I got tired of not having a kickstand for my new fat bike, and sadly, because of the shape of fat bikes, not all kickstands work. I broke down, and decided to get one of these, and realized there were ones with 2 connection points. I figured it would be a more reliable mounting.
It was a little short between the connection clamps, so I had to put it on welding points, instead of the main body of the bars. Once I tightened it down though, it held firm. It attaches so securely, that it feels like a part of the bike. In fact, with the kickstand fully extended, I've sat on the bike, and put my weight on it, and it feels solid, like it would take a lot to break it, or make it fall off.
My bike has fallen occasionally, but with some experimenting, I learned that if the bike is heavy, and it's not on even ground, it can either drag the kickstand, or roll around it until it falls. It's not the kickstand, it's user error. This kickstand is better than good enough, if your bike falls, you most likely did something wrong.
I recommend setting the length of the kickstand so that the bike leans enough on it that the weight is spread out more evenly between it, and the wheels. Too long, and the bike won't lean enough to be stable, too short, and the bike might accidentally flop over it. You just have to experiment with your own bike.
