Product Description
Eight bikes. All of them. The RSD8 is the largest rack in the RSD lineup — built for families, teams, and anyone who's been told they need a trailer. You don't.
Every position is rated to 80 lbs individually, with a 250 lb total capacity (350 lbs with stabilizer straps and anchors). The RSD8 accepts up to four OTB handlebar cradles, giving you the flexibility to carry a full mix of adult mountain bikes, kids' bikes, e-bikes, and everything in between — on one rack, in one trip.
Same symmetric dual-crossbar platform. Same powder-coated steel construction. Same foot-activated tilt latch and lifetime warranty. Just more capacity.

FAQ
Can I mix different cradle types on the same rack?
Yes — that's the whole idea. You can combine Standard Wheel, XL Wheel, and OTB Handlebar cradles in any configuration that fits your rack. Going on a trip with all adult bikes? All Standard cradles. Weekend with the kids? Add some Handlebar cradles. You configure it when you order, and you can swap cradles later in about 10 minutes.
What is the OTB Handlebar Cradle?
The OTB holds your bike by the handlebars instead of the wheels — two padded arms cradle the bar and the bike hangs vertically. Tire size doesn't matter, so it's the go-to for fat bikes over 5" wide, bikes with fenders, cargo bikes, kids' bikes, or anything that doesn't fit a standard wheel cradle. The configurator shows you exactly which positions support OTB cradles.
Can the rack handle e-bikes?
Absolutely. At 80 lbs per bike — and tested well beyond that — e-bikes are well within the RSD's capability. If your e-bike has wider tires, just spec an XL Wheel Cradle for that position.
What bikes fit in the XL Wheel Cradle?
The XL Wheel Cradle accommodates tires up to 26" × 5.0" or 27.5" × 4.5". That covers fat bikes, most plus-size tires, and heavy-duty e-bike tires. If your tire is wider than what the XL fits, the OTB Handlebar Cradle is your best option — it fits virtually any bike regardless of tire width.
Does the rack clear a spare tire on my Jeep or Bronco?
Yes. The RSD system is designed with rear-mounted spare tire clearance built in. No extra adapter or extension needed.
Does it include a hitch lock or bike lock?
Every rack includes a stabilizer clamp. The threaded locking hitch pin (to lock your rack to your car) and cable lock set to lock your bikes to your rack) are available as optional accessories.
