The Explorer has been one of Jamis' best-selling bikes ever since its introduction in 1982. Originally designed as a mountain bike, the Explorer has since evolved into a very practical and very comfortable bike. The Explorer's aluminum frame feels lightweight and nimble with a step-thru design that makes getting on and off a breeze. The long angle-adjustable stem and 80mm rise handlebars offer an upright riding position that's easy on neck and wrists. The 21-speed Shimano twist-shifting drivetrain with Altus front derailleur and 14-34 Mega-Range freewheel make hill climbing easy. And, Tektro's CL530 brake levers offer slip-resistant, shock-absorbing inserts on the finger contact points for more secure, comfortable braking that enhances control, even on hills.
