To hold our mountain bike on top of our WJ we went with the Yakima FrontLoader (PN 8002103) bike rack. This rack does not require that you remove the front wheel from the bike. Our Kona 5.0 bike is heavy but was securely attached to the Jeep using the Yakima system. All this is also lockable with Yakima’s key systems. Only problem with our setup is that the handlebars of the bike are nearly 11 feet off the ground, so you have to be careful of overhead clearance.
