Overview
The Rockbros SKN is a non-electric 20-inch folding bike with a high-carbon steel electrophoretic-coated frame, Shimano 7-speed gearing and mechanical disc brakes. It folds to about 16.5 x 26.8 x 29.5 inches for storage or transport.
This is the one bike in this batch without a motor, aimed at riders who want portability over power. The listing's stated weight varies between the title (34.4 lbs) and the bullet specs (36.6 lbs), so treat the exact figure as approximate rather than precise. It arrives about 98 percent assembled and includes a rear rack rated for 66 lbs.
