Specialized Sirrus X 3.0 Step-Through (2026)
Offering an unprecedented combination of comfort, efficiency, and nimble handling, the Sirrus X excels on pavement, dirt, and any terrain in between.
SMOOTH, COMFORTABLE, AND EFFICIENT: Sirrus X provides the smoothest ride in its class. With bigger, confidence-inspiring tires, a slightly more upright riding position, and a super intuitive one-by drivetrain.
RIDER-FIRST ENGINEERED: Like all Specialized performance bikes, the geometry of each frame is uniquely crafted. This means that for every frame, each tube size is specifically selected to achieve the optimal balance of rigidity, weight, and responsiveness to ensure that no matter what size you’re riding, you will experience the world’s best ride.
NIMBLE: Class-leading light-weight, exceptional pedaling efficiency, and steering precision merge for confident, nearly telepathic handling characteristics.
Highlights
- Even lighter than Sirrus X 2.0, and faster thanks to an added A1 alloy fork.
- Wide-range 1x drivetrain gives excellent range on any road.
- More powerful hydraulic brakes for enhanced braking power and durability in tough conditions.

We had an outstanding experience at Cyclerie! We purchased two Aventon e-bikes, and the entire process was exceptional from start to finish. The staff took the time to help us choose the perfect bikes for our needs, recommended all the right accessories, and even installed our bike rack on the car before we left.
I had a terrific experience at Cyclerie! I love the bike I bought and working with Skip was great. He told me about customizing features that are available on the bike if you use the Aventon app.
I enjoyed my buying experience at Cyclerie. Ideal location, easy to get to, easy access to trails to test ride. … Salesperson was helpful, knowledgeable and easy to work with. No pressure to buy.
