Why is my Commuter 5 e-bike getting much less range than advertised (35 to 60 miles), and could the battery be faulty?

Range under the advertised 35 to 60 miles is usually caused by riding conditions or bike setup, not a faulty battery. Common causes:

• Cold weather: Cold can reduce range by 20 to 30 percent because the battery puts out less power when it is cold.

• Low tire pressure: Low pressure makes the motor work harder. The Commuter 5 should be at 40 to 50 psi, which is printed on the side of the tire.

• High assist level and heavy throttle use: These drain the battery quickly. Ride in assist 2 most of the time and save higher levels for hills.

• Battery reading accuracy: Once a month, run the battery down until it is low, then charge it fully. This keeps the battery reading accurate.

If range is still well below expected after a couple of weeks of these changes, contact support so the battery can be checked.
