Can I Attach Bike Trailer To Any Bike?

As an avid cyclist and parent, I know firsthand how fun and rewarding it can be to bring your child along on bike rides in a trailer.

However, I also learned quickly that not every bike is suited for the task of pulling a trailer safely.

Mismatched bike and trailer combos can be unstable, hard to control, and even dangerous.

So what kind of bike do you need to securely attach a child bike trailer?

I spent many hours researching and testing different setups to find the ideal features.

In this detailed guide, I’ll share everything I’ve learned about bike and trailer compatibility.

I’ll cover trailer attachment steps, bike styles and components that work, speed considerations, and tips for choosing the right “trailer towing” bike for your needs.

My goal is to provide you with clear, easy-to-understand advice so you can pick out a capable bike for family adventures.

Let’s dive in!

Can I Attach A Bike Trailer To Any Bike?

The short answer is no, not every bike on the market can safely and effectively pull a trailer.

However, many standard bike styles are compatible if equipped with the right features.

In most cases, you’ll want a bike with:

  • Sturdy frame construction, preferably steel, aluminum, or carbon fiber.
  • 26-29 inch wheels with road/hybrid style tire width. Avoid fat tires.
  • Horizontal rear dropouts to provide stable trailer arm attachment.
  • Mounting points like braze-ons or eyelets for a trailer hitch or stay.
  • Mechanical disc brakes for reliable stopping power with a trailer load.

Flat handlebars also provide a more upright position for regularly looking back at the trailer.

So while not just any bike will work, many common commuter, hybrid, touring, and mountain bikes have the characteristics needed to safely manage a trailer with a child inside.

Let’s explore these key components and considerations in more detail:

Frame Material

The bike frame needs to be strong enough to handle the extra weight of a loaded trailer without flexing or compromising stability.

Steel is the classic choice preferred by many touring cyclists – it’s fatigue-resistant and absorbs shock well.

But it’s heavier.

Aluminum frames are also quite rugged and trailer-worthy.

Plus, they shed pounds for easier pulling.

Carbon fiber is strong and very light, but the rigidity requires caution with heavy loads that could crack the frame.

In general, steel and aluminum check the boxes for dependable trailer-towing durability.

Wheel Size

Standard road and mountain bike wheel sizes between 26-29 inches typically work best for trailers.

Larger diameters roll smoothly and maintain momentum. Narrower widths provide clearance.

Avoid novelty sizes like 20-24 inch or fat/plus sizes that can limit space and handling.

Wheels with road or cyclocross style widths around 28-32mm are ideal for stability under load.

Rear Dropouts

The rear dropouts need to accommodate the trailer connection arm securely.

Horizontal dropouts are ideal. They keep the arm clamped firmly in place even under load.

Vertical dropouts found on some bikes can allow the arm to slip down, causing dangerous sway.

Mounting Points

Mounts like eyelets and braze-ons provide solid attachment points for hitches and trailer stays.

Without multiple mounts, you’ll struggle to connect a trailer securely and maintain control.

Standard mounting placement is on seat stays near the rear wheel dropout.

Brakes

A trailer full of your precious cargo adds considerable weight and momentum to your bike.

Reliable, all-weather brakes are a must for slowing and stopping this inertia safely.

Disc brakes provide the best performance for frequent trailer towing.

Standard caliper or V-brakes work but require extra care, early braking, and dry conditions.

Handlebar Style

The rider position also matters when frequently glancing back to monitor a trailer.

Flat handlebars allow an upright posture ideal for shoulder checks.

Drop bars on some road bikes limit visibility making monitoring difficult.

So while not just any bike will work, many properly equipped common bike styles can pull a trailer effectively.

Can I Attach A Bike Trailer To My Road Bike?

You may be wondering specifically about attaching a trailer to a road bike.

The answer is yes, in many cases!

Road bikes are designed for efficient pedaling on pavement.

While quick and agile, their sleek geometry isn’t always ideal for trailer towing.

With that said, many standard road bikes can pull a trailer if:

  • The bike has eyelets/mounts for a trailer hitch or stay.
  • You use a lightweight, streamlined trailer without adding too much load.
  • You have strong brakes to handle the added weight.
  • You don’t ride too fast – stay below 15mph maximum.
  • You use wider tires (25-28mm) at lower pressure for stability.

The challenge is road bikes sometimes lack necessary mounting points for hitches or load capacity for heavier trailers.

Racing road bikes with ultra-skinny tires and weak brakes are also poor trailer candidates.

But a touring road bike with disc brakes and a slightly more relaxed geometry can potentially work well with a light trailer and child passenger.

Let’s look at how to assess your road bike’s capability:

Road Bike Frame

Thinner road frames may flex or wobble under the added stress of a trailer.

Stick to sturdy aluminum, steel or carbon frames.

Tire Clearance

Skinny road tires don’t provide much stability. Look for clearance to fit at least 25mm tires.

Brakes

Standard road caliper brakes lack stopping power for heavy loads. Upgrade to discs.

Geometry

Aggressive racy angles don’t mix well with trailers. Choose endurance or touring geometry.

Eyelets & Mounts

Lack of braze-ons or eyelets limits hitch mounting. See if any adapter is available from the manufacturer.

With the right specs, a road bike can make a good towing companion.

But confirm it has the needed capacity and components before hitching up.

What Kind Of Bike Do I Need For a Trailer?

To recap, here are the key features to look for in a “trailer ready” bike:

  • Steel, aluminum or carbon fiber frame for durability under load. Avoid excessive flexing.
  • 26-29 inch wheel sizes with road/hybrid tire clearance. Wider tires enhance stability.
  • Horizontal rear dropouts to keep the trailer arm clamped securely in place.
  • Multiple mounting points like eyelets or braze-ons to solidly attach a trailer hitch/stay.
  • Disc brakes for reliable all-weather stopping power with the extra weight.
  • Steady, responsive handling when loaded down. Test ride any bike first.
  • Flat or upright handlebars for regularly looking back at a towed trailer.

Based on these criteria, good trailer towing bike options include:

Touring Bikes

Purpose-built for carrying gear long distances. Very trailer friendly.

  • Steady & stable handling with load
  • Multiple eyelets & mounting points
  • Large tire clearance
  • Strong brakes

City/Commuter Bikes

Built for everyday around-town riding and small loads.

  • Durable urban frame and wheels
  • Upright comfort for visibility
  • Can support a lightweight trailer

Cyclocross Bikes

Quick and nimble like a road bike but trailer-capable.

  • Light and efficient for small loads
  • Mounts for racks & panniers
  • Medium tire width

Mountain Bikes

Rugged, stable, and feature mounting points. Focus on cross country vs. downhill.

  • Very strong frames and wheels
  • Excellent brakes
  • Wide tire clearance
  • Suspension helps smooth bumps

Hybrid/Comfort Bikes

Upright position plus ideal frame and components for trailers.

  • Flat bars for checking on trailer
  • Durable wheels and tires
  • Frame mounts for racks/hitches
  • Powerful brakes

Carefully check the specs of any individual bike model before purchase.

Not all bikes within the same category are created equal when it comes to trailer towing!

Test ride while pulling a loaded trailer if possible.

How Fast Can You Go With A Bike Trailer?

When pulling a loaded trailer, it’s important to control your speed for both stability and safety.

Most bike trailers have a recommended maximum speed of 15-20mph depending on road conditions.

Exceeding the limit can compromise handling as the extra weight pushes you faster downhill.

It also prevents proper braking.

Here are some tips for safe speeds with a trailer:

  • Pedal conservatively and avoid coasting at high speeds where braking is harder.
  • Use lower gears both for better acceleration control and to prevent exceeding the limit downhill.
  • Pull over and take breaks to walk around and stretch if you feel you’re going too fast.
  • Communicate with your child and ask them to tell you if the ride seems too bumpy or fast.
  • Choose routes with flatter terrain and bike paths or lanes separated from heavy traffic.
  • Add a handlebar-mounted rear view mirror so you can monitor both bike and trailer speed.
  • Install a trailer hand brake for extra stopping power at faster speeds.
  • Maximum 15mph on roads and bike paths. 10mph or less on bumpy, winding or gravel trails.

Staying at lower speeds may take some adjustment. But a slow and steady pace is crucial for protecting your child.

How Do You Put A Bike Trailer On A Bike?

Attaching a bike trailer isn’t difficult but takes practice to master:

  1. Confirm your bike has the necessary hitch, stay or rack mounts.
    This may require adding braze-ons, eyelets or an adapter.
  2. Prep the trailer tongue coupler or stay attachment to match your bike.
    Adjust fit and locking mechanism.
  3. Tilt trailer tongue upwards and rest coupler on mounts or stay on rear rack.
    Insert bolt or screw bar and hand tighten.
  4. Use wrench to fully tighten coupler bolt or screw clamp.
    Test for snug fit without wobble. Add locking nuts.
  5. Attach trailer arm to rear wheel dropout with specially fitted skewer.
    Ratchet tightly.
  6. Pull trailer arm towards bike, engaging spring loaded cassette.
    Test for firm attachment. Loosen arm clamp if too tight.
  7. Use straps or clips to secure trailer wheel safety lines to bike frame as failsafe backup.
    Eliminate slack.
  8. Do complete safety check of hitch, arm, and wheel connections before each ride.
    Retighten anything loose.

I recommend practicing hitching and unhitching a few times in your yard before hitting the road.

Get to know the steps and your bike’s particular nuances.

Routinely inspecting and maintaining the hitch mechanism is also critical.

Don’t take chances with your child’s safety!

Final Thought

Finding the right bike to tow a child trailer isn’t always straightforward.

But focusing on key features like durable framing, quality components, and trailer mounting options goes a long way.

While not every bike works, many common styles like touring, city, or mountain can pull a trailer when properly equipped.

I hope these tips give you confidence picking out a smooth rolling, stable “trailer tugger” bike for fun family adventures!

Just take it slow and double check those trailer attachments before every ride.
