I have my mongoose dolomite mountain bike, it has a few modifications to it, I swapped out the handle bars from the factory straight bar to a pair of UMI racing bmx grips because I’m tall. After the handle bar swap I repositioned the hand brakes to a more unique spot. I also swapped out the seat to a more comfortable Schwinn air cushion. The only flaw about this bike is the gears, I have it permanently set to a mid gear so it’s not the lightest or the heaviest, but other than that Everything works and it’s ready to roll I just have no time to ride it anymore do to work. I can deliver as well but only for full price!
