Bicycle made for Three

It was a Trandem as made popular by the goodies in the 70's.

Triplet? I like this one, but I'm going to have to have another kid if I
want to buy one ;-)

I dunno, but the other day I was thinking that if you made a 3 man bike, and
all three riders were of similar weight and strength, and you got the pedals
lined up right, you'd have a perfectly balanced bike, in the same way as a
straight 6 engine is perfectly balanced. I hope someone knows what I mean
😄.

Leg analogue is a two-stoke engine, not a four-stroke. Think again...

Not sure about that, but if you had riders who didn't mind, you could
set the pedals up with a 180degree difference between them and keep the
bike under continuous force. Was this what you were thinking?

90 degree difference, Jon. And I suspect he was thinking 60 degrees. I'm
sure both these solutions have been tried. I expect they don't work
very well on bicycle tandems, because each rider is all the time
putting stress on the bike in different ways which will both put
additional stress on the frame and make it more difficult for the
riders to get in rhythm. I'm prepared to be wrong on this, however.

Out of phase is generally kinder to the drive train.

On a tandem, some people do 90 deg. out of sync for this reason. Others
can't get used to it (as you surmise, it just feels wrong.). Quite a few (us
included) have it set up a little bit out of phase (couple of teeth or so)
as it feels better. I can't remember who goes first.

With adults on triplets and longer, it's recommended to be at least a bit
out of phase, if not completely, since otherwise you're in danger of
breaking things (eg freewheels/hubs).

I can't remember whether older wobbly tandems are more or less amenable to
out of phase than modern stiff ones, if at all. (relevant to your stress
idea).

cheers,
clive

They used to use triplets for pacing in races sometimes.

There is indeed. It was a triplet, and probably a horn Me'n'U2 which
apperas to be the most popular triplet about. Whereabout were you in the
world?

120 degree actually. Got there in the end. (Given my work with 3 phase
electricity, it really shouldn't have taken that long!) :-)

I would expect it to smooth out the stress on the frame and components
as rather than two high peaks of energy per revolution, there would be
six evenly spaced, lesser ones.

I suspect that the riders might be the problem, but it shouldn't be
outside the realm of practice.

Was thinking balanced as in vibration / oscillation free. With a straight 6,
as one of your moving parts is travelling down, there's another moving up.
The end result is spot on end to end balance. On a bike, it'd be side to
side balance I suppose.

It's a triplet. Not a "tridem", puh-lease.

Trandem. Unless you're trying to imply that the Goodies weren't
infallible, you cur.

They certainly did, in the days before Derny pacing took off; tracks
had teams of pacers on triplets (and even quads sometimes), which were
considered worthy of publicity in their own right - at one time Dunlop
Tyres provided comprehensive sponsorship to such teams.
