The Kwiggle's 6-speed gearing

The Kwiggle's 6-speed gearbox still has two lighter gears and one heavier gear compared to the 3-speed, made for the mountains.

You can ride up to 14% slope with it. So you can get up almost every alpine pass with it.

Limits also exist here when it gets particularly steep.

Furthermore, you can still pedal comfortably with the heavier gear even at higher speeds from 25 km/h.

See the video. With the right heel you shift into the heavy 3 gears and with the left into the light 3 gears.
