On the Ejoe website, the image looks like your bike comes with a single leg kickstand, which shouldn't be dragging. If not, are you dealing with a double leg kickstand that has a pivot hinge that hangs down from the bottom of the bike ? If that's the issue, consider switching to an ESGE scissor leg double kickstand, then you get the advantage of the double legs, but they're out of the way when up.
Hi @austin tao , the Esge kickstand is available at many local bikeshops and if you don't find it there, it is sold online. If possible, choose the Esge that will allow you to trim the leg length, since the standard Esge double stand is designed for a 26/700C size wheel. Even the standard kickstand can be shortened (carefully! with a vice and hacksaw ) remember to measure twice and cut once.
