ICE say that the bolt needs to be secured with Loctite and torqued down to a
particular figure, which they'll be supplying along with the new bolt.

Not usre, coz it's 30 km away on the other side of a hill at the moment, but
I'm sure the nice men at ICE would tell you if you asked them nicely.

But there is no need or real inclination to do that on a 'bent, unless
of course you have a particular affinity for roadside ditches...

One of the things I see people having most trouble with when they first
try a recumbent is putting far too much (i.e., pretty much /any/) force
through the bars. All you need is fingertip steering force, even on a
hill start.

I know, which is why I suggested that it might only be a problem for a
few people rather than a design flaw.

I wonder if lending the machine to upright cyclists for a tryout would
place undue strain on the steering pivot.

With a USS, low seat height, trike, there is also the newbie tendency
to use the steering bars as a convenient place to both lower oneself
into the seat, and then lever oneself out again, which might apply
nasty bending loads to said pivot bolt
Not that I am accusing Legs of such misuse - I'm sure he has more
entertaining ways of abusing it!
