I wish they came in sizes as my tyre are bigger than the gizmo. And I wish I could see it. but all the fun is happening out of my eye sight and its just as well. I would probably get memorized and crash. What I can tell you is that it stops people as I ride by in the dark and they honk, oooh, and comment in such ways that I know it must be as fun as it looks. I am a tall girl and I don't have any friends who can reach my peddles otherwise I would ask. Some day I might find a tall stranger to ride it for me and then my review will change to one star owing to the lights causing the theft of my bike. Until then, I am getting another for the other wheel and telling you that you WILL be noticed by this thing. At least from the side.

Now here's a simple little device to make riding at night fun. This light has multiple patterns that provide a colorfully visual experience for safety also. I live in New Orleans and you'd see a lot of bike tours in the Frech Quarter and they would have a lot of them decked out of LED lights it looked like a rolling party so now you can have that every time you ride out in the evening.

The light is super easy to install and bright. There are two screws that come off and allow the light to be secured to the wheel. As soon as the wheel starts to turn, the light instantly activates. The light patterns are clear and fun. I can’t think of anything that I could change to make it better. Great value and quality product

I'm using it on my electric bicycle I was very colorful it's fun it makes me impossible not to see what I'm writing I just wish I could adjust where it stays on my spokes other than that it's great

Very cool looking at night. I saw people with them when we were camping so I wanted to try it. They’re a ton of fun to use at night. We got a lot of comments and questions of where to get them. I’m getting them for all of our bikes now.

Had a bit of a senior moment when the lights would not go through their different patterns. Found that the batteries I had installed were not new. After I changed the batteries go figure it worked just like they said it would. Love it.

I have now been using this for just over a year and it's still going great. I liked this light because it sits on the hub and not on the spokes, you only attach it to the spoke for stability. People notice the change in pattern allot and it is very bright. Even at slow speeds you can notice it. After 1 year I still have not needed to replace batteries.

I enjoy this product for riding downtown. However, when riding the trails, take the extra time and remove it. Trust me..it needs to be removed. This is my 2nd. I liked it enough to buy again.. I was riding trails and one end legit snapped after a jump. Learn from me and remove completely, if not cruising on pavement ;)

Hold a try mentality. Bought it . I did not expect such a successful repair.My little one loves his! The colors are bright and the patterns are awesome! Battery life is good and it was easy to install and doesn't get in the way!

Need to go a decent speed to look the best. Accidentally killed a set of batteries leaving the unit on. Apparently there is a standby mode so unit turns off when stopped and automatically back on. Didn't check to see if unit was on after a ride and batteries died. I'll make sure to spin the wheel to make sure it's off next time. Will update with pics / minimum speeds.

This light is very colorful and eye catching. It is perfect to put on your bike if you like to ride your bike when it’s dark. The light will make you feel very safe and cool when it’s Dark. My son loves it and even turned it on when it’s not dark. The light changes color and automatically turns on when you ride your bike. It is very easy to install. I highly recommend you to buy this. It is perfect!

Simple to install with great battery life! these led lights are great for my back wheel on my bike! it is great to ride in the evening , it was very simple to place, very light weight and water proof!

Bought 2 for 11 year old grandson's birthday. He LOVES them! So much cooler than the plastic straws and playing cards we had when we were kids. Also, he is visible at dusk, so maybe a little safer? For the look on his face and excitement in his voice, 10 Stars!

Quick and easy to install. At first it didn't seem to have the auto on and off feature but it was just we were impatient and didn't give it enough time to turn off automatically. My daughter thinks it is very cool but she doesn't ride quite fast enough to get the full effect. Ordering another for the youngest daughter once she conquers the two wheelers!

These bike lights are cool and my son likes them. I think it is very useful keep safe if you ride the bike on road at night.

Got here super fast. Pretty cool wheel light. Super bright. Just wish it had an off and on switch. Designs it makes are really cool.

Freezing winter time! Won't be able to tell you how they work until spring.

Super cool! My son loved it! I had to order more for all of our bikes! Very bright and pretty colors

My little one loves his! The colors are bright and the patterns are awesome! Battery life is good and it was easy to install and doesn't get in the way!

I was excited to get these. I read the reviews and ordered 2. Unfortunately I have an Ecotric electric bike. The light will fit on the front rim, but will not fit on the rear. I wanted to leave a review so future customers will be sure to make sure they will fit. My bad...

These are absolutely fabulously. I got them for my son’s bike when we are camping. The lights make him very visible when he goes for evening rides

So far so good. Brings lots of smiles to those I pass while on my bike. They can see me that is for sure!

Installed one of these on my daughters bike. Installation was pretty straight forward. It works... Just not all that impressed. A neat idea but can's say I have seen it do nearly all the patterns they show in the listing. Maybe she just needs to drive faster?

Looks really good at night and easy to attach

My kids love these! If you go fast enough you can see the designs clearly!
