"The Black Widow Aluminum Double eBike and Fat Tire Bike Carrier comes with a powder-coated steel hitch tube and dual aluminum carrier tracks. Built tough enough to transport motocross and dirt bikes, it easily holds up to two eBikes or fat tire bikes. The 45.5"" L ramp hooks over either end of each carrier for simplified roll-on, roll-off operation; no heavy lifting required! When not in use, the ramp stores directly on the hitch tube with a bolt and wing nut. With a 600 lb. weight capacity (400 lbs. max per track), each overbuilt carrier track is able to support even the heaviest of eBikes without requiring the removal of the battery, and unlike most standard bicycle carriers, the 5.5"" tracks are wide enough to accommodate fat tires easily. An anti-tilt bracket is included to reduce sway and wobble while the carrier is in motion. Once the bikes are on the track, secure them firmly to the carrier with tie-down straps (sold separately) to ensure safe transportation to your destination."
