    Hub motor based e-bikes and Gear cassettes

    Hi guys, I had a question regarding e-bikes and Gears. And this is related to Hub motor based e-bikes and not Mid Drive systems. Usually in a normal cycle - we have a 7 speed or a 9 speed cassette at the back and a 3 speed cassette at the front. So that makes it a 7 * 3 = 21 speed gear system...
