The world’s only quick-release cycling backpack that mounts to your bike without a rear rack.
It shifts the load from your back to your bike while riding — and detaches instantly when you’re off.
Instantly Switch Between Two Modes
Non-round seatposts (such as aero seatposts) require additional functional accessories
Dual-rail saddle+Sufficient installation space
No, this backpack uses a unique Penta-lock five-point system. Once installed, it’s completely secure even on bumpy roads at high speed. For most daily use, the three-point lock is already stable enough.
No, this backpack is designed for stability. It stays securely on the bike, hugs the rider’s body, aligns with the center of gravity, and is barely noticeable while riding. Even fully loaded, it doesn’t affect stability, ensuring safe riding.
The backpack’s standard maximum load is 15 kg, suitable for daily use. In static extreme tests, it has successfully supported over 80 kg.
Yes, the backpack uses water-repellent fabric with an IPX5 rating and comes with a dedicated rain cover for extra protection. We are also developing a fully waterproof version for extreme conditions.
Installation only needs to be done once and takes about 10–20 minutes. A user guide and toolkit are included, so no additional tools are required.
Mounting the backpack on the bike takes about 10 seconds, and removing it takes less than 10 seconds. It’s quick, easy, and effortless.
Yes, it is compatible, but our dedicated non-round seatpost accessory is required and sold separately. It is compatible with most non-round seatposts. Please refer to the non-round seatpost accessory product page for details.
When using the EasiCyco backpack, since it occupies space behind the saddle, we recommend the front-straddle method for easy mounting and dismounting. You can refer to the tutorial for guidance.
The backpack has a dedicated laptop compartment measuring 39×27×1.5 cm, fitting standard 16-inch laptops. The compartment also features thick padding and scratch-resistant velvet lining.
1. Yes, it is compatible with carbon seatposts. Please ensure that the tightening torque does not exceed 4 Nm when installing seatpost-mounted accessories. When used as intended and within the recommended load limits, it is designed to operate safely with carbon seatposts.
Compared to a regular backpack, this is just way more comfortable for cycling.
No pressure on the shoulders, and I don’t arrive with a soaked shirt anymore.
If you commute by bike often, this makes total sense.
The main benefit is definitely not having to wear it while riding.
It feels stable on the bike and doesn’t rattle or move around much. I was a bit skeptical at first, but it works well.
Would be nice if the mounting system was explained a bit more clearly, but overall no major issues.
Great quality and design. Love that I don’t have to wear the backpack while riding. Worth buying.
Really like the idea of switching between bike-mounted and backpack mode.
During rides, it stays on the bike, and when I stop, I can just carry it with me—very convenient.
I’d like to see maybe a bit more internal organization, but overall it works great.
I used to hate riding with a backpack because my back would get sweaty within 10 minutes.
With this, I just mount it on the bike and problem solved. It makes a huge difference, especially in warmer weather.
Honestly, I wouldn’t go back to a regular backpack for commuting.
