WheelWally. A bike rack for trucks. Compact, easy to install, very secure. Attach your road or mountain bike quickly, without removing your wheel. Fits wheel sizes: 26″, 27.5″ , 29″, and 700c. A standard (non-track) WheelWally installation shown with a 29er wheel. H.b.a.’s are inserted into 1/4″ holes drilled in the rail. T.b.a.’s are inserted into 1/4″ holes drilled in the bed. Note that the toe board is elevated above the bed. A complete installation showing the WheelWally and the Off-road kit. This short bed (5′-8″) truck uses a bed extender so the bike will fit. Two bikes in a long bed (8′-0″) truck. No bed extender is needed. The Off-road kit (O.R.K.) is optional, but highly recommended. Detail showing “L” end of the Off-road kit. The O.R.K. was designed to eliminate lateral bike movement. The WheelWally works for road bikes too! Lock your WheelWally and bike to a strong tie-down point in your bed. Cable not included. You must use the “Off-road kit” or the “Rear wheel tie down kit” whenever you transport your bike. The “Rear wheel tie down kit” (R.W.T.D.K.) keeps the rear wheel of your bike “planted” to the truck bed. The R.W.T.D.K. does NOT resist lateral movement and should only be used with light bikes like this one. We do NOT recommend this installation! Use the O.R.K. instead for increased stability on rough roads. Super strong Omni straps hold this fat bike in place. A Cannondale bike with a “Lefty” fork. This bike has a fixed axle, instead of a quick-release skewer. This is a Toyota “deck rail” installation. H.b.a.’s slide into the track. T.b.a.’s are inserted into 1/4″ holes drilled in the bed. Toe-boards can be oriented like this, or spun 180 degrees, whichever works best for your layout. A section of Toyota “deck rail”. Toyota h.b.a. track washers fit horizontally. The “no-slip”nuts are aligned vertically. This is a Nissan “utili-track” installation. No drilling is required for this installation. H.b.a.’s and t.b.a’s slide into the “utili-tracks”. The “utili-track” can be capped with a rubber strip (provided by Nissan). A section of Nissan “utili-track”. Nissan h.b.a. track washers fit vertically . The “no-slip” nuts are aligned vertically. We include optional hardware to allow for tool-free hba installation and removal. When using a bed extender, store your gear in the cab of your truck, not in the bed. The O.R.K. keeps your bike fixed in place, all the time.
