Need help with rack size, vehicle fit, bike fit, tire sizes or other questions? 

If you can’t find your answer here send us a message

The first obvious question is how many bikes do you plan on hauling?  Many customers consider buying a rack that hauls one more than their current need.


Will the rack primarily be on your vehicle or mounted in the garage?  Many leave the rack on their vehicle all year long and many leave it in the garage and bring it out for weekends and trips.  If it's on your vehicle all the time we’d tend toward recommending the size you need and not up sizing.   But the final choice is up to you here’s what you need to know about our different rack sizes and the spacing available on each rack along with things to consider with different vehicles.


  • VelociRAX require a class III two inch hitch with a capacity of 500 lbs.

  • All VelociRAX models can carry 230 lbs. (bike weight)

  • Each bike slot can carry up to 55 lbs.

  • We recommend removing ebike batteries where possible and typically 4 ebikes will be at full rack capacity. Rubber bands (or bike tubes cut in ~1 inch sections) should also be placed on the brakes levers so brakes are engaged to decrease any natural motion between bike and rack.

  • Swing Aways and other hitch adaptors should be used with brake levers engaged to reduce motion between bike and rack. We now sell a hitch extender with built in anti-rattle. Check it out on the shop page. 

  • Overall height of all racks is 58 inches from the bottom of the hitch bar to the top of the tire hoops.

Vehicle Fit

SUVs -

Work wonderfully with VelociRAX! Your back door will open and clear the rack entirely.

Minivans -

Work great with VelociRAX! Your back door will open and clear the rack entirely. In rare cases (where the hitch receiver is mounted deep under the vehicle) the rear hatch door will touch bike tires when fully opened but you will have plenty of back door access with bikes fully loaded. We have minivan owners running with every rack we sell. While a fully loaded 7 rack with gear and riders will have your minivan weight capacity maxed out, it's your choice to load it up. Even with the greater ground clearance than a tray style 4 rack you may want to choose to cross deep dips in the road at an angle due to the lower clearance of some minivans. As a reference, even with a 1247mm wheelbase XL 29er (a very big bike) the back tire sits about 2 inches above the hitch bars so tapping tires is never a worry as the rack protects the bikes.

Trucks -

When the rack is hinged back to loading position, truck tailgates can open anywhere from 80-95% with bikes loaded. The dampers used in assisted hinging are easily disengaged, so the rack can go all the way to the ground when the bikes are off the rack. With many trucks having higher hitch receivers, you may need to prop up the rack slightly off the ground, so the tailgate opens fully.

Spare tire on rear of vehicle -

Yes! VelociRAX will clear and mount on a vehicle with rear spare tires. The ability to hinge the rack fully may be hindered by the spare but it will mount to the vehicle. If the spare stops the hinging and the spare can be adjusted upward the rack will be able to hinge. In general, the vertical post is 13.25 inches back from the hitch pin hole. With our extender/adapter it allows for 17.25 inches of clearance from the center of your hitch pin hole.

Single full swinging rear door -

There will be limited access and will only open slightly. Lowering the rack all the way to the ground may allow the door to fully open.

What vehicle/s are you planning to carry your rack and bikes with?

Trailer and RVs -

Please confirm you have a class III two inch hitch with a capacity of 500 lbs at a minimum. (bumper hitches, extension hitches, and hitches with cantilevered sections allow too much hitch movement and are inadequate.) One item to check is if a ladder could possibly interfere with the rack. Trailers and RVs produce extreme forces on racks and bikes. Take extra care to strap tight and use rubber bands (or bike tubes cut in ~1 inch sections) placed on the brakes levers to decrease natural motion between bike and rack.

Sprinter Style Van -

Yes! In most cases rear doors will open partially with the rack hinged to loading position and allow you to easily grab helmets etc. With bikes removed and the rack moved to the ground or camping position, both doors usually open completely.

Bike Fit

Do you ride mountain bikes?

With VelociRAX you are good to go!

Do you ride ebikes?

These bikes weigh a bit more than a standard bike. Each bike slot on a VelociRAX can take up to 55lbs. We do recommend removing batteries and accessories that can easily be removed. Rubber bands (or bike tubes cut in ~1 inch sections) should also be placed on the brakes levers so brakes are engaged to decrease any natural motion between bike and rack. Each of our racks can haul up to 230 bike pounds.

Do you ride fat bikes?

With the wider tires you will need our fat tire basket to load them. You can fit one fat bike among a rack full of “normal” bikes but know that it is going to be tighter and more spacing on our 3X, 412, or 5X racks may be nice. We prefer loading a 6 rack and placing fat bikes in slot 3 and 6.

Do you ride road or gravel bikes (bikes with drop bars)?

If you want to load 5 gravel or road bikes the 5X is for you or (the 3X also has 15 inch spacing.) If you’re carrying one drop bar bike, place it in any of our racks on the far right and it won’t interfere with the other bikes. Our 5X and 3X racks feature 15 inch spacing so drop bar bikes can be loaded without interfering with the next loaded bike. The 5X is also nice as you can unload a bike that is in the middle of the rack a bit more easily than you can on our tighter spaced racks.

Do you ride cruisers?

They load fine as well. Please note that fenders will need to be removed from the front fender.

Do you ride tandem bikes?

VelociRAX 7 can haul two with a little rope to tie the weight up; it will ride just fine.

Do you ride all these types of bikes?

So do we let’s rack’em up and get riding. Typically, you load the largest (tallest head tube height) bike on the left continuing with the same sized or smaller bikes next to it, moving to the right. If bikes touch, the load order should be switched around until clearance is found between all bikes. With many different bike geometries available today, it's hard to prescribe the perfect loading method for all situations. It will take a few minutes the first time, but loading will go quick as you get the hang of it.

Want to haul a lot of bikes?

The VelociRAX 7 is great as it will hold 7 bikes but it can also hold 4 drop bar bikes by leaving every other bike slot empty. We have had customers load 6 road bikes on a 6 rack but bars were touching head tubes and some of the bars were narrow bars. Other customers will loosen and rotate the drop bars so they can load more without touching. This does require a wrench and tightening up your bars before you ride.

Tire Fit

From 700cc road bike tires to 3”+ MTB tires to 5” fat tire and rim sizes from 20” to 29” (including 26”, 27.5”) tires will fit without modification.  Fat Tires bikes baskets are available for purchase for large fat tires if needed.

20” BMX tires

Yes they are small enough that, depending on the front fork, they can come in contact with the tire hoop they are secured to. If this is of concern, we recommend purchasing some of our extra straps to place and wrap on the tire basket to add a layer of rubber between the bike and rack.

Carbon wheels

Yes load them up there are no concerns in loading carbon wheels.

20” Mountain bikes

Have tires bigger than BMX tires and typically fit great.

16” Kids bikes

Tires on smaller bikes aren’t quite big enough to reach the lower bar but many rack owners have tied the back tire down or placed it in the center of the rack and tied it to the main post.

We’d like to say all bikes will fit but there are a few situations to be aware of.

Wheel stress

The stresses wheels take are much more extreme in the riding, jumping, and cornering with riders (that can be over 200 lbs) than are seen when bikes are racked and hanging by their weight.

Other Info

Natural sway or motion?

Loading with tires full of air with the axles and shocks that are ready to move just like they are when you ride does allow some normal natural motion in your bikes while on the rack. Rubber bands (or bike tubes cut in ~1 inch sections) placed on the brakes levers can be used to decrease this natural motion between bike and rack.

Can the rack be used off road?

VelociRAX are built extra tough with high strength steel and solid straps. We know all good trails don’t start on asphalt, so we also recommend strapping bikes tight and good judgement with all your driving.

Want to keep your rack clean?

Car wash companies will tell you not to go through the drive through. We also recommend the rack be removed before you go through an automated car wash. You can wash your rack with normal car wash soap and dry it off to keep it looking great.

What is camping mode?

Camping mode is when you lower the rack all the way to the ground allowing you to position your tire in the hoop holding the bike upright while the vehicle isn’t moving.

Tune Station

Garage Fit

The garage bracket which comes with the rack allows easy use and access in the garage. In the garage you can place it tight on the left side but you’d want 12 inches on the right to give you a little space to load the bike on the far right.
