Bicycle enthusiasts are the ultimate do it yourselfers -- they power their ride with their legs, and sometimes even charge their cellphones with the power generated from that ride! Show us all the ways you innovate on the road, and enter the Bicycle Contest.

We’ve partnered with Bicycles for Humanity, Boston Inc. to give away two 26” Mongoose Mountain Bikes, three Shimano Foldable Bikes, three Schwinn helmets, hydration packs, bike lights, and a whole lot more to make your ride a little smoother. All bicycle Instructables are eligible and we're offering a special prize for bike trailer projects. Share your project for a chance to win, and remember these words from John Howard when you build, “The bicycle is a curious vehicle. Its passenger is its engine."

How It Works

Write an Instructable

Create a new Instructable that fits the guidelines outlined in the contest description above. To be eligible, Instructables must be published between Mar 23, 2015 and May 4, 2015 (11:59pm PT).


Upon publishing your Instructable you'll see checkboxes for open contests. Select Bicycle Contest. If you have entries currently eligible for entry, it will also show up by clicking "Enter this Contest" on the right side of this page.


Entries are accepted by Instructables staff within one business day Monday - Friday. What matters is the submission time, not acceptance time.


A panel of judges made up of Instructables staff and respected members of the community rate the finalists. The averages of the ratings determine the winners.


When the winners are decided they will be notified and announced here on the contest page.
