Small changes in assist and average speed are the levers you have on every ride—try a lower level before you add more battery.
Panniers to balance cargo, insulated battery bags for winter, and spare packs when you can’t top up at work.
Phase 2 will let you name your bike, track wear by distance, and nudge you before parts fail. Join the waitlist to hear when it ships — calculators stay free.
Join the waitlistMost brand calculators only work for that brand’s own motor, and they rarely factor in cold mornings, a loaded rack, or how hard you use assist. This tool is built for the ride you actually do: you enter the battery’s watt-hours from the label, your weight plus any cargo, terrain, average speed, and how warm the battery is during the ride. We apply realistic drag from temperature and age, then show a range band—not a single optimistic figure—plus how much of a round trip you would use. Use it to interpret brochure numbers, plan school runs, or see whether a spare charge makes sense. The maths runs on the server, updates as you type, and nothing is stored.
