Your e-mountain bike probably weighs 55 to 75 pounds and has tires up to 5 inches wide. That makes most car racks useless. You need a rack that holds 60 to 80 pounds per tray, fits fat tires, and locks onto a 2-inch hitch without wobbling. This guide covers three racks that actually work.

You drive a pickup, an SUV, or an RV. You need a rack that won’t sag under a heavy e-mountain bike. After checking the specs and owner feedback, here is the full breakdown of the bike rack for e mountain bikes that actually fits the category’s demands.
Our Picks at a Glance
How To Choose The Best Bike Rack For E Mountain Bikes
E-mountain bikes weigh about 50 to 80 pounds, have tires up to 5 inches wide, and wheelbases that can stretch beyond 50 inches. A standard rack designed for a 30-pound road bike will fail. Here are the three specs that separate a solid rack from a risky one.
Weight Capacity Per Tray
The single most important number. Your e-mountain bike likely weighs around 55 to 70 pounds. Look for a rack that carries at least 60 pounds per tray. The Hollywood Racks models here handle 80 pounds each, which gives you a solid margin so the rack doesn’t flex on bumps or steep grades.
Tire Width and Wheelbase Compatibility
Fat-tire e-bikes use tires up to 5 inches wide. Check that the rack’s wheel channels or trays can accept that width. Also measure your bike’s wheelbase — the distance between the front and rear axle. Many racks cap out at 48 to 50 inches, so if your e-mountain bike is longer than that, the rack may not clamp both wheels properly.
Hitch Class and Installation
All three racks here use a 2-inch receiver. Some require a class 3 or higher hitch because of the extra weight. If you drive a smaller SUV or a crossover with a 1.25-inch receiver, you need an adapter or a different rack. The Hollywood RV Rider even states it requires a minimum class 3 trailer hitch.

In‑Depth Reviews
1. Hollywood Racks Sport Rider 2″ Hitch Bike Rack
Our pick — over 4.5★ from 900+ verified ratings; the strongest balance of quality and price.
The heavy-duty workhorse that swallows two 80-pound e-mountain bikes without a complaint.
This rack lives up to its “Sport Rider” name at 56 pounds, making it a sturdy anchor. It carries two bikes weighing up to 80 pounds each, which is the highest per-tray limit you will find at this price tier. It holds 80 pounds per tray versus the KUAT Transfer V2’s 60 pounds per tray — a meaningful gap if you own a burly e-MTB that tips the scales near 70 pounds.
Buyers report that the wobble-free hitch-tightening system keeps the rack steady on long highway drives, and the wheel holders accommodate tires up to 5 inches wide, so fat-tire bikes fit without modification. The rack also folds flat against the car or truck when not in use, and it tilts down so you can open your rear hatch even when two e-bikes are loaded. The locking frame clamps and included locking hitch pin and security cable provide real theft deterrence.
The catch is the weight: at 56 pounds, it is not light to lift on and off a hitch alone. Also, the manufacturer states this rack should not be used with any hitch extension longer than 8 inches, and it is not recommended for travel trailers or towed vehicles.
What owners love
- 80 lbs per tray — handles even the heaviest e-mountain bikes
- Accepts tires up to 5 inches wide for fat-tire bikes
- Locking frame clamps and cable for added security
- Tilts down for vehicle access with bikes loaded
A few trade-offs
- Weighs 56 lbs, so lifting it alone is tough
- Not designed for RV or travel trailer use
Reach for this if: You own two heavy e-mountain bikes (up to 80 lbs each) with fat tires and want a wobble-free, lockable rack for daily use on a truck or SUV.
Look elsewhere if: You need a lighter rack for frequent on-off mounting, or you plan to attach it to an RV or towed vehicle.
2. KUAT Transfer V2 2″ 2-Bike Hitch Bike Rack
The lean, steel runner that trades 20 pounds of capacity for 4 pounds less total baggage.
KUAT designed this rack for drivers who prioritize a lower installed weight without sacrificing steel durability. At 52 pounds, it is lighter than the Hollywood Sport Rider at 56 pounds, which makes it easier to handle during installation. It supports up to 60 pounds per tray, which covers most e-mountain bikes under 60 pounds, and handles wheelbases up to 50 inches and tires as large as 5 inches with an accessory strap.
A standout feature is the tamper-resistant hitch security and a semi-integrated bicycle cable lock — owners mention this gives confidence when parking at trailheads. The arms grab the tires instead of the frame, so the bike’s paint stays untouched. However, the 60-pound per tray limit means it is not suitable for the heaviest e-bikes that push past 65 pounds. The rack is also built with a dedicated 2-inch hitch, and it can be mounted on campers or trailers with chassis-mounted receivers.
Owners mention the FlatLock hitch cam keeps the rack tight to the vehicle with no wobble at highway speeds, and the 52-pound weight is noticeably easier to lift on and off than the 56-pound Hollywood racks. The trade-off is a lower capacity per tray at 60 pounds versus the Hollywood Sport Rider’s 80 pounds, so check your bike’s weight before purchasing.
Best for lighter e-MTBs: If your e-mountain bike is under 60 pounds and you value a lighter, easier-to-install rack that still uses heavy-duty steel, the KUAT Transfer V2 is the better fit. The weight difference of 52 pounds vs the Hollywood Sport Rider’s 56 pounds makes a real difference during mounting.
One realistic limitation: Riders with e-bikes over 60 pounds should choose the Hollywood Sport Rider instead for extra capacity margin.
Pick this if: Your e-mountain bike weighs under 60 pounds and you want a lighter steel rack with integrated cable lock and no-frame-contact tire arms for aesthetic protection.
Skip this if: Your e-bike is 65 pounds or heavier — you need the 80-pound per tray capacity of the Hollywood Sport Rider.
3. Hollywood RV Rider Hitch Bike Rack for 2 E-Bikes
The overbuilt hauler for RV travelers who need 160 pounds of total cargo strength.
This rack is purpose-built for RVs, fifth wheels, and flat-towed vehicles. It carries two e-bikes up to 80 pounds each for a total of 160 pounds. It is the same 56-pound rack weight as the Hollywood Sport Rider, but with a beefier receiver tube designed to handle the vibration and stress of RV towing. The dimensions are 39 x 20 x 9 inches — giving more space between the two trays so heavy bikes don’t touch.
Security features include heavy-duty wheel holders, a locking security cable, and frame grabbers that hold each bike in place. The rack folds up neatly when not in use, and it tilts down for rear cargo access even with bikes mounted. It requires a minimum class 3 trailer hitch with a 2-inch receiver. Customers note the hitch tightener keeps everything steady on rough roads, and the construction feels solid even with two heavy e-bikes loaded.
The main limitation is compatibility: it is not designed for standard car hitches or 1.25-inch receivers, and at 56 pounds it is the heaviest rack in this comparison. Also, the manufacturer states it cannot be used on travel trailers or towed vehicles — only on the RV motorhome itself, fifth wheel, or flat-towed vehicle.
RV-specific advantages
- 160 lbs total capacity for two heavy e-bikes
- Heavy-duty receiver tube for RV use
- Larger platform (39 x 20 x 9 inches) prevents bike contact
- Tilts down for rear access with bikes loaded
Before you buy
- Requires a class 3 or higher hitch (not for smaller vehicles)
- Weighs 56 lbs — not a lightweight option
Perfect for: RV owners who need to carry two heavy e-mountain bikes (up to 80 lbs each) on their motorhome or flat-towed vehicle, and want a dedicated RV-rated rack with extra tray space.
Not ideal for: SUV or pickup drivers who don’t have a class 3 hitch — the Hollywood Sport Rider is a better fit for standard vehicles.
Understanding the Specs
Weight Capacity Per Tray
This is the maximum weight the rack can hold on each individual bike tray. E-mountain bikes typically weigh 50 to 80 pounds, so a rack that handles at least 80 pounds per tray gives you a safety margin. The Hollywood Racks models carry 80 pounds per tray, while the KUAT Transfer V2 carries 60 pounds per tray. Always check your bike’s actual weight before buying.
Tire Width and Wheelbase Limits
E-mountain bikes often have tires 4 to 5 inches wide. Your rack must accommodate that width in its wheel channels. Also measure the distance between your bike’s axles — the wheelbase. The KUAT Transfer V2 handles wheelbases up to 50 inches, while the Hollywood racks fit tires up to 5 inches wide. If your bike exceeds either number, the rack won’t secure both wheels properly.
Hitch Class and Receiver Size
A 2-inch receiver is standard for heavy-duty racks. Some racks also require a class 3 or class 4 hitch due to the weight they carry. The Hollywood RV Rider specifically requires a minimum class 3 trailer hitch. If your vehicle has a 1.25-inch receiver, you will likely need an adapter or a rack designed for that size.
Security Features
Look for integrated cable locks, locking hitch pins, and frame clamps. The Hollywood racks include a locking hitch pin and security cable. The KUAT Transfer V2 adds a tamper-resistant hitch security and a semi-integrated cable lock. These features matter when you leave your e-bikes unattended at trailheads or campsites.
