Welcome to the forum, Leo. We're glad you've joined us.
You've done well on your first motorized bicycle project. Congratulations.
Just a suggestion, and maybe it rides good as is but, knobby tires will give you a less smooth ride. You might want to consider a smooth tread at some point in the future.
If you could match that chartreuse color you might consider adding some accent stripes or a 'swish' on the fuel tank and chain guard. That would really set it off. The color combination looks good. It is an eye catcher for sure.
Have fun and ride safe.
