In the order of how often I'd use them, whether the lights were easy to install, the quality of the lights, how long the battery lasted, and other comments I had on them:

I would use these on my bike every 2 weeks or so on night-time rides on campus and would ride around for anywhere between 2 to 5 hours long.

The lights were sometimes a pain to install, but then again, I would install them in the dark surrounded by the other bikes in close proximity; if you aren't cramped like I was when installing the lights, it would be far easier to install the lights. On the occasions that I did not install them cramped having to worry about hitting other bikes, the process would take me about 3-7 minutes, otherwise it would take about 10-15 minutes. It's just setting up the plastic rubber bands on the center of your bike (axle? I only cared about brakes and whether my tires had air), looping the thin wire down to be near the edge of the rims, and looping the wire up and down over each of the metal tire line things. See the end for additional comments.

The lights themselves were bright and did not diminish in intensity during the 8 months or so that I used them. They were easily noticeable and helped in being seen when walking my bike through intersections at night. They were also bright and a nice green, nearly as bright as advertised (the advertisement has them to show as blinding X^D).

I do not remember if they came with batteries but surprisingly, I don't think I ever had to swap out the batteries during the time I used them. As I mentioned before, I used these lights for about 8 months for anywhere between 2-5 hours every two weeks or so.

Finally, my final opinion on these lights are that they are great and that I would buy them again. One thing to note is that you should not install them when stressed or tug on the wires hard as that is how I broke one of two that I purchased. The light still works and I am sure I can add something to prevent any accidents, but do be aware that the wires are a bit fragile. They are not cheaply made though, but should still be treated with some care. I hope this helped some of you, have a good one.

Look great on kid's bike. Easy to use "” push-button on and off. Also helps with safety. Shows up well.

Since I gotten this during the holiday, it feels like Christmas decoration on the go, but most importantly I am sure to increase my safety while riding at night.

This product is nearly perfect and I hope you will get one or more sets as well!

At the time that I received the wheel spoke lights I also had ordered the version that is a singular color. If I had not done that, then this review may have been given the 5* rating. Both are excellent products and you will have to decide which is the right one for you. But let's talk about the nuances.

The color-changing product is truly beautiful. It runs the color gamut from Red->Green->Blue with a few colors in-between as well. However, there is only one mode: On/Off. I appreciate that with the single-color model I received it can toggle between solid color and flashing. This product does not flash which is about 50% of the star I removed for the overall review. It also does not have a quick cycle mode. The only mode available is SLOOOOW color changing. This is fine and beautiful to watch, but I would have appreciated a quick color change mode -- maybe 4 seconds to cycle through all the colors rather than 10 seconds.

As a (pre-pandemic) daily bicycle commuter, I found the side-illumination these afforded my tires to be invaluable. My rear-facing tail light and 1000 lumen headlight have long been staples but bicycling through an intersection I always had to wonder whether the cross-traffic would notice me since drivers are rarely on the lookout for cyclists in my area. I feel like these wheel lights changed the game for me in a big way and I was very pleased to have them on anytime I was out pre-dawn or post-dusk. I even appreciated using them in flashing mode under the presumption that they may just give a little more visibility during the morning or evening commute when the sun was up.

The installation process isn't ideal and I found it a little more difficult and worrisome than I had pictured. I found the tiny bulbs (like regularly-spaced dew on grass) to get in the way of twisting around my spokes. It left me worried that I had or would damage them during the installation process. However, the material turned out to be remarkably durable from what I could tell and I was grateful that my 700C wheel fit the product perfectly for one trip around the outer rim. If I had a smaller wheel (or wanted to install on a kids bike) I imagine the number of trips around would feel tedious and a bummer that there aren't shorter versions available.

As the battery life starts to taper down I noticed that fewer colors were illuminating through the pattern cycle. It has been a long time since I changed the batteries so at least the product is still usable several months into daily use - kudos! I'm hopeful that when I eventually do swap out the batteries the rest of the colors will appear as before.

Regarding maintenance, if you get your bicycle tuned up, these little lights will likely have to be worked around as the bicycle mechanic trues the wheel spokes and if you hang your bicycle by the wheel, they will likely be an annoyance to you. But there isn't any interaction with the lights (hopefully) when changing a tube. It feels like once they are installed they pretty well stay where you put them. I've had a few times where I wished that the lights were capable of being more cemented in place but in general I haven't messed with their positioning along the spokes. Expecte a little movement, though, from where you install them.

So yeah, I am a huge fan of the bike wheel spoke lights and I can only hope that the innovations will be able to continue and keep this product improving as it matures. Great work Activ Life!

I bought three sets of these for my trike 7 years ago and only recently did one string stop working. So I reordered the same brand since it lasted.for so long. And these get used almost nightly and are exposed to wet weather and mud puddles. These lights are better at making me visible to traffic more than reflective gear or a headlamp. And kids enjoy how colorful the wheels are, they say it looks like a parade.
