Foldable cargo bike for flexible use in everyday life

Cargo bikes are seen as a practical alternative to cars - but at the same time they have clear limitations in everyday life. Size and weight in particular often make transport, parking and use inflexible.

One concept attempts to address precisely these weaknesses by making the cargo bike itself customisable. The focus is on a foldable cargo bike that is not only suitable for transporting goods, but can also be folded up compactly. This shifts the focus from pure transport performance to suitability for everyday use.

Avnson develops foldable cargo bike with a system

Avnson's approach is aimed at increasing flexibility in the use of cargo bikes. Instead of using a permanently large vehicle, the bike can be folded up when required and stowed away to save space. The system starts with the steering column, which can be folded in. The central frame mechanism is then released via a safety lever and a main lever. The saddle is also released so that the entire bike can be folded into a compact shape. This sequence shows that folding is not an additional function, but an integral part of the design.

Folding mechanism enables transport and storage

When folded, the cargo bike can be rolled - comparable to a large piece of luggage. Carrying is only intended to a limited extent; the focus is clearly on rolling and parking. A further step is to turn the bike 180 degrees. This means that both wheels are in contact with the ground, which enables transport on a rear carrier. This solution extends its use beyond purely urban transport. This is a particular advantage when travelling or transporting in a car. The cargo bike can be taken along without taking up too much space.

Adapter system for frame and drive

A central element of the design is a modular adapter system. The frames remain identical during production, while different components can be integrated using adapters. This applies in particular to the drive unit. An existing bike can be retrofitted without having to replace the entire frame. At the same time, new motor systems can be integrated as soon as technical developments arise. The luggage carrier also follows this principle. Batteries are attached using a similar system and can be customised accordingly. The most important features of the system at a glance:

• foldable frame with multiple release points
• rollable state for easy transport
• Rotation function for use on rear carriers
• modular adapter system for components
• Drive and battery can be retrofitted

Sustainability through retrofitting instead of replacement

The idea behind the adapter system is closely linked to the issue of sustainability. Instead of completely replacing a cargo bike in the event of technical changes, individual components can be replaced. This applies above all to the drive. As motor systems evolve quickly, the concept enables customisation without the need for a complete replacement. Existing bikes can also be retrofitted. This approach reduces material requirements and costs in the long term. At the same time, the bike remains usable over a longer period of time.

Everyday use between transport and mobility

The practical application can be seen in everyday life. Cargo bikes are often used for transporting children or shopping. However, the requirements are also changing with increasing popularity. Many users only use a cargo bike in certain phases of their lives. When it is no longer needed, it is often sold or replaced. The concept presented here attempts to make this utilisation more flexible. The ability to fold the bike makes it easier to store it in the basement or indoors. This protects it from the weather and reduces maintenance costs. At the same time, the risk of theft is reduced as the bike does not have to be permanently parked outside.

Classification of the concept in the market

The foldable cargo bike shifts the perspective on this vehicle class. Instead of focussing on maximum transport capacity, the focus is on adaptability. Avnson is thus pursuing an approach that brings cargo bikes closer to everyday life. The combination of folding mechanism, modular design and retrofittability aims to lower the barriers to entry. With a price level of around €6,299 for the basic model and around €6,499 for the e-bike version with Shimano EP6, the concept is in the upper segment. The decisive factor here is not so much the price as the question of whether the additional flexibility increases the practical benefits. The result is a cargo bike that can not only transport goods, but also adapts to different situations - and this is precisely where it differs from classic solutions.
