Hi  I'm a newbie to the site and to purpose built trials bikes - can I introduce myself and scab a couple of bits of advice, please?  I used to ride trials-style on an old 27inch wheel beast back in the late 70's - around Adle Woods in Leeds - anyone ride there now?  I've been on the dark side (riding motorbikes) since, including a trip to the end of the Earth and back.  Try riding across Mongolia, two-up on road tyres!  Have a look at:  www.sorebums.net  I swear it's not a porn site - LOL.  Now I'm looking to return to the fun of riding pedal-powered trials, and drag my young kids into it too.  Can you point me in the right direction?    How do I get to ride a few bikes to see what suits me?  I live in Manchester.  What should I buy?    Where from?  I weigh 90+kilos, so I guess I'll need something strong (with strong brakes).  Any pointers?  Thanks in advance.  Simon
