COTOUXKER Bike Rear Rack — Adjustable Seat-Post Cargo Rack 32mm Quick-Release Aluminium

COTOUXKER Bike Rear Rack is an adjustable, seat-post-mounted cargo rack with a quick-release clamp and included tie straps for secure everyday hauling.

This lightweight aluminum alloy rear rack converts most bicycles into practical cargo haulers without drilling or permanent changes. Its extendable platform and dual-support construction let you balance load and comfort, while the quick-release clamp and included wrench make installation and removal fast. Designed to fit seat posts up to 32 mm, the rack is compatible with mountain, hybrid, road, folding bikes and many e-bikes.

How does the adjustable platform improve ride balance?

The extendable platform lets you tailor the length and angle of the cargo area so weight sits closer to the bike’s center of gravity. That reduces rear-heavy feel and helps maintain steering responsiveness when carrying groceries, a backpack, or small panniers.

• Adjust length to move cargo forward or back for better balance
• Set platform angle to keep loads level over bumps
• Dual supporting arms minimize wobble under variable weight

How quickly can I install or remove this rack?

The rack mounts to the seat post with a quick-release clamp—no frame drilling required. The included mini wrench tightens the clamp securely; removal takes seconds for storage or when you don’t need extra cargo capacity.

• Seat-post mounted bracket fits ≤32 mm diameters
• Quick-release clamp for tool-assisted fast on/off
• Mini wrench included for secure tightening

Will it hold up under daily use and varied road conditions?

Constructed from high-strength aluminum alloy with a corrosion-resistant finish, the rack is built to resist rust and stay lightweight. Reinforced mounting points and dual supports add rigidity so the rack remains stable on uneven surfaces and during frequent use.

• Aluminum alloy construction for durability and low weight
• Reinforced joints reduce flex and rattling over bumps
• Corrosion-resistant coating for outdoor longevity

What accessories come with the rack and what bikes does it fit?

COTOUXKER includes tie-down straps and a small installation wrench so you can start carrying cargo immediately. The rack fits most bike types that use a round seat post under 32 mm—mountain, road, hybrid, folding, and many e-bikes.

• Tie straps secure irregular loads and bungee-friendly anchors
• Mini wrench for clamp tightening and simple adjustments
• Compatible with most seat-post-mounted systems under 32 mm

Who is this for? Cyclists who need a fast, non-invasive way to add cargo capacity will appreciate this rack—commuters, errand riders, light tourers, and anyone who wants a removable, adjustable platform to carry bags, boxes, or groceries. If you want a sturdy, lightweight rear rack that installs without frame modifications and includes straps and tools, the COTOUXKER adjustable bike rear rack is a practical choice.
