A bike rack that's lightweight, small enough to store in your car, easy to build at home, and only costs 50 dollars sounds to good to be true, right? It's not. This guy built a suction-based bike rack in just two hours with only his jigsaw and a drill.
He built the contraption using off-the-shelf suction handles, plastic cutting boards, and a commercial fork mount. All-in-all, it cost him just $44 for one mount and less than $100 to add in a second mount and a rear holder.
You can find his full instructions over at BikeHacks, and you can check out more of his photos over at his Photobucket account. The designer has reported that the bike rack has held up during both city and interstate driving, making it not only cheap, but also pretty reliable.
