Personally i would stay away from the saracen if you seriously want to get into trials then get a proper perpose built bike. The dirt jump type bike you are looking at will be heavy and not really suited to trials. also trials bikes are really a one purpose bike you can't really get one that you can just drop the seat and ride. I would look at buying a second hand bike like a onza t-pro which i think is a great bike to get into the sport. Hope this has helped.
