The Revolights Bike Lighting System consists of two narrow rings of LEDs that mount directly to each wheel using a series of clips and ring spacers.
The idea for Revolights came to inventor Kent Frankovich as he rode his bike in the dark, and wondered why the headlight — meant to illuminate the path he was cycling on – was so far away from the ground.
The good news is that the cars can see you in the dark leave ample room.
Revolights are designed for road and hybrid 700 series (aka 700c/622mm/24.5in.) and vintage 27in. rims only.
Battery packs are USB rechargeable and good for four hours of light per charge.
