Riding Experience


For me, this is a very suitable commuter bike, with comfortable geometry and high-quality road bike ride qualities. The lightweight aluminum alloy frame makes me feel very agile. My commuting route is not flat, but it still handles very well. Compared to traditional road bikes, it has wider tires, which gives me more confidence on bumpy roads. The frame is neither flat nor cylindrical, with a flat top that provides aerodynamic effects and a smooth bottom that adds cushioning and rigidity. This can reduce weight without sacrificing strength.

On those very bumpy roads, I choose to open its front suspension, and the up-and-down handlebars make me feel very comfortable. The 63mm suspension is perfect for urban bumps, making driving smoother and easier to accelerate on flat surfaces. The bike I tested has a full black color on the frame, with red lines as decoration. The mudguard at the bottom of the down tube is very distinctive, integrating the cable and blocking mud and water from splashing onto the front wheel.

The mixed Shimano kit on this bike does not feel out of place. The 3-speed front Tourney and 8-speed rear Acera are perfect for complex urban roads, with smooth gear shifting.

Weekend Exercise

It’s also great for weekend bike rides and even off-road adventures on mountain trails! The Roam 3 Disc’s versatile gearing allows me to easily traverse steep inclines and speed along roads. The braking power of the Tektro TKB172 mechanical disc brakes, with a rotor diameter of 160mm, is provided by a well-balanced system that can efficiently brake even at high speeds, ensuring complete safety.

The low-rise handlebars are very long and slightly angled upward, similar to those on a mountain bike. This means that you can have a comfortable, open-chested riding position, which allows for better control of your bike in traffic. The Giant Crosscut has become a popular tire brand, leaving a deep impression during my test ride.

The 700×38c tires are a good combination of hybrid and mountain bike tires. The stylish and sturdy tread combines with a durable outer casing to ensure that the tires are safe when making quick turns and rolling quickly on rough roads. The puncture-resistant tires provide additional protection against small punctures.

The more upright seating position also makes my ride more comfortable. Similar to those on road bike saddles, the saddle is smooth and wide, with a perfect shape. It also fits my sit bones very well and has enough padding to cushion my pain.

Overall, this hybrid bike has a very comfortable riding position and a sturdy lightweight alloy frame. The front suspension with a lockout can perfectly release its performance when needed, allowing for smoother and faster riding even on bumpy roads. The Tektro mechanical disc brakes are powerful enough to operate well in both dry and wet conditions. Undoubtedly, it is the ideal choice for anyone who wants to buy a hybrid bike for fitness, commuting, or occasional travel.


The Giant Roam Disc 3 is an excellent value hybrid bike with high-performance components and a range of excellent features. Its appearance is beautiful, and it performs outstandingly, making us very satisfied.

Firstly, it is equipped with a set of Giant double-wall aluminum rims. These rims use 30mm wide hubs, making the bike ride more comfortable. Its braking performance is also excellent, providing a safer riding experience for riders. In addition, the frame itself is equipped with a Shimano Tourney drivetrain system, allowing users to adjust speeds under different road conditions, making riding more enjoyable. It is also equipped with a set of Tektro TKD-143 disc brakes. These disc brakes have excellent performance and can provide good braking even under harsh road conditions. Its handlebars are also made of high-quality materials, providing a more comfortable riding experience for riders.

In conclusion, the Giant Roam Disc 3 is an excellent value hybrid bike. It is equipped with a range of high-performance components and excellent features, making it popular among similar bikes. Its riding performance is outstanding, and it is also very durable, allowing riders to enjoy a safe and comfortable riding experience under different road conditions.
