What Is a Bag Cylinder?

A bag cylinder is a tubular waterproof roll bag designed for bicycles and e-bikes. It attaches securely to the rear rack or seat, providing a storage solution with a 20-60L capacity. The roll-top closure keeps your gear dry, while the sturdy straps or bungees prevent the bag from shifting during rides, even on bumpy terrain. For A-Spadz riders, these bags fit seamlessly with e-bike models like the QREATE City Air, providing added space for essentials without straining your back.

Constructed from durable materials like PVC or canvas, bag cylinders often feature reflective accents for improved visibility, which is especially beneficial for night riding. These bags are designed to be compact and easy to use, fitting snugly on racks without interfering with the battery or wheels.

Bag cylinders are ideal for a variety of activities, including commuting, touring, and weekend adventures. Riders can use them to carry clothes, tools, snacks, and more, enhancing the practicality of their A-Spadz e-bikes.

What Are the Benefits of Bag Cylinders?

Bag cylinders offer numerous benefits for e-bike riders, including waterproof storage, even weight distribution, and easy access to gear. They provide a quick, strap-on solution that reduces back strain compared to backpacks, which is particularly useful for long commutes or rides. With reflective panels, these bags also enhance visibility, making them safer to use during low-light conditions.

These bags excel in wet weather, offering reliable protection against rain with their multi-roll closures. On A-Spadz models like the City Pro, bag cylinders maintain stability, helping balance the bike even when fully loaded. Their versatility also allows them to be converted into backpacks, offering flexibility when you’re off the bike.

In terms of longevity, bag cylinders are made from heavy-duty materials that ensure durability through many seasons of use. They are also affordable, with options for customization like adding lights or GPS pouches.

How to Choose the Best Bag Cylinder?

To choose the best bag cylinder for your A-Spadz e-bike, consider factors like capacity, waterproof rating, and mount type. You should select a bag that matches your rack and load needs. Prioritize roll closures and secure straps to ensure the bag stays in place, even on rough rides. A budget of $40-$100 is typical for quality options.

The dimensions of the bag also matter—most racks can accommodate bags around 50x30cm without causing wheel rub. For A-Spadz models like the CAVET Air, a 40L capacity is ideal, as it avoids interference with the 20" tires. Material is also important: PVC offers durability, but make sure the bag's weight limit is compatible with your bike's specifications.

E-bike models like the A-Spadz QREATE may have additional considerations, such as ensuring the bag does not interfere with the motor or battery.

How to Install a Bag Cylinder on an E-Bike?

To install a bag cylinder on your A-Spadz e-bike, first secure it by threading the included straps or bungees through the loops on the rear rack or seat. Roll the top of the bag 3-4 times to seal it and tighten the straps for a secure fit. This process typically takes less than 2 minutes.

Make sure the bag is positioned centrally over the axle to maintain balance, especially on models like the QREATE City Pro. Thread the straps through the frame’s eyelets or the rack bars, but avoid the chain or motor area. After installation, test the setup at low speeds to ensure the bag doesn’t sway.

For A-Spadz models like the CAVET Air, the alloy rack may require additional padding, especially if you're carrying a heavier load.

Are Bag Cylinders Waterproof?

Yes, bag cylinders are fully waterproof when the top is rolled 3-4 times and securely sealed. The bags are made with seam-sealed PVC and have a no-zip design to prevent water from entering. These features make them a great option for A-Spadz e-bike riders who frequently commute in rainy weather.

The construction of the bag, including double-rolled tops and welded seams, ensures that your gear stays dry even during heavy downpours. However, it’s important not to overfill the bag, as this could compromise the seal. Packing the bag loosely will help maintain its waterproof capabilities.

What Size Bag Cylinder Is Best for E-Bikes?

When choosing the right size bag cylinder for your e-bike, consider your intended use. A 30-40L bag cylinder is ideal for daily commutes, while a 50-60L option is better suited for longer tours. Be sure to match the size to your bike's rack and tire clearance to avoid interference.

For A-Spadz models like the QREATE, a 40L bag fits perfectly without rubbing against the 27.5" tires. Smaller bags are great for daily use, while larger ones can accommodate gear for longer trips.

Can Bag Cylinders Fit A-Spadz E-Bikes?

To ensure a perfect fit, make sure your bag cylinder is at least 30cm away from the tires. No modifications are necessary, and the bags complement the lightweight, durable racks found on A-Spadz models.

Why Use a Bag Cylinder Over Panniers?

Bag cylinders are simpler to use and provide more centered balance compared to panniers. They attach quickly with straps, and their roll-top closure ensures waterproofing, unlike panniers that rely on side hooks and zippers. A-Spadz e-bike riders prefer bag cylinders for their stability and ease of installation.

Additionally, bag cylinders are often convertible to backpacks, which is an added benefit when you’re off the bike. For quick trips or errands, bag cylinders are more practical than panniers.

Conclusion
