This article features our 2 Modified JBL PRX speakers, 3 Mundo 500‘s, a pedal power Utility Box and the Biker Bar. Shaun O’Dell published this article in the Register-Guard on May 6, 2010.

Look for a bunch of music lovers on Saturday who plan to pedal — not peddle — on behalf of live musical acts.

Thanks to $10,000 in tourism grants, the University of Oregon Bike Program has been able to purchase equipment for this year’s Bike Music Fest that will help support live music acts by pedal power. The Bike Music Fest, which is incorporated into the Willamette Valley Music Fest, happens Saturday from 10 a.m. to 4 p.m. The larger music festival will continue until midnight.

The sLEDgehammer is an interactive light challenge that harkens back to the classic carnival Sledgehammer game. But here, the aim is to convert your peak power output to a beautiful light display. The sLEDgehammer is accurate, motivating, and visible from anywhere in the venue. It’s a fun way to get your event participants thinking, cheering, and breathing.
The 9.5′ to 11′ Tower and Stand are a great way to show pedalers their power.

Customize the color of the Generator Pro Frame.

The sLEDgehammer can be purchased as a single-player challenge or a dual:


Above: Get multiple sLEDgehammers to add a competitive element and a larger presence at your event.

Rules of the game:

Pedalers must overcome the challenge phase in order to see the reward sequence. The faster they pedal, the more lights turn on, making it harder and harder to keep increasing the system voltage. If they push the lights all the way to the top of the tower, and keep them on for 3 seconds, they beat the challenge and win the game. Their stored energy is then used up in a dazzling display of light.  A difficulty knob makes the game easier or harder. The peak effort required to win is about 200W for the Easiest setting and 600W for the Hardest. In the Dual sLEDgehammer, everything is the same. To decide the winner, you start the two riders at the same time and give the win to the one who pushes the lights higher in the tower or gets the victory sequence to display first.
Watch this video to see pedalers compete for sLEDgehammer victory at the 2016 Democratic National Convention!

The elements of a sLEDgehammer:

  • An efficient bicycle generator, such as the Generator Pro.
  • The sLEDgehammer circuit, which comes complete in a strain-reliefed enclosure with an Ultra Capacitor and all power cables.
  • 5 colored LED panels standing to a height of 11 feet tall.
  • Halogen lights at the top to win the game.
  • A wide base untippable tripod stand.
  • User manual Here.
The Bike: Any of our hub generators will do. But more than our other activities, pedalers on a sLEDgehammer tend to use their whole body to try to beat the game. You may benefit from the additional stabilization of your generator. The Electric Fender Blender Pro, with its 3′ wide stance, is particularly well-suited to this application.

The Circuit: The sLEDgehammer circuit is the brains of the operation, calculating watts as you pedal. The sLEDgehammer comes in an enclosed, strain-relieved circuit capable of handling 1500-Watt surges in power. Depending on how many LEDs you connect, you may need all that power handling. People will try to break this machine. The sLEDgehammer circuit runs cool, calm and collected even when your participants pedal their hardest.

The sLEDgehammer runs on an Arduino Pedal Power microcomputer, using the open-source Arduino platform. What this means is that you can optimize or change certain parameters to improve the activity.


Custom Installations:

The sLEDgehammer can be installed in several ways. Our favorite method is doing large custom installs like the ones shown on this page. They can either be done for a single event or on a semi-permanent basis. Custom installations use the same components: bike, lights, and circuit; and can be tailored to your event, activity, or facility. We work with you to design and implement the sLEDgehammer. We then provide either full installation and crew at your location or help and guidance for your crew prior to the event.

Recommendations for output devices, i.e. Light:

Please see above about “rules of the game”. There are two lighting segments of a sLEDgehammer — the Challenge Phase and the Reward Sequence. To make the Challenge Phase truly challenging, you need to connect at least 200 Watts of lighting, perhaps as much as 500 for the fittest riders.  The most impressive way to achieve this and the best option for a large space is to use LEDs for both the challenge phase and the Reward Sequence. This makes the Challenge Phase visible to much larger groups of people, which increases the crowd interaction. A lower-cost substitution is to use incandescent bulbs for the Challenge Phase, which has the benefit of highlighting the comparative energy efficiency of newer lighting technologies. With incandescents, you can make the Challenge Phase truly challenging. Incandescents will cost less* because you need far fewer of them to achieve the Wattage goals of the Challenge Phase. (* That’s also the reason they are worse for the environment.)



11 Foot Tall Tower, Tripod Stand, and Circuit: $3,600.00

Assembled dimensions:  

The Tower is 53″ long x 132″ tall, 43″ wide.

The Generator Pro is 56″ long, 39″ tall, 31″ wide.

Rentable: Yes! Find out more.

Custom Installation: Contact us for options and pricing.

Build Time: Made to order. Please give us 4 weeks to build the sLEDgehammer, 6 weeks for a Dual sLEDgehammer and 2 weeks for the sLEDgehammer circuitry only.

The Biker Bar uses regular bikes, requiring no customization

The Biker Bar uses regular bikes, requiring no customization

Previous designs of pedal power systems have relied upon special bikes customized with individual generators. The Biker Bar allows you to use ordinary bikes, which takes it to the next level. Everyday people not only power the concert, they save the concert, by supplying the last, critical piece of gear, their own bicycle. And the power, rather than being coupled electrically, is now coupled mechanically by the bar itself, making the Biker Bar an extremely intuitive system to understand. This makes the Biker Bar the most grassroots way to power your event’s stage.

You don’t have to wait until the general public arrives to get the Biker Bar set up with bikes. Organizers, volunteers, and staff can supply the bikes also.
