Ouxi and the H9

The Chinese brand Ouxi (a subsidiary of Shenzhen HTOMT Technology Co., Ltd.) has been making a name for itself since 2019 with its innovative and affordable electric bikes. Initially known for its hoverboards and scooters, the brand has now carved out a prominent place for itself in the European cycling scene.

While the famous Ouxi V8 is best known as the quintessential rugged and versatile fatbike, the H9 positions itself as its sportier, higher-end big brother. The H9 retains the brand’s recognizable cruiser look but features a more aggressive frame geometry and more advanced components, designed with riding comfort and safety in mind.

Technical Specifications Put to the Test

Engine and Speed

The motor is the beating heart of an electric bike. The H9 is equipped with a 250-watt brushless motor. This power output is required by law to use the bike in Europe and Belgium as a pedal-assist electric bike. The motor provides a maximum assisted speed of 25 km/h.

Right from the start, even in the lowest assist mode, you can immediately feel the motor responding smoothly. Since the assist cuts off at 25 km/h, the bike remains perfectly balanced on a busy bike path. Accelerating from a stop at a red light is effortless thanks to the motor’s torque, allowing you to keep up with traffic with ease.

Battery and autonomy

The bike is powered by a removable 48 V, 15 Ah battery. The Ah (ampere-hour) indicates the battery's capacity. This capacity, combined with that of the motor, determines the distance you can travel. According to the specifications, this provides a range of 60 to 80 kilometers, depending on the selected assist mode, the rider’s weight, and weather conditions.

During a mixed-use test—both in the city and on gently rolling country roads—we achieved a realistic range of about 65 kilometers in medium-assistance mode. The big advantage of the removable battery is that it can easily be taken to the office or home to be recharged, which saves a lot of hassle.

Suspension and tires

One of the H9's strengths is its suspension system. The bike is equipped with both a front suspension fork and a dedicated rear suspension (under the seat). This combination is complemented by tires famous 20-inch tires typical of fat bikes.

It’s out on the trail that the bike truly reveals its potential. The tires absorb small vibrations, while the dual suspension effortlessly handles larger bumps, such as potholes or tree roots on a forest trail. Where traditional city bikes with tires become uncomfortable on cobblestones, the Ouxi H9 lets you literally glide over bumps. This makes the bike particularly well-suited for long rides as well as off-road trails.

Brakes and Safety

The Ouxi H9 is equipped with dual hydraulic disc brakes. Hydraulic systems use brake fluid rather than a metal cable. When the brake lever is squeezed, pressure is transmitted directly and evenly to the brake discs.

In practice, these hydraulic brakes perform exceptionally well and inspire great confidence. They respond instantly and require little hand force. Even during an emergency stop at 25 km/h, the bike comes to a quick and controlled stop. These brakes maintain excellent grip, even in wet conditions, which significantly enhances safety on the road.

Speeds and Display

To make riding more enjoyable at different speeds, the H9 is equipped with a 7-speed Shimano derailleur. The bike also features a clear digital display that serves as an on-board computer.

Shimano gears shift smoothly and precisely. Combined with the 250-watt motor, they allow you to find the right pedaling cadence at any time, even when riding into the wind. The display remains easy to read even in direct sunlight and accurately shows your speed, battery level, and the active assist mode.

Smart Tips

Modern fatbikes come with an increasingly comprehensive set of features. The H9 not only has a clear display but also innovative features such as a built-in alarm and, depending on the model, an NFC chip for keyless locking. Powerful LED lights with built-in turn signals are also often included on the latest models.

The built-in alarm and NFC chip provide great peace of mind when parking your bike. The lights are bright enough to keep you clearly visible in the dark, and the built-in turn signals help you communicate more clearly with other road users.

But what truly sets the H9 apart from its competitors is its exceptional riding comfort. Thanks to the dual suspension and tires , road bumps are perfectly absorbed.
