty card, while the company’s general warranty policy describes one year of coverage against manufacturer defects. Because those terms differ, check the current seller listing, registration steps, and written warranty terms before purchase.
How It Performs in Real Use
For Family and Neighborhood Rides
The two-wheel package is convenient when you want a balanced look without buying separate kits. Kids can choose a favorite color, while parents can select a steady or flashing mode that remains easy to notice during a slow neighborhood ride.
For Commuting
The side-facing LEDs can complement a proper headlight and taillight when you cross intersections or pass driveways. They do not replace road illumination, so commuters should view them as an extra visibility layer rather than primary safety equipment.
For Events and Casual Cruising
The seven colors and multiple patterns fit parades, campsite loops, group rides, and evening boardwalk trips. Constant mode gives you a cleaner wheel outline, while flashing modes create a more playful look.
For Long-Term Ownership
AAA power makes replacement batteries easy to find, but the lack of a published runtime means you should carry spares for longer outings. Recheck the mounts from time to time, especially after rough pavement, transport on a bike rack, or a wheel change.
Setup Tips Before First Use
- Test both light strips first. Install the included AAA batteries and cycle through the colors and modes before mounting anything.
- Clean the mounting area. Remove dirt from the spokes and rim area so the light and battery holder sit securely.
- Protect moving parts. Keep the strip and fasteners clear of brake calipers, rotors, chains, cables, and the valve stem.
- Balance the installation. Follow the video and spread the light evenly rather than leaving a loose section that can catch.
- Perform a clearance test. Spin the wheel by hand and listen for contact before your first ride.
- Check local rules. Use the wheel lights with any legally required bicycle lighting and reflectors.

Is It Worth the Price?
BLITZU Bike Wheel Lights offer strong value when you want to equip both wheels, choose among several colors, and avoid buying batteries before the first ride. The tool-free design also reduces the setup barrier for families and casual riders.
The kit makes less sense if your main goal is lighting a dark road, riding regularly in heavy rain, or getting a guaranteed number of hours from each battery set. You get the most value when colorful side visibility and broad wheel compatibility matter more than published weather and runtime specifications.

How It Compares to Alternatives
Brightz WheelBrightz is worth comparing if you have 20-inch to 29-inch wheels and prefer a single seven-foot light tube with a published weather-resistant design and stated runtime. It uses three AA batteries that are not included, while the BLITZU package covers two wheels and includes four AAA batteries.
Brightz also sells smaller spoke-light options such as OrbitBrightz and Spin Brightz. Those may suit riders who want compact decorative points instead of a fuller wheel outline. BLITZU makes the most sense when you want two wheel lights, seven selectable colors, and one package for a broad range of bike sizes.

Frequently Asked Questions
Do BLITZU Bike Wheel Lights replace a headlight and taillight?
No. They add side-facing color and visibility, but they do not illuminate the road ahead or provide the same directional signal as a front and rear light. Use them with appropriate bicycle lights, reflectors, and locally required equipment.
What wheel sizes do they fit?
The manufacturer lists compatibility from 12-inch toddler-bike wheels to 29-inch adult-bike wheels. You still need enough spoke access and clearance around brakes, hubs, cables, and the frame.
How many lights and batteries come in the package?
The package includes two wheel lights and four AAA batteries. That is enough to equip both wheels of one standard bicycle when the wheel layout is compatible.
How long do the batteries last?
BLITZU does not publish a verified runtime for this specific AAA-powered model on its official product page. Runtime can vary by mode, battery quality, temperature, and usage, so carry spare batteries for longer rides.
Can you manually choose a color?
Yes. The product page says one button lets you select red, green, blue, purple, yellow, light blue, or white. You can also switch between constant and flashing operation across the available modes.
Are the wheel lights waterproof?
The official page does not state a verified IP rating for this model, so you should not assume protection from heavy rain or submersion. Follow the product instructions, keep the battery area dry, and inspect the lights after wet conditions.
Will they work on an e-bike or a bike with training wheels?
They may fit when the main wheels have standard accessible spokes and enough clearance. A hub motor, thick wiring, unusual spoke pattern, or crowded brake area can interfere, so inspect your wheel before ordering.
What warranty do BLITZU Bike Wheel Lights include?
The product page mentions a lifetime manufacturer’s warranty card, but BLITZU’s general warranty policy states one year against manufacturer defects. Confirm the current written terms and any registration requirement with the seller before relying on coverage.
The Bottom Line
BLITZU Bike Wheel Lights are a good fit for families, casual riders, and commuters who want two colorful wheel lights with simple controls and wide listed compatibility. Skip them if you need primary road illumination, a confirmed IP rating, or published battery runtime. Their strongest points are the two-wheel package, seven colors, and tool-free setup, while the unclear weather and warranty details remain the main caveats.
