Meet Samuel, a 17-year-old boy from Ghana who made his own motorbike with some wood a lot of ingenuity, and all the parts he needed to make it run on solar power:
much of the bike is built of reused parts and, without access to power tools, wooden elements that have been cut with a knife by hand. in a video, the bike is shown to have a functioning bell, a breaking system, lights, and a speaker which plays music. the young engineer notes that he manufactured and assembled his two-wheeler entirely on his own, and used timber pieces that would otherwise have been used as firewood.
