HASE BIKES KETTWIESEL

The swiss army knife of recumbent trikes

The standard setter of high-end trikes
​The Kettwiesel is the most adaptable performance trike in the Hase Bikes lineup in terms of sizing and functionality.

Adjustable and foldable
The Kettwiesel offers an extremely adjustable frame (suits riders from 4'6'' to 6'7'')  and foldable options. It also has the conventional advantages of delta trikes in stability, comfort and easy handling, 

For grocery shopping and cross-country traveling
The Kettwiesel can come with full suspension and a variety of tires. The wheels on its Quickstick hubs can be changed and removed for transportation easily by loosening a bolt. The Kettwiesel can carry cargo up to 100L, making it perfect for an easy ride to the local stores or for long-distance rides. 

Unparalleled Customization
The Kettwiesel is fully customizable. Start with one of the base models, and build your Kettwiesel. Almost 40 adaptive inclusive options including armrests, special pedals, shoulder pads and more are available for a variety of abilities and impairments. 

Electric assist
A Shimano Steps motor can easily be mounted - and also removed - in a few easy steps. The electric assist system with a capacity up to 60 miles can help both beginner and advanced riders to achieve more power and endurance.
