A mid-drive motor "powers the cranks and sends force through the drivetrain in the same way your own legs would move it with added assistance" creating an intuitive riding experience. These motors provide "optimal power transfer and torque, resulting in a smoother and more natural ride feel" which many experienced cyclists prefer.
Hub Motors
Integrated into either the front or rear wheel hub, these motors directly drive the wheel rotation.
Advantages:
- Generally more affordable
- Simpler design with fewer moving parts
- Less drivetrain wear
- Often easier to maintain
- Can sometimes include regenerative braking
Disadvantages:
- Weight concentrated in one wheel, affecting handling
- Cannot leverage the bike's gearing system
- Less efficient on hills
- Can make wheel removal/flat repair more complex
Hub motors "move the wheel forward through a motor driven in the wheel itself" and are valued for their simplicity and reliability. They are "known for their affordability and simpler maintenance, making them an excellent choice for those on a budget or new to e-biking" though they may struggle with varied terrain.
Battery Technology and Range
Battery technology continues to evolve rapidly, with significant implications for e-bike performance, range, and usability.
Battery Capacity and Range
Battery capacity, measured in watt-hours (Wh), is the primary determinant of range. Modern e-bikes typically feature batteries ranging from 250Wh to 800Wh, with higher-end models pushing beyond.
The range you can expect depends on numerous factors:
