There is nothing quite like a session with your pair of in-line skates to break a sweat, but for those who want something different can always check out this interesting DIY project that has a pair of motorized Rollerblades as the end result. The blades themselves will feature an all-wheel drive complete with four hub motors. These motors will not restrain your blades in any way as there is minimal drivetrain drag, allowing you to use it normally. Being fully self-contained, you might think twice before performing tricks or doing grinds with a modified pair since it might ruin the set up due to all the external force subjected.
