Description
Open-box customer return - Unridden.
This bike was returned because the original customer felt the bike was too tall for their riding preference. The bike was opened but not ridden before being returned.
Because the original packaging has been opened and the bike has gone through return transportation, the box and bike may show minor packaging, handling, or cosmetic marks. This does not affect normal functionality.
A great opportunity to purchase a Greatwork M8 at a significantly reduced price.
