Urban bike lights are designed to get cyclists noticed at night. If a lighting system more “noticeable” than Revolights exists, I haven’t seen it. And judging by the overwhelming response I’ve received while riding with the wheel-mounted lights for the past two weeks, neither has anyone else.
Literally, within 15 seconds of leaving my house with the Revos for the first time, a passing cyclist hit the brakes to ask about the “badass wheel lights.”

Since then I’ve put in about 100 miles of night riding with the spinning LEDs slicing through the darkness and lighting my way. Reactions have ranged from pedestrian comments and inquiries like the aforementioned to a city bus matching my pace for several blocks so that passengers could take pictures of the lights with their smartphones. No, seriously. Without the lights, my bike’s not flashy enough to draw attention, and I’m not nearly good looking enough for it to have been for any other reason.
After two years of design and testing, Revolights are now on sale in the U.S. and Canada for $250 (sales will expand overseas in 2013).
Can you see me now? Good.
While $250 is steep for commuting lights, the Revos are something new and totally different. You can’t be missed riding at night with these blazers mounted on spinning wheels. Safety is their No. 1 theme, though the bling and pure coolness factor definitely isn’t lost on anyone either.
The concept for the design was born out of a practical dilemma. Fresh out of a mechanical engineering master’s program at Stanford, Kent Frankovich was frustrated by the helmet-mounted light that he had been commuting with at night.
“I thought it was silly that you would try to light the ground with something on your head,” said Frankovich. “The wheel was the closest thing to the ground. I just had to figure out how to make it work as a light source.”
Frankovich prototyped a wheel light shortly afterwards before joining entrepreneurial forces with business student Adam Pettler in October of 2010.
Side by side: Revolights’ ground–up system sets it apart
The San Francisco-based duo designed and produced several iterations of the lighting system before turning to the power of online crowdfunding to kickstart the operation last fall. The initial funding goal on Kickstarter of $43,500 was exceeded within a week, and after six weeks nearly 1,500 backers raised more than $215,000 for the bike light “REVOlution.”
Along with over half a million others, I was in awe watching the short video that showed the lights in action. Ironically (and painfully), I had been hit by a car due to a lack of adequate lighting on my bike several days prior, so I was thoroughly elated by the prospect of what I was seeing, though I still had to wonder if the lights could possibly perform as well in reality.
Over the past two weeks, testing the lights on night rides throughout the Twin Cities, I have found the answer to be a definitive yes.

Revolights aren’t the brightest lighting system out there. And they’re not trying to be. The Revos provide a full 360 degrees of visibility, with side visibility, in particular, that is second to none. On each wheel, eight 35-lumen LEDs illuminate the rider at all times without leaving oncoming drivers and other cyclists with burning retinas.
The forward-facing white lights illuminate the ground about eight to ten feet ahead of the front wheel. On rough roads, I supplemented the forward visibility with a bar light to help spot oncoming potholes.
The electronics are fully sealed and coated, which allow the Revolights to withstand wet conditions. Though, like all electronics, exposure to salt or alkaline dust on the road (for those of us in colder climates) can create issues. Keep ‘em clean.
Compatible with road and hybrid 700c wheels and 27-inch rims
How it works: The patented system consists of two narrow, polypropylene-coated aluminum rings ofLEDs that mount directly to each wheel using clips and spacers. Removable, USB-rechargeable lithium-ion batteries mounted to the front and rear hub supply power to the LEDs. Run time is about 4 hours on a full charge.
A pair of small magnets and an integrated accelerometer provide speed and orientation data to the rings, which allow the LEDs to synchronize with your speed, creating forward- and rear-facing arcs of light.
The complete system weighs in at a 1.5 pounds. For commuting purposes, weight is much less important than in a performance setting, so the weight is inconsequential in my mind.
During the day, the Revolights add a bit of aesthetic bulk, which pales in comparison to the aesthetic awesomeness they deliver as soon as the sun goes down.
Revolights: the whole package
The installation process is tedious but straightforward considering the amount of science that went into producing the lights. With the help of a mechanic at One on One Bicycle Studio in Minneapolis, it took an hour and a half to install the full setup.
Professional assistance isn’t necessary in most cases, and Revolights offers a full-spread of detailedinstallation videos, in addition to the included instruction manual.
Overall, we’re mighty impressed with the Revo design. The visibility out-shines anything we’ve tested for this purpose, and after rolling now for a couple weeks on these magic wheels the utter fun (not to mention the added confidence while riding at night) has yet to wear off.
Lead time on orders is now three to six weeks at Revolights.com, with all orders placed now shipping before the holidays. Just consider yourself warned that Revolights on the road will upstage your neighbors’ holiday yard decorations and the Christmas lights hanging in the trees.
