Bike Of The Day: Sebastian’s GT Speed Series ProXL Cruiser

Today’s Bike Of The Day is a beautiful custom GT Speed Series ProXL 24″ Cruiser sent in by Sebastian Tiefenthaler out of Germany. I love the custom colorway on this build. Be sure to give this bike a rating via the sliders below for the December Bike Of The Month and the 2020 Bike Of The Year.

Hi my name is Sebastian, I´m 34 and from Bavaria Germany. I started BMX again last year after a 22 year hiatus. So I bought the GT Speed Series ProXL Cruiser 2020 and thought to myself that I just have to make something unique out of it. Did the paint job all by myself with the awesome paint from Spray.Bike. For the color scheme, I was inspired by the 2013 GT Jersey and I love this color combo.Check out my Instagram for my other builds:  diafei_unique
