The Monkey Light Pro has 4 bars of LEDs which are attached together inside your wheel. As your ride the system rotates, using Persistence Of Vision to create an image with its 256 full color LEDs. The Monkey Light Pro has sensors to track its speed, heads-up position and rotation direction. This allows the system to create stable, full-wheel images from 10 to 40 mph (15 to 65 km/h).

You won’t find this technology in any other product. Geek out:

A 2-axis accelerometer and 4 magnetic sensors are used to track speed, heads-up position and rotation direction. This keeps the display stable at different speeds, during acceleration and braking, and even if you ride backwards!

Double-sided display hardware. Text and graphics are readable on both sides of the wheel.

4-piece bolt-together design. 4 LED bars produce a full-wheel image at low riding speeds. The bars insert within the spokes and bolt together into a single rigid unit. Our design keeps the 4 bars accurately aligned (important for high display quality) and allows sturdy attachment to many common bicycle wheels.

Internal electrical loop bus. The electrical connectors of the 4 bolt-together LED bars form a redundant loop bus hidden within the assembled device. There are no exposed or dangling wires, and the redundant connectivity is vibration proof while riding.

Solid rubber molded construction. We developed this to meet the needs of year-round use on city streets, and proved it with our smaller Monkey Light products. Our proprietary 80A clear urethane resists cracking, scratching, clouding, water and dirt better than any type of hard plastic shell. It’s also thinner and lighter and will last years longer. We developed the process ourselves and operate our own manufacturing line here in California.

The Monkey Light Pro fits a lot of common bike wheels. If you have a less common type of wheel please check carefully below.

Adult bike wheel sizes: 26", 27", 28", 29", 700c

Hubs: The maximum wheel hub diameter is 58mm. All standard front wheel hubs are fine. All cassette (derailleur) rear hubs are fine. Disc brake hubs are fine. Rear hubs with a coaster brake and 1 or 3-speeds will fit. Rear hubs with internal 5-speed or more will not fit. Some dynamo hubs fit and some don’t, you’ll have to measure. Electric-bike motor hubs will not fit.

Spokes: Standard 32 and 36 spoke patterns will fit. Wheels with more than 36 spokes will not fit. Wheels with less than 24 spokes will not fit.

The Monkey Light Pro includes 4 separate pieces. Connect the pieces within the spokes of your wheel and bolt them together. The assembled unit straps securely to your spokes. Installation is easiest if you remove your wheel from the bike first.

Installation and setup take about 1 hour. We’ll make a video to show you how to do it.

If you want something that works right out of the box, check out the ready-to-ride option which is pre-installed on a Linus bicycle.

Application developers are welcome and encouraged. Our playlist, download and control software and API are available with an open-source license. Use Bluetooth wireless to download graphics and control the Monkey Light Pro. Make a moving installation with a bicycle, or check out our if you have any questions about your idea.

Many developers have already done amazing things with our prototypes:

The Fukushima Wheel project outfitted a bike with pollution sensors. As you ride around, it collects data from the environment and displays it on the wheels.

The Science Museum of Minnesota created an educational display.

Our own staff created an interactive 3D spherical display (video below).

The Museum of Brisbane made a video featuring the Monkey Light Pro:
