MTB RockRider 340 Btwin | Decathlon bike [Full HD]

Review and customize the beautiful Mountain bike cheap sold by Decathlon, and a short test drive with both sun and rain. I also use a smart band the Samsung Gear Fit to keep track of my workouts, it is very comfortable and lightweight waterproof and forwards!
