"Groovy fancy yet simple chainguard" - Richard Masoner, Cyclelicious
We love bikes, but we hate oil and tearing that chains and sprockets do to our pants. Current solutions to the problem are clumsy and inefficient; we'd rather not have to strap our ankles or roll up our pant legs every time we ride. So, we created Revolve Bike Discs. These chainguards easily snap onto any bike sprocket and display intriguing rotating designs as you pedal. We're excited to get these out to the cycling commuters of the world!
Revolve Bike Discs attach directly to your sprocket and form a wall between your pant leg and the greasy chain and sprocket teeth. They can snap to any sprocket design via our patent-pending attachment system. As they rotate with your sprocket, their patterns create identity and optical illusions.
Check out our simple, patent-pending attachment system!
This ball and socket design allows you to easily attach Revolve Discs and exchange them for different designs, or remove the whole system. Snap it, swap it, scrap it. Our testers have been very happy with our system's smooth and universal actuation.
Want some extra attention?
We believe that any biker can quickly and securely install their own Revolve Disc. However, we would love to meet you! Therefore, we have included several reward levels of personal installation: we will meet you and your bike in person to install sockets and one, two, or three Revolve Discs! Please send us a message ahead of time to ensure that we will be in your area.
Revolve Bike Discs are universal!
There are many types of bicycle crankshafts out there in the world. Don't worry! We have visited many bike stores and tested on crankshafts of all sorts. The socket side mounts to any small part of your sprocket, then the ball attached to the Revolve Disc will accommodate for any sprocket alignment. The ball and socket also are just the right size to allow you to place your Revolve Disc on top of your derailleur and any small, ineffective chain guard that is currently installed in your bike. If you have any concerns, send us a message! We want to make sure that Revolve Discs work for you.
Designed with the road in mind.
We know that commuting can be tough on your bike and it's components, so we've chosen materials that can handle the challenges of the road. The discs themselves will be made of polypropylene, an extremely durable plastic that offers just enough flex to avoid damage from the bumps and bruises that are inevitable for a commuter's bicycle. Meanwhile, the ball and socket components of the disc attachment system will be injection molded in high wear-resistance nylon; nylon is a more lubricious plastic that will withstand the repeated flexing that occurs whenever a user snaps the disc on or off their bike. The attachment system will also feature an industrial strength, weatherproof 3M adhesive. The combination of each component results in a highly durable product; we expect them to last through several years of daily riding. Our prototypes have already made it through several months!
It's okay to pick favorites!

Exclusive design for early backers!
Be one of our first supporters! We're offering a limited run of 100 discs printed with the Optical Ring design in Kickstarter green.
Bike to Fight for the End of AIDS.
We want to support our friend, Leila Moinpour, and her team as they bike across the country for FaceAIDS. She is raising money for FaceAIDS to donate to Partners in Health, which brings AIDS-fighting medicine to needy people around the world, including the countries of Haiti, Rwanda, Mexico, and the USA. Once Leila raises this money, she will raise awareness with her pledge to bike from San Francisco to Boston over 63 days this summer.
To support this AIDS-fighting bike ride, we have designed the "Ribbons of Change" Revolve Bike Disc. Now you can support fighting AIDS not just with your monetary contribution, but daily as you commute with your bike and the Ribbons of Change Revolve Disc. Become the FaceAIDS ambassador to Leila by riding with this Revolve Disc!
Are you a DIY biker?
Early backers have the opportunity to create their own custom disc designs. Choose the custom design reward level, send your pattern to us, and we'll get it on a disc.
Nearly every backer will receive a snazzy Revolve Sticker and a sleek Revolve T-shirt!
You have the chance to get your name or your company's name out to nearly every backer! Simply choose a reward of $250 or more, and you will be on the back of the Revolve T-shirt. The greater your donation, the greater the size and higher the placement of your name among the other sponsors.
Help us share Revolve Bike Discs with the world.
We've built prototypes and have begun testing. Your backing will be used to fund our initial tooling costs and first production run. The breakdown of our costs is below:
47% // Injection Mold Construction
32% // Production Run Materials, Factory Time, Assembly, and Shipping
11% // Peripheral Costs (t-shirts, stickers, etc.)
10% // Offset of Kickstarter & Amazon Fees
A lot is left to be done. We have talked with manufacturers and are ready to invest in tooling as soon as we are funded. All we need is your support.
June - Final engineering validation & order tooling
July & August - Hard tooling, production sample testing, and tool modifications
August - Final production run
September - Package and ship Revolve Bike Discs to you!
We have received quotes from manufacturers for tooling and materials. We are developing relationships with our suppliers, and are working on finalizing our decisions. We are working with an onshore manufacturer, and we are very pleased with the ease of communication with them so far. However, we have a variety of backup vendors who are ready to respond to our needs if we have supply chain issues.
We anticipate that we will face the steepest learning curve as we begin to mass produce Revolve Bike Discs, and as we learn, we promise to involve our backers in decisions such as types of Revolve Disc designs and the snap fit of our injection molded ball & socket.
We have a wonderful group of advisors, supporters, and ralliers. You have helped us so much to get to this point, and we are looking forward to celebrating with you as we make this real!
