Brightz Bike Wheel Lights (2-Pack

Was skeptical when I bought these about them working on a smaller wheel and on an e-bike that obtains 20 plus mph speed. What I did do, and HIGHLY RECOMMEND is take your time in mounting them as tight to the wheel rim as possible and then use tie wraps every few inches to secure them further. (I needed to use extra tie wraps not supplied). I also took the battery controller and used the rubber straps to secure it to the spokes AND took several long tie wraps and secured it better. (This was one of the sticking points people mentioned in reviews about the straps breaking or loosening). By adding tie wraps I don’t have to worry they will break and result in disaster for me and the bike. I was also worried about cutting them to fit the shorter/smaller wheel, but this worked fine. I just made sure to cut after a light. I didn’t want to wrap excess throughout the tire like some suggested. I wanted a clean circle around the tire. Pros: Easy to install, being able to cycle through all colors or to stop on one color makes for endless choice and cool effect and you can change color to suit your mood every time your ride or stop the bike. Cons: Felt necessary to secure more than recommended with extra tie wraps, a bit hard to turn off and on when you have to reach through the spokes to find the push button. While securing it extra, it does make it more difficult when batteries need changing, but safety was first for me. Overall, it provides great light for dusk or night riding and great visibility of your bike on the road or trail, and boy do your look and feel cool! Buy them and have fun! All eyes will turn when you ride!

I've had these on my bike for about 8 months and haven't had to change the batteries once yet. They were super easy to install and haven't migrated from their original position, which was a concern of mine. They're bright, you can pick any solid color or let the colors cycle for a very cool show. I get loads of compliments riding at night and appreciate the safety of being seen while riding in the dark.

I got these for my boyfriend. So I originally ordered these from Amazon marketplace and by comparing the box I got to the genuine box photos, it was pretty obvious that I received knockoffs. Amazon was really good about refunding my purchase after I complained. Unfortunately, it looks like these keep getting sold by a series of slightly sketchy importers, using shifting names, and I don't fully trust that anyone selling Wheel Brightz under this listing is selling the genuine article. So I bought a new set of Wheel Brightz from the manufacturer's website. I am super bad at mechanical stuff, but installation was OK. Maybe 15-20 minutes per wheel. I got the pink one, my boyfriend got the multi-color. They both look great. The multi-color version looks kind of ugly when you're stationary compared to the other, more uniform colors, but it's totally sick when you're actually on the bike in motion -- it's like having a little rainbow whipping around your rim. For thirty bucks you bring a lot of joy to the world -- we probably average one direct compliment for every 1-2 miles or so of biking, depending on pedestrian density (and I overhear a lot of people talking about the lights but not directly to us). Typical encounters: A little kid in Bernal Heights shouted "you have a cool bike!" from his front porch. A (probably slightly intoxicated) pedestrian in the Mission told my boyfriend he had the coolest bike in San Francisco and gave him a fist-bump. Another stranger shouted, "I like your Playa bike!" (this is not my Playa bike, although these lights would be perfect for Burning Man.) The lights are very bright and visible, although you still need to have standard front and rear lights, as the Wheel Brightz can't be seen from directly behind or in front of the bike. Update: A year later, I still haven't had to change the batteries! I have had to order one replacement power supply for my boyfriend's bike, though -- we hang our bikes vertically by the front wheel on wall-mounted hanging racks and over time, the power cord got caught between the wheel and the rack enough times that it frayed and wore through. (You can avoid this if you are reasonably careful when you hang up your bike and avoid crushing the power connector cable -- it just hadn't occurred to us that this would be a problem until the cable broke, so we didn't bother trying to avoid it.) More recently, a segment (about a quarter) of the lights on one of his wheels went out, although you can't tell when the bike is in motion. Again, this is probably caused by hanging the bike by the front wheel. Update II: I've gotten several more sets of these, and they're still great, but I notice that in some of the sets I've bought more recently, in the initial packaging, the battery pack is screwed on so tightly I've had to use an electric screwdriver to open it -- it would be nice if they could fix that and not over-tighten the screws! Update III: I recently brought a pair of these to Burning Man. I noticed on the Playa that of all the different lighting schemes people used for their bikes, Wheel Brightz were the brightest and most visible -- far better than EL wire or front and rear lights. If you are planning to go to Burning Man, I would recommend Wheel Brightz as an absolute must-have for your bike.

Had these for a few weeks. Very bright and great for riding at night. Will buy again for the back wheel.

I get lots of happy comments when i ride my bike in the dark with these lights on. Easy to install

I ordered a 2 pack of purple lights but I've received 1 pink one and one purple one. I've also had Tue issue that the battery box plastic strap has snapped 4 times and is almost impossible to fix if you're out at the time.

This was a Christmas present for my grandson. He loved it. However it is yet to go into his bike. But will be done in the next day or so

These lights look cool, get a lot of attention, and are fairly easy to install.....but, the rubber strap that holds the battery box to the spokes is a weak spot that can break and the battery box will get caught up and tear the wires off. I installed these then came back out a few hours later only to find that the soft silicone rubber bands that hold the battery boxes on each wheel was broken and the battery boxes were getting caught on the frame. Luckily I noticed this as I was walking my bike out of the garage on not when I was riding. If it would have let go while riding the battery box would have been ripped from the wire leaving the units useless. I had to use electrical tape to hold the battery boxes to the spokes which is going to make battery changes a pain. I'm sure the manufacturer has received compaints about this issue. I doubt I'm the only one this has happened to. And I doubt the seller will replace the unit if the strap breaks and destroys the unit.
