The Upgraded X Ambition—Built for More

The latest X Ambition features Microshift Sword shifters for a sleeker cockpit, smoother shifting, and a stronger lever pull. Compressionless housing enhances braking power, giving you more control on every ride. Same incredible value, now with even better performance.

The X Ambition is designed for more—more miles, more adventures, more unforgettable moments. With a comfortable, upright riding position, an all-new saddle design, and upgraded brakes, it delivers confidence and control. The 700 x 40 Kenda Happy Medium tires balance speed on pavement with grip on gravel, so you can ride wherever ambition takes you.

Simple and Unbelievable!

Simply amazing. This bike really just begs for you to explore. The riding is butter, the turning is extremely nimble, and the possibilities nearly endless. The drop bar X’s design is extremely comfortable , the shifting is amazing, and the speed is CRAZY! Once you really get going you absolutely don’t want to stop. Riding this isn’t a workout, it’s an experience like floating on clouds. And the build quality is just the greatest; absolutely NO corners cut, half-jobs, overlooks, NOTHING! The Poseidon crew really put their love and passion into this bike and it shines so bright it might even blind you. The Dropbar X Ambition is a strong welcome for new and old riders looking to dominate or cruise their environment. My only critique is that I can’t rate this bike 10/10 stars! Amazing work!

this much fun should be illegal

I'm no mechanic - actually don't know if my tires are tubeless or how to change one if needed - but the out of box setup was easy and quick. with over 2,000 miles of snow, slush, sand, and slick pavement, to rutted roads, rocky singletrack, and banger gravel, this little adventure seeker may just make a rider out of me
