Bicycle bag Topeak BackLoader 6 L Nylon Saddle Mounting

The Topeak BackLoader 6 L is a saddle-mounted bicycle bag designed for bikepackers who need a streamlined way to carry extra gear without installing a rear rack. Made from durable nylon with polyethylene reinforcement, it offers 6 litres of storage in a compact shape (approximately 500 mm wide, 160 mm deep, 150 mm high). The bag includes an inner waterproof liner to protect contents from rain and splashes.

Advantages

The BackLoader combines lightweight construction with high water resistance and durable materials, allowing it to withstand outdoor use. Its upgraded saddle mount system and compression straps minimise pendulum movement from large rear loads, and the quick-mount design makes installation and removal fast and tool-free. The included waterproof inner bag provides additional protection for sensitive items.

Suitable for

• Bikepacking and multi-day cycling trips
• Long-distance rides where rackless packing is preferred
• Transporting clothing, sleeping accessories, or spare layers
• Cyclists who need a compact, high-capacity saddle bag

When it may not be suitable

This saddle bag is not intended to replace full rear panniers when very large or heavy loads need to be carried; riders needing maximum capacity or rigid load support should use a rack and panniers. It may also be less suitable for bikes with unusual saddle rail layouts or very short seatposts where securing the mount and achieving stable clearance is difficult.

Key specifications

• Capacity: 6 litres
• Materials: nylon with polyethylene reinforcement
• Approximate dimensions: 500 mm (width) × 160 mm (depth) × 150 mm (height)
• Mounting: saddle-rail mount with upgraded stabiliser and compression straps
• Included: waterproof inner liner

How to use

Attach the BackLoader to the saddle rails using the saddle mount system and secure the stabiliser under the seatpost or seat rails as instructed. Use the compression straps to compress the load and reduce movement while riding. Place items inside the main compartment and insert the waterproof inner bag for protection against rain; roll or close the inner bag according to its closure method. Remove the bag by releasing the mount for quick access or when transferring between bikes.

What to consider before purchase

• Check saddle rail compatibility and seatpost clearance on your bike
• Confirm 6 L capacity meets your storage needs for intended rides
• Consider whether rack-based panniers are required for heavier loads

Usage recommendations

Distribute weight low and centred, pack heavier items closest to the saddle, and regularly tighten the compression straps to maintain stability during long rides. Use the waterproof inner bag for electronics and clothing to keep them dry.
