Shit, Google-Youtube exclusivity strikes again. If anyone has a copy of this video in an unrestricted host, plz share. I would be quite interested in seeing this video, ideally from a copy that I can pass around to friends who are considering building ebikes.
This is pretty impressive. It looks like they’re using PLA, though? That seems wild to me. I skipped around, so if he described using something else someone let me know.
I don’t know if other people have some kind of magic print settings that make PLA a durable, high-strength material that I’m not aware of, but tbh this looks like building a bike out of hot glue and cardboard. I think it can be done with high-end filaments, though, and the work overall looks solid, so I’m dissing the guy. He looks like a pro to me, so I’m confident he knows what he’s doing, and I’m very much looking forward to seeing more of this project.
I built a friction drive for my bike with a load-bearing PLA motor mount (cheap crappy PLA, too), since I don’t have the equipment or ventilation for much else. With a bit of overengineering, it’s been doing great for almost a year now, despite all the heat and force thrown at it.
It seems like he is rapid prototyping with that material, not expecting it to hold very long. He also admits later in the video to having underestimated the forces and doing the calculation showing that it is way worse than he thought.
