Tools for your next e-bike decision.
Updated
Planning calculations and dated source summaries, with their assumptions and limits visible. Start with the question you need to answer.
How much battery?
Estimate nominal watt-hours and amp-hours from distance, consumption and reserve.
02 / OWNERSHIPWhat will it cost?
Bring purchase, resale, electricity and running costs into one planning estimate.
Read alongside your calculation
Results depend on your assumptions. They are planning estimates, not guaranteed range, savings or physical battery compatibility.
Maintenance intervals
Enter the service intervals from your own manuals.
Open the maintenance plannerWhat does a charge cost?
Model partial charges with your own variable electricity rate and efficiency.
Open the charging-cost calculatorChoosing a bike? Browse verified specification records alongside these planning tools.
What could a bike commute save?
Compare actually avoided car or transit costs with bike costs, and see the boundaries of an operational CO₂ estimate.
Open the commute savings calculatorCan this battery travel?
Check rated Wh, device category, condition and transport context against sourced U.S. capacity bands.
Open the battery transport checkerWhich rebate terms apply locally?
Filter selected dated programmes by location and benefit type, with closed and unconfirmed offers clearly separated.
Open the rebate finderHow far could this energy take me?
Use your measured Wh/km or explore explicit ride assumptions, with sensitivity arithmetic and a visible reserve.
Open the range estimatorWhich e-bike rules apply to a jurisdiction?
Read dated device, rider and route summaries, starting with Washington State. Uncovered locations have no inferred limits.
Open the law finderWhich size should I test ride?
Compare body measurements with exact published configurations, review missing guidance and explore Gazelle’s scoped frame-size formula.
Open the frame-size and fit calculatorWhat energy could a charging stop add?
Calculate battery-side energy from your stated capacity and charge change, with optional charger-efficiency and usable-source assumptions. Time stays unknown unless you confirm a comparable observed rate.
