What is a double bicycle bag?

A double bicycle bag is a set of two bags that are connected and hang over the luggage rack of your bike. Because there are two, you have double the storage space compared to a single bicycle bag. 

This makes them ideal for transporting larger amounts of items, such as groceries or camping gear. Double bicycle bags come in various styles and materials, allowing you to choose what best fits your cycling needs. So it doesn't matter if you're a city cyclist or going on long bike rides. 
 

What size double bicycle bag should I have?

The right size of a double bicycle bag depends on how much luggage you typically carry. Large bags, with a capacity of 40 liters or more, are suitable for people who do a lot of grocery shopping or travel long distances. For daily use in the city, a smaller double bicycle bag of about 30 liters is often sufficient. 

It’s also important to check if the bag fits on your luggage rack, both in terms of width and attachment. And don’t think that with this type of bag you can carry double the weight on your bike. That depends on the load capacity of your bike's luggage rack. The right size double bicycle bag really depends on your specific needs and type of use. Here are some guidelines to help you make the right choice:
 

1. Daily use (work/school/daily items):

•    Capacity: 30-40 liters.
•    Why: This is sufficient for daily items such as a laptop, lunch, books, or a jacket. It strikes a good balance between capacity and compactness.
•    Example: If you bike to work or school and don’t do large grocery shopping, this size is ideal. You often think of this type of bag as a shoulder bag (messenger bag), which you can click onto your luggage rack. 
 

2. Groceries or larger loads:

•    Capacity: 40-60 liters.
•    Why: If you frequently use the bicycle bag to transport larger loads such as sports equipment or extra clothing, then a larger bag with a capacity of 40 to 60 liters is ideal. This size gives you enough space to carry multiple grocery bags or larger items without needing to make multiple trips.
 

3. Bike vacations or long trips:

•    Capacity: 50 liters.
•    Why: For bike vacations or long distances, you need more space for items such as clothing, camping gear, or food. A larger capacity ensures you can take everything you need for longer rides without compromising on space.
 

4. Compact or light use:

•    Capacity: 20-30 liters.
•    Why: For short rides or light use such as a quick errand or a visit to the gym, a smaller double bicycle bag is sufficient. These are lighter and more compact, making them easy to handle.
 

Other considerations:

•    Width of the luggage rack: Ensure that the bicycle bags fit well on your luggage rack. Some wide bags may restrict legroom while cycling.
•    Water resistance: Opt for waterproof or water-repellent bags if you often cycle in the rain.
•    Design and comfort: If you also value style, there are many options with beautiful designs that are both practical and fashionable. In our range, you will find a wide variety of designs. The designs of the double bicycle bags will appeal to women, men, and children alike. 

With these guidelines, you can choose the right size based on how much and what you want to transport daily. And if you want to combine a child seat with a double bicycle bag, that is possible. You can use the Steco Tas-Mee luggage rack extender for that.
 

How do I attach a double bicycle bag to my bike?

There are several ways to mount a double bicycle bag on your luggage rack, depending on the type of bag and your bike. Here are the most common attachment methods:
 

1. Straps or Velcro

Many double bicycle bags are attached with straps or Velcro. These straps are threaded through the spokes of your luggage rack and tightened, ensuring the bag stays securely in place. This is a simple and versatile method that fits most bikes.
 

2. Hooks

Some double bicycle bags use hooks to hang the bags on the luggage rack. These hooks click onto the sides of the luggage rack, providing a stable attachment. This system is convenient if you want to quickly remove and reattach the bags.
 

3. Click or adapter systems

There are also double bicycle bags that use special click systems or adapters, such as the MIK system with the Basil MIK adapter plate or KLICKfix with their luggage rack adapter. These systems make it easy to click the bags onto the luggage rack and quickly detach them when needed. This is especially handy for e-bikes, as these systems are often compatible with wider luggage racks and batteries.
 

4. Mounting plate

Some bags have a mounting plate that is laid over the luggage rack and secured with straps or screws. This provides extra stability and prevents the bags from shifting while cycling. This system is often used for larger or heavier double bicycle bags.
 

5. Integrated attachment

In some bicycle bags, the attachment is integrated into the design, where the bag is directly attached to the luggage rack via fixed loops or eyes. This method is usually permanent and less suitable for bags you want to remove regularly.
When mounting your double bicycle bag, it’s important to ensure that the bags are securely fastened and do not come into contact with the wheels. Also, make sure that the bags do not disrupt the balance of your bike.
 

What are the advantages and disadvantages of a double bicycle bag?

A double bicycle bag offers many advantages. They have a large storage capacity, are convenient for heavy loads, and distribute the weight evenly across your bike, which increases stability. Moreover, you don’t have to constantly ride with a backpack, which is more comfortable. 
A disadvantage is that double bicycle bags take up more space on your bike. This can be challenging if you often need to park your bike in tight spaces or maneuver through narrow passages. You also need to consider the weight you carry, as overly heavy loads can make the bike less maneuverable.
 

Are all double bicycle bags waterproof?

Is a double bicycle bag waterproof? Not all double bicycle bags are waterproof. Many models are splash-proof. This means they can withstand light rain, but your items may get wet in heavy downpours. If you often cycle in all weather conditions, opt for waterproof double bicycle bags made from PVC or other water-repellent materials. 

For extra protection, some bags also come with removable rain covers. This type of bicycle bag is ideal for people who want to keep their items dry during rainy rides. If you want to make your double bicycle bags waterproof, you can use a rain cover. By doing this, you add an extra layer of protection against rain and make your bicycle bags doubly waterproof, at least in some cases. 
 

Is every double bicycle bag suitable for an e-bike?

Not every double bicycle bag is directly suitable for an e-bike, especially if the bike has a battery under the luggage rack. When choosing a bicycle bag for an e-bike, consider the following factors:
 

1. Width of the luggage rack

E-bikes often have wider luggage racks. Many standard bicycle bags do not fit well here, as they may be too narrow or leave insufficient space between the bags. Special e-bike bags are wider and provide a better fit.
 

2. Battery under the luggage rack

A battery under the luggage rack can limit the space for standard bags. E-bike specific bags have cutouts or a modified design to fit around the battery without obstructing the attachment.
 

3. Attachment system

E-bike bags often have sturdier attachment systems, such as hooks or click systems, which ensure stability at higher speeds or on bumpy roads.
 

4. Weight and load capacity

E-bike bags are generally more robust and can carry heavier loads, but pay attention to the maximum load capacity of your luggage rack to maintain the balance of the bike.
 

5. Customized models for e-bikes

Special bicycle bags for e-bikes are designed to provide space for the battery and ensure stable attachment, often with extra reflectivity for safety at higher speeds.
In short, it is important to choose bicycle bags that are specifically designed for the wider rack and the battery when using an e-bike.
