Here is what i built: it is more of a 2 wheel extension as the top part is my normal unicycle but screwed in. it seems pretty solid. i have only ridden about 2 revolutions so far but i think its more confidence holding me back, as its pretty high at 2m. Anyone have any tips specific for learning a 3 wheeler or is it basically the same as trying to learn a normal one?
Same as a giraffe really. Just go for it. Dont worry about falling you’re not really that high off the round. It seems really high but your feet are only about a meter off the ground.
Very nice!
wouldn´t that be very tough on the bearing holders?
The two lower wheels should twist and bend them pretty good.
no it doesn’t, well not so far. I got the idea off those ‘extension kits’ you can buy, and i geuss if it wroks for them…
HELMET!!! geez…
Well… I don’t know, those branches don’t look very dangerous at all. Quite soft and bendy, in fact. 
yes, but that ground looks a little bit hard. his choice though (:
Now let me get this straight - you’re suggesting helmets should be worn just in case you fall off??!!??
In my experience, wrist guards are 10X more important than helmets for Tall unis.
Edit: I’m not saying that helmets aren’t important. I’m just saying that in an hour of riding, I fall and bend my wrists back about 20 times, and only hit my head about twice.
Apologies, Callum. Massive threadjack off into the rough ground of helmet wearing.
Getting back on track…
The 3 wheeler looks great! How do you decide where the hubs go on the frame to ensure decent grip between wheels? How about tyre pressure?
bah, there we go. Tempted again. I think if my old uni survives my girlfriend learning (shouldn’t be a tough job - she’s tiny :)) then I shall make it into a two-wheeler. heheheheh.
Dude, spray paint the bottom two wheels and the lower frame green and film yourself on a greenscreen. then put the film in a greenscreen program and you’ll be flying!!!
So, would you call that a bike and a half?
no, see bikes have two wheels. three wheeled things are called trikes 
specifically this is a triverticycle, at least that is what I think it should be called.
now you can ride around and ask the bikers where their other wheel is
