I’ve been testing a folding commuter bike, the Dahon Jack. This is a good quality bike that feels solid when riding. I like the ergonomic grips on the handlebars and the full-size 26 inch wheels. I get a lot of flats, so the bike’s Schwalbe Big Apple tires were a welcome inclusion. Dahon says that these tires, which include Kevlar anti-puncture lining, offer lower rolling resistance than thinner tires.
The Dahon Jack fairly light at 13.6 kg (30 lbs.), and fold down easily to 38 x 69 x 91 cm (14″ x 27″ x 36″).
