Adult tricycle
Stable adult trikes with under-seat or over-seat steering, designed and built in Germany.
An adult tricycle gives you security without giving up the feeling of cycling: you don't have to balance, you can stay seated at every traffic light, and getting on and off is easy. We have been building our 3 wheel bikes in Germany for 30 years, with one steered wheel at the front and two wheels at the back. Choose between under-seat and over-seat steering and find the tricycle for adults that suits you.

Under-seat or over-seat steering?


Under-seat steering: the handlebar grips sit to the left and right of your hips. Your hands, shoulders and neck stay relaxed, and you can lean on the steering unit when you stand up. Models: Kettwiesel ONE, Trigo E.
Over-seat steering: the handlebar sits in front of you, as on a normal bicycle, and all controls are within sight. On the Kettwiesel ONE UP, the steering unit folds up to make getting on easy. Models: Kettwiesel ONE UP, Trigo UP E.
The Trigo's seat height is 58 to 66 cm (23 to 26 in), the Kettwiesel's 52 to 60 cm (20 to 24 in). With the smaller 16-inch front wheel, the Kettwiesel's step-over is even lower.
Sporty adult tricycle
If you like to ride at a brisk pace, three wheels have plenty to offer too. Thanks to its low centre of gravity, the Kettwiesel holds the road firmly in corners, the direct under-seat steering responds quickly, and the full suspension absorbs bumps even at higher speeds. In the Kettwiesel ONE PLUS, the 100 Nm Bosch motor gives you strong drive on hills, and with the optional 800 Wh battery, long tours are no problem. If you want to ride with a sporty edge, this is the right tricycle for you.
Small and light tricycle
A 3 wheel bike should fit through your garden gate, front door and lift. The Trigo is 83 cm (33 in) wide, the Kettwiesel 88 cm (35 in). Both also do well on weight: in its basic specification, the Trigo weighs just 30 kg (66 lb), making it one of the lighter tricycles with a motor. The Kettwiesel starts at 35 kg (77 lb). For transport, the Kettwiesel slides together and, without the front wheel, is then only 135 cm (53 in) long and 66 cm (26 in) high.
Tricycle with 20-inch wheels: why smaller wheels
All our tricycles run on 20-inch wheels at the back. Smaller wheels keep the centre of gravity low and make the tricycle stable. Our tricycles are also very manoeuvrable: when you turn, the rear wheels stay almost in place and the trike pivots around them. The Kettwiesel is available with an optional 16-inch front wheel, which makes the step-over even lower. Puncture-resistant tyres come as standard.
Adult tricycle with or without a motor?
Most people looking for an adult tricycle today choose motor assistance: it makes hills, headwinds and long distances easy. That's why we build all our tricycles with a motor as standard. You decide how much it assists you, and you can also leave it switched off. We explain what matters about the motor, battery and range on our electric tricycle page.

Why our tricycles are built on the delta principle
One steered wheel at the front, two wheels at the back and the seat in the rear third: we have built all our tricycles on this principle in Germany for 30 years. Our tricycles are certified as medical devices throughout Europe.

Stable in every corner
The centre of gravity is low and far back: maximum stability and good grip when pulling away and braking.
Easy to manoeuvre in tight spaces
You can turn almost on the spot, which is handy for manoeuvring and parking.
Sit down instead of climbing on
You sit down between the rear wheels. The under-seat steering helps you stand up again.
At eye level in traffic
You sit high enough to be seen and to keep an eye on the traffic.
Riding together
A tandem coupling links two tricycles, and a trailer set lets you hitch a tricycle to a bicycle.
Funding and subsidies
In many countries, health insurers or public bodies can subsidise an adapted tricycle under certain conditions, for example for therapy or rehabilitation. Our REHA models are designed for this. The rules differ from country to country, so your local dealer is the best person to ask about the options where you live.

Test ride at a dealer or at the Schaltwerk
It's best to buy an adult tricycle after a test ride. Send us your request: we'll get back to you and find the right place, at a dealer near you or at our Schaltwerk in Waltrop, Germany. All current models are ready to try there, and the former colliery site has plenty of room to ride.

Frequently asked questions about adult tricycles
How much does an adult tricycle cost?
Our adult tricycles start at €5,690 for the Trigo E (recommended retail price in Germany, incl. VAT). The price mainly depends on the motor, the steering and the suspension. A full-suspension Kettwiesel with a Bosch motor costs around €10,600. Prices in other countries may differ, and your local dealer can tell you more. In the configurator you can see the price of your specification straight away.
What is the best adult tricycle?
The best adult tricycle is the one that suits you. There is no overall test winner, because tricycles are built for very different needs. When you read reviews, look at stability, brakes, how easy it is to get on and the load capacity. A test ride is the most reliable way to find out.
How big is a tricycle's turning circle?
That depends a lot on the design. On our tricycles, with one steered wheel at the front and two at the back, the rear wheels stay almost in place when you turn and the trike pivots around them. This keeps the turning circle very small, so you can easily handle narrow driveways, garages and paths.
Is an adult tricycle hard to ride?
No. You don't have to keep your balance on a tricycle. Unlike on a bicycle, though, you don't lean into corners. So take corners a little more slowly on your first rides; after a few minutes it will feel normal.
Can an adult tricycle tip over?
A tricycle built on the delta principle is very stable: the seat sits in the rear third and the centre of gravity is low between the rear wheels. Even so, you shouldn't take tight corners at full speed.
What is the maximum rider weight for a Hase tricycle?
The Kettwiesel and Trigo are designed for a load capacity of up to 140 kg (309 lb). A higher load capacity is available for the Kettwiesel ONE as a custom build.
Where can I test ride an adult tricycle?
The easiest way is our test ride form: we'll get back to you and arrange a test ride at a dealer near you or at our Schaltwerk in Waltrop, Germany. If you'd rather get in touch directly, our dealer search will help you find a contact near you.
