MonkeyLectric launches Kickstarter campaign

You may have noticed that we don’t pitch very many Kickstarter campaigns here — and lord knows we field a TON of them every week. It’s sort of an unwritten rule here at…you want crowd funding? Take it somewhere else.

There are exceptions, of course, and here’s the latest from MonkeyLectric, which happens to make really great bike lights and has been good to us over the years, letting us test prototypes, shooting the breeze with us at Interbike, and advertising here to help us keep the site running.

Along with the lights we’ve reviewed here, MonkeyLectric also makes a “Pro” series light (mostly a prototype/custom-orderable) that is, well, frighteningly expensive. Enter the Kickstarter campaign — seeking a way to be able to mass-manufacture this light system at a better pricepoint:

MonkeyLectric Kicks Off Funding Production of Revolutionary New Bike Light via Kickstarter
Monkey Light Pro gives bike riders a novel way to express their unique individuality in a dazzling manner

BERKELEY, CA. MAY 22, 2013 – MonkeyLectric announced today the launch of a Kickstarter campaign to fund manufacturing efforts of its new product, the Monkey Light Pro, a unique bicycle light that utilizes cutting edge technology to allow users to display images and animation on their spinning bicycle wheel. The Pro series is for people who want to get their message out, express their individuality and be seen. The company is using the crowdsource fundraising efforts of Kickstarter to finance the manufacturing, which can be found at

The Monkey Light Pro, a more technologically advanced version of the popular Monkey Light Mini and the original Monkey Light models, features 256 LED lights and 4,096 colors that can be customized into designs uploaded via Bluetooth. Monkey Light Pro also allows users to upload up to 1,000 photos or 90 seconds of video. The Pro series is mounted to the bicycle wheel where it is easily viewed from both sides and multiple angles; the Pro is shock resistant and weatherproof.

Driven by MonkeyLectric’s eclectic backgrounds, the lighting art featured in their namesake product are designed by various graphic and psychedelic artists, including the well known David Ope, and provides riders the ultimate way to express their creativity. When the bike is in motion, it uses the “persistence of vision” effect to display the images that come pre-loaded or created by the users through its open source API.

Previous prototypes and models of the Monkey Light Pro are currently on display at major shows, in museums, as well as in Japan in collaboration with the Fukushima Wheel Project. This particular project utilizes a modified Monkey Light Pro attached to environmental sensors, where light patterns adjust to the levels of environmental pollutants in the area. The Kickstarter campaign hopes to make the product more accessible to developers, artists and the general public.

“Our first Kickstarter campaign allowed us to establish our own manufacturing line here in the USA,” said Dan Goldwater, MonkeyLectric’s CEO. “The success of that campaign helped us create 3 new jobs, make fixed capital investments in machinery, and relocate to a larger facility. With this campaign we hope to continue to invest in our manufacturing capabilities and make the world’s most advanced bicycle display system available to the market.”
During the campaign, Monkey Light Pro will be available to the first twenty pledges for $495, forty at $595 and 100 at $695. The price point after the campaign will be $895.

Monkeylectric M133 LED Bike Light: First Impression

Back in July, the cool folks at Monkeylectric sent us a few of their M132 LED bike lights to try out. Moe wrote up an article about it then.

I got an M132 in the mail in August and slapped it onto my Xtracycle. After one hard rainstorm, I had a “freak failure” when one of the soldered switch legs corroded, causing a loss of contact. Granted, this was an unusual occurence, so I contacted Dan Goldwater, founder of Monkeylectric, to get his insight into things. Dan was quick to offer me the opportunity to test the revised M133 model and a prototype waterproof battery-holder cover. I must add that I sent the failed unit back to Dan and he got it to work again by lightly brushing the corrosion with a toothbrush, so there was no “catastrophic, unrecoverable failure” here.

What’s different about the M133? Well, it has beefier switches that are reportedly much more water-resistant than the older M132:

It has a revised battery-holder with extra “lips” to help retain the batteries at higher wheel RPMs:

Also, a couple extra programmable patterns were incorporated into the memory of this device. Let me tell you this: the colors and patterns in this device are mesmerizing — I blew through a set of batteries just playing with this amazing light before I ever mounted it on my bike!

The prototype battery-holder cover is made of rubber and it is designed to seal most of the moisture away from the batteries and their contacts. Dan estimates them at around 90% waterproof, and I’d agree…I’ve been through a few medium-intensity rainstorms with the lights now and I haven’t seen any evidence of water or corrosion in the battery-holder. Dan also mentions that they’re working on incorporating a snap-on cover that mounts partially underneath the battery-holder during assembly and this new setup should be almost completely waterproof.

Mounting these lights is a breeze. Simply select an area on your wheel and ziptie the device in place with the included ties and rubber vibration-isolating pads. The whole process takes about two minutes.

Let's roll

The M133 has nine user-selectable patterns and sixteen colors to choose from. The user can select 1-4 patterns and 1-4 colors at a time or the device can be set to randomly cycle through all 16 colors and 9 patterns. There’s a lot to play with here. In addition, there are three separate “speed” menus; they allow the selection of the speed of pattern-changing, color-changing and overall “mood” (simple or complex patterns). Finally, there are two intensity settings: regular and extreme. In regular mode, a set of batteries should last 15-30 hours. In “extreme” mode (which is quite eye-searing), the batteries can be expected to last 4-6 hours. The regular or high-efficiency mode is plenty bright, though — and the lights will spread a bright patch 3-5 feet to each side of the wheel while it is in motion.

Here’s a couple still shots of the lights in action. First disclaimer: the colors are much more vibrant in real life and the patterns even more complex.

For even better photos, please visit our friend Derek Pearson at The guy is a professional photographer (rather than a point-n-shoot hack like me), and he was able to catch nearly the full intensity of these wonderful devices.

And, here is a Youtube video that gives you an idea of what these lights look like in action. I was dismayed to realize that the video didn’t accurately reflect what these lights are capable of, and Dan explained to me that, “the reason is that most consumer video cameras shoot at 30 frames per second, but your eye is closer to 10 frames per second. So your eye sees a tracer that is 3 times longer.” Basically, in real life the lights trigger a tracer effect that fills in any gaps in the pattern…it’s quite striking!

For reference, I have two lights mounted. They are both set to display all 16 colors and all 9 patterns randomly at medium-high speed.

The lights are packaged with an excellent instruction/programming and installation guide and all the necessary hardware needed to mount the lights. And, customer service from Monkeylectric is top-notch…they quickly answered any questions I had and handled my device failure with aplomb.

Do these lights work to help keep a bicyclist safer at night? Well, I’ve had a lot of amazing reactions…pedestrians hollering at me, motorists pulling up alongside me to ask about the lights (motorists, I appreciate the curiousity, but please don’t roll up next to me — it startles the hell out of me!). Visibility with these lights is quite astonishing, and the light is visible from the front and back as well as the sides.

We’ll see how these devices hold up under Florida’s grueling conditions…but for now, I’m hooked. These lights are fun, colorful and really make a bicyclist stand out in the dark — that’s a win-win in my book!
