Momentum UX 3S 
Momentum UX 3S 

The UX series has always been one of Momentum’s most popular lineups, but is it just because of its lower price or does it truly offer value for the money? What changes can it bring to mundane city commuting? With these questions in mind, I immediately placed an order for a Momentum UX 3S and hoped to answer them through firsthand experience.

In the following analysis, we will delve into the riding experience, key features, components, specifications, and other versions of the Momentum UX 3S. Additionally, in the latter part of this article, we will compare it to several top bicycle models. If you’re interested in more bike reviews, feel free to follow us.

Riding Experience

City Commuting

As the morning sun bathed the city and vehicles and pedestrians started to fill the streets, I hopped on the Momentum UX 3S to go to work. Why is it so quiet? This question suddenly popped into my mind. After riding for a while, I realized it was the charm of the UX 3S belt drive system, as there was almost no noise during the ride.

Furthermore, the relaxed geometry allowed me to ride in an upright position, which was particularly friendly for someone like me with lower back fatigue. The Selle Royal VIVO Ergo saddle, with its uniquely designed wing guard, helped alleviate pressure on the sit bones, further enhancing comfort. I swiftly maneuvered through the flowing city traffic, breathing in the fresh air and feeling the wind on my face. It seemed like I was witnessing a different scenery than before.

When I saw the green light at the intersection starting to countdown from a distance, I pedaled harder with tightened legs. To be honest, the distance was quite far, and I was merely testing my luck. The Momentum UX 3S’s 2.1-inch wide CST 1899 tires provided decent speed, but unfortunately, I couldn’t catch up to the time. Luckily, the Tektro M275 Mechanical Disc braking system allowed me to stop in time, ensuring my safety.


It had been six months since I last saw my friend, Petter. During our Thursday evening call, he decided to come over for a weekend, and he quickly booked his round-trip flight on Skyscanner.

On Saturday, we planned to go for a bike ride in the outskirts, and I brought along the Momentum UX 3S. The bike’s appearance, handlebars, seat post, and other designs always gave me the feeling of a hardtail mountain bike. This time, it proved to handle some undulating small hills quite well. The Shimano Nexus Inter3 shifter was more responsive than some grip shifters I had used before, and the three-speed internal gears allowed me to confidently tackle changing terrains. However, I did find it somewhat challenging on steeper uphill sections. But hey, how much can we expect from a city commuting bike?

Throughout the ride, the Momentum UX 3S’s ALUXX-Grade aluminum front fork and Alloy riser bar provided good support, allowing me to easily control the bike and maintain stability. Even on bumpy surfaces, the double-wall 6061 aluminum rims provided peace of mind.

In conclusion, I believe the Momentum UX 3S is a comfortable commuter bike that can meet the recreational riding needs of most people.


When I first laid eyes on the Momentum UX 3S, I was pleasantly surprised.

The ALUXX-Grade Aluminum frame gives the bike a clean and sleek appearance, while the blue and white aluminum front fork undoubtedly adds to its premium look and feel.

Moreover, the belt drive design, although uncommon due to cost reasons, not only offers a silent ride but also requires minimal maintenance.

Unlike a chain, the belt doesn’t need lubrication, so it won’t attract dust and dirt, remaining clean and tidy.

However, perhaps to control the price, the UX 3S is only equipped with a basic 3-speed internal gear system, which can be a bit challenging when encountering more complex road conditions.

Next, the 2.1-inch wide CST 1899 tires reduce the sense of heaviness during the ride and provide decent speed performance.

When you’re running late for work, the Momentum UX 3S will be a reliable companion.

From a geometry perspective, the 73° seat tube angle allows riders to maintain stability on uphill sections. This not only enhances comfort but also makes pedaling easier.


Other Versions

The Momentum UX 3S is a comfortable hybrid bike. However, if you have a limited budget, we also have recommendations for other models.

Momentum UX 9S

Momentum UX 9S

The Momentum UX 9S adopts the traditional chain drive, which, although not as quiet and clean as the belt drive of the Momentum UX 3S, features a 9-speed gear system that offers greater functionality and better adaptability to complex terrains.

One notable aspect is that the Momentum UX 9S has stronger braking capability. The Tektro Hydraulic Disc brakes are more effortless and provide better braking performance compared to the UX 3S’s Mechanical Disc brakes, offering improved safety during high-speed riding.

However, the entry-level Shimano Alivio and Altus mixed components of the Momentum UX 9S are inferior to the same-brand components of the Momentum UX 3S.

If you prioritize performance, I would recommend choosing the Momentum UX 3S.

What do we like about it?

  • Belt drive that requires minimal maintenance.
  • Selle Royal VIVO Ergo saddle to alleviate sit bone pressure.
  • Shimano Nexus Inter3 grip shifter for easy adjustment.
  • ALUXX-Grade aluminum front fork for good support.
  • Durable double-wall 6061 aluminum rims.

What don’t we like about it?

  • The 3-speed gear system may struggle with complex terrains.


  • What kind of tires does the Momentum UX 3S use and what is the tire size?

It uses CST 1899 27.5×2.1″ tires, which are perfect for city riding and provide good speed performance.

  • What are the features of this bike?

The standout features of the Momentum UX 3S are the belt drive, which provides a quiet ride, and the grip shifters instead of trigger shifters.

  • How do I choose the size of this bike?

The Momentum UX 3S is friendly to most riders of all heights, with three sizes to choose from. The sizing chart below you can use as a reference, but it’s normal if it differs from your idea. Because the best way to find the best size is to try it on.

Momentum UX 3S vs Cannondale Adventure 2

Cannondale Adventure 2
Cannondale Adventure 2

First of all, what pleasantly surprised me about the Cannondale Adventure 2 is its Suntour NEX-E25 front fork with 50mm of travel.

It offers better suspension performance compared to the ALUXX-Grade Aluminum front fork of the Momentum UX 3S.

This means a more comfortable ride for your arms, especially on bumpy roads. However, the Adventure 2’s SmartForm C3 frame falls slightly behind the ALUXX-Grade aluminum frame of the Momentum UX 3S.

If you’re a petite woman, the extremely low top tube of Cannondale Adventure 2 makes it easy for you to mount and dismount.

The gentle color scheme may also appeal to you. However, the microSHIFT components might make you hesitate.

If you’re looking for better performance, the Momentum UX 3S would be a good choice.

Momentum UX 3S vs Cannondale Adventure EQ

Whether it’s the Cannondale Ergo Comfort saddle or the 300mm seatpost, they both indicate that the Cannondale Adventure EQ is designed with comfort in mind. It indeed provides a great option for commuters who need a reliable transportation tool. What impressed me is that the Adventure EQ comes equipped with foldable pedals and a stem, making it convenient for you to park in narrow spaces.

Furthermore, the self-powered Dynamo lights of the Cannondale Adventure EQ are cyclist-friendly for those who ride at night. Even in unfavorable weather conditions, the Adventure EQ’s full-coverage fenders keep you dry. However, if you have a limited budget and desire a quieter riding experience, the Momentum UX 3S with its belt drive would be more suitable.

Momentum UX 3S vs Cannondale Bad Boy 3

When I first saw the Cannondale Bad Boy 3, I was immediately drawn to its sleek matte black finish, which gives it a cool and stylish look.

The internal cable routing adds to the overall clean appearance of the bike and makes it easier to clean.

The integrated top tube bumper is a standout feature that protects the frame when leaning on the bike.

While it is a city bike, the Cannondale Bad Boy 3 with its WTB Byway 650bx40c tires can handle more complex road surfaces. The Tektro M275 hydraulic disc brakes also provide enhanced safety.

However, I feel that the Bad Boy 3 falls a bit short of Cannondale’s claim of being the “ultimate urban ride.”

The microSHIFT Mezzo components it comes with are noticeably inferior to the Shimano components of the Momentum UX 3S.

If you’re looking for a more agile ride, considering the low-trail design of the Momentum UX 3S might be worth it.

Momentum UX 3S vs Fuji Adventure 27.5 Comp ST

Fuji Adventure 27.5 Comp ST
Fuji Adventure 27.5 Comp ST

The Fuji Adventure 27.5 Comp S is a hybrid electric bike that offers great value for money.

What surprised me is that it even comes with a 60mm Zoom CH-565 front fork.

It reduces the impact on your arms when riding on steep and rugged terrain, providing a comfortable experience even during long rides.

The Shimano 3×7 speed drivetrain offers ample range to handle various complex situations. I must say, the Fuji Adventure 27.5 Comp S caught my attention.

Both bikes have distinct geometric designs. The Fuji Adventure 27.5 Comp S has a slightly shorter rear chainstay length, which enhances its maneuverability.

However, if you prioritize bike stability, the Momentum UX 3S would be more suitable. Additionally, the Fuji Adventure 27.5 Comp S has a lower stack height, which some riders may prefer to maintain a forward-leaning position for increased speed.

However, long rides in that position can be tiring, so I prefer the Momentum UX 3S, which allows for a more comfortable upright posture.


Above is our review of the Momentum UX 3S. It offers an unforgettable riding experience with its comfort. Whether for urban commuting or outdoor adventures, it delivers a satisfying performance.

In our opinion, the Momentum UX 3S is a bike worth purchasing. Considering all these factors, we gave it a high rating of 4.7. If you’re interested in trying out higher-end hybrid electric bikes, feel free to check out our other reviews.
