The incline from Genesis bicycles is just what the doctor ordered for on and off-road exercise and fun. Aluminum four-bar linkage suspension frame with a strong spring-loaded suspension fork, front disc brakes, rear linear-pull handbrakes, and a 21-speed drivetrain with Revo twist shifters from Shimano are the vitals. All this setup with a comfortable riding position featuring a padded saddle and rise handlebars will keep you out of the chiropractor's office. Ideal for adult males.
