Overview
The Columba RJ26A is a full-size 26-inch alloy folding bike with an 18-speed drivetrain and both front and rear suspension. It folds down in around 10 seconds to a cubic space of roughly 38 x 14 x 29 inches for trunk storage or apartment living.
- 26 x 1.75 inch Shinko tires
- Alloy crank arms, hubs, rim, and kickstand
- Quick-release handlebar stem for compact folding
- Foldable bearing pedals
Who it's for
Suits commuters who want to stow a full-size bike in a car trunk or small closet without hauling around tiny wheels, and riders who value 18 gears for hills over the fastest possible fold. Not the choice for anyone wanting a bike ready to ride straight out of the box with zero adjustment.
Pros and cons
- Full 26-inch wheels ride closer to a standard bike than mini folders
- Front and rear suspension softens rough pavement
- Folds in about 10 seconds for trunk or closet storage
- 18-speed range handles moderate hills
- Wheels often arrive out of true and need a spoke wrench or shop visit
- Brake alignment, especially rear, can be off out of the box
- Folding mechanism didn't latch properly for at least one buyer
Performance notes
The Zoom Tracker 327V front fork and rear alloy spring absorb rougher pavement and light trail bumps better than a rigid folder, and the 18-speed shifter gives enough range for moderate hills. Owners who've logged hundreds to several thousand miles report the frame holds up well over time, though brake levers and cable adjustment are areas worth checking after assembly.
