The Treadmill Bike by Bicycle Forrest is cracking me up. Yes, it’s a viral video to ever so subtly introduce you to their Bicycle CAD software, but that’s not going to stop me from writing about it. Besides the fact that there’s CAD software geared towards building bikes, which is cool by itself, I think it’s great that they had an itch and decided to build a treadmill/bike mashup to scratch it. For some reason I’m compelled to be athletic after watching this video, but I’m not quite sure if I want to go for a jog or ride a bike. It’s a little disorienting. Perhaps some sweet jumps will help me make up my mind. [via Dvice]
