Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Frame geometry
2019 Kona Hula has 7 mm more reach than 2020 Kona Hula in the selected sizes.
More reach puts the head-tube reference farther forward, not necessarily the hands.
- Frame geometry
2020 Kona Hula has 25 mm more stack than 2019 Kona Hula in the selected sizes.
More stack places the frame reference higher, not necessarily the handlebar.
- Gearing
2020 Kona Hula has a 13% lower climbing ratio than 2019 Kona Hula.
A lower ratio gives more mechanical advantage; rear-wheel rollout determines distance per crank turn.
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.

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.
