Incredible Value – A True Do-It-All Gravel Bike!
I absolutely love my Poseidon X Gen 3! I’ve been riding it for a full year now, and it has exceeded all of my expectations.
Prior to receiving it, I assumed I would want to upgrade several components right away. However, the stock setup has performed well, and I have not yet changed a thing. It is incredibly lightweight and handles a massive variety of riding conditions beautifully. Whether I am hitting gravel/trails or cruising on pavement, it serves as the perfect universal bike.
For reference on sizing, I am 6’0” with a 33.5” inseam, and the XL frame fits me well and provides a highly comfortable ride.
As someone who is very familiar with bicycle assembly, I found the setup process to be straightforward. I was out out on the road riding within an hour of the box arriving at my doorstep. If you are looking for a versatile, budget-friendly gravel bike that punches way above its weight class, I cannot recommend the Poseidon X Gen 3 enough!

Good value, sizing needs work
The X Gen 3 is a good value; specs and price is great. After 200+ miles, I have no complaints.
I have one issue though. No issue with the bike, but the sizing listed on the site. Using the recommended sizing, I ordered the medium. However, with the bike built, it was too big. I’ve always had size 52cm bikes; the medium is listed as 51cm. I had to exchange it for a size small, 49cm, which fits perfectly. So keep that in mind when ordering.
Otherwise, the bike is very good. Would recommend once you get the sizing worked out.
Thank you.

Several issues to get going but fine now
Was really excited to get started with this bike but I've had a number of issues getting started. Bike crank falling off mid ride, after installing (and fully tightening) the pedals one also fell off and stripped the threads which I had to get fixed. Disappointed to have to deal with some of this on a brand new bike getting started but aside from that it's been a fine starter bike. Had some questions on the installation service and that took days and ~5 emails to get a response, so not super stoked on the response time either.
