Ebike Range Calculator

“How far will it go on one charge?” is the first question every e-bike buyer asks — and the honest answer is “it depends.” This e-bike range calculator turns that vague answer into a usable estimate by combining your battery capacity, assist level, terrain, and rider weight into a realistic distance band in kilometers or miles.

How Range Is Estimated

Range comes down to one ratio: how much energy your battery holds divided by how much energy you burn per kilometer.

We reserve about 10% of the battery (most systems never fully drain) and adjust energy use for how hard the motor works, how hilly the route is, and how much total weight it has to move.

The Big Levers

• Battery capacity (Wh): the headline number. A 500 Wh battery holds roughly twice the energy of a 250 Wh one.
• Assist level: Turbo can drain a battery three times faster than Eco. This is the single biggest thing you control.
• Terrain: constant climbing can cut range by a third or more versus flat ground.
• Rider + cargo weight: more mass means more energy to accelerate and climb.

Typical Range Reference (500 Wh, rolling terrain)

Stretching Your Range

• Drop to a lower assist level on flats and descents — you barely need the motor there.
• Keep tires inflated to the recommended pressure; soft tires waste energy.
• Pedal smoothly and maintain momentum rather than stopping and starting hard.
• In cold weather, keep the battery warm before riding — cold cells deliver less.

Disclaimer: These are estimates only. Real-world range varies widely with wind, temperature, stop-start traffic, motor efficiency, and battery age. Treat the figure as a planning guide, not a guarantee, and always carry a buffer for the ride home.
