Painted bike lanes are safer for cyclists than riding in the middle of the road, but bike lanes that are separated with a curb are even better. For example, one study found that cyclists in separated lanes had 80% fewer accidents than those in regular bike lanes. But it’s often tricky to convince city governments to take the extra, more concrete step of separation. One product from a U.K. design firm aims to help.
The “Armadillo” is a low-slung recycled plastic bump that can be installed along the edge of a bike lane. Set at an angle, the bumps allow enough space for bikes to ride back out into the street if they need to, something that isn’t as easy with a full concrete curb. But it still keeps cars out.
