Reject this fit when
One failed gate outweighs the range estimate
Reject a commuter whose battery only passes under ideal conditions or whose weight cannot be managed through the real storage and transit routine.

Electric Bike Range Calculator
Estimate a conservative range, calculate the battery capacity your round trip requires, and continue to the buyer guide that fits your real use. The output is a planning aid—not a manufacturer promise.
Your planning result
32–46 miles
Keep roughly 8 miles as an additional route reserve until you know the bike, battery, and conditions. Tire pressure, stop frequency, speed, battery age, rider input, surface, and temperature can materially change the result.
Battery passes this planning gate300 Wh minimumThe selected battery has about 200 Wh of modeled headroom. Compare a commonly available 400 Wh-or-larger configuration and verify the exact listing.
From estimate to shortlist
Start with commuter electric bikes
Prioritize efficient tires, dependable brakes, lights, fenders, rack compatibility, and a removable battery that can cover the round trip with reserve.
Battery target400 Wh or largerThis is the nearest practical shopping target above the modeled 300 Wh minimum: a compact battery. More capacity adds weight and cost, so verify the exact route need.

- Battery watt-hours—not only volts or amp-hours
- Electrical-system certification language
- Correct charger and replacement-battery path
- Total payload and rack or passenger limits
- Warranty owner, return freight, and local service
Support boundary
Buy and get support from the seller
Prices, inventory, specifications, warranties, returns, repairs, batteries, chargers, and product support must be confirmed with the retailer or manufacturer responsible for the exact bike.
How to use this estimate
Enter watt-hours when available. If the battery label shows volts and amp-hours, multiply them to estimate watt-hours. Example: 48 volts × 10 amp-hours = 480 watt-hours. Use total rider-plus-cargo load, then choose the conditions closest to the hardest normal leg.
Planning ruleIf the required round trip sits near the top of the estimate, the system is undersized until a real ride proves otherwise. Do not spend the reserve during routine planning.
Electric bike range questions
How many watt-hours does an electric bike need?
There is no universal number. The calculator estimates a minimum from the trip, combined load, terrain, assist demand, weather, and desired reserve. Use the recommended shopping target as a screening gate, then verify the exact battery and route.
Should I buy the largest battery available?
Not automatically. Extra capacity can add price and weight. Buy enough documented capacity for the hardest repeat trip with reserve, while keeping the complete bike manageable and serviceable.
Why is this estimate lower than an advertised range?
Maximum-range claims may rely on lighter loads, low assistance, moderate speeds, flat terrain, warm weather, and ideal tire pressure. This calculator deliberately uses a planning range and exposes conditions that can consume reserve.
