Looking for fast electric bikes? Propel has you covered. We carry many different types, most of which have a top speed of 28mph keeping with growing Class 3 definition of electric bikes or speed pedelecs. Some electric bikes go faster than 28mph, but we generally recommend against these. Most electric bikes are limited to 20 mph. Fast Electric Bicycles are the exception with a top speed of 28mph. If you want to go longer distances, keep up with traffic, or just simply enjoy going fast you should consider a fast electric bike.
