Hey Mr B - you're misquoting me there!!! I think you got me and Cab mixed up!!
Possibly, sorry - I must have had an old quote tag in the clipboard and not re-copied.

It's just that you said somewhere, a road bike (inferred) is more stable than a 'bent, as it is higher. Whereas I'm preeeetty sure, that in theory, a 'bent should be more stable as it has a much lower centre of gravity.
The instability is therefore not the key issue, rather the difficulty in correcting instability. That was all!!
NO - you're either deliberately simplifying the physics analysis, or else you're too slow to keep up. I'm not sure which I suspect. But to reiterate it
again, an upright bike is easier to balance because you've got your weight on the pedals, and thus it's much easier to make adjustments by shifting your body left and right, e.g. if you start to topple left, you shift your weight right to counteract this.
Physics states that an object will topple if its centre of gravity is not directly above its base. With a bike, the 'base' of the object is the contact patch of the tyres - only an inch or two. Thus it doesn't really matter how high the centre of gravity is, its lateral position is the only thing that matters - and this is easier to adjust on an upright bike. Maybe I should be using the term 'easier to balance' rather than 'more stable', but this is essentially the crux of it.

Not having seen the TPT, I don't know.
Well, it's a trekking trail. i.e. it's for families. Hence, easy to ride.
Arch said:
If it was uneven, I would be more likely to worry about falling off, which might make me tense, and therefore less in control. I'm quite happy to admit that I'm not physically confident, and take a long time to learn any new physical skill involving the risk of a fall.
Don't get me wrong - the above is true of me aswell. Some days I can't ride for toffeem, like today, for instance - had a right mare today, but sometimes I really impress even my critical self.
It's just that your definition of 'uneven' is probably slightly different to my definition of 'uneven'. (But in turn my definition of 'uneven' will be completely different again to some other people's definition of 'uneven'.)
Arch said:
Firstly, when are the chances of falling off ever 'zero'?
When you're on a really easy trail. e.g. the TPT, when there's not really any serious obstacles or other vehicles/bikes.
Arch said:
Your logic is, as always twisted. I said (and I'm happy for him to tell me I'm wrong) that Cunobelin might be less experienced at off road than tarmac and percieve that he was more likely to have a spill.
That might be the case. But the reason for that perception might be due to the fact that he's riding a recumbent, not an upright bike.
Arch said:
You're saying, 'well, if he had taken to off-road (and was as experienced as you, bonj, are), his chances of falling off are zero'.
Well the point is if he's riding on easy terrain then the chances of falling off
should be zero - as they are on an upright bike. The point I'm trying to make is that they're only not zero because of the fact he's riding a recumbent, not a normal bike.
Arch said:
That's two different things - in my case, he's less experienced at off road, in yours, he's more experienced.
I don't know how experienced he is, probably best to wait till he offers up his own explanation.
Arch said:
Because it makes me feel more confident cornering at high speed
But surely if it's got three wheels you can't lean?
Arch said:
it allows me to crawl up big hills in a very very low gear.
Hmmm.. that's true I suppose, granted...
Cunobelin said:
I average 18 - 22 mph on a recumbent on road, way out of the performance specifiation of even a Snell certified helmet. Hence there is no point in wearing a helmet in these conditions.
that's a ridiculous stream of logic. Surely if you crash and you're wearing a helmet when you hit your head on something at 18mph, then you're going to be less injured than if you weren't wearing a helmet, even if it doesn't mitigate injury as well as the Snell performance criteria specify?
It's like saying there's no point wearing a seatbelt on the motorway because if you crash you're going to die anyway.
Cunobelin said:
As for the "technical trails" anyone who has done the TPT will inform you that it is not "smooth trails". We abandoned due to flooding and blockage. The moorland areas are muddy . slippery and you are unable to gauge what is in the puddles. Hence experienced or not one should recognise the risk and assess whether a helmet might help. I would have worn a helmet on these strtches on any of the bikes including the MTBs.
Hmmm....I still don't think it counts as 'technical' just 'cos it's a bit wet sometimes. But still, if you say that's why you wear a helmet then I believe you.
I still think your logic of thinking you're too fast for a helmet on road is ridiculous though.
Cab said:
Yet your counter argument is just batty. They're wrong because you say so. Give it a rest.
Recumbents have a flaw in that they're harder to balance, and this is why they're not as popular as normal bikes - but the people that have learnt to balance them or proponents otherwise seem to want to claim that it's because people aren't aware of them. I just think that's a fairly self-congratulatory viewpoint.
