DPX Systems seems to deal exclusively in devices powered by handheld drills. In addition to the mini bike in the video above, they’ve made systems for wheelchairs, toolboxes, and hoists. The device costs $630, but we know most of you just need prompting that something is possible to be well on your way to building your own version. We’re still more fond of weed whacker machines.
Perhaps you’ve seen this image before: a young kid tooling around on a pair of inline skates, pushed forward by a weed whacker cycle. While the instructions for this device would seem fairly obvious (attach wheel to weed whacker) the writeup appears to be nonexistent. If you have any information, do let us know, but in the meantime, enjoy these other weed whacker powered projects.
