Hi,
Dead-end trap or no access or lilmited access for bicycle should be tagged as "bicycle=no" (traffic_sign) or "bicycle=use_sidepath" (use compulsory cycleway).
But this tagging is not correct according to a very few Dutch mappers. This segment does not have a traffic_sign, nor is there a compulsory cycleway (parallel).

Therefore it was suggested by me to use:
exit:bicycle=no (if dead-end trap is by highway segment having "bicycle=no")
exit:bicycle=use_sidepath (if dead-end trap is by highway segment having "bicycle=use_sidepath")

So exit:bicycle=<reason> for dead-end.
Two "reasons" may apply. A simple "noexit= yes" cannot make the distinction between "no" and "use_sidepath".

"bicycle=no" applies to all types of bicycle in all circumstances.

"bicycle=use_sidepath" applies to most type of bicycle, but not for all: a bicycle having a width > 75 cm is allowed (by exception to the rule).

"bicycle=use_sidepath" is also less "restrictive" than "bicycle=no" (forbidden): exception for - a small number of - residential houses that cannot be reached otherwise.
"compulsory" has some exceptions (bad cycleway, young children and their parents in Germany). 

This example is exceptional because the dead-end left turn is "blocked" by "bicycle=use_sidepath", dead-end right turn is "blocked" by "bicycle=no". Which is also bad mapping.
Therefore in this example I choose the most restrictive tag: exit:bicycle=no.

But (!) this tag is just an experiment (to resolve my issue on my Bicycle Map), no official proposal, not approved and not "de facto".

Best regards,
