I have two numbers under my frame, can you help me understand which one is the frame number? Is it the same thing as serial number? And what is the other one? The make of the bike is Leader Fox, the two serial numbers I can read are DA2019292 and M1301617 (or MI301617 )
I want to register the bike on the website that helps in case it's stolen. Also, police would need this number too. So I only need some number that is unique within this bike model.

You did a good job in taking a screenshot of your codes as well, I will edit your question copying the serial numbers so internet will almost always find them ;)
