Trunk racks ($30–150) strap to your car using hooks and straps — no hitch or roof rack required. They work on most sedans and hatchbacks. The tradeoffs: they contact your car paint (use pads), have lower weight limits (usually 2 bikes at 35 lbs each), and can shift in transit if not secured correctly. Good for occasional use; replace with a hitch rack if you carry bikes weekly.
Hitch racks mount to a 1.25-inch or 2-inch trailer hitch receiver — the most secure, most convenient, and most popular rack type. Hanging hitch racks ($100–300) dangle bikes by the top tube. Platform hitch racks ($400–800) hold bikes by the wheels — no frame contact, easier loading, works with non-standard frames. The Kuat NV 2.0, Thule T2 Pro, and RockyMounts BackStage are top-tier options.
Roof racks keep bikes completely clear of your car's rear, allow trunk access, and look integrated. The downsides: loading and unloading bikes overhead is physically demanding (especially for heavy e-bikes), you can't use drive-throughs or parking garages, and they create wind noise and fuel economy penalties at highway speeds. Best for vehicles with existing roof rails and when garage clearance is not an issue.
Hanging racks are less expensive and work with standard diamond frames. Platform racks (like the Kuat NV) hold bikes from underneath by the tires — no top tube contact means they work with carbon bikes, full-suspension mountain bikes, and frames that lack a flat top tube. The loading experience on a platform rack is also easier — no lifting over the top tube.
Locking cable locks and locking hitch pins prevent rack and bike theft when you stop at a trailhead. All premium hitch racks include a locking hitch pin for the receiver. Additional cable locks through bike frames and the rack's integrated cable are standard practice at any trailhead where you'll be out of sight of the car.
Yes — trunk racks require no hitch and work on most cars. Roof racks require factory roof rails or naked roof crossbars (most cars can have these added for $200–400). If you plan to carry bikes regularly and your car can be fitted with a hitch ($200–500 installed), adding a hitch and getting a proper hitch rack is worth the investment.
Standard hitch racks hold 2 bikes. Extender kits add capacity to 4 bikes (with a 2-inch receiver). Maximum bike counts on roof and trunk racks vary by brand — most trunk racks top out at 3 bikes. Weight capacity matters more than bike count for e-bikes, which can weigh 50–70 lbs each.
