Fat bike always not so good. But if you want to ride in mountain area I think then it's ok. for the road riding, I don't think the fat bike will be the best choice.
Actually, the fat bike is an off-road bike that is the best fit for the hill area riding. I like the tires of the fat bike. When I was a newbie in cycling I was bought a fat bike for road riding! You may think I was a fool. may be. But I enjoyed this bike. Still, I would like to ride my fat bike. Thanks for the topic here.
