It's a corruption of YUF, meaning you useless fk except in this case referring to someone who also can't spel. Amusing urbandictionary.com/define.php?term=yuf
With @PeteH I'm really struggling to see an upright trike as a good idea. I know the English have a bizzarre love for the things, but to me trying to make an upright bike into a delta trike then go fast just seems like a disaster waiting to happen.
Getting a slightly broken Pete in and out of a low recumbent tadpole is probably not going to work, but the Kettweisel style "office chair over two rear wheels" style should be pretty do-able. For all that the recumbent world says they're slow, unweildy and generally not very good, compared to an upright they're the arachnid's elbows.
That's apparently 17kg, and if you can make it on and off a toilet it should be manageable.
There are higher-seat "recumbent" delta trikes out there, but obviously the higher up you go the uglier corners become. I haven't seen any 622 wheel versions, I suspect because the wheels are hard to build if you expect recumbent performance rather than upright trike behaviour (where the high centre of gravity limits how hard you can corner, so the wheels have to be strong, but not too strong).
@Criggie yeah, there's a whole racing scene in the UK for those things. If he wants one, Pete is in just about the only country where they're reasonably available.
One advatage of the recumbent ones is that you can usually fold the seat back flat and lean the whole thing on a wall, so they don't use huge amounts of storage space (unlike, say, load bikes)
At one stage I had four rickshaws in a nearly double length garage, and it was full.
"classic cruiser"... looks more like an old-fashioned "ladies" bike to me, no cruiser about it. But hey, for $300 who's complaining about the description :) Wait and complain about the quality instead.
