Riding Experience
Off-Road Riding
On a sunny weekend, my son Eric and I set out on an adventure. Eric rode his WOOM 4 bike, leading the way, while I followed on another bike. We embarked on an exciting off-road journey, determined to explore the wonders of nature and relish the joy of cycling.
Eric felt the comfort of the seat and the firm grip of the handlebars on his WOOM 4 bike. The bike’s gears allowed him to effortlessly tackle uphill and downhill challenges. The brakes responded promptly, ensuring stability and control as he maneuvered through rough trails, with beautiful natural scenery unfolding before him.
I rode on the other bike, closely following Eric. I watched him confidently navigate the trails, knowing that the WOOM 4 bike was reliable and safe. Hnoestly, I had no worries about Eric’s ride. When facing uphill sections, Eric smoothly adjusted the gear system on his WOOM 4 bike, making climbing a breeze. I also adjusted the bike’s gears, choosing the right gear to keep up. Together, we conquered steep hills, passing nature’s tests with unity and understanding between father and son.
Moving On
On downhill stretches, Eric adjusted his speed, feeling the exhilarating rush of wind against his cheeks. I gripped the handlebars tightly, steering agilely to keep up with Eric. The WOOM 4 bike’s brakes were responsive, allowing Eric to confidently control his downhill speed, while I easily applied the brakes to follow suit.
During our ride, we not only savored the excitement of speed but also relished the beauty and serenity of nature. Eric occasionally looked back to check if I was keeping up, and I responded with a bright smile, urging him to explore uncharted paths ahead. The design of the WOOM 4’s saddle and wheels provided Eric with a comfortable and stable riding experience.
Finally, we reached our destination, a lakeside meadow. Here, we parked our bikes for a picnic. After our meal, we rode back home together, and I could sense our bond growing even stronger.

Other Versions
After numerous tests, we have gained a deeper understanding of this bike. It is a highly versatile youth bike.
However, many riders have specific requirements for its performance and components. So, we conducted further research with bikes of similar type.
Woom 4 (Microshift)
The Woom 4 (Microshift) weighs 17.0 lbs and features an aluminum frame, aluminum fork, and 20″ aluminum wheels. The regular Woom 4 shares the same configuration but is slightly heavier at 17.9 lbs. The primary difference between these two bikes lies in the components. The Woom 4 (Microshift) uses microshift components, while the regular Woom 4 uses SRAM components.
Furthermore, the distinction between these two component sets is that SRAM employs an 8-speed drivetrain, whereas Microshift uses a 7-speed drivetrain. However, the overall gear range remains the same, making Microshift the lighter option.

WOOM 4 vs. Merida MATTS J. 20 Disc
The Merida MATTS J. 20 Disc weighs 20.9 lbs and is a hardtail bike. It features 40mm of front travel, providing good suspension for added comfort during rides. Additionally, this bike is equipped with hydraulic disc brakes, offering excellent braking performance, although maintenance and repairs might not be very convenient. The bike also comes with a 1×7 drivetrain, which provides decent but not exceptional shifting capabilities.
On the other hand, the WOOM 4 weighs only 17.9 lbs, lacks a suspension system, and uses rim brakes. It’s worth noting that rim brakes tend to accumulate excess heat during prolonged downhill rides, potentially causing damage to both the brakes and wheel rims. However, the WOOM 4 features a 1×8 drivetrain. Compared to the 1×7 drivetrain on the Merida MATTS J. 20 Disc, the 1×8 drivetrain offers smoother shifting and a broader range of gear options.
WOOM 4 vs. CUBE ACID 200 ALLROAD
The CUBE ACID 200 ALLROAD weighs 23.6 lbs, while the WOOM 4 is incredibly lightweight at only 17.9 lbs. This weight difference may be attributed to the CUBE ACID 200 ALLROAD having a steel fork, whereas the WOOM 4 features an aluminum fork. Aluminum forks are cost-effective, rust-resistant, and easy to repair if damaged. However, they can be brittle at welded joints and prone to fractures. On the other hand, steel forks are heavier, rigid, and offer better shock absorption. Their downside is susceptibility to rust, and maintenance might not be as straightforward.
Both of these bikes come with 20″ aluminum wheels and are equipped with rim brakes. However, the CUBE ACID 200 ALLROAD features a 1×7 drivetrain, while the WOOM 4 is equipped with a 1×8 drivetrain. The 1×8 drivetrain offers a broader range of gear options, smoother shifting, and quicker adaptation to the right gear for complex road conditions compared to the 1×7 drivetrain.
WOOM 4 vs. HOY Bonaly 20 Inch Wheel Kids Lightweight Bike
The HOY Bonaly 20 Inch Wheel Kids Lightweight Bike is priced at $483 and features an aluminum frame constructed from three sets of aluminum alloys. It boasts a lightweight design and maintains high strength where needed. Additionally, it comes with 20-inch wheels. However, its drivetrain is limited to a 1×6 system. With 6 gears and a 32-tooth chainring designed for kids, the crankset is shorter than that of adult bikes, making the riding position more suitable for children.
On the other hand, the WOOM 4 is slightly more expensive, priced at $499. It is equipped with an aluminum frame, aluminum fork, and aluminum wheels. However, its rim brakes offer only average performance and are not suitable for extended braking periods. Nevertheless, it features a 1×8 drivetrain, providing smooth and efficient shifting.

WOOM 4 vs. Cannondale Kids Cujo 20
The Cannondale Kids Cujo 20 comes with a 1×7 drivetrain, which offers decent performance. It features an all-aluminum structure, making it lightweight, but it’s priced slightly higher at $534. The Cannondale Kids Cujo 20 is equipped with mechanical disc brakes, which are convenient for maintenance. While their braking performance may not match hydraulic disc brakes, they are better than the rim brakes on the WOOM 4 in terms of safety.
On the other hand, the WOOM 4 offers a more affordable price with decent value, but its rim brakes may not be as safe. However, it features a 1×8 drivetrain. Compared to the 1×7 drivetrain of the Cannondale Kids Cujo 20, the 1×8 drivetrain offers a wider range and smoother shifting.
