A standard car bike rack is the first thing most new RV owners try, and it is usually the first thing to break. A motorhome or trailer rides much higher, much longer, and takes far more abuse over a washboard road than a sedan ever will, so a rack that flexes happily on a crossover starts creaking and rattling behind an RV.
That is why the best bike racks for RVs are a separate category with their own rules. We compared ten racks across every mounting point an RV actually offers: a rear hitch receiver, a square steel bumper, a roof-access ladder, and the A-frame tongue of a travel trailer. We weighed the numbers that decide whether a rack survives the trip, starting with per-bike weight capacity and receiver ratings.
Our method was straightforward. We read every spec block, then read the owner reviews closely, because the pattern of complaints tells you more about an RV rack than the marketing photo ever will. Bounce, vibration, spare tire clearance, and how a rack behaves when it is loaded with two 70 lb e-bikes were the deciding factors.
One thing worth saying up front: you are not buying a rack for the car you tow with, you are buying it for the trailer behind you. Everything below reflects that, including the fitment section, which covers the tongue weight math that most roundups skip. If you are still choosing gear for the cockpit, our guide to the best backup cameras for RVs covers the other end of the rig.
All ten racks below are shown with the same four questions in mind: how it mounts, how many bikes it carries, how heavy those bikes can be, and who it suits best. Ratings and review counts come straight from the verified buyer listings, not from our own testing rig.

35 lb per bike
Hitch or 4.5 inch square bumper mount
Folds up for rear access
Limited lifetime warranty
This is the rack we kept coming back to across a month of comparing specs and owner reports. The Traveller XC2 carries two bikes at 35 lb each, sits in a full-size 2 inch receiver pin rather than a flimsy adapter, and it is explicitly marketed and sold as RV approved. That last detail matters more than any spec line on the box.
Owners with thousands of miles behind them describe a rack that assembles in minutes and does not develop frame bounce over long highway runs. The ratcheting frame hooks lock with any standard padlock, which is the cheapest theft deterrent you can add and the one most thieves look for first.

Two details make it stand out. The included 2 inch bumper adapter lets the same rack move to a 4.5 inch continuous welded steel RV bumper, and the upright center bar folds flat so you can reach a rear door or a storage hatch without pulling the whole unit off.
The XC2 wants a 2 inch Class 3 receiver or a 4.5 inch square steel bumper. With a spare tire on the bumper, the receiver is your only option short of an extension bar, and handlebars can still rub the trailer wall in tight turns.
RV-approved racks are built with heavier tubing, tighter welds, and hardware that tolerates the constant low-frequency oscillation a long trailer puts into its rear end. The XC2 is 39 pounds of steel, and that weight is the point. It is the reason it does not develop the wobble that lighter racks show after a season of washboard roads.
One owner note: the supplied hitch pin bolts in rather than locking, so add your own locking pin and a cable through both frames if theft resistance matters to you.

For a family of two carrying standard bicycles, this is the rack we would buy first, because it covers the two most common RV mount points in one product.
Folding ladder mount design
Holds 2 bikes
60 lb combined limit
9.8 pounds
If your rig has no rear receiver and no steel bumper worth clamping to, the ladder is often the only place left, and this is the rack most owners land on there. It folds flat, holds two bikes, and installs without tools on most standard RV ladders. Under 10 pounds, it is also the easiest rack here to remove and stow.
Owners across more than 1,400 ratings praise simplicity rather than strength. It suits kids bikes, beach cruisers, and folding camp chairs, and it does exactly what it promises without any fuss.

The honest limit is the 60 lb combined rating, roughly 30 lb per bike. Fine for standard bicycles and light kids bikes, and no solution at all for a 62 lb fat-tire e-bike.
The recurring complaint in the reviews is that the rubber straps and braces slide downward under sustained weight and road vibration. The fix is unglamorous: mark the strap positions with paint pen before the first drive, and re-check them at every fuel stop. Ratchet them down firmly rather than pulling them to a hard stop, which stretches them faster.
Before mounting anything to an RV ladder, confirm the ladder itself and the two rails it attaches to are rated for the combined weight of the rack and the bikes. A ladder is often a structural convenience on a travel trailer rather than a load-bearing frame member. This is a mounting base, not a cargo deck, and treating it like one is how people end up with a bent ladder rail.
Check that the pre-drilled bolt hole is present before you start, since a few units have shipped without it. A single drilled hole and a short bolt is a two-minute fix.

For two standard bikes on a rig with no hitch, this is the cheapest sensible answer in the market. It is not the strongest rack here, but matched to the right job it does the job well.
A-frame tongue jack mount
2 bikes
80 lb total capacity
36.4 pounds
This rack answers a problem most RV racks ignore: the rear of a travel trailer is usually already full. The Jack-It Double clamps to the A-frame over the tongue jack and puts the bikes at the front of the trailer, over the axle, where there is the least bounce in the entire rig. Owners who switched to it report the calmest, most solid ride of any rack they have used.
The hardware list is unusually complete. BikeWing arms, foam pads, SwayControl curved cradles, rubber straps, and NoMotion pins come in the box, and the pins can be padlocked so the bikes are not a target at a stoplight. Capacity is rated at 80 lb total, which comfortably covers a pair of mid-weight e-bikes.

The trade is height. Bikes sit noticeably higher than on a bumper rack, and lifting a loaded e-bike to that position is a two-person job. Owners who planned for this with a step ladder and a helper report complete satisfaction; owners who tried it solo end up sore or scratched.
The reason for the stability is simple physics. An A-frame mount places the load directly over the trailer axle instead of far behind the rear axle, where a bumper or hitch rack acts like a long lever arm. Less leverage means less oscillation, and less oscillation means your paint, your bottles, and your shock seals all last longer.
It is also the only mount in this roundup that leaves the whole rear of the trailer free, which matters for a family hauling coolers, a grill, and firewood alongside their bikes.
This system sits over the tongue jack, so confirm the style of jack on your trailer. It mounts on top of a conventional jack and over a power tongue jack, but it can block the emergency manual override on some power jacks, and it is not compatible with side-mount hand-crank jacks. Check before you order.

If your family of two wants a loaded rear cargo area and stable bikes at once, this is the most thoughtfully engineered rack here. Budget a helper and a step ladder, and read the instructions twice.
Bumper mount
2 bikes
30 lb per bike
Fits 4 to 4.5 inch square bumpers
For rigs with a wide 4 inch to 4.5 inch continuous welded steel bumper and no usable receiver, the QPRBM2R is the workhorse pick. It carries two bikes at 30 lb each, spreads the load across the bumper face rather than one point, and costs a fraction of a hitch rack. Owners also use it as a cargo carrier for camp gear.
Build quality surprises people. The all-steel, powder-coated frame feels more substantial than the low price suggests, and owners report a stable ride with bikes a little past the 30 lb rating.

If your trailer carries its spare tire on the rear bumper, this rack will not clear it in most configurations. You either relocate the spare to a swing-away carrier under the trailer, or you move to a hitch or tongue mount. Measure the gap between the bumper face and the trailer body before buying, and check the tire wells against your bikes’ width.
The wheel wells are fixed, so both bikes need roughly the same wheelbase. Pairing an adult bike with a 20 inch kids bike will not fit well, and fat tires or wheels over 29 inches will not fit at all. For mixed-size bikes, the four-bike rack later in this roundup handles that better.
The center stabilizer post included in the box is the one part most owners modify or remove. As shipped it sits too short and too far from the bike slots to do useful work.

This is the pick for a couple on a small trailer with a solid steel bumper. Know your wheelbase before you order.
Bumper mount
1 to 4 bikes
30 lb per bike,120 lb total
Limited lifetime warranty
Four bikes on one bumper is the configuration most families need and most racks cannot deliver. The Swagman 80600 takes one to four bicycles at up to 30 lb each, and the central upright bar is the piece that makes it work: it braces the middle of the load so bikes do not sway into each other over a long tow.
Both 6.5 inch and 8 inch U-bolts are included, so it clamps to 4 inch and 4.5 inch square steel bumpers without a separate adapter. The powder-coated steel and the limited lifetime warranty put it ahead of cheaper bumper racks in terms of how long owners expect to keep it.

Four bikes plus a steel rack adds real weight to the rear bumper of a travel trailer, and it has to fit inside the trailer’s remaining payload. Check the payload sticker inside the trailer before loading, not after. If the numbers are tight, carrying two bikes is cheaper than a suspension repair.
These bikes are held by their tires rather than by a frame clamp, which is fast to load and works with nearly any frame shape, including step-through and cargo bikes. The trade is that the frames need their own tie-down straps, and those are not included. Buy a small pack of soft ratchet straps before the first trip.
Check the spare tire position too. On many fifth wheels the spare sits high enough that the outer slot is usable, but on smaller trailers it can block the fourth position entirely.

For a family of four on a bumper-equipped trailer, this is the most capable rack in the roundup for the money.
Creates a 2 inch receiver on the A-frame
Supports 100 lb
Fits 14 to 55 inch frame widths
Sometimes the answer is not a better rack but a better place to hang the rack you already have. The CC-275 mounts across the A-frame and creates a raised, true 2 inch receiver at the tongue, which is the smoothest-riding point on an entire trailer. Pair it with any RV-approved 2 inch platform rack and you get hitch-rack stability on a trailer that has no hitch of its own.
The adjustable vertical posts fit A-frame widths from 14 to 55 inches, covering a wide range of trailer and fifth wheel tongues. It supports 100 lb, enough for a lightweight rack plus two standard bicycles.

This is the one practical note owners repeat more than any other. The bunk sits above A-frame propane tanks, and if your trailer has rigid plastic tank covers, the LP valves can become unreachable for refilling once the bunk is installed. Many owners convert to soft vinyl or flip-top hard covers as part of the install. Check your tank cover style first.
The CC-275 ships as a mounting structure only, so you still need a separate RV-approved 2 inch receiver bike rack. If you already own one, this makes it work on a trailer with no hitch. Starting from nothing, a complete system costs less in total.
At 44 pounds, it is a heavy addition to the tongue. Work that into the same payload check you would run for any other rear load.

For owners of a trailer without a rear receiver who already own a hitch rack, this is the cleverest solution here.
Hitch mount
2 e-bikes
80 lb per bike,160 lb total
Limited lifetime warranty
If your bikes weigh 60 lb or more, most racks on the market simply are not for you, and the Hollywood RV Rider is built specifically for that load. It carries two e-bikes at up to 80 lb each, a 160 lb total, with heavy-duty wheel holders and frame grabbers that stop a heavy frame from twisting while the frame grabbers take the load instead.
It posts the highest average rating in this roundup, and the reason shows up repeatedly in the reviews. Buyers stop worrying about whether their expensive bikes are going to be safe behind the rig, and the locking security cable plus a hitch tightener answer the theft question that comes up constantly in RV forums.

RV owners report this rack was reinforced for rough towing conditions, which matches the numbers. The heavy-duty receiver tube and alloy steel construction are sized for a load that would bend a standard car rack.
Fat-tire bikes are within spec, which is worth noting because very few racks in this category claim it.
At 56 pounds empty, this is a two-person lift into a receiver, and loading two 70 lb e-bikes onto the tray is definitely not a solo job. It also requires a Class 3 hitch with a 2 inch receiver, which rules it out for lighter tow vehicles and for many travel trailers. Budget for a proper hitch, not just the rack.
The wheel holders add length behind the rig, so a bumper-mounted spare tire trailer still needs clearance. If your e-bikes run past 80 lb each, you are at the edge of the rating rather than comfortably inside it.

For riders carrying two heavy e-bikes behind a motorhome or a flat-towed vehicle, this is the correct answer. For standard bikes, it is more machine than you need.
Bumper mount
1 to 4 bikes
140 lb total capacity
Tie-down straps sold separately
This rack solves the family problem better than the other four-bike bumper option. The Rage Powersports BC4BM ships with three 2 inch and one 2.25 inch tire wells, which is what makes it practical to pair an adult bike with a small kids bike on the same rack.
Once assembled, owners describe an extremely stiff tubular steel frame that shrugs off four heavy bikes without bounce, and the 140 lb total is the highest figure of any bumper rack here.
Nearly every complaint about this product happens before the first drive. Instructions are confusing, the pre-drilled holes frequently fail to line up, and straps are not included so you need to buy them separately. Owners who push through assembly report satisfaction with the finished result, which is the honest summary of this pick.
It needs at least 2 inches between the bumper and the trailer body, and some fifth wheel bumpers sit too close for that. Measure it rather than assuming. It also adds roughly two feet of length behind the camper, which matters in a tight campground loop or at a storage facility.
A handful of owners upgraded the included metric hardware to SAE grade 8 bolts, and a few reported early surface rust at weld points. Both are worth a coat of protection before a first long trip.
The 4.0 average rating reflects those pre-use friction points rather than a rack that fails under load. If you are willing to spend an evening with the instructions, the finished rack is genuinely strong.
Ladder mount
1 bike
50 lb per side,100 lb total
2.3 pounds
Sometimes a full bike rack is more than the job requires. The Clamp-N-Carry holds one bike, or four or more folding chairs, and at 2.3 pounds you can take it off in seconds and stow it in a storage compartment. It is built from glass-filled nylon with UV inhibitors and zinc-plated hardware, both chosen for a life in full sun on a rear ladder.
The detail that separates it from every other ladder rack here is the padlock. It accepts a standard 1/8 inch padlock, so you can secure the rack itself to the ladder rather than just securing the bike. Included adapters let it fit most 1 inch and 7/8 inch diameter ladders, and it mounts without tools.

A solo traveler, a couple who rides on alternate days, or anyone who wants a place to put camp chairs will find this more useful than a two-bike rack. It swings clear for ladder access, which is the point of putting it there. Buyers who expected a two-bike carrier are the ones disappointed.
The 50 lb per side rating puts heavy e-bikes out of range, and the plastic cradle straps do loosen over a long trip, so re-tension them at fuel stops. Bike frames can also sit close to the ladder or the trailer wall, which limits the width of handlebars that fit comfortably.
Fit and security both depend on the shape of your specific ladder, so check whether your ladder style needs one of the included adapters before you order.

Hitch mount platform
2 e-bikes
180 lb total capacity
Folds flat and tilts down
The Soarify is the answer for riders carrying e-bikes who do not want the outlay that a premium e-bike rack demands. The alloy steel platform is rated at 180 lb for two bikes, which is more headroom than most racks at this level offer, and owners carry a pair of e-bikes on it without complaint.
It folds flat against the vehicle when empty and tilts down for rear access without removing the bikes, which are the two practical touches owners praise most. Assembly takes minimal tools, and the whole unit weighs 34 pounds empty, light enough for one person to lift into a receiver.

It is a wheel-mount platform, so the tires do the holding rather than a frame clamp. That makes loading fast and it is indifferent to frame shape, which suits step-through, folding, or fat-tire frames. Frames stay exposed, so add a soft strap across each in places where you leave the rig unattended.
The 2 inch receiver requirement rules it out on many travel trailers and on any trailer without a tongue-mounted receiver, so check fitment first. It is also the shortest warranty in this roundup at one year, and hitch-mounted racks of any kind add weight behind the vehicle and reduce clearance over uneven ground, which matters on a rough forest road.
Judged against the Hollywood RV Rider, this is the value option. Judged against a standard car rack, it is a different machine entirely.

Most failed RV bike rack purchases are not bad racks. They are racks that never should have been ordered for that particular rig, and the three things that decide it are receiver size, tongue weight headroom, and whether a spare tire is in the way. Run through these five checks before you click buy.
Motorhomes and many fifth wheels use a 2 inch Class 3 receiver, but plenty of travel trailers and older rigs use a 1 1/4 inch receiver. Almost every hitch rack in this roundup requires 2 inches, and the ones that accept a 1 1/4 inch receiver usually need a separate adapter that reduces capacity. Measure the opening across the inside before anything else.
This is the point that catches experienced RVers out, and it is the single most misunderstood number in this whole topic. A receiver commonly carries a 350 lb tongue weight limit even when the hitch ball itself is rated far higher. An owner on a Good Sam forum put it plainly: if your receiver has a 350 lb limit, then the load on that receiver is limited to 350 lb, even if the hitch is rated much higher. A loaded bike rack counts against that number, so a full four-bike bumper load can eat into your remaining payload significantly.
Yes, tongue weight applies. Add up the weight of the rack itself plus every bike, and that total comes off your available receiver and payload capacity. A 41 lb four-bike rack carrying four 30 lb bikes is roughly 160 lb riding at the back of your trailer, which is not a small number against a typical 350 lb receiver limit.
Overloading the receiver shows up as sway that gets worse with speed, receiver flex, hard braking that pushes the trailer around, and eventually a cracked weld or a bent ball mount. If your tongue weight is already near its limit, carry two bikes instead of four.
A spare tire mounted on the trailer bumper physically blocks most hitch racks and many bumper racks. Your options are relocating the spare to a swing-away carrier under the trailer, using a hitch extender to move the rack back, or choosing an A-frame mount that ignores the bumper entirely. Owners on RV forums consistently identify spare tire clearance as the number one fitment problem they hit.
A hitch extender solves clearance by putting the rack further from the receiver, and it carries two penalties. It typically cuts your allowable tongue weight by about half, and it increases the leverage on the receiver rather than reducing it, which means more flex and sway, not less. Use one when you have no other option, and re-run the tongue weight math with the reduced figure before you load it.
Once fitment is settled, three decisions drive the rest of the purchase. Here is how each one actually plays out on an RV.
Hitch mount is the default for motorhomes and fifth wheels with a 2 inch receiver. It is the most stable, most widely supported, and the easiest to add anti-wobble hardware to. It also puts the load furthest behind the axle, so sway and bounce are at their worst here.
Bumper mount racks clamp to a 4 inch or 4.5 inch continuous welded steel bumper with U-bolts. The broader contact area actually rattles less than a hitch rack, and there is no tongue weight conversation to have, but you need a steel bumper, a clear path behind it, and a free hand to load bikes.
Ladder mount racks are the cheapest and the easiest to remove, and they are the only option on some small trailers. The governing question is not the rack, it is whether the ladder and its rails are rated for the combined load.
A-frame and tongue mounts put the bikes at the front of a travel trailer, over the axle, where there is the least bounce in the entire rig. They free the rear for cargo and give the calmest ride, at the cost of loading height and the need to check your tongue jack and propane tank access.
Standard adult bicycles typically weigh 20 to 30 lb, kids bikes run 25 to 35 lb, mid-weight e-bikes land around 50 to 65 lb, and heavy fat-tire e-bikes can exceed 70 lb. A rack rated at 30 or 35 lb per bike is completely fine for the first group and useless for the last two. Owners regularly report 62 lb and 70 lb e-bikes that simply will not work on a conventionally rated rack, which is why the e-bike picks in this roundup are rated at 80 lb or higher.
Leave headroom. A rack rated exactly at your bike weight has no margin for a pump, a battery, a bag, and road grime.
Integrated locking pins, padlock-ready ratcheting hooks, and locking security cables all help, and they are worth having. But bikes visible on a rear rack are a target in stop-and-go traffic, and no product feature fixes that on its own. The practice that does is a cable or chain through both wheels and the frame, anchored to the rack or the receiver, every single time you stop. Owners who do this consistently report it removes the problem entirely.
Platform and wheel-mount racks hold bikes by their tires, which makes them fast to load, tolerant of any frame shape, and friendly to step-through and fat-tire frames. Hanging racks grab the top tube, are lighter and cheaper, and struggle with some frame shapes. For an RV, platform is the more forgiving choice because bike geometry varies more than people expect.
Foldability is a comfort feature more than a safety one. A rack that folds up or tilts down, like the XC2, the Hollywood RV Rider, or the Soarify, keeps your rear door and storage hatch usable while the bikes are off. On a small trailer with a rear entry, that matters every single day.
These are the checks that separate a rack that lasts a season from one that survives years of towing.
Confirm RV-rated certification. Racks sold for cars are not tested for the bounce and vibration profile of a long trailer. Look for explicit RV approval from the manufacturer.
Respect the receiver rating, not the hitch rating. Every pound on the rack counts against your tongue weight and payload capacity. Check the receiver stamp before loading.
Never use a fabric bike cover while driving. A cover acts as a sail. Owners report straps snapping and bike frames bending when a wind-catch cover was fitted to a rear rack, and one owner damaged a trailer window the same way. Cover the bikes only when the rig is parked.
Check every strap at every fuel stop. Rubber straps and webbing creep under sustained vibration. Re-tension rather than replace, and re-mark the positions before the first drive.
Chain the frame, not just the wheel. Lock through both wheels and the frame. Thieves know the difference.
Do not invert bikes on a ladder rack if they have air or oil shocks. Turning a bike upside down drains the shock and can damage the seal.
Verify the ladder is rated before drilling into it. The rack is the least of the load if the rails are not structural.
Re-check clearance at the first full tank. Handlebars, pedals, and the spare tire all behave differently once the suspension is loaded.
A 2 inch Class 3 hitch-mounted platform rack is the best bike rack for a motorhome. Motorhomes sit highest and transmit the most bounce, so you want an RV-approved rack with anti-wobble hardware, a per-bike rating with real headroom, and lockable hooks. The Swagman Traveller XC2 fits a 2 inch receiver and a 4.5 inch square bumper, carries two bikes at 35 lb each, and folds up for rear access. For heavy e-bikes, the Hollywood RV Rider handles two bikes at 80 lb each.
Some Thule racks carry RV approval and some do not, so check the specific model’s specifications rather than the brand. Look for an explicit RV rating or a hitch-mounted platform design rated for 2 inch receivers. A rack marketed only for cars is generally not tested for the bounce and vibration profile of a long trailer, and the wrong rack can flex, rattle, and eventually fail behind an RV.
Most RV bike racks need a 2 inch Class 3 receiver, which is standard on motorhomes and many fifth wheels. Travel trailers and older rigs often have a 1 1/4 inch receiver, and most racks will not fit it without an adapter that reduces capacity. Measure the inside opening of your receiver before ordering, and check the receiver’s tongue weight rating at the same time, because the receiver rating governs your load, not the hitch rating.
Yes. The weight of a bike rack plus every bike on it counts against your trailer’s tongue weight and payload capacity. A four-bike rack at 41 lb carrying four 30 lb bikes puts roughly 160 lb behind the trailer. Since many RV receivers are rated around 350 lb, a full load can use up much of your remaining capacity, which is why owners check the payload sticker before loading four bikes.
You get sway that worsens with speed, visible receiver flex, trailer push in hard braking, and eventually a cracked weld or a damaged ball mount. If a hitch extender is involved, allowable tongue weight is typically cut by about half and leverage on the receiver increases, which makes flex worse rather than better. The fix is carrying fewer bikes, not a heavier-duty rack.
No bicycle rack is covered in transit, and you should not cover bikes while driving. A fabric cover acts as a sail in crosswind, and owners report snapped straps and bent bike frames from wind-catching covers on rear racks. Cover your bikes only while the rig is parked. If you want weather protection while camping, a rack with a folding tray plus a separate lockable cover applied at camp is the safe approach.
It depends on the rack and your receiver, and the lower number always wins. Racks in this roundup run from 30 lb per bike on bumper mounts to 80 lb per bike on e-bike-rated platforms, with total capacities from 80 lb up to 180 lb. Your receiver’s tongue weight rating is the hard ceiling regardless of the rack rating, so check that stamp before you choose a rack based on its own capacity.
Folding ladder-mount racks like the Camco 51492 and the Camco Clamp-N-Carry are the standard options. The 51492 holds two bikes with a 60 lb combined limit, while the Clamp-N-Carry holds one bike at 50 lb per side and doubles as a chair rack. Before mounting anything, confirm the ladder and its two attachment rails are rated for the combined weight of the rack and the bikes.
If you want one answer for a typical motorhome carrying two standard bikes, the Swagman Traveller XC2 is where to start. It is RV approved, it fits both a 2 inch receiver and a 4.5 inch square bumper, and it is the only pick here that covers both common RV mount points in one rack.
If you ride heavy e-bikes, stop reading the ratings below 60 lb and go to the Hollywood RV Rider for two bikes at 80 lb each, or the Soarify platform if you want more total capacity for less. If you own a travel trailer with no usable receiver, the Lippert Jack-It on the A-frame gives you the calmest ride and frees the entire rear, while the Swagman 80600 covers four riders on a steel bumper.
If your budget is tight, the Camco 51492 on a ladder is the cheapest sensible way to get two bikes off the interior, and the Camco Clamp-N-Carry does the same job for a single bike at a couple of pounds of weight.
Before any of them, measure your receiver, check the tongue weight stamp, and look at where your spare tire lives. For the rest of your rig, our pick of the best storage racks for dumbbells covers another corner of the same problem: finding a home for the gear you bring along.
