Cycle lanes and greenways are multiplying, and so are the near-misses where a painted bike lane meets a real road. Paint tells a driver the lane is someone else's; a post tells the car it cannot enter it. For a rider at speed, that physical edge is the difference between a pleasant ribbon and a sudden swerve into traffic. The right bollard gives cyclists room without turning the corridor into a wall.

Why paint is not enough

A marked lane lives or dies by driver mood. Delivery vans stop in it, cars drift across it, and the rider is pushed out into the flow. A continuous run of fixed posts sets a hard edge between the cycle way and the carriageway, so the bike ribbon stays a bike ribbon whatever the driver behind is thinking.

Spacing that blocks cars, not bikes

The trick is the gap. Posts set close enough that a car cannot thread through, yet wide enough for a bike, a wheelchair or a pram, keep the lane for its users without trapping anyone. The fixed bollards page covers the heights and spacings that read as open yet still stop a vehicle.

Automatic posts at the crossings

Where the greenway meets a service road or a municipal street, an automatic post drops for the maintenance truck, the ambulance or the bus, then rises again. One cabinet drives the row, so the path stays continuous for riders but never strands the vehicle that genuinely belongs there. See the automatic bollards range for the control options.

Visible and weatherproof

A roadside post lives outdoors and unseen at night is useless. UPARK units take reflective banding and a sealed IP67 casing that shrugs off rain and a gritter's spray, so the edge stays visible through a wet winter commute. The electromechanical screw drive has no oil to leak onto a shared path, which matters on a route used by children.

Retrofit without tearing the park up

Most greenways thread through heritage banks and planted verges where a drainage pit is a disaster. A 36V, sealed, trenchless unit drops in without wrecking the landscaping, which is why these posts suit parks and old corridors where a pumped system would never get approved. For the rare full closure, a few removable bollards lift out for a event day.

The bottom line

A cycle network is only as safe as its weakest edge. A bollard line turns a painted suggestion into a real one, quietly, for every rider, every day. For a town building for bikes, that edge is the single best spend on the path.
