Okay, so i've read a few threads on here and i know everyone says "You can't recommend a bike because everybody is different" etc. But I know literally nothing xD. Basically, i've done free running for about 3 years and i feel like i want to start something new. I chose this because (Please don't hate me for saying this or anything it's just my opinion) it's basically free running on a bike which sounds VERY appealing to me. However; I know virtually nothing about this sort of bike. I have my road bike for keeping my fitness up but that's as far as my knowledge goes. I don't want to spend a fortune purely because i'm not 100% sure i'll actually enjoy it, so i don't want to spend loads of money just to lose it when i have to sell the bike, i don't mind buying second hand though. I'm also a big guy at 6'4, so i'm not sure how that will go in any of this... So what i'm after is for someone to recommend me any bikes to look at or even places to look, but more importantly bikes/places/things i should definitely avoid.
Thanks in advance to anyone who replies
