I don't know much about kickstands. My bike doesn't even have one. I lean it up against the wall in my house. A guy on endless-sphere.com forum recommended this one.. He said it worked on his electric bike. It may not work on yours, though.

This page shows about 4 or 5 of them. He used the double leg, screw adjust one. It comes in black or silver.

You might be able to find a decent kickstand at a bikeshop near where you live. Might be better doing it that way. Or a scooter shop. I don't know how they install because I don't have much experience with them.

if You want, you can take a picture of your bike frame where the kickstand is and go on this forum and ask them, I bet someone will know exactly which one will work for you.

Or maybe you could e-mail crowcycleco and ask them.
