When will the Revolights bike lighting system be available to the public?
To make the most out of our kickstarter funding, we’ve decided to specifically focus on completing the design for a few months. Our projected public launch will be in March ‘12 for $220 US. Pre-orders will be early next year and we’ll be sure to updated via our facebook page (Revolights), twitter (@revolights) as well as this site. Please stay tuned, we’re working very hard to get these to you as soon as possible.

Will it fit my bike?
Currently the Revolights bike lighting system is developed for Road and Hybrid 700 series rims, (aka 700c aka 622mm). If you don’t know your rim size please email any one of the founders with any numbers you can find in your tire/rim and we will figure it out! They will be adapted to more sizes in the future, this is just our initial target.

Is the Revolights bike lighting system waterproof?
The production version will absolutely be waterproof.

Is it possible to eliminate the blinking lights when the bike is stopped?
There has been a lot of feedback regarding the stationary illumination pattern and we are currently looking into other options, including solid arc illumination. The production version will not blink as seen in our YouTube video (http://www.youtube.com/watch?v=-UvO3QITwkU). We’ll be sure to provide an update when we have reached a final decision.

Could they be powered by wheel rotation?
Currently, they are not, but future versions are planned. On v4 we decided to use Lithium ion polymer batteries because they are an efficient way to power LEDs.

How easily can they be stolen?
The Revolights bike lighting system can only be installed (and uninstalled) with your wheel removed. Therefore they are not, in the current v4 easy to steal. They are only as easy to steal as ones wheel. We consider thievery a certain design priority.

Do the lights blink when the bike is moving, as it looks in the video?
In the video it appears that the lights are blinking. That’s an effect from the camera. The human eye will see a solid arc, in person, due to a phenomenon called persistence of vision (POV).

How much light does the v4 design project forward (in lumens)?
~134 lumens. Each LED is rated for 16.8 lumens of light, and since 8 LEDs are on at any one moment the total projecting forward is 134.4 lumens.

How long does a battery charge last on the v4 desgin?
~ 4hrs in the front; longer in back. The current battery spec’ed is a 1000mAh battery. 8 LEDs sink about 250mA total during operation, making for about 4h of runtime.

What does “patent pending” mean?
The term “patent pending” legally implies that a provisional patent has been submitted to the United States Patent and Trademark Office.

How much does the Revolights bike lighting system weigh?
The current version (v4) weighs approximately 6-8 ounces per wheel. The weight of the production version is not yet available as we are still finalizing the design.

Does speed affect the position of the illuminated arcs?
v4 includes a magnetic timing mechanism that calculates your speed and, based on an algorithm, maintains the illuminated arc size and position. There are plans to incorporate an accelerometer into future designs as a more robust solution.

Will the Revolights bike lighting system be able to handle extreme cold and snow conditions?
So far we don’t know how tough they’ll hold up riding in snow and being exposed to salt. We have had a number of messages from people in cold environments, so it’s definitely a big deal. Wet and cold will be of no issue but the impact of snow/salt on the rings over time could be another story. We are taking comments like this into account as we finalize the design. We’re on it.

Do you have a design the is compatible with motorcycles or wheelchairs?
This is a great suggestion and we’ve gotten multiple requests from motorcyclists and wheelchair users. While we do not currently have a design that is compatible, we do realize that a future design for use with motorcycles/wheelchairs is a huge opportunity and we’d love to achieve this goal in the future. Please stay tuned.
