About the Duetta

The Duetta is a versatile and adjustable bicycle that can accommodate different riders and riding styles. Children can ride but it can also be ridden by 2 comfortable adults. You can see the Duetta in action by checking out our videos in the gallery and on our social media channels.

Both people can pedal and handle the Duetta! The pedals are double, and the angle of the handlebar can be adjusted so that the bike can be ridden also from the back. You can see videos in the gallery and on our social media to see it in action!

The Duetta is not built for competitive cycling. It’s the perfect bike for a leisurely ride with a friend or loved one, allowing for comfortable conversation and a shared experience.

The rear handlebar on the Duetta allows for the person sitting in the back seat to have a secure grip and contribute to pedaling. Additionally, the front handlebar can also be adjusted for both riders. Check out videos in our gallery and on our social media to see the Duetta in action!

We always recommend that when building the Duetta, it’s important to select the right components and use proper manufacturing techniques to ensure it can support the weight of two people. See the Duetta documentation.
