We are currently selling to North America and select European countries. Each country has its own set of rules and regulations. As a new product, it’s important that Revolights strictly adhere to these regulations. We’ll share our plans as we finalize them.

For Revolights international expansion and availability, follow along on Facebook, Twitter or Tumblr for updates.

The Revolights City v2.0 bike lighting system will retail for $229 USD + S&H + VAT on European destinations. Revolights are available only at revolights.com.

About 4 hours in the front; longer in back. Revolights are shipped with 1100mAh batteries. Eight LEDs sink about 250mA total during operation, making for about 4 hours of runtime.

Absolutely. We are currently using rechargeable Lithium-Ion batteries because they are a particularly efficient way to power LEDs. We also designed our own battery pack in order to maximize efficiency.

That said, we are firm believers that the energy created by wheel rotation is a sustainable, environmentally friendly power source. We have plans to incorporate dynamo power in the future.

Preventing thievery was an important consideration during the design phase. Because Revolights consist of a solid-ring body welded together during fabrication, the wheel must be removed from the bike in order to remove the Revolights. When you lock up your bike and wheels, you’re also locking up your Revolights!

Long story short, Revolights no longer make “disco patterns” while at rest. When properly installed, the white lights will always shine forward, and the red lights will always shine backward.

The original Revolights demo video depicted Revolights Prototype version 4 (or Pv4). We received a great deal of feedback regarding the dynamic lighting pattern created when the wheels were at rest. After significant testing and product development, we decided on a static lighting pattern for the wheels when at rest. Revolights Version 6 (the production version) uses an integrated accelerometer to allow the rings to index gravity at low speeds and form “arcs,” even when your bike is stopped.

The blinking lights in the original Revolights demo video is an effect caused by the camera’s inability to capture video at such a high rate of speed (frames/second). The human eye sees only a solid arc due to a phenomenon called persistence of vision.

There are a total of 24 LEDs on each wheel, 8 of which of are lit up at any given moment. Each LED is rated at over 35 lumens, but since our LEDs are continually rotating and lumens are a unit of flux (light/area) the most accurate description would be:

Revolights brightness = 8 LEDs x 35 lumens ea.

We went to great lengths to design the Revolights bike lighting system to stand up to wet conditions. The electronics are fully sealed and coated, effectively isolating them from the environment. That said, exposure to salt or alkaline dust on the roads creates issues for most electronics, Revolights included. Lithium batteries can also slow their discharge rate during long-term exposure to extreme cold.
