I don't see a contradiction to the existing class:bicycle.
My opinion is not the one that counts. The best thing is to have a discussion with a wider group of mappers, e.g. in the forums or on the mailing list.

PS: Do you have a permit to use information from this website for OSM? The page states that "Information collected is not shared with other organisations for commercial purposes.", implying that it is not suited for OSM (i.e. compatible with ODbL)

Hi,
what is this about? Experience level for children? We do have several tags for classification already:
class:bicycle
class:bicycle:commute (this could fit)
mtb:scale (mountain trails)

I think the best solution is to make a mapping of your classification to existing tags. This allows existing software (e.g. bicycle routers) to use it right away.

If you want to define a new tag, best practice is to set up a wiki page first (make a proposal) and ask for feedback and discussion.

Hallo,
was hat denn das Tag an diesem Knoten zu bedeuten? node/2323682207

Gruss, Jan

Hi,
could you review these to objects? Tagging seems weird:
way/459433804
way/459446638

Jan

Hi,
"water_street" is a strange tag. Are you looking for water_tank:street?
Jan

Hi, welcome to OSM!
you invented several new tags here, for example these:
eastincome 红旗大街
northincome 礼贤路
northlane left|through|ped
southincome 红旗大街
southlane left|through|ped
westincome 红旗大街

OSM can only work with well-defined tags. Please have a look in the wiki how lanes and intersections are mapped.

Hi,
could you check this node?
www.openstreetmap.org/node/1081202325

hi = tu - not a valid tag
noexit =yes - there is a footway and a service way, but no way that ends here.

Jan

Hi,
could you check this building? It has two roof:shape tags.

way/432949109

Jan

Hi,
I found many buildings with a spelling mistake: 'demage' instead of 'damage'. Could you check this?

If you want, I can help correcting this.
Jan

Moin,
hier hat's 88 Mal "surce:maxspeed" mit fehlendem o.

Jan

Hallo,
in diesem Changeset habe ich Tags gefunden wie diese:

beschreibu=Mullbraunerde-Buchenwälder
deutsch=typischer Braunerde-Buchenwald
farbe=3.0
forstgrad=0.0
mischform=0.0

Dieses Tagging nutzt in OSM nichts, da es keine definierten Tags verwendet, die von Software ausgewertet werden können. Kannst du da noch etwas nacharbeiten?

Jan

Dürfen an dieser barrier auch keine Fußgänger oder Radfahrer durch?
node/4506685068

Hallo,
way/97672964
An diesem Weg hast du das Tag "zzz" gesetzt - kannst du das überprüfen?

Gruß, Jan

Hi,
I found the new tag ''bikeability" in your edits. I think you were looking for "class:bicycle"
class:bicycle=*

Jan

Hi,
I noticed these 91 nodes with tags from your GPS:
http://overpass-turbo.eu/s/kAn
I think they are not needed in OSM. Would you mind if I delete them?

Jan

Hi, I found 180 objects like this one:
way/442584084

Most of the "damage:" tags are misspelled and even contradicting each other. This makes the tags rather useless because they can not be shown e.g. on a map.

Wenn hier durchgehende barrier=kerb erfasst sind, müssten dann nicht auch die abgesenkten Bordsteinkanten an den Kreuzungen eingetragen werden? Die meisten Radwege führen hier ja nunmal nicht über Bordsteinkanten.

Hi,
you put a strange tag on this node, could you check it?

The health_specialty tag is already used a few times. A change should be discussed within the proposal / its Talk page.
