I fail to see the value of questions that ask to identify a specific bike, often based on a single photo and little textual information. I'd like to suggest to make these off-topic.
- Even if a bike can be identified, the answer most likely has little value for the site as a whole.
- As the source of the identity is a photo and not a textual description, existing answers are hard to index and re-use.
A surprising number of these questions come from users with very low reputation - often as their first question. I don't know what to make of this.
