Chemistry determines the cell voltage (1.2V or 1.5V and there are others like Lithium at 3.0V), whether the battery is rechargeable, and how the voltage changes as the battery discharges i.e. at what voltage is the battery considered to be flat or fully charged. Switched mode power supplies. One more point.
The Average Bike Riding Speed. The average road bike speed is between 11 and 12 mph. Bike riding speeds vary widely depending on your riding conditions. When you are zooming down a paved hill, your speed may increase to over 20 mph, while you may slow to only a few miles per hour when you are climbing a steep or rocky grade.
Distance covered. Average speed varies to an extent with distance covered. Rides less than an hour or so in length will usually have a slightly lower average, because the first part of a ride is slower as your legs warm up. Rides between one and two hours usually have the greatest overall speed.Then for longer rides the average will often start to fall slightly, as fatigue plays an increasing role. For many of us rides over about three hours can become very tiring (assuming a reasonable sustained effort during those three hours!).ides between one and two hours usually have the greatest overall speed.
