The bobbed fenders, Enforcer aluminum wheels and 12-inch mini-ape hanger handlebars give the Freewheeler three-wheeler a stripped-down, garage custom look. But its optional trike-specific Reflex Defensive Rider System with tire-pressure monitoring is something you can only get from the H-D factory. All powered by the Milwaukee-Eight 114 V-Twin engine, this trike transcends comfort on its 49-millimeter front forks and easily adjustable rear suspension.
