A15 Monkey Light colors

All of these ultra-bright colors, built-in!

The A15 comes with 23 built-in color options, selectable with the press of a button. Ultra-bright LEDs light both sides of your bicycle wheel, spokes, tires and the road around you to help keep you visible from all angles!

Colors change with your speed, or you can set it to show a single color. You can even set your A15 so it shows rainbows on your bicycle wheel!

Want to keep it simple? You can set your light to just white or just red with the press of a button.

A15 in ice

Built to last any adventure!

The A15 is rigorously tested to withstand the elements and your daily ride. It’s waterproof and iceproof* so that it can stand up to rain, snow, sleet, ice, road salt, puddles and river crossings.

And it’s durable so it can handle bumps, potholes, curbs, and jumps.

*We know you probably won’t be riding in the ice. But we take the quality of our wheel lights very seriously!

USA Assembly

Assembled in the USA of imported parts

We at MonkeyLectric run our own factory in California where we assemble the A15 in the USA of imported parts and program and test every single light.

If anything happens to your A15 Monkey Light, we stand by our lights. Let us know and our friendly staff will help you get rolling again.

And if you’re in the San Francisco Bay Area, we can give you a factory tour!

Smart Automatic On and Off

The best thing about the A15 is that it turns on automatically just when you need it. Triple sensors and a smart microprocessor turn on the light when it’s dark and when your wheels spin.

It saves power by turning the LEDs off when it’s bright enough outside or if you stop riding.

A15 BMX bike

Universal fit on bike wheels 16″ and larger

The A15 Monkey Light fits on most 16″ bike wheels and nearly any bike wheel with spokes 20″ and larger. This includes many kids bikes, folding bikes, mountain bikes, road bikes, beach cruisers, 29ers, fat bikes, and e-bikes.

The LED portion of the light attaches near the rim, and the battery mounts near your hub for wheel balance.

Easy USB Charging

The battery lasts up to 17 hours of riding and is easy to recharge: Just plug it in to a power source with the included USB cable.

A15 Speed Sensitivity

Colors change with your speed!

Our smart sensor technology can automatically change the color of your light as you ride, based on your speed! Challenge yourself to stay at the fastest color, or enjoy the light show as you accelerate or slow down.

There are 4 separate speed-sensitive options:

  • Speed Sensitive Rainbow: Red to Orange to Yellow to Green to Blue to Purple to White
  • Red to White: Red to Orange to Yellow to White
  • Blue to White: Blue to Purple to White
  • Our favorite, “Turquoise Sunset”: Cyan to Light Purple to White to Orange

All of these options are built-in to your light! You can select one by pressing the color button. Or you can select one of the other 23 non-speed-sensitive patterns!

Here’s a quick overview of how you install your A15 Monkey Light.
