Beginning with the integrated Specialized 1.2 E motor, the Turbo Vado proves itself as the ultimate city bike. The 1.2 E uses the same hardware as our 1.2 motor, but it features a tune that prioritizes efficiency. This means less peak torque and maximum output. Of course, it still features a near-silent operating design with our Custom Rx Street Tune that takes the output and makes it the most usable for an urban environment. Think of it this way: The more power you put out, the more power the motor puts out, and this makes accelerations from a standstill at, say, a traffic light both quick and efficient. The belt driven motor is also smooth, silent, and free of annoying vibrations.
