Lifetime Warranty - What does it cover?

Are Khyber Racks suitable for off road use?
Absolutely. What good is a mountain bike rack that isn't?  

What kind of hitches are compatible?
2" for all sizes. The Two Pack is also available in 1.25". Your hitch should be mounted to the frame of the vehicle, not the body. Under no circumstances should the 1.25" kit be used on any rack other than the Two Pack. 

Can I carry kids bikes?
Most 20" bikes are compatible but may require an extra strap to hold the wheel at the front of the basket. The depth of the wheel baskets don't accommodate wheels smaller than 20".

How much do the racks weigh?

What about road bikes, fat bikes and e-bikes?
Our world revolves around mountain bikes, but yours doesn't have to. Our standard baskets accept Road Bike tires, and up to 29"x2.8" Plus tires. We also offer alternative Fat Bike baskets that will accept up to a 5" tire as well as a Road Bike tire.
E-bikes and 2002 V10's with Monster T's are approved. Any bike that weighs less than 24kg or 53lbs and fits inside the wheel basket properly is good to go.
