Pros Mid drive systems are known for being able to climb long steep hills because they can leverage the lower gears of the bike and keep their rpm’s in an efficient range without getting "bogged down" like a hub motor. This is a good feature if you ride in areas that have consistently long and steep climbs. These motors can also leverage the higher gears of the drivetrain to cruise along at high speeds on the flat or inclined roads. Since the motor is at the cranks of the bike it provides for a low and centered weight distribution. If the battery is mounted in the center of the bike that further adds to great weight distribution which is good for the handling of the bike as well as making it easier to lift onto a car rack or carry up stairs. Most mid drive systems use a chain, cogs, and derailleur drivetrain. Some systems are compatible with internally geared hubs and belt drives. Most of the popular mid drives systems are only available on complete e-bikes with specific frame mounts. There are not many retro-fit mid drive kits to choose from right now but it seems that there may be more on the horizon.
