Is the top speed, motor power or gearing. Question would a higher gear give more speed?? and is that high gear suitable for hill at 8kph, one gear only has limitations, example a low gear with a top speed of 8 kph would pull up a steep hill no pedals, a high gear might do more tha 27kph in easy going circumstances. A change and choice of gears is a great value, rarther than just a single gear.
