Review Content A Bike Enthusiasts Dream Product Being a bike enthusiast, I am quite aware of the safety needed when biking at night. Now I can entertain while enjoying a safe ride on my bike adventure! Its also a party celebration on my bike! Good and fun, Im recommend this product, be for bicycle i I loved fantastic put product on out door windmill , when wind turns the fan it gives a new meaning to outdoor light display. if u brought down price i would have bought 4 more to put on my antique car wheels for xmas parade. for other than bikes a little adaptation and i attached to my 9 ft. tall lawn windmill. when wind moves the blades it looks like a las vegas neon sign. Cool Wheels These are a great addition to any attractive bicycle or make a great gift for your grandchild.
