Five calculators that do real arithmetic

Everything here runs in your browser. Nothing is sent anywhere, nothing needs an account, and every formula is explained on the page that uses it, including where it stops being reliable.

Range calculator

What a battery actually delivers once rider weight, hills, speed and cold are in the arithmetic. Enter a claimed range and it will tell you what fraction of it is realistic.

Use it: Before you buy, and before any ride longer than you have done on that scooter.

Charge time and cost

Hours to your target charge from where the pack is now, modelling the constant-current and taper phases separately, plus what the electricity costs at your rate.

Use it: When you need to know whether a lunch break is enough, and what a year of charging really costs.

Commute cost comparison

Five year totals for scooter, car, rideshare and a transit pass, with the break-even month. Handles both the keep-the-car and replace-the-car cases, because they differ enormously.

Use it: When you are trying to justify the purchase, or work out that you cannot.

Rent or buy

Per-minute share pricing, daily rental rates and ownership on one axis, with the crossover expressed in weeks of your actual usage.

Use it: After your third week of unlock fees.

State law checker

Puts your machine in the right legal class from its power and top speed, then hands you the exact questions to ask and a link to the agency in your state that answers them.

Use it: Before the first ride on any new scooter, and before riding one in a state you do not live in.
