It’s that time of year again: people across the United States are eating and drinking pumpkin everything, storefronts are decked out in fake cobwebs and creepy eyeball lights, and Inhabitat is launching the best Halloween costume contest to date with a chance to win a VANMOOF Electrified bike valued at a whopping $3,000. Which means the competition will be stiffer than ever. We aren’t looking for witch hats from Target, folks. We’re looking for the most innovative, thought-provoking DIY costumes made by you for you – not in some factory in China. Luckily, we have a host of brilliant past costumes to share as inspiration. So roll up your sleeves, evoke your creative ghouls, and enter Inhabitat’s 2015 Halloween Contest by October 31st, 2015 for a chance to win the world’s first intelligent electric bike complete with built-in GPS tracking.

THE PRIZE: A $3000 VANMOOF ELECTRIFIED BIKE

Tired of driving your car everywhere but reluctant to get all hot and sweaty on your way to work? The VANMOOF Electrified bike, nominated the electric bike of 2014 by the Dutch cycling organization RAI, will get you around town without wrinkling your clothes. Decked out with an intelligent interface built right into the dashboard, and powered by a small front wheel motor and integrated battery, this E-bike also protects against those with sticky fingers by making it easy to track in the event of theft. Sounds pretty good, right?
