This is one of the people/teams competing for an innovation prize at #Spezi2026. A recumbent trike you can make mostly from wood. “Open source” (I put it in quotes because I know definitions vary and I’m not clear which one this uses).
I’m told the cost was about 1,200, but that is a lot less than a similar recumbent trike with a metal welded frame would cost for materials (not to mention the labor time, skills).
Front wheel drive and the whole rear moves with the handlebars.
“Based on a concept invented more than 10 years ago by two brothers, the moskitOS tilts and turns thanks to the clever use of an articulated trapeze that allows the whole front section, including the rider, to lean when cornering! This solution also has the advantage of driving the front wheel directly, avoiding the classic long transmission chain used on almost all similar vehicles.”

When the pedals are ahead of the front tire, it becomes a Bullpup Trike
I like the idea. But why does it cost 1200,- dollars? I mean wood and metal is not THAT expensive.
Looks like that’s the Bill-of-Materials if an individual sources the exact parts they specify at retail. That’s without including the value of the tools one would need to own already, plus skills with said tools, and time
Basically, a BoM is used in the DIY space to give one a realistic idea of what a project will cost them “at a minimum” - it’s not a “with profit for us” “price”, it’s a “don’t go into this half-assed and come after/bash us months/years later for mis-leading you about what’s possible with fuck-all for skills, resources, or perseverance”.
I would like to think I could get it done much cheaper, in the way a shade-tree mechanic can keep an absolute piece-of-trash on the road for years, but won’t sell or recommend it to a friend, but even more-so, I would rather spend the time and resources making something I could be proud to pass-on to a beloved family-member or best-friend, so “$1200” is the minimum figure I’m going to use when deciding whether to commit to this project.
I don’t know where those numbers came from, tbh. A year ago they had some CNC wood kits that cost € 170
Ah, thanks for the clarification. 170,- € sounds good :)
Does it run Linux or something?
Open Source can also imply “Off-the-Shelf” parts, in the same way IBM made their Personal Computer with parts that were already on the market from other manufacturers.
I think it’s more, like, “open hardware” (partially open). By the way, to be fair, the post itself says:
“Open source” (I put it in quotes because I know definitions vary and I’m not clear which one this uses)
UPDATE: actually they have an explicit license, the “CERN Open Hardware Licence Version 2 - Weakly Reciprocal” https://gitlab.com/ohwr/project/cernohl/-/wikis/uploads/82b567f43ce515395f7ddbfbad7a8806/cern_ohl_w_v2.txt
Ohhhh Open Source is the OS. Wow I’m dumb.
Yeah I read it as Operating System too.
I think it’s also a play on words. MoskitOS > mosquitos
Ah, you were paying attention to the “OS” part of the name! Now I get it. I think you’re right.
