ACCESSORIES
Our new Kettwiesel ONE is super simple to use...

​... and put back into standby mode:
Just pull and go!

Simply loosen the screws on the frame with the tools supplied (and those found on the handlebars for the under-seat steering version) and pull the trike to the desired length. The same applies when transporting it: Loosen the screw(s), push together, fold down the handlebars and handlebar unit - and pop it in your trunk.
Easily adjust the seat position

You have two seating positions to choose from, each one has infinitely variable backrest settings: You can either sit upright or in a more dynamic seated position - anything is possible.
Handlebars up - out you get!

You won't find a smoother ride: The above-seat steering allows you to adjust the tilt and length to size of the rider and fold up when parking or dismounting.
