Range estimator

How far will it go?

Range depends on what you carry, where you ride and how cold it is. Tell us about your rides and we’ll show you an honest number, with the working.

Start from a typical ride

Battery
220 lb

You, plus kids, bags and groceries. The Portage carries up to 400 lb in all.

Terrain
50°F

Cold cells give less energy, even with the battery heater on.

Assist level

Estimated range

33miles

Most rides like this land between 29 and 37 miles on the standard battery.

Dual · 900 Wh47 mi

Your round trip with 25% to spare: 15 mi

How we worked it out

  • 625 Wh battery, about 90% usable: 563 Wh
  • 50°F: the cells give 94% of their energy (the heater helps, but cold still costs range)
  • Tour assist: 13 Wh a mile on flat ground with 200 lb aboard
  • Rolling: +18% energy a mile
  • 220 lb rider and cargo: +4% energy a mile
  • Together: 16.0 Wh a mile, so about 33 miles

The standard battery covers it

Your 12-mile round trip uses about 36% of a charge on the standard battery, with plenty to spare.

Build with the standard battery

Estimates come from our own test rides with riders from 120 to 300 lb. Wind, tire pressure and how often you stop all change real-world range.
