Methodology & References
Our calculators use physics-based models tuned for upright, fat-tire e-bikes ridden in the U.S. We account for rider+bike weight, grade, rolling resistance, aerodynamics, drivetrain efficiency, and realistic wind assumptions. Results reflect steady-state performance on paved surfaces.
- Hill Climb: balances gravitational, rolling and aerodynamic forces to estimate max steady speed and energy use.
- Range: models Wh/mile across speed, terrain and weight to estimate practical range—not lab figures.
- Charge Time & Cost: uses pack Wh, charger amperage and local kWh rates for the U.S.

Tools FAQ
How accurate are the e-bike range and hill-climb results?
They’re physics-based estimates that account for weight, grade, rolling resistance, aerodynamics, and drivetrain efficiency. Real results vary with wind, tire pressure, road surface, and rider effort.
What can I do with the Ariel Rider e-bike calculators?
Use our tools to estimate hill-climb speed, real-world range, battery charge time & cost, CO₂ savings vs. car, and ownership savings. Each calculator is tuned for U.S. riding and Ariel Rider models.
What hill grade counts as “steep” for an e-bike in the U.S.?
Around 10–12% is steep for street riding; 15%+ is very steep and will slow most e-bikes unless you use higher assist or throttle. Our Hill Climb Estimator shows your max steady speed by grade.
How do I measure my local hill grade for the calculator?
Use a map/elevation tool or measure rise ÷ run × 100. On the estimator, try presets (5%, 10%, 15%, 20%) for common U.S. streets and steep city hills like San Francisco or Seattle.
What affects real-world e-bike range the most?
Speed (aero drag), total weight (rider + cargo), terrain (hills), surface, wind, and tire pressure. Our Range Calculator models Wh/mi so you get practical miles per charge.
How do I estimate battery charge time and electricity cost at home?
Enter your battery Wh and charger amps in the Charge Time & Cost tool. For cost, use your local ¢/kWh (see your utility bill). It outputs hours to full and estimated charge cost.
How much can I save riding an e-bike vs. a car?
Use E-Bike vs. Car Savings to compare fuel, maintenance, parking, and typical miles per year. Many riders see a clear break-even in months, then ongoing annual savings.
Do U.S. e-bike state rebates stack with other incentives?
Often, state or city rebates can combine with federal or utility programs when available. Check our E-Bike State Rebates & Tax Credits (US) tool for current eligibility and links to apply.
Can I embed these e-bike calculators on my website or blog?
Yes—use the Embed our tools section to copy an iframe for a specific calculator (range, hills, CO₂, charge time, savings). It’s lightweight, mobile-friendly, and includes attribution.
Which Ariel Rider model should I use in the calculators?
Pick your model (or use presets), then adjust rider weight, terrain, and mode. The tools are Ariel Rider–tuned so you can test real U.S. scenarios—commutes, steep streets, cargo, or performance rides.
