Bobington07

I started mountain biking earlier this year and love it. Really interested in starting out trials as well, is there any reason not to try learning both at the same time? Definitely made a lot of progress since I started riding, but still got a long way to go. Not sure if I might be better concentrating my time on one first. Seen this bike though for what I think is a good price, any advice regarding it? I know if I get a trials bike I'd want a saddle and so far only seen Inspired and Onza with them. https://www.gumtree.com/p/bicycles/onza-zoot-trials-bike/1187940952
