[Tagging] What access key for cargo bike ?

[Florimond Berthoux]

Hello,

What's the english word for this kind of bicycle
https://en.wikipedia.org/wiki/Freight_bicycle ?
It's to tag the access to this new kind of bicycle parking designed
for cargo bikes in Paris
https://framapic.org/w4zmjIvtoxim/1qsfbMKa1iVI.jpg
I'd like to have the word for all the kinds of those bicycle type not
just a part of them.
Taginfo doesn't help me here.

Tags would be :
amenity=bicycle_parking
[english for freight bicycle]=designated

The access key could be use also for other features like ramp,
barrier, elevator...
