Good job! Congratulations.

' sure its aluminum not steel?

If you must get a kickstand, get the one that mounts at the back.

That way you can roll your bike forward while its deployed if you have to. But I would get a bike lock and/or a rear rack first before I get a kickstand, but that just me.

Have a safe and joyful ride!
