I've just signed up tonight and have been checking out various threads.
I'm a relative newbie to biking as well, my first two wheel bike ever was purchased three years ago. I started learning to ride at 33 !!!
Anyway, just wanted to say that the advice listed above is really cool. I appreciate you guys passing on riding techniques in such a friendly humble manner. Having struggled up hills myself, dropping the front by not getting the wheel over a log, losing the back by leaning too far forward, falling off, walking a few metres up the hill, getting back on, making some distance, dropping it again, but nearly clearing the next log... at the time it feels really embarrassing, but it's just practice, getting up and doing it again and each time you get further, you get fitter, your technique develops and then you are wondering why you struggled on that last hill, as you fall off the next steeper face just around the corner...
It's nice to hear riders pass on their knowledge in such an encouraging fashion.
I'm already glad that I signed up.
