Do yall know anything About These Bikes?

Me and my Father have owned these to Dynos for over 10 years; shit I couldn’t even tell you. For context my dad’s is the silver, mine is the green, we got them at separate times. Definitely after 2010 but before 2014 is the range we got them I believe. Mine was a gift of some sort and we built it with the authentic white Mags, Primo seat, and I believe handle bar grips all bought during that time frame (holy cow the price on those mags now 😯) . I went through a lot of tires as a kid as you can see w the mongoose tire, and I wanted to get rid of the front breaks and I think I tried to cut them off 🥲🥲 my dads from I remember he got as it sit. We think that mine (the green one) is a late 90s frame and my dad’s is early 2000s though we have no clue. What we found interesting about them later on down the line of ownership was the “D” on both of them resembles the other bikes colors. That had always made me interested about these bikes and to see if anyone knows any history!!!
