Vado: it means \"I go.\" Cruising past traffic at up to 28 mph and arriving faster to work than your coworkers, all while still having time to stop for coffee. It also means riding your bike way more often than you ever thought you would, explore, get fit, do your thing, Vado SL eliminates the barriers that had your old bike collecting dust. SL: it means \"Super Light.\"At 40% lighter than the average e-Bike, that means carrying Vado SL up a flight of stairs, lifting it onto the train or bus, or dropping it onto a bike rack without breaking a sweat and without throwing out your back. SL means livable. Vado SL delivers the defining combination of weight, power, range, and ride quality, giving you the confidence to ride more often and to places that you never imagined you would.
