EUC Calculator

Range is the question every EUC buyer and rider asks, and the honest answer depends on a dozen variables — rider weight, speed, tyre pressure, temperature, riding style, battery degradation. The brief was a calculator that takes all of them and still feels like a single screen, not a spreadsheet.

• Wheel selection from a preset list (with a custom option for any other wheel) that pre-fills battery capacity
• Riding parameters as toggles: riding style, tyre type, road surface, sitting or standing
• Sliders for rider weight, average speed, tyre pressure and air temperature, each with unit switches (kg/lbs, km/h/mph, bar/psi, °C/°F)
• Result shown two ways — expected range on a full battery and continuous ride time — with a relative range-quality indicator
• Every factor explained in plain language under the result, including how battery degradation is treated
• All calculation on the client, so results update instantly and the tool works inside the EUC.ONE progressive web app

A calculator riders trust because it shows its work: move one slider and the range and ride time update instantly, with the assumptions written out rather than hidden — and it lives inside the EUC.ONE app, where the decision gets made.
