Google's N-Gram viewer shows a slight advantage for Bicycle over Bike in English:


So I would be prone to implement this.

> Fair enough. And you point about this becoming a bigger problem if schema keeps growing is a sensible one. We either end up namespacing by adding words into names and maintain the flat schema, or we do something to structure it and break what we said before. In the former case, we start relying on tools to help out more… which puts an onus on us to help them out more…

So in this case, I would suggest to stick with the names in the current proposal. Prefixing all properties with "vehicleXYZ" will 
- make them cumbersome to use
- be in contrast to the naming patterns in use for schema.org and
- while it reduces the risks for collisions, it makes it harder to spot similarities and to reuse properties.

Also, they are designed to be free from collisions with the existing vocabulary.

Can I infer from your mail that your are in general fine with the proposal, despite these two issues?
