The urban mobility transition is in full swing. Growing urban populations, increasing traffic congestion and the need for more sustainable transport solutions are forcing cities to think about the future of mobility. This transition is also strongly present within Louwman Group, where the focus has traditionally been on cars, but where mobility is being interpreted more and more broadly. In order to explore what mobility will be relevant in the future, it is crucial to gain more insight into mapping mobility needs and wants in urban areas. This report explores, in the context of three Rotterdam neighbourhoods, how differences and commonalities can form the base for a mobility solution that offers people a more personalised mobility experience in a feasible way. The research revealed that in each neighbourhood, vulnerable groups are excluded from the mobility system in different ways. Through a product-service combination, the issues experienced by these vulnerable groups are explicitly addressed, while at the same time relevance for a wider audience is targeted. This way, the concept reflects the balance between personalisation and generalisation. This resulted in a product/service combination centred on a modular and stable bicycle as an addition to the shared mobility offer in Rotterdam. A stable bicycle (with three or four wheels) caters to older people, people with physical limitations or people who have not (yet) mastered the skills of cycling. These people are often restricted in their freedom and the current system does not adequately meet their needs and wants. The bike offers the opportunity for two people to cycle together, addressing social aspects, accessibility and providing a low-threshold way for people to try cycling. Through a matching process and credit system, people are encouraged to help and support each other in experiencing mobility freedom, safety and integration. In addition, the bike can be used for free or at a reduced rate by eligible people if it is not reserved. Instead of a second seat, modular add-ons can transform the bike for a variety of purposes, such as cargo, child seats and a roof. This makes it relevant and interesting for a wide audience to use.
