I had my first ride on one last night. Really, really cool little bike. It´s really fun with the angles and bigger wheels and I was having a lot of fun on my little local loop. It´s probably the most fun bike I´ve ridden in the last few years. I´ve got the Rallon and Occam AM too and it´s not a bike like those, i.e. a tool for a job, it´s just really, really, really fun. It´s exactly the bike for me over winter, something to forget about training and guiding and going fast and all that stuff, just for getting out on and laughing and playing.
Even sitting in the garage it just looks really special with it´s fat tyres and compact frame and the forks look so beefy on it for some reason.
Have you tried the 27+? I´m asking because they´re not that grippy in the mud. It´s something I´m really liking because they give a really stable, predictable slide but if you´re thinking that you will just be railing around with lots of grip on mud then it´s not that. They are probably grippiest in hardback or over roots etc. I´ve had no problems either but for aggressive riders in sharp rocks I´ve heard that the tyre sidewalls aren´t that strong yet. Just something to consider, for me it´s not going to be an issue given how I plan to ride this bike, i.e. having fun!
Anyway, it´s obviously early days in me and the Loki´s relationship but I can´t think of any reason why you shouldn´t buy one. Next thing I´m buying for mine is frame bags for a big backpacking adventure!
