Bike Compatibility

Trunk-mounted bike racks work with most types of bikes. To make sure that a rack will work with your bikes, consider the following:


Number of Bikes

Bike racks are available with maximum capacities from 1 to 3 bikes

Standard Frames

Bicycle with standard frame

Trunk-mounted bike racks work best with bikes that have a large frame and a horizontal crossbar. The rack's arms will easily fit inside the frame and the horizontal crossbar will ensure that the bike rides level. Remember that your bikes should ride as level as possible, and they should have adequate ground clearance so that they won't contact the ground while you're transporting them.


Alternative Frames

Bikes that don't have standard frames - step through frames, women's bikes, children's bikes, bikes with small frames - may not fit well on a trunk-mounted bike rack. But you can usually carry these types of bikes if you remember the following:


Arm Spacing

Arm spacing varies among different brands and models of bike racks. If your bike has a small frame, consider racks that have narrow arm spacing so that the arms fit. (But remember that wider arms will provide a more stable ride for larger bikes.)

Adapter Bars

If you can't mount your bike on a trunk-mounted bike rack because its frame is too small or it lacks a horizontal crossbar, you may still be able to take your bike by using an adapter bar. An adapter bar clamps onto the seatpost and head tube of your bike and provides a support that rests on the bike rack's arms. Most adapter bars adjust in length to allow them to fit a range of bike sizes. To ensure that a specific adapter bar will work for you, measure between the seatpost and head tube of your bike and then check the dimensions of the adapter bar.





Vehicle Compatibility

Trunk-mounted bike racks work on many different kinds of vehicles. In fact, most racks adjust so they can adapt to fit different vehicles.


Vehicle Fit

Vehicles with Spoilers

Don't let a spoiler spoil your fun. A vehicle spoiler can get in the way of a bike rack, resulting in the rack's mounting straps pushing against it, which can cause damage. But some racks are designed to be mounted on vehicles that have spoilers. These racks are usually designed to clear the spoiler on a taller vehicle - like a van or SUV - or to clear the spoiler on a sedan.

Notes





Trunk-Mounted Bike Rack Features

Some racks have extra features that make them more useful and convenient. Check out some of these features, below, to help narrow down your choices of bike racks.

Construction

Most racks are made of steel. Some manufacturers make racks of injection molded plastic or nylon. These racks are light, rust resistant, and available in a variety of colors that are molded into the plastic.

Protect Your Bikes and Rack from Theft

Unsecured bikes and racks can be an easy target for thieves. If you want to leave your bikes on your rack unattended or even leave your rack on while you go riding, you might want to consider locking your rack and bikes. Cables are available to lock your bikes to your rack. And straps are available to lock your rack to your vehicle. These straps usually have a steel core to resist cutting and a puck- or tube-shaped anchor on one end. The anchor is placed inside your trunk or hatch, and when the trunk or hatch is closed, the anchor can't be pulled out.

Some racks have built-in locks, which can make locking your rack and bikes more convenient.

Anti-Sway Cradles

The motion of your vehicle accelerating, slowing, and turning can cause bikes that are mounted on a rack to rock back and forth, possibly scratching each other or your car. To help keep bikes from swaying, some racks are made with built-in anti-sway cradles. These cradles usually have extra mounting straps that grasp a downward bar of your bike to hold it securely.

Ease of Installation

Some racks are easier to adjust to your vehicle and to install than others. The following information can help point you to racks that are easier to install.


Fit Adjustment

Bike racks have to be adjustable so that they can fit the many different shapes and sizes of vehicles out there. When you install a bike rack, you must adjust it to fit your vehicle. In most cases, you have to work with the adjustments until the rack fits correctly. To make installation easier, some manufacturers design their racks with vehicle-specific settings to make it easy to fit your exact vehicle. You can adjust these racks to the correct position (just follow the manufacturer's instructions), and you'll know that you have the best fit without any guesswork.

Number of Straps

Most racks use 6 straps to hold the rack to your vehicle. Some racks, however, have only 4, which can make installation of a rack simpler and easier.

Adjustable and Folding Arms

The support arms on some racks can be adjusted. This useful feature lets you position the arms to hold bikes level. And some racks allow you to fold the arms down out of the way when you don't have bikes loaded.

Questions and Comments about this Article

Ed

the article suggests most racks can be used on such without a hitch, yet the manufacturers page will say they have no hitch for the vehicles I need. Confusing. 76511

Reply from Chris R.

I'm not quite sure what you mean. The article is showing the different trunk-mount options (which don't require a trailer hitch) for various vehicle and bike styles. Are you looking for a trailer hitch to mount to your vehicle? If so, can you tell me the make and model? 62418
