Today’s Bike Of The Day is a special one! It’s a Standard 125r with a twin top tube!! Not only does it have a twin top tube, it’s also an OS20! I got to see it in person a few days ago at the State Championship Qualifier at Bethel BMX and it looks amazing in person. Big shout out to Mark Wierzbieki for submitting this awesome bike!
Be sure to give it a rating for the Bike Of The Month and Bike Of The Year charts

I wanted something that made people stop and look and wonder what it was.. Most people think it’s a cruiser from far next to a 20” then second guess it up close with its twin top tube. I had the geometry tweaked alil for my liking.. I truthfully built something that I’d never sell with its custom serial. Bike rides very smooth and most don’t notice the shorted backend.. ultimately it’s a park bike rear with race gearing and disk brake and 22” ttt race front end. ~Mark Wierzbicki
