E-bike range calculator
Get accurate estimates based on battery capacity, motor power, terrain, wind conditions, rider load, and more.
How it works
Step-by-step guide to using our e-bike range calculator
Input your e-bike's battery capacity in watt-hours (Wh). This is usually found in your bike's specifications or on the battery label.
Enter your motor's maximum power output in watts (W). Common values range from 250W to 1000W+.
Enter your weight and your bike's weight. If you're carrying cargo or a trailer, include those weights as well.
Upload a GPX file of your planned route for the most accurate range calculation. The calculator will analyze elevation changes and terrain.
Adjust speed, wind conditions, pedaling assistance level, and other factors that affect range.
Click calculate to get your estimated range, battery consumption breakdown, and route analysis.
Features
Our calculator uses real physics equations to account for drag, rolling resistance, gravitational forces, and motor efficiency.
Upload GPX files to analyze elevation profiles and get route-specific range estimates.
Accounts for wind speed, wind direction, rider weight, bike weight, cargo, speed, and terrain.
Include solar panel calculations for extended-range planning.
The full calculator and analysis workflow are available without a paid plan.
E-bike range is the distance your electric bicycle can travel on a single battery charge. Unlike traditional bicycles, e-bikes have a limited range determined primarily by battery capacity and energy consumption. Understanding your e-bike's range is crucial for planning trips, commuting, and avoiding being stranded with a dead battery.
Battery capacity, measured in watt-hours (Wh), is the most important factor determining range. Larger batteries store more energy and provide longer range. Common e-bike batteries range from 250Wh (entry-level) to 1000Wh+ (high-end touring bikes). A 500Wh battery typically provides 40-100 km of range depending on other factors.
Motor power (measured in watts) affects both performance and range. More powerful motors provide better acceleration and hill-climbing ability but consume more energy. Motor efficiency also matters—modern mid-drive motors are typically 80-90% efficient, while hub motors range from 70-85% efficient.
Speed has a significant impact on range due to aerodynamic drag, which increases with the square of speed. Riding at 25 km/h may provide 80 km of range, while riding at 35 km/h might only provide 50 km. Our calculator accounts for this non-linear relationship.
Hills and elevation changes dramatically affect range. Climbing requires significant energy, while descending can provide regenerative braking (on some models). A route with 500m of elevation gain will consume much more battery than a flat route of the same distance.
Total weight (rider + bike + cargo) directly impacts energy consumption. Heavier loads require more energy to accelerate and climb hills. A 20kg difference in total weight can reduce range by 15-25%.
Headwinds significantly increase energy consumption, while tailwinds can extend range. A 20 km/h headwind can reduce range by 20-30%, while a tailwind can extend it by 10-15%.
The level of pedaling assistance you provide affects range. More pedaling means less motor power needed, extending range. Eco mode with active pedaling can extend range by 30-50% compared to throttle-only or maximum assist modes.
Our e-bike range calculator is the most comprehensive tool available for estimating electric bike range. Simply enter your bike's specifications, upload a GPX route file (optional), and adjust riding conditions to get accurate range estimates.
The calculator provides detailed breakdowns of energy consumption, battery usage per segment, and recommendations for optimizing your route, including advanced analytics, solar power calculations, and detailed efficiency metrics.
