eCYCLE: Impact of Long-Term E-Bike Rental Programs on Daily Mobility and Health

Long-term rental programs for electric-assist bicycles (e-bikes) have expanded across France, offering access to a bike for several months at a competitive cost. Despite their widespread deployment, these programs have never been subject to rigorous scientific evaluation.

The eCYCLE study aims to fill this gap. Its primary objective is to produce the first evidence-based data on the impact of these programs on daily mobility — and in particular on modal shift from car to bike. In parallel, we seek to quantify the effects of regular e-bike use on users’ health, with a focus on mental health.

A first version of the study is currently underway in Rennes, with plans to roll it out nationwide in the coming months.

Associated Projects

eCYCLE is part of a broader set of complementary projects:

Passive mobility tracking. We are currently validating an application that automatically detects everyday travel patterns using the GPS built into smartphones — with no input required from the user. This approach represents a significant step forward compared to conventional questionnaire-based methods, which tend to be imprecise and burdensome.

Supporting adoption in challenging weather conditions. Autumn months see the highest number of new e-bike rentals: this is when transitions toward e-cycling are most common. Paradoxically, it is also a period that is particularly unfavorable for building new travel habits — rain, wind, and reduced daylight are well-documented barriers to cycling. As part of the Rennes study, we are developing a motivational support intervention delivered through an app, in the form of personalized messages and tailored advice. Our hypothesis is that such support can complement access to the e-bike itself and promote lasting e-bike adoption among new users.
