"The Black Widow Aluminum eBike and Fat Tire Bike Carrier comes with a powder-coated steel hitch tube and aluminum carrier track. Built tough enough to transport motocross and dirt bikes, it easily holds one eBike or fat tire bike. The 47"" L ramp hooks over either end of the 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 400 lb. weight capacity, the 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” track is 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 bike is on the track, secure them firmly to the carrier with tie-down straps (sold separately) to ensure safe transportation to your destination."
