e-MTB Battery Size Guide: 400Wh vs 600Wh vs 800Wh

How much e-MTB battery do you need? Compare 400Wh, 600Wh and 800Wh batteries, what affects real-world range, and tips to ride further on every charge.

Battery capacity, measured in watt-hours (Wh), decides how far an e-MTB can take you on a charge. But bigger is not automatically better: a larger battery adds weight, and the motor, terrain, rider weight and assist mode all affect real-world range. Here is how to pick the right size.

Battery sizes on today’s e-MTBs

What affects real-world range

  • Assist mode: riding in the highest mode can drain a battery several times faster than an eco mode.
  • Climbing: elevation gain uses far more energy than distance on flat ground.
  • Rider and gear weight: heavier loads mean more work for the motor.
  • Motor power: high-torque motors deliver more help, and use more energy to do it.
  • Temperature: lithium batteries give less range in the cold.

Which size is right for you?

400 to 420 Wh: lightweight and nimble

Ideal if you like to pedal and ride for two to three hours at a time. Bikes like the Pivot Shuttle SL/AM and Orbea Rise SL accept range extenders (250 Wh and 210 Wh respectively), so you can add capacity only when you need it.

600 Wh: the middle ground

A good balance of weight and range. The Cannondale Moterra SL 2 pairs a 601 Wh battery with a Shimano EP801 motor.

800 Wh and up: big days and big climbs

For long rides, lots of elevation or riders who want maximum assistance. The Specialized Turbo Levo 4 Expert (840 Wh) and the Pivot Shuttle AM (800 Wh) are built for this. The Pivot Shuttle AMP’d adds 12 A fast charging, reaching 80 percent in about 90 minutes.

Tips to get more range

  1. Use a lower assist mode on flat and rolling sections.
  2. Shift gears to keep a steady, comfortable cadence.
  3. Keep tires at the right pressure.
  4. Store and charge the battery at room temperature.
  5. Carry a range extender on big days, if your bike supports one.

Frequently asked questions

How far can an 800 Wh e-MTB go?

It depends heavily on terrain, mode and rider weight. On mixed trails in a medium mode, an 800 Wh battery typically covers a long day of riding. Steep climbing in the top mode shortens that considerably.

Is a range extender worth it?

On a lightweight e-MTB, yes, if you sometimes ride longer than usual. You carry the extra weight only when you need it.
