The Mammoth Mounts series of bike racks were designed primarily around transporting single crown mountain bikes however the racks will work with a variety of bikes including bmx bikes, gravel bikes, kids bikes and road bikes. This owners manual is intended to guide you through the safe setup and use of your rack.

Step 4 Install the upper and lower horizontal bars as shown Figure 3 in figure 3 using 1/2” x 3 1/2” bolts, nylock nuts and washers. The upper horizontal bar should be posi- tioned so that the hole spaced closest to the outside edge is on the right hand side of the rack and the angled face of the bracket is facing downwards.

Loading and Use Vehicle Mounting Use only on a vehicle equipped with a 2” class III or class IV hitch receiver with a minimum tongue weight capacity of 250lbs. To lower the center of gravity we recommend mounting the rack in the folded or collapsed position. If clearance allows always mount the bike rack in the deepest of the two 5/8”...
Folding the Rack It is very important that all bikes are removed from the rack before attempting to fold the rack at the center pivot. Simply remove the 1/2” pin from the center pivot while supporting the upper mast. Once the pin is removed gently lower the upper mast and place the pin through the pivot plates and through the lower mast at the second pin hole location on the pivot plates.
The vehicle’s speed must always be adjusted to the load being carried and the current driving conditions, such as the road type, road quality, wind conditions, tra c intensity and applicable speed limits, but must under no circumstances exceed 130 km/h. Applicable speed limits and other tra c regulations must always be observed.
