This is a good .biz domain name.
But I find it less valuable than the singular, "bike".
Since the .biz gTLD is not popular as at used to be, it is even less valuable.
Can be used for "bikes" related website and serve as inexpensive alternative to .com/.net/.org.
Resell price: high $xx to low $xxx
End user price: high $xxx
Good enough to fetch $500. But little marketing is needed due to .biz.
Try with domaining.com newsletter for just $10 to 15 to reach more audience to your lisiting.
IMHO
