Though [Ivan Miranda] calls the 3D printed vehicle in his recent video a motorbike, what he ultimately pulls out of his suitcase is clearly a scooter. Linguistic confusion aside, the “Mirandetta” looks like an awesome build andĀ pulling a scooter out of your suitcase and whizzing past everyone in the taxi line just sounds amazing, especially knowing you made it yourself.
Aside from a whole lot of filament, he’s got a couple of tool batteries for hot-swappable energy that Airport security shouldn’t mind too much — provided you carry them with you, anyway — plus the usual e-bike motor and electronic speed control you might expect, and lawnmower tires which you might not. The narrow 3D printed rims round over the normally-flat tires to make them usable for this application. He seems particularly taken with the bi-stable mechanism he built for the kickstand, and we can’t blame him as we love seeing that kind of thing ourselves. The TPU seat is also a nice touch to keep with ‘everything printed’ vibe.
Now while the finished product does indeed fit into his suitcase, it needs to be completely disassembled. Well, unless you have an over-sized suitcase, perhaps. So our dreams of zooming away from the luggage line from the first paragraph were perhaps a bit premature. Still, from the footage at Prague Maker Faire at the end of the video, it looks like it was a fun enough ride that we can forgive [Ivan] for our overactive imaginations.
If you want an open-source e-bike, we’ve seen those too — but that won’t fit in any kind of suitcase.
