Our development principles

Symbiosis of design, innovation and technology inspired by vehicle development.

Our mission: to better protect drivers, passengers and passers-by and thus bring them safely to their destination.

The use of innovative materials and tried-and-tested construction methods from child seat and automobile development has opened up new possibilities, which have significantly improved the passive safety concept of the Ca Go.

Passenger protection

The special design features of the cargo bikes, such as a central driver's seat and missing A/B/C columns of the "passenger cell", represent a major challenge for the occupant protection concept.

The aim was to design effective safety components for the single-track Ca Go electric cargo bike (also known as LongJohn) for the small passengers.

For this purpose, the Ca Go designers and constructors developed the CargoBox in cooperation with Schumpeter as a stable safety cell made of EPP, which partially absorbs the energy resulting from a fall, overturning or collision. The involvement of orthopaedists, medical doctors and ergonomists led to the development of the passive restraint system, consisting of 5-point safety belts, height-adjustable headrests, adaptive swinging seats with slip-through protection (submarining effect). In addition, kinetic energy absorbing materials are used in the backrests of the child seats. The high shoulder line of the CargoBox prevents the child from reaching out during the journey and also reduces the risk of falling out and resulting head injuries.

The result ensures the minimum protection for small passengers in the event of an accident.

Passer-by protection

Due to the size and weight of the cargo bikes or family bikes, average speeds occur in conjunction with the e-drive, at which pedestrians are also exposed to the risk of injury in the event of a collision.

These risks of injury to the musculoskeletal system are reduced by the EPP cladding and rounding off of many potential contact points of the Ca Go with pedestrians.

Homogeneous design

Integrative design


Shock protection

Expert knowledge

Child safety is the top priority at Ca Go. That is why we work together with experts from different fields to achieve a common goal:
The perfect symbiosis of functional design, high safety and high quality.
Patent pending developments and a contribution to safe, urban micromobility are the result.

With the growing popularity of alternative mobility, the number of cargo and family bikes in cities is also increasing.

The high car and traffic density, combined with the marked potential for improvement of the bicycle infrastructure in many cities, automatically leads to increased danger situations and thus minimum safety requirements for passengers, drivers and pedestrians.

This gave Ca Go designers and developers the drive to analyse and understand the specific safety requirements for cargo and family bikes in order to further develop and continuously improve the safety concept of these city vehicles.

What makes our Family & Cargo Bike safe.

The CargoBox by Schumpeter

Safety Rail

The bracket, which is firmly screwed to the frame, acts as an integrated side impact protection covered by EPP. It holds and protects the CargoBox and transmits the forces acting on it. For safety and additional stability.

Bracing structures

The use of vertical and horizontal bracing elements enables the transfer of forces to and from the CargoBox, as in the static and structural design of buildings. Similar to truss construction and honeycombs. For increased stiffness and load capacity.

High shoulder line

For increased child safety and pleasant visibility. Restricts the field of vision of the smallest passengers in a calming manner and also prevents them from reaching out during the ride. Protects the head and reduces the risk of falling out in the event of a fall.

Energy absorbing material

strength at low weight, high stiffness, high energy absorption capacity, water-repellent - the list of outstanding product properties of expanded polypropylene (EPP) is long. Here more about the material multi-talent of the CargoBox by Schumpeter.

Storage compartments and nets

For everything that has to go with me, or is collected on the way. For more order in the box.


To help children get in and out easily.

The child seats

The comfortable and practical seating solution for children from approx. 2 to ca. 9 years.

The ergonomic Ca Go child seat grows with your child and offers safe comfort in sitting or resting positions, soft padding and an easily and correctly adjustable headrest.

The seats are positioned low enough in the CargoBox to protect the shoulder line - at just under 12.5 cm from the box floor but high enough to allow a comfortable leg position even for older children.

The firm basic structure of the seats increases the support properties and thus enables sitting in a manner that is appropriate for the spinal column. Developed with ergonomists and orthopaedists.

5-point belt

The adjustable 5-point harness with quick release buckle. For easy buckling and secure hold. Firmly anchored to the frame.

Adjustable headrests

The adjustable headrests can be easily and correctly adjusted.
The mesh cover allows a comfortable head position even with a helmet.

High backrest & seats

The length of the backrest is designed for the height of children between 2 and 7 years of age.


For the little ones who do not yet fit on the Ca Go child seats, an Isofix mount is optionally available to securely fix child seats or an Isofix base e.g. for Maxi Cosi, Pebble etc. in the box without problems.

folding seat surface

In case there are no passengers, the seat can simply be folded up to get more storage space in the box.

Problem-free conversion

The Ca Go can be easily adapted to your requirements.
The child seats can be selected individually during configuration or can be ordered later. The simple, quick and safe installation makes the change from one to two child seats a child's play.

9% inclination for safe and comfortable sitting.

The seats offer a backrest and foam parts shaped to fit the spine and a sufficiently high backrest (backrest height = shoulder height).

The angle of the vibration-damped seat, which is also inclined by 9 degrees, ensures that the thighs rest correctly.


Adaptable to different body sizes

The child seats can be adapted to different body heights due to the adjustable headrests (upper edge of the headrest = upper edge of the head) and the adjustability of the seat height for younger children, due to the optional seat elevation.

The Isofix mount (optional) and optional Maxi-cosi adapters also allow infants to be transported in appropriate infant carriers.

Perfect for children from 2 to 7 years*

Designed with ergonomists and orthopaedic surgeons especially for use in load bikes. The comfortable and safer transport solution for children up to 120 cm tall.

A sophisticated damping concept for comfortable and agile driving pleasure.

Damping is not suspension - and yet in practice the two are almost inseparable.

Balanced damping concepts and component tuning are aimed at optimally taking into account the driving style and situations, the terrain, the load condition and the occupants or drivers.

For the Ca Go, a combination of a front suspension fork specially developed for cargo bikes and balloon tires (pneumatic suspension) was developed in cooperation with specialists from Schwalbe, Idworx and Suntour. In this way, the voluminous air cushion of the significantly wider special tires with a relatively low air pressure acts as a natural damping with very good rolling behavior - thus making complex rear suspension technology unnecessary.

The innovative e-cargo bike in terms of safety, quality and technology.

The Ca Go bike has been thought out in detail and equipped for high everyday use with riding fun: For relaxed and safe rides.


Design: Sporty, agile and robust

The Ca Go bike sets new standards in construction and design. Robust proportions, powerful presence, dynamic lines. But the actual special features of our design are measures which optimize the riding performance, load distribution and passenger safety in every detail. For example, the Ca Go has a low centre of gravity, which improves the handling of the E-CargoBike. In combination with the cable steering, tires with a rubber compound specially adapted to the front and rear wheels, and a Magura brake system designed for cargo bike operation, nothing stands in the way of safe riding fun.

Strong drive - best electric motor on the market

In the heart of the Ca Go the new Bosch Cargo Line engine works with 85Nm which is supplied by up to 1.250Wh battery capacity. This is made possible by the integration of two Bosch Powertubes 625 Wh batteries, which are hidden under the loading area in the floor of the box to optimize the center of gravity.

Low-maintenance belt drive

Gates' silent and lightweight belt drive optimally transmits the power of the Bosch engine in combination with the Enviolo AutomatiQ. The automatic tensioner pulley is an innovation by Ca Go and eliminates the need for frequent testing and re-tensioning of the belt, which is made of carbon strands and has a long service life or mileage.


Driving comfort at the highest level

The high torsional stiffness of the lightweight aluminium frame ensures optimum driving performance. The low chassis and the low centre of gravity optimised for a LongJohn (load distribution 30% front wheel / 70% rear wheel) in combination with the damping concept, which has been specially designed for a Family CargoBike, consisting of a front fork, shock-absorbing child seat and extra-wide 70mm balloon tyres at the rear, ensure high riding and seating comfort. For comfortable, safe rides and relaxed naps for the little passengers.

“We want your family bike to set new standards in handling and child transport, and at the same time be easy to use. That's why we have listened carefully to parents, children, cargo cyclists and many other experts during the development process to understand your needs for usability and safety. Many ideas that will help you every day have been successfully implemented. Have fun !“
