Like Westminster the centre of Lille is chock full of one-way streets but, unlike Westminster, there's clearly a major push to introduce contra-flows for cyclists, facilitating their movement, as the sign above shows. In addition much of Lille's centre has motor-vehicle bans. The result is many people walking and cycling (with no hi-vis or helmets to be seen).
While there doesn't appear to be a B-Bike scheme, you can hire Segways and Electric Bikes at the rail station.
