Frequently Asked Questions

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.

Yes, it can be removed. When the floating function is not needed, the internal support system can be easily taken out from the bottom of the backpack, allowing it to be used as a regular backpack.

It only adds a minimal amount of weight—approximately 140g. We also include protective pads with the accessories to help prevent scratches on your bike.

Not at all. Our product is designed based on installation clearance rather than rider height. When installing, simply ensure there is about 1.5 inches of space between the tire and the bottom of the backpack.

Yes, it is compatible with different shapes of aero seatposts. However, we recommend using our dedicated adapter for non-round seatposts. Without it, there may be a slight reduction in stability compared to round posts, but it will not affect overall riding control.

If a fixed rear light is already installed on the seatpost, there is indeed a possibility that it may be partially blocked by the bag. To address this, we have designed a dedicated webbing strap on the lower front of the bag for attaching a rear light.

We recommend using a quick-release rear light, or alternatively, keeping an additional light mounted on the bag itself to ensure visibility and safety during night riding.

Multi-Purpose Backpack
Designed with multiple compartments and well-organized storage spaces, this backpack is ideal for users who value organization. Whether for daily commuting or travel, it helps keep all your belongings neatly arranged and easy to access.

Roll-Top Backpack
Featuring a stylish roll-top design, this backpack offers a larger overall capacity, making it perfect for carrying bulkier items or longer trips. Compared to the multi-purpose version, it has fewer compartments and focuses more on flexible, open storage space.

For more details, please refer to the Key Features section.

We use a two-stage adjustable extension design, allowing flexible length adjustment to fit different saddle positions.

I used the bag for the first time as a substitute for panniers on an Erie Canal Ride from Syracuse, NY to Fultonville, NY. I chose to limit the amount I was carrying by using a hotel instead of camping. With such a minimal loadout the bag handled everything very well. I had no serious issue mounting the bike with the pack on the back. I'm 62, male, 205 lbs and 5' 10' and not as flexible as I should/could be and still had no issues.

I do have two questions about the bag, though. There is a wire structure in the bag but the upper part of that structure doesn't appear to be attached to anything. Is it supposed to be inserted into something to create rigidity? Also, and I know for a fact this is my fault, the extra seat post strap seems to have disappeared. If it is possible to get a replacement, I'll pay for it. I'm sure I'm responsible for misplacing it.

Wow, that sounds like an amazing journey! We’re so happy to hear that our product was able to accompany you on such a memorable ride. It’s truly our honor!

Regarding the two questions you mentioned:

First, yes, the backpack does come with a metal support structure inside. It is designed to keep the front of the backpack more structured and upright, giving it a better shape and appearance.

Second, about the extra seat post strap that you mentioned is missing — no worries! We’d be happy to provide you with a replacement. We’ll send you a private message with the details and arrange it for you.

Thank you again for sharing your experience and for your support of EasiCyco!

Bag is great. I 3d printed my own mount for a 13cm aero seat post which uses the supplied screws in addition to an opening to add a double sided Velcro for enhanced attachment. I didn't want to spend for the other mount in case it incompatible. There should be an option for standard vs custom mounting bracket at checkout.

Wow, your design looks amazing! We really appreciate this special design you created for EasiCyco!

Based on your unique idea and your support for EasiCyco, we’d love to provide you with one of our custom seat post adapter accessories completely free of charge. There will be no cost to you.

Although your 3D-printed solution is very creative, we would still recommend using our official accessory, as it has been thoroughly tested to provide better safety, stability, and long-term reliability.

We hope this accessory will bring you an even better riding experience. Thank you again for sharing your creative idea with us!

The Floating Backpack is undoubtedly a product of incredible innovation. I was also highly impressed with the shipping; despite being dispatched from South Korea, the product arrived in less than two weeks.
Even on a 2020 Scott Addict RC 20 Disc model, it could be mounted without any issues using a universal irregular seatpost(aero seatpost) accessory.
However, it feels as though the product still has some room for refinement.
Here are a few specific areas that could use improvement:
Saddle Compatibility Issues: The aluminum fixing rings are not compatible with the carbon rails of the Specialized 3D-printed saddle, which is highly popular among cyclists. While the backpack remains perfectly functional without using the fixing rings, it does leave the product feeling somewhat incomplete.
Loose Telescopic Support Rod: When not actively in use, the telescopic support rod does not lock into place and moves around easily. To be fair, this isn't an issue at all once the backpack is zipped up and fully assembled for use, but it's worth noting.
Minor Cosmetic Defects (QC): The aluminum clamp connector arrived with some minor cosmetic damage right out of the box. While this superficial blemish has absolutely no impact on the backpack's actual performance, it does suggest that the brand's Quality Control (QC) standards might not be the highest.

Thank you very much for your detailed feedback and valuable suggestions. We truly appreciate you taking the time to share your experience with us.

We will definitely take your comments into account for future improvements. In our 2.0 version, we will work on enhancing saddle rail compatibility to ensure it supports a wider range of seatpost and saddle systems. We will also improve the clamp design and surface treatment to prevent any scratches during production and use, ensuring a better overall aesthetic and finishing quality.

Your feedback is extremely helpful for us to refine the product, and we will continue working to make the EasiCyco experience even better.

I bought this bag for my commute to work (30kms each way). I have a slammed Cervelo S5 and carrying a backpack is not comfortable as it gets sweaty and heavy. The EasiCyco backpack works so well, and I fill it quite full. I also bought the adapter because I have an aero seat post. There was a bit of trial and error to get the right fit to keep everything stable, but once that was sorted it is so solid, even over rail track crossings. I also like that the mounting bracket is minimal when I’m riding without the backpack. The only thing I wish you made is an insert to go in the bracket so I can mount my Garmin Varia on when I don’t have the backpack, as currently I’d have to remove the backpack bracket to use it because I don’t have enough room on the seat post.

I’ve tried many cycling backpacks, and this EasiCyco is my favorite by far. I rode over 20 km with this bag on the weekend, and the floating design is fantastic. It locks firmly to the bike so I carry no weight on my back at all, super comfy the whole way. It looks like normal size yet surprisingly roomy, I put tons of stuff in it like clothes, bottles, power bank, snacks...but felt nothing at all when riding, so so happy to have this backpack!

EasiCyco's floating backpack is simply amazing. I love it. I no longer need to cycle to work wearing a backpack. The floating backpack allows me to protect my back and use the bike I enjoy most for my commute. I highly recommend this floating backpack.

This was exactly as I expected.
With all due respect, I think it would be much better to mention in advance that if there isn’t enough clearance between the saddle and this bag, it might be uncomfortable when getting on or off the bike.

Works as advertised. Great bag! Future redesigns might want to include a convenient small pocket for phone, wallet, and keys.

The Connector from the Backpack to the Seat needs to be longer.

I cycle to work every day, enjoy a mid- length weekend ride, and have done a bit of touring, so thought this was a worthwhile investment as I don't really like classic panniers.

Pros:
- bag itself is good quality, good number of pockets/compartments, very spacious, seems sturdy enough. Mounting parts are easily removable so can be used as a regular backpack if needed

- sits directly behind you, so no uneven weight distribution or anything that's much wider than you are

Cons:
- the bag does press up against your backside if there is anything in it. I don't mind this too much for a short commute, but can see it getting annoying in the heat or over longer distances

- the connecting post is just too short. If I had my seat any further back it wouldn't be usable at all. Appreciate it can't be too long or it risks too much leverage or wobbling all over the place, but I'd like to be able to adjust my saddle without the connector becoming useless

- the rings designed to hold the clip straps in place on the seat rails would only work if your rails are a very specific size and shape. They aren't 100% functionally necessary, but if they were this would be really annoying

The most annoying part:
- doesn't clip in anywhere near as easily as it looks/says. You have to push the post into the slot to exactly the right position and it doesn't lock automatically. You have to push the clip down so if it's not in the right place you can't immediately tell and it has fallen off a few times. Not sure if mine arrived broken but if not this seems like a massive design flaw.

Can be tricky to get out for the same reason, you have to get the distance/angle exactly right or it doesn't really work and it gets stuck.

For what it costs I would really expect it to work more smoothly than this, it has been quite frustrating at times.

Hi,

Thank you very much for your honest and detailed feedback! Your comments are extremely valuable to us and will help us continue improving and upgrading the product. At the same time, we’re sincerely sorry for the inconvenience and frustration this has caused you.

Regarding the issues you mentioned:

1. The backpack pressing against your backside
We understand this can be uncomfortable, especially on longer rides or in warm weather. We’re currently considering developing a saddle-mounted accessory that would push the upper part of the backpack slightly away from your body, which we hope to launch next year.

2. The support rod being too short
We can provide you with a longer support rod. EasiCyco 2.0 will also include improvements to this part for better adjustability.

3. The rings on the saddle rails
We already have a new design that removes these rings while ensuring the buckle stays securely in place without sliding up and down. We expect to launch this together with EasiCyco 2.0.

4. Difficulty inserting the support rod
There may occasionally be a slight manufacturing deviation in the button position, which can prevent the rod from locking properly. We’ve confirmed that this can happen with a very small number of units, and we’re truly sorry if yours is one of them. We’d be happy to provide you with a new clamp and support rod as a replacement.

It may also be more difficult to insert when the backpack is fully loaded, as the shorter rod requires a more precise angle.

5. Difficulty removing the support rod
When removing it, please push the support rod fully toward the seatpost first. This gives the button enough space to be pressed down and makes removal much easier.

Once again, thank you for your honest feedback. It’s genuinely helpful to us as we continue improving the product. Please let us know if you’d like us to send you a replacement clamp and a longer support rod.

Installation was simple. Not sure I will have enough room however, once I add weight into the backpack since it barely clears over an inch without rubbing my rear tire.

Hi Diego, thanks for your feedback! We'll keep in mind the space concern and hope the backpack works well for your needs. Feel free to reach out if you need any assistance.Hi!

If you’re concerned about the clearance between the backpack and your rear tire, we currently have a new accessory that can increase the installation angle, allowing the backpack to sit farther away from the rear tire.

That said, based on your current setup, it should be completely fine to use as it is. However, if you’re still concerned, we’d be more than happy to send you this accessory for free to give you some extra clearance.

Also, our EasiCyco 2.0 is currently in development, and it will solve this issue even better without needing this additional accessory.

We hope this solution can help and give you a better experience with EasiCyco!

Product seems great so far. Is well made, was reasonably easy to setup and is a good size.
My only concern is I commute in Lycra and I am having a bit of contact with the bag which could rub and wear the Lycra.

The overall design works well - I used it on a 585 mile ride from Buffalo to NYC on the Empire State Trail. What would help is to increase the length of the primary support post; when the bag is full, it's difficult to install into the seat post bracket.

Hi! We’re glad to hear that the overall design worked well for you, especially that you completed such an impressive 585-mile ride with it!

May we ask if you’ve extended the support post to the second level? Our support post has two extension levels. If you’ve already fully extended it to the second level and it’s still not long enough, we can provide you with an extension support bar for free.

Also, our EasiCyco 2.0 is currently in development, and it will solve this issue much better. It’s expected to be released around October, so please stay tuned!

Hi, fitted my floating Backpack and everything is great. The problem is my Cycle has front and rear suspension. As soon as I sit on my Saddle the Backpack touches my rear wheel. I have fitted it to the max height fitting near my Saddle but still touching the rear wheel. I will have to fit it to my second Cycle which has no rear suspension system. Shame as I wanted it for my first Cycle.

Hi, thank you very much for supporting EasiCyco!

Yes, if the available space on the seat post is limited, using EasiCyco on a bike with a rear suspension system may cause the backpack to come into contact with the rear wheel, especially when the suspension compresses after sitting on the saddle.

If you install it on your second bike without rear suspension, it should work perfectly.

For EasiCyco 2.0, we have improved the support bar design with a much larger tilt angle. This means even on bikes with suspension systems and limited installation space, the backpack will have more clearance and avoid rubbing against the rear wheel.

When EasiCyco 2.0 is available, we’d also be happy to offer you an exclusive discount as a thank you for your support and feedback.

Great bag, I was afraid since my searpost is carbon but it works fine. I do not put too much weight in the bag to avoid risks for the post but all in all I really enjoy riding with it. No more back pain !!

Love this product! Had a small defect on one of the bars that slides out and hooks to the seat post. Company sent out a replacement. This is my second backpack from them.

Great idea but makes bicycle unstable it wobbles from side to side even with all the attachments connected to it.

Thank you very much for your feedback. Real user experiences are very valuable to us.

Some movement is normal because our backpack uses a combination of rigid and flexible connections. The fabric material also allows slight movement of the items inside. This is more noticeable when pushing or shaking the bike, but during normal riding, the impact on handling is much smaller.

We have tested different loads and compared it with traditional rear bags, and many riders found that the suspended design provides a better riding experience. You can also check our Sea Otter Classic interview video on our social media.

Of course, every rider and bike setup is different. We’re sorry if this caused any inconvenience. We recommend trying it with different loads and road conditions, then sharing your experience with us. We’ll do our best to help. 🙏
