Illuminate their imaginations.

What is a concert without stage lighting? With our new LED panels you can run lights directly off Pedal Power with no circuitry. Allow your audience to control the feel of the show by controlling the lights. The harder they pedal, the brighter the lights will be. Get kids excited to see their power work!
Our 12volt LED panels are made of over 1,000 LEDs. They can also be wired together to make 24volt lights! The panels are flat, which makes for a wide viewing angle of light, as well as being easy to store. They are mounted on a polycarbonate sheet, and covered with a bar-top finish to protect from damage. These lights are designed to easily carry on your bike for the ultimate Pedal Powered event.

These lights work well with hub generator rigs, like the Electric Fender Blender Pro and Mundo 500. You can also hook them up into a drop-in generator, which is compatible with all our Fender Blender models. They run off a battery, and can also be a great way to drain your pedal power system after an event. Or, use them while you’re packing up to keep some light on the gear!

Cost: $450/panel
Colors: Red, Blue or Green (Red & Blue make a great combo!)
Weight: 2-3 lbs
Made to order, 2 week turn around on orders.

We sell two types of complete Generator Bikes, and also generator wheels to install on your bike, in three sizes: 24″, 26″, and 700c. We sell two ratings of wheels: Cargo Strength, or NeverGonnaHitThePavement. If you’re only going to use these as generator wheels, you can get away with a lower-quality spec on the rim and spokes. But if you’re planning to ride to and from gigs, and especially if you’re carrying a load on the wheel, you need our Cargo Strength wheels, rebuilt with downhill mountain biking rims and 12 Gauge spokes.
You can put our generator wheels on any bike. We recommend a bike with a wide size range, low stepover height, and gears.
So what kinds of complete generator bikes do we offer?
Cargo Bike Generators:


The widest, most stable generator we sell, and boasting a very wide size range thanks to its innovative bottom bracket design. A single-speed generator, it’s extremely simple to use.
Generator wheels to turn any bike into a generator:

The most affordable way to access our frictionless generator technology. You simply swap the rear wheel of your current bike and throw it on one of our stable trainer stands. Great for custom bikes like El Arbol above, or for low-cost generators. Still extremely quiet and powerful.

Special lightweight or higher/lower voltage generators:
We’ll consult with you to find lighter weight options for bike touring or specific application.
Want your bike to generate power? Now you can, with a hand-built generator wheel from Rock The Bike. You can also use it to upgrade your Mundo into an electric bike.

These generators have gearing that is optimized for 24V systems but will function on 12V system. In order to use the power you generate, you’ll also need a Pedal Power Utility Box.
Requires 2-3 weeks to build from time of payment. Please specify desired output connector.
What kind of bike makes a good generator for our generator wheels?
Cost:
700 c – $450 (not suitable for cargo use) or $425 as add-on to Fender Blender Pro purchase.

We recommend you read and answer the survey questions posted on this page: http://www.rockthebike.com/basic-questions-to-consider-when-crafting-your-pedal-powered-stage/
This will help you clarify your target audience size, crew size, etc.
We also recommend you read and see the following posts and videos before diving in to the packages above.
What: Here’s a post that explains the components of a Pedal Powered Stage. Here we describe the basic building blocks of Pedal Power: Generators, Loudspeakers, circuits, etc.
Why: Check out Fossil Fool’s TED talk and other interviews on our About Us page to get the motivation for Pedal Powering music events. It’s about teamwork, community building, fun, and replacing gas generators.
Where: You can do it anywhere, but outdoor music events are the best settings. Our system uses cargo bikes to carry all the gear to events. Then we convert the cargo bikes into generators. See photos of past events:
Who: Your crew should include strong cyclists, outgoing ‘coaches’, techs, and performers. See pictures of the Rock The Bike crew in action.
How: Call us to get an estimate going for your gear package. We ship almost anywhere and specialize in building gear you can learn quickly and use dependably. You can also come to a Rock The Bike event and learn from us directly. Typical lead time for a Pedal Powered Stage is 6-8 weeks.

The Medium Pedal Powered Stage puts teamwork at the fore. 4+ people work together to power a live show.
Gosh, I wish this one had a better name. It’s an awesome demonstration, great bang for your buck.
4 Bikes / 2 Speakers / AC Power
250-500 people
Cost: ~ $13950
Also known as the SHAKE YOUR PEACE! rig. This is the smallest system we sell that allows you to truly power up a band. This option provides AC power; most bands have at least one performer who needs AC power for their instruments (amps, keyboards, effect pedals).
Crowd Size: 150-300
Setup Time: 30 minutes
Crew size: 4
Getting it there: 2 of the bikes are cargo bikes. 1 tows another.
Event space: Generators will take up about 12 x 8. Recommended stage size 10 x 14 including loudspeakers.
Storage space: All will fit in 5 x 10.
Lighting: Stage lighting panels can be connected directly to a bike or the included Utility Box.
AC Power rating: Comes with a 600 Watt pure sine inverter capable of delivering 1200 Watt surges in power. However, for practical purposes, AC power will have to be less than 200 Watts (continuous) for a successful event.
The gear / What you get:
Budget:
Options / Upgrades:
You supply:
Crowd Size: 100 to 250
Setup Time: 1 hour.
Crew size: 4
Budget: 12K
Optimized for what types of performances? Bands without many AC Power instruments.
Other notes: With a Medium sized Pedal Powered Stage, you need to be conscientious about what types of bands you work with. Specifically, instrumentation.
The gear:
We recommend:
Generators
2 Electric Fender Blender Pro
2 Mundo generators (upgradeable to Electric Cargo Bike):
3 Generator wheel + stand (upgrade any bike)
Circuitry: Split-Rail Utility Box with integrated 600 Watt AC inverter.
Pedalometer: 4′ tube, visible across a wide area.
Barebones downgrade:
No Pedalometer tube.
Bass upgrade:
Get a subwoofer.
Required additional gear purchase / sourcing:
2 speaker stands.
Modified JBL PRX 635 Loudspeaker with built-in Dubla and single Ultracapacitor brick.
All cabling included.
$5000
Substitution: Pedal Powered DJ Booth. Add 1-2 subwoofers. Keep only 1 monitor. Now you’ve got a righteous rig for dance music. If you’re working with a great DJ, your audio needs will be different than if you’re planning to Pedal Power bands.

Be at the forefront of the Pedal Power movement. Make history. The large Pedal Powered Stage includes enough loudspeakers, generators, circuitry, and interconnects for you to entertain a 1000-person audience, or larger. ‘No compromise’ sound for performers, thanks to ample monitors and AC power. The experience of playing on a Large Pedal Powered Stage is about the same as playing on a conventionally powered stage. To the audience it also feels and sounds like a medium-sized festival stage from a major festival.
Crowd Size: 300-1000
Setup Time: 2-4 hours
Crew size: 6
Getting it there: The entire sound system can fit on 4-6 cargo bikes. Use of cargo trailers will help reduce the number of roadies needed! Also, terrain will affect how much each roadie can haul.
Generators: We recommend 3 Mundo 500, 1 Boda Boda, 2 RTBGen, 1 Electric Fender Blender Pro, 3 generator wheel and stand.
Event space: We recommend a 10 x 20 stage. Additional space for Pedal Power generators, approx. 8×20.

Options / Upgrades:
You supply: 3 bicycles for the Generator Wheels, mics, mixer, snake, audio cables, speaker stands.
The technical needs of a Pedal Powered event vary greatly depending on things like audience size, venue, and power needs of musician’s devices. Over the past 6 years Rock The Bike has Pedal Powered events large and small. In this post we’ll try to help you arrive at what type of Pedal Power system would make the biggest impact for you.

Above: Shake Your Peace! performs during the Bay Rising Tour on their Pedal Powered Stage crafted by Rock the Bike.
Please consider and answer these questions:
- Outdoor v. Indoor. Doing anything in an outdoor space requires more power, as there are no resounding walls. What are the spaces you wish to use as venues? Do you have a photo of one of the events you host?
- Will you be doing nighttime events? Is there always light available? Do you have a need for Pedal Powered Lighting?
- What is your main motivation for doing Pedal Power?
- Audience size. How many people are in the crowd at the events you envision Pedal Powering?
- Do you need to provide AC power? Examples of why you’d need this include: charging cell phones, charging laptops, powering a mixing board, powering a power tool as an example of Pedal Power.
- Stereo v Mono. A 1 Bike / 1 Speaker setup is awesome for demonstrating Pedal Power and for public speaking. But to have a proper concert, it helps to have two mains.
- Related… Do you want or need to be completely off the grid? Sometimes you just want to demonstrate Pedal Power but in places where there is wall power. Other times you need to be completely off the grid. Do you have devices that need to stay ON (such as laptop, projector), and is there a source of AC power (Wall Power) available for these devices? Or would you like to be completely ‘off the grid’ and have Pedal Power be the source for all your power needs?
- Subwoofers. You can’t use subwoofers without extra pedalers. Subs are great for dance music. Not essential but really appreciated. And you can Pedal Power them!
- Do you want to be able to bike it all there? If you want to ride with the gear to the venues, there is a need for cargo bikes or trailers.
- Do you have a crew? Who are the people who will set up the Pedal Power system? Who will be the technical lead on this project?
- Do you want to have kids be able to participate? If so you will need extra bikes, because they want to pedal but cannot contribute that much actual wattage. At around 12-14, kids are big enough to contribute real amounts of power. Younger than that, they care greatly but won’t make a difference (power wise) and may take seats away from bigger kids or adults who can.
If you could please provide some quick answers to these it will help me craft a recommendation.
The 6th Annual San Francisco Bicycle Music Festival was our biggest ever and a milestone for our grassroots Human Powered Music Fest. Many thanks to the bands, fans, and our huge volunteer crew. Any one of the 3 phases of the day would have been epic enough. But we had a beautiful, idyllic daytime music festival in the park, an outrageous mobile party, and a post-modern urban block party all in one day. Daytime: 500+ people in a meadow, enjoying live music in the beautiful sunshine… Followed by a fire-truck dodging, freeway underpass screaming, Fossil Fooling LiveOnBike session, with captain Ariel using no electric assist to pull 3 performers and audio gear weighing 250 pounds on our Mobile Stage… Followed by a street party with an elevated stage, a glowing Bike Tree, and a 3-person pedal powered stage lighting system.

Above, two Mundo 500 generators in use at the Eugene Bicycle Music Festival. The rear wheel is elevated off the ground so that you can pedal in place and generate power.
| Number of Pedalers | Estimated Crowd Size Possible in an Outdoor Location |
| 1 | 200-500 (with One Bike / One Speaker) |
| 4 | 500 |
| 8 | 500-1000 |
| 12 | 1000-2000 |
| 20 | 2000+ We haven’t had enough chances to test at these power levels. |

The Electric Fender Blender Pro, our most compact, efficient generator.
What kind of generator?
The most effective generators are hub generators. They are efficient, quiet, and can convert a huge flow of power if the pedaler is cranking hard. The less effective ones are friction generators (tire rubbers). We recommend only hub generators, though for people on a long-distance bike tour, the extra weight is a drawback. Using efficient, quiet generators is better because it makes Pedal Power feel more impressive, which makes people want to pedal more, which in turn makes them want to ride bikes well after your event. Check out this page to see all of our generator options: the Mundo 500 (electric version of our favorite cargo bike), the Electric Fender Blender Pro (towable bike blender and generator), and generator wheels to turn any bike into a generator.

What kind?
Do not bother with Hi-Fi equipment (including home theater, bookshelf speakers, and computer speakers) or car audio gear. Neither of these were designed for large spaces and large crowds. If your goal is to produce an outdoor music event, you need to use “Pro Sound” equipment that was designed to reach larch crowds at events.
We sell Modified JBL PRX Loudspeakers. We modify and sell the full line of JBL PRX speakers, from the smallest wedge monitor (the PRX 612) to the 1000-watt subwoofer, the PRX 618. The ‘modified’ part means that we hack the circuit boards to allow them to run on DC power, bypassing the need for AC power (wall power). Since the conversion of Pedal Power from DC to AC and then back to DC inside the amplifier is wasteful, our Modified JBL PRX loudspeakers run 43% more efficiently than in AC mode. PRX loudspeakers are already some of the most efficient powered speakers commercially available, thanks to their Crown digital amplifier, so the additional power savings in DC mode makes them (quite possibly) the most efficient Pro Sound loudspeakers in the world! They make Pedal Power feel truly impressive. Pedalers have a big smile on their face when they hear how much powerful, crisp sound results from their good clean Pedal Power. This is a Rock The Bike exclusive offering.
PRX speakers are made of high quality plywood and have a durable coating. Although they’re heavier than some plastic speakers, they are relatively lightweight for Pro Audio gear, making them manageable to get to and from events by bike.
What ever loudspeakers you use, don’t forget the importance of proper elevation and positioning of the loudspeakers. Pro-sound speakers like the ones we sell at Rock The Bike have scientifically calculated dispersion cones that help the sound spread out to the sides. In order for these dispersion cones to do their work, your speakers have to be up in the air on a speaker stand.
How Many?
Generally you need at least two mains to do an event. But we know from experience that with 1 speaker, good music, and Pedal Power, people will dance. Generally speaking, divide the anticipated size of the audience by 100 to get the correct number of mains. This is only applicable for events up to 500 people. Beyond 500 people, using speakers on stands is not going to cut it. You need to start thinking about elevating the speakers even further, using subwoofers, and considering a Line Array configuration.

What about monitor speakers?
Monitor speakers are how the bands hears themselves during performances. Very few musicians can perform at their best without monitors. Generally you need 1 monitor for every 2 bandmembers of a full band. At least 2 for most bands. For public speaking events like a press conference, you can do without them. We sell the Modified JBL PRX 612 wedge monitor.
What about the speakers you already have?
You may already own certain Pro-sound gear or have musician friends who have gear. Can you just plug that in and roll with it? Basically, the answer is yes, but you may pay a significant penalty in both weight and efficiency with older PA gear. Many newer powered speakers have digital amplifiers. These generate less heat and therefore require less power/fewer pedalers. How can you tell if your speaker has a digital amplifier? Look up the model number online, or measure the wattage of your speaker using a Kill-A-Watt.
Can bands still use their own amplifiers?
Musicians are used to playing their guitar, bass, and sometimes keyboard through a specific amplifier. The amp is part of their instrument, part of their sound. Unfortunately, their amp increases your overhead. Ideally you will have enough bicycle generators that the extra wattage of their amplifier doesn’t matter. Asking a musician not to use their own amp is an unusual request. However in our experience, we get great results asking bass players to ‘go direct’ or play through the PA. This means that the bass player leaves her amp at home, and plugs the bass into a channel on our mixer, just like the lead singer. There’s still plenty of bass but there are fewer devices ON and therefore lower overhead. If you have a small Pedal Powered Stage with, say, 3-5 pedalers, you may not have enough raw power to keep additional devices on besides the bare essentials (the mains, a monitor, and the mixer). Fortunately, the bass players we’ve worked with are very happy with the sound they get at our events.


Can you store the energy created?
The circuit also includes whatever storage method you are planning to use. We use 30V Ultracapacitor ‘bricks’, which hold just enough power for a few minutes of music.
Why do I need protection circuitry and what type do I need?
The microprocessor brain in our Pedal Power Utility Boxes monitors the key system voltages and triggers relays that disconnect the pedalers from the system to prevent overheating and damaging the devices you’re running, or the Ultracapacitors. In addition to overvoltage protection, you also need fuses in case of short circuits. The input cables that connect the bikes to the system are long and are often subject to harsh conditions: people walking on them, tripping over them. Of course, you should tie these down as well as you can with reuasable Velcro ties. But you should also install fuses that prevent a bad yank from causing a meltdown. The circuit itself needs to be protected. We use Tupperware inside the box to prevent our microprocessor brain touching anything else and accidentally shorting. Your circuitry can’t be out in the open where it can be damaged in transit or where a metal wrench can be set down on it, causing a short circuit.
In a bicycle based system, any wire can be tugged or rub against a tire and degrade from wear. They need to be ‘strain reliefed’ and insulated. Connections from bikes to the circuit need to be both quick-connect for ease of setup and robust. We use Neutrik connectors, the industry standard for Live Sound.
Our current pricing structure is that most of your wiring is built in to the price of the other components. For example, if you buy a generator, you get an input cable. If you buy a speaker, you get a speaker power cable. We use only 14AWG gauge wiring for power cables that will see the outside world.

You will need a way to show Pedalers how hard to pedal. Otherwise they may drift off in their thoughts (and power output) or overpedal your system.

Our latest LED Pedalometer, shown above, is visible across a wide area, day or night. It’s controlled by a microprocessor that continuously monitors system voltage.

Our original Pedalometer (2oo7) involved a fan blowing air into a tube perforated with holes. The higher the system voltage, the harder the fan would blow and the higher the beer can would rise in the tube. It was quite motivating.
The ideal Pedalometer is the classic thermometer style, because it’s intuitive, making it possible for pedalers to get lost in the music while still providing the exact amount of Pedal Power needed. The pedalometer uses color-coding to show the pedalers when they need to pedal harder and when they need to slow down. Just keep it in the green.
The voltage information shown on the Pedalometer is also important to the sound guy/girl, who can raise and lower the overall listening levels and the bass levels according to the available system power. The Pedalometer also engages the audience in the Pedal Power experience. Even the bands get involved. When they see power levels dipping, they may make a funny comment about it between songs to help pedalers boost it back up.
Pedalers need to be coached. There are two essential aspects to doing this: the human touch, and accurate, up-to-the-second information about the system voltage.


Additional load-carrying gear to get to events by bike. This can include Bikes At Work trailers, Xtracycles, Mundos.

We help our event partners engage their communities to provide the greenest source of power possible. Read on to see how we do it!
We say a huge thanks to our amazing event partners from the first half of 2011. Sorry it’s taken so long! Here are some of the highlights. We look forward to Pedal Powering many more great events this year.

At the University of San Francisco’s Earth Day event, we pedal powered a Spin Art table, cranked out tasty bike blended smoothies, and got some good grooves going for the lunchtime event. Below, Anastasia and Nicco jamming, with 4 pedalers providing the amplification.
Sunday Streets

At Sunday Streets, San Francisco’s ‘Cyclovia’ event, we Pedal Powered a performance by Rupa & The April Fishes. Video below!
Concept to Concert

We helped get the groove going with a Pedal Powered DJ Booth at a charity fitness event in Malibu. Two Mundo 500‘s supported an 8′ wide DJ surface, and powered the two Modified JBL loudspeakers shown.

A month earlier — the sketch we scanned for the client.
Getting there:

We got better at getting to gigs by bike. Above, roadie Jeff shuttles a Mona Lisa-esque Giulia and a conga drum with a Mundo cargo bike, on a day we had more people than bikes.

We got a lot better at surfing. Above: Ariel delivering a Fender Blender Pro rental to the San Francisco Parks Trust for an event in Golden Gate Park.

We’ve had a perfect safety record, including on our amazing Bike Tree, El Arbol, shown above carrying two crewmembers and a conga.
Maker Faire
We hosted the 3rd annual Maker Faire -> Dolores Park Social Ride. 200 people showed up and we rode 21 miles to Maker Faire with awesome music and great spirits.

Maker Faire was the first event where people made leaves for El Arbol:

We had a blast at the 5th Annual Bicycle Music Festival, the world’s largest 100% Pedal Powered event, sponsored and co-founded by Rock The Bike.

Hundreds joined on the LiveOnBike parade from Golden Gate Park to Showplace Triangle. Two mobile acts performed on our new Mobile Stage, including 2 opera singers from the SF Conservatory of Opera, who performed aria duets, an act of street theater that prompted drivers to lean out of their windows and call “Stay beautiful!”.

Big thanks to Jay Broemmel from Complete Fabrications for welding the Mobile Stage! Thanks also to Mark, Kipchoge, and Ariel for many hours of help on the project.
We featured 13 acts on our Pedal Powered Stage.

After the LiveOnBike performance, we set up our Pedal Powered Stage at Showplace Triangle, an urban park.

Oregon Country Fair

We joined the University of Oregon Outdoor Program in producing 3-days of pedal powered music performances at Energy Park. Above, Rare Monk gets the dancing started.

The U of O Pedal Power crew take pride in biking to their events, shunning even the electric assist option of the Mundo 500.
