Hi, I'm new to the forum but I've been looking at trial biking for a while I was just wondering whether anyone could answer a few questions I've got about it: 1) What actually is the difference between Trials and BMX? I know the difference between the bikes, but what do you do thats different? 2) How practical are they for riding around town? I have read that they have little to no gears, but are they usually high or low geared? and 3) How much would I be looking at for a decent but basic bike? What kind of size wheel is best for starting? Any advice would be great on any of this. Also I've noticed on many of the trials bike videos on youtube people seem to be riding what looks much more like a 'normal' mountain bike, are they actually very light mountain bikes, or just trials bikes which look like this? (e.g http://www.youtube.com/watch?v=mYIKfEU8yl8) So if anyone could answer any of my many questions it would be a real help thanks.
