RockyMounts

Frequently Asked Questions

• Which RockyMounts rack is best for transporting e-bikes?

  The GigaWatt is purpose-built for e-bikes, with an 80 lb per-bike capacity, a 34–55" wheelbase range, and an included aluminum loading ramp for easier loading. It also has fender compatibility, an anti-wobble hitch bolt, and a robust 8mm square-link locking chain for security.
• How does the MonoRail compare to the GuideRail for carrying multiple bikes?

  The MonoRail is a versatile 2-bike platform (expandable to 3) that accommodates up to 5" tires and a wheelbase up to about 48", with 60 lb per tray and a lighter overall weight (MonoRail 2" ~44 lbs). The GuideRail is geared toward higher-capacity hauling—configurable for three bikes (rated 60 lb per bike but 45 lb in the 3-bike setup), includes brass washers on moving parts, a one-hand wheel-grab, stadium positioning, and an integrated 10mm locking chain for added security.
• What hitch receiver and vehicle clearance do I need for a RockyMounts rack?

  Most RockyMounts hitch racks require a 2" receiver, though models like the MonoRail Solo and WestSlope 2 include an adapter to fit 1.25" receivers. Plan for tilt and folding clearance—many models fold flat and tilt down (~30°) for hatch access—so measure from the hitch to your bumper/hatch to ensure proper access.
• How do RockyMounts racks secure bikes without touching the frame?

  RockyMounts uses a no-frame-contact design that secures bikes by the wheels, with ratcheting front-wheel hooks and wheel trays to prevent frame abrasion. Spacing (roughly 13"–15" between bikes) and 3" side-to-side adjustment keep bikes from rubbing, while locking hitch bolts, cable locks, and model-specific locking chains provide theft deterrence.
• What should I consider about tire width, wheelbase, and bike weight when choosing a RockyMounts rack?

  Match your rack to the widest tire, longest wheelbase, and heaviest bike you plan to carry: MonoRail handles up to 5" fat tires and wheelbases near 48", GigaWatt covers roughly 34–55" wheelbases and higher weights for e-bikes, and GuideRail supports 36–56" wheelbases with multi-bike capacity. Also check individual model weight ratings (e.g., MonoRail ~60 lb/tray, GigaWatt ~80 lb/bike, GuideRail ratings vary by configuration) to ensure compatibility with your bike and any accessories.
