How the ENVO ebike range calculator works
This free electric bike range calculator (also known as an ebike range estimator) is built for real routes, not a one-line formula. It simulates your trip along the road you enter, using the elevation along the route, and shows how much battery you will use and how much charge will remain when you arrive.
- Pick your ENVO ebike and battery. Choose from 12 models and a 48V 15Ah, 48V 17Ah or 48V dual (32Ah) battery.
- Describe the ride. Set rider and cargo weight, pedal assist level (PAS 1 to 5), your pedalling power, cruise speed and speed class.
- Set the conditions. Add the air temperature and any headwind.
- Enter your route. Add an origin, a destination, optional stops and round trip, then press Simulate Route.
You get a range estimate for your exact setup, your energy consumption in Wh/km, the elevation gain of the route and a battery remaining chart, so you can decide whether to charge first, change assist level or add a second battery.
What affects ebike range
- Assist level and speed. Higher assist and faster cruising draw more power from the battery.
- Rider and cargo weight. More mass means more energy to accelerate and climb.
- Hills. Climbing is the biggest energy cost on most routes.
- Headwind. Air resistance rises quickly with speed and wind.
- Temperature. Cold batteries deliver less usable energy.
- Tires and battery condition. Soft tires and an aging battery both cut range.
Battery size and ebike range
Battery capacity is measured in watt-hours: volts multiplied by amp-hours. Divide that by your consumption in Wh/km to get distance. The table shows what the three battery options in the calculator can cover at three typical consumption levels.
| Battery | Energy | 12 Wh/km flat, low assist | 18 Wh/km mixed terrain | 25 Wh/km hilly, high assist or headwind |
|---|---|---|---|---|
| 48V 15Ah | 720 Wh | 60 km | 40 km | 29 km |
| 48V 17Ah | 816 Wh | 68 km | 45 km | 33 km |
| 48V dual (32Ah) | 1,536 Wh | 128 km | 85 km | 61 km |
Illustration only. Real consumption depends on terrain, wind, speed, load and assist level. Run the simulator above for your own route.

eBike range calculator FAQ
How do I calculate ebike range?
Multiply battery voltage by amp-hours to get watt-hours (Wh), then divide by the watt-hours your bike uses per kilometre. A 48V 15Ah battery holds 720 Wh, so at 15 Wh/km it covers about 48 km. Real consumption changes with hills, wind, speed, load and assist level, which is why this calculator simulates your actual route instead of using one fixed number.
How accurate is this ebike range calculator?
It is a physics-based estimate. It models aerodynamic drag, rolling resistance, the climb along your route, motor and battery losses, your own pedalling power and the conditions you set. Treat the result as a planning estimate, not a guarantee. Tire pressure, riding style, battery age and stop-and-go traffic all move real-world range, so keep a 10 to 20 percent reserve.
How far can an ebike go on one charge?
It depends on battery size and how you ride. As a rough guide, a 720 Wh pack (48V 15Ah) covers around 30 to 60 km depending on assist level, terrain and load. The 1,536 Wh dual battery option holds more than double that energy. Run your own numbers in the calculator above for your bike and route.
What affects ebike range the most?
Assist level and speed, rider and cargo weight, hills, headwind, temperature, tire pressure and battery condition. Speed matters more than most riders expect because air resistance rises quickly as you go faster. Hills cost energy on the way up, and the calculator accounts for the elevation gain on your route.
Does cold weather reduce ebike range?
Yes. Lithium batteries deliver less usable energy when they are cold, and the effect becomes noticeable near or below freezing. Set the ambient temperature in the calculator to see how it changes your estimate. In winter, keep the battery indoors until you ride and avoid leaving it in a cold garage.
Why does cruising speed change range so much?
Aerodynamic drag grows with the square of speed, and the power needed to overcome it grows with the cube. Riding at 45 km/h therefore uses far more energy per kilometre than riding at 32 km/h. The calculator lets you compare both speed classes on the same route. Check the ebike rules where you ride before choosing a speed class.
Which ENVO ebikes can I simulate?
You can choose the D50, ST50, X50, Flex Overland, Lynx 20", Stax Pro, Stax DB, Flex Trike, Veemo SE, U50, D35 or ST35, then pick a battery configuration: 48V 15Ah, 48V 17Ah or 48V dual (32Ah).
How much range does a second battery add?
A second battery adds its full capacity to your total energy. In the calculator, the 48V dual (32Ah) option holds 1,536 Wh, more than double the 720 Wh of the single 48V 15Ah pack. The extra weight is small compared with the extra energy, so range grows by a similar proportion.
Can I plan a round trip or a route with stops?
Yes. Tick Round trip to simulate the return leg, or use Add Stop for multi-stop routes. The battery remaining chart shows where charge gets low, so you can plan a charging stop or bring a second battery.
How can I get more range from my ebike?
Use a lower assist level, hold a steady speed, keep tires properly inflated, pedal with more of your own power, carry less weight and choose a route with fewer steep climbs or less headwind. Avoid riding the battery down to zero and keep a reserve. Test each change in the calculator to see how much it is worth.
Is the ebike range calculator free?
Yes, the ENVO eBike Range Calculator and Trip Simulator is free to use.
