Premium Steel Folder, Serious Commuters
You want a budget folder — this is the premium steel option.
This pedal-only folding bike uses a LUG-brazed 4130 chromoly steel frame — a hand-built construction method more associated with premium road bikes than budget folders. It pairs a 9-speed drivetrain with hydraulic disc brakes (160mm front / 140mm rear) for stopping power that outperforms most folding bikes at this price, at 11.7kg.
