Generators available from Rock The Bike

We sell two types of complete Generator Bikes:

Generator Pro (our custom frame with wide size range and great branding possibilities)
Electric Fender Blender Pro (same but includes a bike blender so you can do two activities)

And we sell two solutions for turning any bike in to a generator:

– the Roll Up Generator Stand
– the Generator Wheel 


Generator Pro

When you do events with Pedal Power, especially with groups of pedalers, it’s good to have a simple, comfortable bike that looks inviting and leaves no option but to get on and pedal. The Generator Pro is that bike.

It has no gears, no brakes — only the seat to adjust. The handlebars don’t even turn. Nothing rubs the tire, nothing gets hot and no parts wear out when people pedal continuously for hours at events.

What it does have is a large and effective brushless generator wheel. The size of it creates a flywheel effect that smoothes out people’s pedal strokes. The magnets and coils inside the generator never touch each other, and there’s nothing rubbing on the tire, meaning that all the pedal energy goes into electricity instead of heat. The power comes through a cable at the center of the wheel.

The hub is rated for more power than even the strongest Tour de France riders can summon.

The frame of the bike has a very wide size range. You’ll see 7-year-olds high-fiving adults as they pedal alongside each other. All you have to do is make sure the seat is adjusted for each rider. The ease, comfort, and fun of people pedaling in groups are what this bike was designed for.

This generator is for customers who want the best, like the way it looks in a group, and want the benefits of its simplicity

The lack of unnecessary features in this high-performance generator allows your staff to direct its attention to other things at your events, like people!

Key features

  • Compatible with any Rock The Bike electrical activity, such as the Recharge Station, the sLEDgehammer, or live sound.
  • Consistent performance.
  • Cruisy looking and comfy.
  • Looks great in a group at events.
  • Powerful gear ratio.
  • Uses the same frame as our bike blenders — you can add a blender later or get both now in the same package.
  • Can be branded — see our examples.
  • The Generator Pro is not a complete activity by itself. Pedaled on its own, it will have no resistance and the wheel will just spin faster and faster. You have to match it to one of our compatible Electrical Activities.

It has all the features of the Generator Pro, plus you can blend smoothies! For more info, please go here.


Roll Up Generator Stand

Rock The Bike's low cost, high-performance, smooth rolling generator.

Rock The Bike’s low cost, high-performance, smooth rolling generator.

Roll your bike on up to this sturdy stand, engage the generator, and voila! — you are immediately ready to create some serious pedal power!

Designed for continuous all-day use at events, this DC power generator stand is an efficient yet affordable way to get the Rock the Bike level of performance for one or many riders. Get several stands to involve local team members and volunteers who can bring their own bikes to an event.

Our child-sized version makes a good choice for teachers who want to do a demonstration of alternative energy in the classroom. Unique among every available bike generator, the Roll Up features a clear window where you can see magnets on the moving part spin past coils on the fixed part.That’s where muscle effort converts to electricity, and you can show it to your students!

The ride is easy on your bike, and easy on your body. While other bike generators shred tires, whine with inefficiency and aren’t nearly as fun to pedal, we engineered the Roll-Up with a four-times-bigger roller that both positively grabs your tire and creates a flywheel effect to smooth out generation.

The large contact patch formed between the 6” roller and your tire means less roller pressure is required to maintain contact. You won’t see any deformation of the tire. More of your good clean Pedal Power goes into the device you’re powering.

We make our rollers out of our own gritty composite similar to the concrete that tires were designed to roll on—producing a smooth, quiet, efficient ride.

Key Features

  • Clear, built-in indicators show when you’re using it correctly: LEDs inside the DC generator glow at 12-24 volts.
  • The generator is designed to accept more power than humans can generate, so the Roll Up never gets hot.
  • Highest power capacity tire-rolling dynamo on the market.
  • Almost any kind of bike works, see the requirements here.
  • Standard model fits 24”, 26”, 29” and 700c wheels; small model fits 20” wheels.
  • Use your bike gears to adjust level of challenge.
  • For group events, pair your Roll Ups with a range of bike sizes to fit a variety of riders. [photo from Alabama]
  • Generates 0 – 30v DC  Anderson connector output.
  • Using a 21-speed bicycle or higher will give you the greatest range of output voltages.

The Roll Up is not a complete activity — you’ll still need something to power.


Generator Wheel

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 stands. Great for custom bikes or for low-cost generators. Still extremely quiet and powerful.

Your bike can now be a generator, every bit as powerful and quiet as the ones we use at Rock The Bike events.

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 a 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 the time of payment. Please specify the desired output connector.

What kind of bike makes a good generator for our generator wheels?

  • Bikes with a wide size range
  • Bikes with good standover height
  • Bikes without rear suspension. Suspension (or “shocks”) makes a bike less stable when it’s mounted on a Stationary Stand.
  • Bikes with a front derailleur and 2-3 chainrings. These have a wider gear ratio, making it easier to find the right gear ratio.

Special lightweight or higher/lower voltage generators: We’ll consult with you to find lighter weight options for bike touring or specific application.

700 c – $450 (not suitable for cargo use) or $425 as add-on to Fender Blender Pro purchase.
26″ – $525 (suitable for cargo use)
24″, 20″ – $525 (not suitable for cargo use.

Rentable: Yes

In the Box:

  • Wheel with Generator Hub (in selected size)
  • Rectifier cable with 2′ lead to wheel and 20′ cable for the DC output.
  • 7-speed freewheel with 11-tooth cog for highest voltage range, or 1 speed on Electric Fender Blender Pro
