DUOTTS C29 range calculator

The factory 100 km assumes ideal conditions. This calculator uses a simple energy model; real range also depends on terrain, wind and battery condition.

§02Assumptions

How we calculate

The whole model is a handful of multipliers. If your numbers differ, this shows what to adjust.

Wh/km = base[eco 7 | normal 10 | high 14]
      × (1 + (kg − 75) × 0.004)
      × cold[≥10 °C 1.00 | <10 °C 1.15 | <0 °C 1.30]
      × city[1.10]
km    = Wh[720 | 1800] ÷ Wh/km
  • Base consumption by assist level: Eco 7, Normal 10, High 14 Wh/km.
  • Weight factor: 1 + (kg − 75) × 0.004, using rider and cargo combined.
  • Cold: +15% below 10 °C, +30% below freezing.
  • Stop-and-go city riding: +10%.
  • Battery: 720 Wh (C29), 1800 Wh (C29 K: 720 + 1080 Wh).
  • Not modelled: hills, wind, tire pressure, battery age, and the fact that some of the rated capacity isn’t usable in practice.

§04Terrain

Pest is flat, Buda isn’t

The model assumes flat ground. That’s roughly true in Pest, but in Buda every climb towards Gellért Hill, Rózsadomb or Svábhegy raises consumption. If you ride in Buda a lot, plan with the higher assist level or keep a reserve.

§05Tips

More kilometres from the same battery

  1. Keep tire pressure within the range printed on the sidewall.
  2. Use a lower assist level on the flat and step up for climbs.
  3. Start and accelerate smoothly; hard starts use the most energy.
  4. In winter, store and charge the battery indoors at room temperature.
  5. Shift to an easier gear before you stop, so restarting takes less energy.
