Decision Lantern

Outdoor calculator

E-bike range estimator

Reviewed Skip to the planner

Riders matching a battery pack to a commuting distance. The decision this page isolates is narrow on purpose: estimate a watt-hour class from miles and hills. Capacity, season, and packed size are the published facts that survive a weekend trip.

This page produces an explainable category or size so options can be compared without a product ranking. The calculator does not rank Aventon, Rad Power Bikes, and Specialized. It produces an explainable class so Aventon Level 2, Rad Power RadRunner 3 Plus, and Specialized Como 4.0 can be compared as examples of that class.

The working method is: Estimate watt-hours per mile from hilliness, double for a round trip, and add a 20 percent reserve. Planning notes are grounded in National Renewable Energy Laboratory. Wind, cargo, and assist level change range substantially.

How to use this calculator

Riders matching a battery pack to a commuting distance. Estimate a watt-hour class from miles and hills. If you can answer one-way miles and hilliness 1–5, this page can produce a class you can shop against.

What this page will not do

  1. Enter the planning inputs

    Estimate battery class by recording one-way miles and hilliness 1–5. Use real measurements or counts, not a rounded marketing number.

  2. Keep optional extras off until they are real

    This tool has no optional add-ons. If a number is uncertain, calculate a range and keep the more conservative class.

  3. Read the battery class

    Estimate watt-hours and treat the headline as a class, not a product name. Matching examples below follow 500–700, 300–400, and 700+.

  4. Compare official pages, then verify

    Open the official page for each example in that class. Confirm current specifications, dimensions, and terms. Decision Lantern does not quote a live price or complete an install review.

Frequently asked questions

How does the e-bike range estimator work?

It converts one-way miles and hilliness 1–5 into a planning class using a published rule. Estimate watt-hours per mile from hilliness, double for a round trip, and add a 20 percent reserve. The headline is a class such as 500–700, 300–400, and 700+, not a vendor ranking.

Is Aventon Level 2 better than Rad Power RadRunner 3 Plus?

This page does not rank Aventon Level 2, Rad Power RadRunner 3 Plus, and Specialized Como 4.0. Aventon Level 2 and Rad Power RadRunner 3 Plus are listed because they are real products with official pages that map to different or overlapping classes. The useful question is which class matches your inputs.

Can I treat the result as a buying recommendation?

Wind, cargo, and assist level change range substantially. Use the class to decide what to read next, then verify fit, terms, and installation requirements on the official page and with a qualified installer when the product needs one.

Do the product links earn Decision Lantern a commission?

Not on the current preview. Links go to official manufacturer or service pages. If compensated links are added later, the disclosure on this page will say so in plain language.

What should I verify after I get a class?

Confirm the current specification, dimensions or plan limits, and any program terms on the official page. This is not a range guarantee or a legal class determination. The next editorial review for this page is due 2026-11-14.

Why these 3 examples?

They are real outdoor options with an affiliate program on file and an official product page. Aventon, Rad Power Bikes, and Specialized appear because each one can represent at least one planning class on this page, not because Decision Lantern tested or endorsed them.
