These are actually both mine, but the orange one is the one I lend friends who are interested in trying out a fat bike.
The green one is actually really nice, and I find myself riding it a lot in the summer as well. So much traction, it's hard to transition back to my 29er (which about the same weight). But spinning up the wheels does take a lot more energy, and my pace is a bit slower on the fat bike overall.
