...Do all seats result in a sore bum/butt... if you cycle for 1hr? ...
This question is as old as, and has been asked of, I guess, ever since the invention of the bicycle. The short answer is that a bicycle saddle that one person finds satisfactory, is often compared by others, to an instrument of torture that could have been devised by Torquemada himself.
If there was 'one' (for those of us who suffer) we'd all be on it. Worldwide the nearest thing to the 'one' has traditionally been the heavy (as in very) Brooks leather saddle. Personally, I don't like them. Why? Because for them to 'work' properly you have to maintain them on a regular basis. Proofing and rubbing Neatsfoot oil in to it or somesuch. It's like another unrelated hobby in itself, puts me in mind of those who seek out the rarer varieties of 'real' ale - with all the funny names. Ignore the maintenance (particularly after exposure to a ride in the rain) and you're back to square one. Most people want less maintenance worries not more, hence the proliferation of 'maintenance-free' saddles. And hence the compromises begin.
However, before I go on to make a personal recommendation (personal remember , what works for me, may not work for you), I've highlighted your '1 hour' riding complaint for a reason. You shouldn't really be in such agony after one hour's ride, or at least it should not be such a level that it warrants a mention. Which leads me to draw two conclusions:
One) It's as Flecc suggests - you need more regular cycling to become used to the new position you're putting your body too; in other words - were you a cyclist before becoming an e-bike rider? If not, then Flecc's stay-with-it for now means it will probably fade as you become more accustomed to the saddle.
Or maybe it is Two) The saddle really is inadequate.
Before e-biking I was very paticular about my saddles, particularly as I would be off on tours where I'd be in the saddle all day, every day for at least a week or a fortnight at a time. And when not on holiday then on weekends it would still be a full day in the saddle. (Not so much of either these days).
So on getting my first e-bike I took one look at the 'disastrously' over-padded, 'poorly designed' cheap-as-chips saddle and immediately thought, "If I do nothing else - that saddle simply has to go!"
Imagine my surprise therefore when I found I had no issues with the saddle - whatsoever. I can only conclude that the added motor effect of the e-bike assistance meant that due to the reduced effort required on my part, I am not pulling and pushing as hard, an therefore giving my body an easier time of things. Either that or the limitations of the battery mean that I am not on it long enough in one ride for it to become a problem. That was 2008. The saddle remains to this day. However on my other 'normal' bikes, choice of saddle needs much more careful consideration and I have what
to me is now the ultimate saddle on them, (but not as mentioned, my e-bike which I find trouble-free).
So my recommendation for a comfortable saddle is - The Rido
It's cheapish about £13 when I first discovered them, (more nowadays,£20 with delivery on eBay) and so simple and plasticky-looking that it defies belief in the manufacturers claims to be one of the most comfortable saddles available.
A look on the customer letters page is staggering. People who had given up riding - now back in the saddle due to the Rido, etc., etc., And I too, have found it to be more comfortable than any previous saddle I have owned.
The RIDO bicycle saddle - get comfortable at long last!
