Blue-bike was founded in 2011 by the NMBS (Belgian Railway Operator). The blue sharing bikes offer train and bus users more freedom to cover the last kilometers from the station to their final destination. 

Today you can borrow a bicycle at more than 70 locations throughout Belgium. Since the start in 2011 more than xx rides have been made by more than 200.000 members.

With the smart locks and technology of Sentinel we are ready for the future. Not only can now quickly scale up to hundreds of additional locations but we offer our customers to easily use bike by presenting the public transport RFID card directly to the lock. Because almost no infrastructure is needed we can easily open new locations or adjust the capacity on existing locations.

Mobit was launched in September 2017 and we were the first free floating bike sharing scheme in Belgium. To date over half a million rides have been made with a Mobit bike in Belgium.

Sentinel is our technology partner for the locks, the software and the smartphone app. The Sentinel public bike sharing platform is very reliable, easy to use and offers an abundance of features (geofencing, deposit & wallet function, messaging, ...). The platform was tuned to our specific needs, including look and feel.

The automated functions allow us to run Mobit at a very low operational cost.
