Which Tools Fit Your Ride?
Pick the situation that sounds like you and get a short path through the tools, in the order that makes sense.
Three numbers to settle in the first week: what to insure it for, what the home policy would really pay, and whether the frame fits.
- Bike Insurance Value Calculator Add the bike, upgrades, and accessories into the stated value before the first ride.
- Homeowners Claim vs. Bike Insurance Calculator See what the same bike pays on a home policy after depreciation and a $1,000 deductible.
- Bike Size Calculator Confirm the frame size and set the saddle height.
Class decides where you can ride and whether a bike policy applies; range decides how far; value decides what a theft pays.
- E-bike Class Finder Class 1, 2, 3, or outside the system, from throttle, speed, and motor power.
- E-bike Range Calculator Miles per charge for your battery, assist level, weight, and terrain.
- Bike Insurance Value Calculator Motor and battery count toward the stated value; make sure they are in it.

- E-bike Range Calculator On an e-bike, check that the round trip fits one charge in winter.

Two calculators answer the two questions every quote comes down to: what is the bike worth, and what would the alternative pay.
- Bike Insurance Value Calculator The stated value to put on the quote, with the total loss payout at your deductible.
- Homeowners Claim vs. Bike Insurance Calculator Home policy payout after depreciation, deductible, and surcharge, side by side.

Frequently Asked Questions
- Are the cycling calculators free to use?
- Yes. Every calculator on this page is free, runs in your browser, and asks for no email or account. Nothing you type is sent anywhere: the math happens on the page, and the results disappear when you close it. Use them as often as you like.
- Where do the formulas come from?
- Each calculator has a "How It Works" section under the tool that shows the formula, the default values, and the source behind them: the 2024 Compendium of Physical Activities for calories, the IRS standard mileage rate for commute savings, the Tanaka equation for maximum heart rate, and the policy terms for the insurance tools. Change any default that does not match your situation.
- How accurate are the results?
- The results are good planning estimates built from published formulas and your own inputs. Training zones and calories carry the normal error of any age or weight based formula, and e-bike range depends on wind, hills, and how hard you pedal. The insurance calculators use the policy's own terms, so the stated value and total loss math is exact for the numbers you enter.
- Which calculator should I use before buying bike insurance?
- Start with the bike insurance value calculator: it adds the bike, upgrades, and accessories into the stated value to put on the quote. Then run the homeowners claim comparison to see what a theft would pay on a home policy after depreciation and the deductible. Both take under a minute, and the value calculator carries your number straight into the quote form.
