Tow-bar rack load compatibility
Enter the measurements above to calculate tow-bar rack load compatibility.
How the calculation works
V16 calculation: countPass=bikeCount≤rackRatedBikeCount; rackBikeLoadPass=totalBikeWeight≤rackRatedBikeLoad; towbarLoad=rackWeight+totalBikeWeight; towbarPass=towbarLoad≤towbarVerticalLoadLimit; overallPass=countPass AND rackBikeLoadPass AND towbarPass.
Worked example
Example: Bikes = 2; Total bike weight = 45 kg; Rack weight = 18 kg; Towbar vertical load limit = 75 kg; Rack bike load rating = 60 kg; Rack rated bike count = 4. Result: Fits; Towbar Pass = Pass; Towbar Load = 63 kg; Rack Bike Load Pass = Pass.
