Tools for this tag

Tag sometimes used to express that (1) riding bicycle is not allowed (2) pushing bicycle is allowed. bicycle=no on object allowing foot traffic is also often used for the same purpose.

In some places it is illegal to both ride and push bicycle[1], there is no good tagging scheme to indicate it[2], bicycle_pushed=no, bicycle_pushing=no and bicycle_possession=no were suggested[3][4].

Objects where both cycling and walking (foot=no + bicycle=no) such as typical motorway are not problematic, as dismounting and walking while pushing bicycle is clearly not OK. But there is no standard way to indicate few places where you are not allowed to cycle, you are not allowed to enter with bicycle and walking (without bicycle) is perfectly fine.

Note that while roads/footways completely banning even pushing bicycles are quite rare compared to ones where just cycling is not allowed, bicycle=no is far more popular. It is used over 942 000 times together with highway=*[5] while bicycle=dismount just 73 000 times[6]. It indicates that majority of mappers is using bicycle=no to indicate places where pushing bicycle is OK.

Even if someone is using bicycle=no with intention to state that pushing/carrying bicycle there is forbidden it is impossible to distinguish bicycle=no mapped with meaning "no cycling" and "no presence of bicycles is allowed". It makes this two tags a de facto equivalent.

As of 2020 "dismount" value is supported by iD while not supported by JOSM. OSRM includes ways tagged with bicycle=dismount in cycling routes but indicates that bike-pushing is required. (Some versions of OSRM similarly recommend pushing a bike against the flow of traffic along a one-way street.)

Tag history

bicycle=dismount appeared and was used without consideration that it de facto duplicates older bicycle=no[7][8][9][10]. This attempt to redefine bicycle=no from "bicycling is forbidden" to "bicycling and pushing bicycle is forbidden" was not succesfull.

Potential redefinition

Multiple people like this tag and want to use bicycle=no for "not even bicycle pushing is allowed".

Standard opposition to deprecation/redefining of major tags is present.

In addition note that as use of bicycle=no for "no cycling is allowed" is very widespread, mappers would need to resurvey all locations where it is used. To track such resurvey some dedicated tag would be needed to mark whether bicycle=no is used for "no cycling allowed" or "no bicycle pushing allowed".

And at that point it is easier to simply have a new tag for rare "no bicycle at all in addition to forbidding cycling" and let bicycle=no mean pushing a bicycle is allowed.
