Key differences

Supported differences are shown below. Data limitations are labeled separately.

  1. Frame geometry

    2025 Kona Ecoco has 10 mm more stack than 2021 Kona Ecoco in the selected sizes.

    More stack places the frame reference higher, not necessarily the handlebar.

  2. Gearing

    2025 Kona Ecoco has a 6% lower climbing ratio than 2021 Kona Ecoco.

    A lower ratio gives more mechanical advantage; rear-wheel rollout determines distance per crank turn.

  3. Identity & price

    2025 Kona Ecoco had an original MSRP $600 lower than 2021 Kona Ecoco.

    Original MSRP is the published list price when new, not today’s used-bike value.

Selected-size geometry

Geometry overlay

Frames share one scale and a bottom-bracket alignment. Size labels differ by brand; schematic drawing aids are identified below.

Gearing comparison

Lower gears help on climbs. Higher gears suit higher speeds.

RPM

RPM = pedal turns per minute.

Lowest1.12:1Highest3.45:1Total range309%

Speed unavailable: wheel or tire size is missing or unclear.

Estimated speed at 90 RPMLowest gear7.4 mphHighest gear24.2 mph

Rear tire: 650C×47.

How it works

Ratio = front teeth ÷ rear teeth. Hub gears also include the hub’s internal ratio. A 400% range means the highest ratio is four times the lowest.

Speeds are estimates from tire size and pedal cadence. Actual speeds vary.
