Ebike Attachment: Top Ebike Trailer Options For Cargo And Kids
You've unlocked a new level of freedom with your e-bike. Now you're wondering how to expand its utility even further. The most common question we hear is: can you attach a trailer to an e-bike? The answer is yes. But it's not always a simple plug-and-play situation, and there are several important factors you need to consider before making your purchase.
The key is understanding compatibility between your bike and the trailer. An ebike attachment like a trailer can transform your ride into a family-friendly vehicle or a serious cargo hauler. This guide will walk you through everything you need to know. We'll cover the critical connection points, safety considerations for towing, how performance is affected, and our expert recommendations for the best cargo and kid trailers on the market.
Our goal is to give you the confidence to choose and use an ebike trailer attachment safely and effectively.
Understanding E-bike Trailer Connections
Before you can haul anything, you need a secure connection between your bike and trailer. The most common ebike trailer attachment method is the axle-mounted hitch, which is a small metal plate with a hole that fits over your e-bike's rear axle. This provides a coupling point for the trailer's tow arm. While simple in concept, the primary challenge is compatibility, especially with different e-bike designs that vary significantly from traditional bicycles.
The biggest hurdle is the rear hub motor that many e-bikes use. Many e-bikes use a motor built into the rear wheel hub, which can physically interfere with a standard hitch plate. The wiring for the motor often exits through the axle, leaving no room for the hitch. In these cases, you will likely need a specialized nut or adapter designed to extend past the wiring and provide a secure mounting point for your trailer connection.
Understanding your axle type is equally important for successful installation:
Quick-Release Skewers are the traditional standard on non-electric bikes. A hitch can usually be fitted easily by replacing the skewer with a slightly longer one provided with the trailer. Solid Axles or Nutted Axles are common on e-bikes with hub motors, and the hitch plate slides onto the axle before the outer nut is tightened. This is where you might need a special adapter to clear motor wiring. Thru-Axles are the modern standard on higher-performance electric bikes, including many with mid-drive motors, and these require a specific thru-axle adapter that replaces your stock axle.
As noted in Consumer Reports' guide on bike trailers, ensuring your equipment is compatible is the first step toward safety.
E-bike Drivetrain vs. Trailer Hitch Compatibility
| Drivetrain Type | Standard Axle Hitch | Specialized Adapter Needed |
|---|---|---|
| Mid-Drive Motor | Usually compatible (may need thru-axle adapter) | Rarely |
| Rear Hub Motor | Often incompatible due to wiring/hub size | Frequently |
Towing: Performance and Safety
Towing a trailer fundamentally changes how your e-bike behaves. The added weight and length require you to adjust your riding style, but the power of an e-bike makes the experience far more manageable than with a traditional bike. You need to be aware of several key performance changes that occur when you add a trailer to your setup.
Braking is the most critical safety consideration when using any ebike attachment. The total weight of you, your bike, your trailer, and your cargo can easily double, which significantly increases your stopping distance. Fortunately, most e-bikes are equipped with superior hydraulic disc brakes that provide the necessary power to manage this extra mass. Always test your brakes in a safe area after attaching a loaded trailer to get a feel for the new stopping distance.
Handling and cornering also require significant adjustment when towing. You must take turns much wider than usual to prevent the trailer's inside wheel from clipping a curb or obstacle. Avoid sharp, sudden swerves at all costs. Smooth, deliberate movements are key to maintaining stability and preventing dangerous situations.
Your e-bike's battery range will decrease when towing due to the increased power demands. The motor has to work harder to pull the extra weight, especially when accelerating from stops or climbing hills. To maximize your range, use a lower level of pedal assist whenever possible, accelerate smoothly from a stop, and ensure the tires on both your e-bike and trailer are inflated to the recommended pressure.
The Physics of E-bike Towing: A Quick Primer
Why exactly does towing drain your battery faster? It comes down to two main factors: increased total system weight and increased rolling resistance. Your motor must overcome the inertia of a much heavier setup to get moving and maintain speed. Furthermore, the trailer's extra wheels add rolling resistance, which is the force required to keep the tires rolling over a surface. These combined forces demand more power from the motor, thus consuming more battery life per mile.
Pre-Ride Safety Checklist
Check that the hitch connection is secure and the locking pin is in place. Verify the safety strap is properly looped around the bike frame and back to the tow arm. Test your brakes to ensure they feel strong and responsive. Check tire pressure on both the e-bike and the trailer. Ensure cargo is secured and the weight is balanced low and centered over the trailer's axle.
Top Cargo Trailer Options
An ebike attachment for cargo can replace a car for grocery runs, hardware store trips, or even bikepacking adventures. The right trailer depends on your primary use, budget, and the type of terrain you plan to cover. Different designs offer distinct advantages for different situations.
For Everyday Errands: The Versatile Two-Wheeler
For tasks like hauling groceries or moving bulky items, a two-wheel trailer like the Leoguar Bike Cargo Trailer is an excellent choice. Its design provides a wide, stable platform that is easy to load and unload without worrying about balance. A key advantage is its stability when parked; you can load multiple heavy bags without worrying about your bike and trailer tipping over, which is a common issue with single-wheel designs. The Burley Flatbed offers a substantial carrying capacity and a large footprint for oversized items.
Weight Capacity: 132 lbs /60 kg
Cargo Area Dimensions: 51.18″ x 23.62″ x 19.69″
For Adventure & Off-Road: The Nimble Single-Wheeler
If your goal is to take your gear onto singletrack trails or uneven terrain, a single-wheel trailer like the Burley Coho XC is the superior choice. Its narrow profile allows it to track perfectly behind your e-bike, leaning with you into turns and navigating tight spaces where a two-wheel trailer would struggle. This makes it ideal for bikepacking and off-road touring where maneuverability is crucial. The trade-off is that it requires more care when loading and must be balanced, as it cannot stand on its own.
Weight Capacity: 70 lbs / 31.8 kg
Cargo Area Dimensions: 31.5" x 16" x 11.5"
Top Kid Trailer Options
When using an ebike attachment to carry children, safety is the absolute, non-negotiable priority. The power of an e-bike makes pulling the extra weight effortless, allowing you to focus completely on smooth and defensive riding. However, this also means you need to be extra careful about speed control and sudden movements.
Reputable child trailers are rigorously tested to meet safety standards like the ASTM F1975-15 safety standard. This covers everything from the structural integrity of the frame and wheels to the harness system and the absence of sharp points. Never purchase a used or off-brand trailer that doesn't explicitly state compliance with these standards, as your child's safety depends on proven engineering and quality construction.
While premium trailers like the Burley D’Lite X remain a popular choice, the Leoguar Bike Child Trailer offers a practical, budget-friendly alternative for e-bike families. It features a strong steel frame, weather-resistant fabric, a secure 5-point harness, and a stable anti-tip hitch. With space for 1–2 kids and stroller conversion, it's ideal for casual rides and weekend outings.

When riding with children, your focus should be on providing the smoothest ride possible. Avoid sudden braking or acceleration, and call out bumps before you go over them. Following safe riding practices with children in tow ensures that every journey is enjoyable for both you and your precious cargo.
A Practical Installation Guide
Attaching the trailer hitch to your e-bike is usually a straightforward process that takes only a few minutes. However, it's important to follow the steps carefully to ensure a secure connection that won't fail during use.
First, identify your rear axle type: quick-release, solid nut, or thru-axle. Remove the skewer or axle nut from the non-drive side, which is the side without the chain and gears. Place the trailer's hitch plate onto the exposed axle, ensuring it sits flat against the bike's frame. Securely reinstall the skewer or nut, tightening it to the manufacturer's specification - if you have a thru-axle, you will replace the entire axle with the trailer-compatible version. Connect the trailer's tow arm to the hitch and insert the locking pin. Finally, loop the nylon safety strap around your bike's chainstay for redundant security in case the main connection fails.
