These do not look anything like the pictures in the description. They are much lighter and they never appear as a "circle" no matter how fast you go. They lit up but were not bright at all.

I bought these for my 6-year-old son's bike, but the "solid line" of color effect doesn't appear on small wheels. Still, they are kind of cool and increase visibility, which is good.

These lights are lots of fun for my kids, and they make our evening bike rides safer. Lights stay attached to spokes well and are easy to turn on or off. Battery life has been good.

I bought them because the description and photos make them seem like they just stay on, one solid color, but they don't These are blinking lights, they won't give you the effect shown in the pictures unless you're going pretty fast. I will be returning these.

I purchased these for my sons small electric dirt bike wheel spokes. However only half of them light up, disappointment. Right out of the package I would of expected all 6 of them to work and eventually replace batteries as claimed in the product description.

More than half the lights didn’t work when they arrived! Very disappointing! And waist of money and more junk to toss in landfill!

One of the lights was dead when I got it! Not well made. Hard to turn off without losing the cap. I am not impressed. Will not buy again or reccomend.

These are easy to install and easy to use. They have been helping us to take rides even with it getting dark so early. Wheels & Accessories.
