Meet Siggi

everyday life

Everyday performance

Siggi offers the best of both worlds: An amazing riding experience and a compact fold. When designing Siggi, we wanted to create the ideal bike for the urban environment and beyond. It is packed with features that enhance the performance of the ride, while still maintaining a compact fold so you can bring Siggi everywhere. Siggi offers the perfect mix of EVERYDAY PERFORMANCE and EVERYDAY CONVENIENCE.

The fold

Bring Siggi anywhere

Siggi doesn’t just provide a stable and responsive ride. Thanks to the cleverly designed folding mechanism, Siggi is also super compact when you need to take the train, bus or store it in the trunk of your car.

20" wheels

Accelerate your commute

The size of Siggi’s wheels is a key determinant of the solid riding experience. Being smaller than a standard-sized bike, they are quicker to accelerate, but being larger than on most folding bikes, they also offer a more stable ride.


Smaller wheels offer greater acceleration. A more responsive ride is perfect for when you ride through the city, where you have to stop at red lights or slow down when turning and quickly accelerate again.


When designing Siggi, it was crucial to us that we didn’t compromise on Siggi’s riding experience. Opting for 20″ wheels, we felt that we found the optimal balance between responsiveness and stability.

StoneWeave frame

Rock solid,
light & durable

Siggi features our proprietary frame material, StoneWeave, which is an innovative mix of carbon and basalt. It is lightweight, stiff and super durable.


Experience the feel of a road bike on a compact folding bike thanks to Siggi’s geometry of speed. The StoneWeave frame is stiff and lightweight, making it both high performance and easy to carry when you arrive.


Siggi’s StoneWeave frame is not just super durable thanks to the basalt laminate that absorbs shocks from the road and enhances the carbon. StoneWeave is also recyclable at the end of it’s lifespan, meaning we can extract the carbon fibers and reuse them. Siggi is the first Coh&Co model to feature recycled carbon fiber parts.

Full suspension

any terrain comfortably

Siggi is not only ideal for the brief commute in the city, it is also a super comfortable ride when travelling longer distances. To compensate for the reduced comfort of the small wheels, Siggi has elastometric suspension blocks integrated front and back, ensuring you can enjoy your ride comfortably no matter how far you are going.

In partnership with Zehus Motors

It all works in unison!

The integrated motor, battery and electronics work seamlessly to assist you while pedaling, and then to recover energy when back pedaling.

Kinetec Energy Recovery System

The HALOS features the clever Kinetic Energy Recovery System (KERS), which allows the motor to collect braking energy to recharge the battery

The KERS improves the range by up to 20% and save more than 50% of the brake pads life

A sustainable eco system

Coh&Co is on a mission to raise the bar on how we experience riding, maintaining, and owning our bicycles. We have developed an ecosystem to keep bikes rolling and by your side for many years to come.

It starts at the design process where we push the limits of longevity with our sustainable material technology StoneWeave – and we close the circle with a transferable lifetime buy-back guarantee. We refurbish or recycle every registered bicycle returned to us when it has reached the final crossroads in its lifecycle.
