...SORRY ABOUT MISSING THE ORIGINAL SOUND! THE REASON, YOUTUBE EXPLAIN ME THAT I'VE NOT THE COPYRIGHT OF MY OWN MUSIC... :o( #5 THE ULTIMATE BIKE IS READY! .....UNLIMITED RANGE AND 100% ECO-FRIENDLY POWERED!

To speedup I need only a very short time, but here the problem, to speedup without a "burn out"! I'd programmed the ideal value now. For a quick slow down I have 2x 210mm Magura hydraulic disc brakes in the front and for a soft slow down the motor recuperation in the back ...
