What is the difference between a mid-drive and hub motor e-bike?

Mid-drive motors sit at the cranks and leverage your gears, providing better hill climbing and more natural ride feel. Hub motors are in the wheel (usually rear) — simpler, cheaper, and lower maintenance. Mid-drive excels for hilly terrain and off-road; hub motors work well for flat commutes. Mid-drives cost $500-1500 more on average.
