Most of the platform is pre-assembled which makes mounting and adjusting easy. It has a total weight of 79 pounds, with most of the parts being steel tubing that is light. An installation manual is, however, provided for detailed instructions on how the parts fit.
Basically, you need a wrench and an extra pair of hands to get KAC Overdrive Sports K4 into position.

Note, there are washers, bolts, and knobs for fastening the different joints together.
The KAC Overdrive Sports K4 bike carrier is designed to conveniently hold 2 or 4 bikes. To split the rack into a 2-bike version, you just need to unfasten 2 bolts to remove the hitch tube extension.

You should also make use of the safety straps that come with the KAC Overdrive Sports K4 rack for your bikes not to slide off their positions. Nevertheless, the platform is designed for adult-size bikes with wheels of 24 inches or more.

Why The KAC Overdrive Sports K4 2” Platform Bike Rack is Unique
The KAC Overdrive Sports K4 2’’ is a sturdy platform bike rack that is made from heavy gauge powder-coated steel. This is a versatile hitch-mounted rack that can carry 4 bikes of up to 60 lbs each. The rack can also be adapted into a simpler configuration to carry 2 bikes.
In the folded position, the rack is just 18 inches long and about a foot long when fully deployed. Play between the rack and the receiver is eliminated by tightening a lock pin. Bikes are well spaced and held on padded hooks to avoid wear and tear from rubbing against each other and the rack.
Included in the package are safety straps and keys for locking the patented anti-wobble hitch system and the top adjustment knob. You also get extra
Even with its versatility and top-notch security features, the KAC Overdrive Sports K4 is disadvantageous in some aspects. For example, the rack only works on a 2’’ hitch while competitors like the Apex XT Bike Hitch rack are adaptable for both 2” and 1.25” hitches.
The item also requires additional accessories (sold separately) when carrying low y-frame and step-through bikes. It is however very ideal for transporting bikes with fenders since you can secure bikes on adjustable top frame hooks that are padded. A reflector is also provided to ensure other road users can see the rack at night and during poor visibility weather.
When transporting your bikes for an out-of-town exercise, you need a rack that is reliable. The KAC Overdrive Sports K4 2” hitch platform bike rack is just the carrier you need. This is a sturdy rack built from steel tubing with intricate parts to keep your bikes secure, even on a bumpy road.
As a precaution though, when on the road, it helps to keep checking the tightness of the locking hitch pin, safety straps, and the reflector. The quick-release tilt is another feature that needs to be operated delicately.
At 70 lbs unloaded and 310 lbs when loaded with 4 bikes, the rack is heavy. Safe operation calls for supporting the weight when tilting and dropping the rack to access the rear cargo access. So, apart from being extremely cautious, always have a friend help to tilt the rack, especially when it’s fully loaded.
