Bicycles are beautiful and amazing things. As a form of transportation and source of adventure and fun they are at the top of the class. With warmer weather and longer days we have more and more chances to cruise along on two wheels and enjoy the world around us.

We want to see more people riding around on bikes and as motivation we're making the month of May Bike Month from Instructables and Park Tool. Show us some great bike-themed Instructables and win a Park Tool I-Beam Mini Fold Up HexWrench / Screwdriver Set as well as an Instructables t-shirt!

Your Instructable can be about bike maintenance, bike mods, bike riding, bike purchasing, or anything else related to bikes. Be sure to make it so great that more people will get out on the road and enjoy the two-wheel lifestyle!

UPDATE: We love two-wheelers, but others who use one or three wheels have asked to be included as well. How could we say no? They're now eligible as well.
