Calculators

Four small calculators help with the numbers. All values are rules of thumb and assumptions, not promises.

  • Range calculator

    How far does the battery take you? As a range, with a cold-weather deduction.

  • Cost calculator

    What does the conversion cost in total, and does it beat a used or new e-bike?

  • ETRTO and wheel sizes

    Enter the tyre marking and learn the ETRTO size and the traps.

  • Bottom bracket calculator

    Measure the shell width and see which mid-drive kits fit.
