Xmas Opening Hours: Our last day is the 23rd of December, then closed until the 5th of January. Happy Christmas!


The Kettwiesel’s delta design is simple, but incredibly effective. You are low down and almost between the back wheels, so the Kettwiesel is very stable, and the single front wheel makes it very manouverable as well.

This geometry also means that the steering system is much less complex than the tadpole geometry (see the Scorpion) – so it’s light and reliable. Because you can turn the front wheel about 75 degrees, the Kettwiesel can turn in its own length.

The Kettwiesel is also light (16kg), so you can take it almost anywhere.

Riding a Kettwiesel is an experience you have to try – about the closest thing I can describe it to is a go-kart, but it’s probably even better than that. If you really push it, you can lift the inside wheel, and with a bit of practice two-wheel riding is easy.

The componentry is simple and reliable. Independent disc brakes on each back wheel are operated by two levers, and one gear shifter shifts through the 9 wide-range gears.

The Kettwiesel isn’t just a toy, though. An optional coupling lets you attach a BOB trailer for touring, and another optional coupling lets you connect two Kettwiesels together to make a tandem. Apparently more than five in a string is not a good idea…

The Kettwiesel is also very adjustable! A couple of clever chain pulleys let you adjust the length  to suit you without having to add or remove links. For bigger adjustments, the pulley can be moved to one of several sets of mounting holes.

There are three different versions of Kettwiesel:

The Allround has an aluminium frame and comes with either 8-speed linear derailleur gearing, or a sealed Nexus hub gear, both versions have mudguards and hub dynamo lighting.

The Evo has a folding full suspension frame – undo one clamp and pull a cable, and it folds up to fit easily into a car boot, and the seat folds flat too. The Evo has a Nexus settled hub gear, and the Evo can also have the Shimano STEPS electric assist system.

The Cross is like the Evo, with a folding frame and full suspension, but it is built for off-road use with an 11-speed linear derailleur driving both back wheels through a differential. Like the Evo, it can also have the Shimano STEPS electric assist system.


The Kettwiesel can also be turned into a really good handbike – see here for info…

  1. My husband, who can no longer walk or ride his normal bike, loves his trike. We had a lovely ride this morning at St Trojan on the Illegal D’Oleron, France
