When the road becomes unpredictable trail, there is no room for unproven solutions.
You need a bike you can rely on.
Meet the SX. An e-bike MTB that you won't hesitate to go further than the others.

The Ecobike SX looks like it has been drawn by a simple movement, but its design is the result of complex work.
The frame has been designed in such a way that, while maintaining good ergonomics, it can accommodate the entire battery.
We have obtained a durable construction that holds the battery well, and inserting and removing it has become more convenient.
As always with Ecobike, you can configure your e-bike with batteries of different capacities: 14.5 Ah, 17.5 Ah.

Our proven electric system, which we have used on our bikes since years and we constantly improve, is responsible for a unique riding experience and reliable assistance.
A powerful and maintenance-free Bafang motor that transfers power through the rear wheel will allow you to climb hills and will not give up even in difficult conditions.
With the modern controller, you will not have to worry about the drive system - it will take care of itself while you are enjoying the ride.
On the easy-to-use control panel you can read the most important parameters and choose the best settings for you.

We want to be sure that the SX will not let you down, so durable equipment is a must.
We used, among others high-quality Shimano Altus/Alivio derailleurs and hydraulic Alhonga brakes, excellent SunTour XCM fork and very strong tires TRC Dryjack.

We have created a new MTB model. Choose your favorite from among the three variants and go into unknown!

What is the difference between an e-bike and a traditional bicycle?

An electric bike, or e-bike, supports muscle strength and makes it easier to climb hills and travel over longer distances. An electric bike can be a fast and cheap means of transport in the city (electric city bikes, e.g. the Ecobike City series). There are also electric mountain bikes (MTB), trekking, which give a lot of pleasure to ride on any terrain. Ecobike electric bicycles are suitable for everyone. Skills or age don't matter.

How fast can I ride an electric bike?

Electric bicycles reach different speeds, depending on the power and type of motor, as well as the battery. The fastest of them, e.g. Ecobike speed bikes have a maximum speed of about 40 kmph. In accordance with applicable regulations, electric bicycles can travel on public roads at speeds up to 25 km / h. After exceeding this speed, the electric support is turned off and we are dependent on the strength of our muscles. In addition to public roads, you can unlock the maximum speed using the display panel

Is an electric bike heavier than a regular bike? How much does an e-bike weigh?

An average electric bike weighs about 24 kg. Additional kilograms include engine, battery and drive system. The higher weight of the bike is not felt in any way while riding.

How long does it take to charge the electric bicycle battery? Where can i do that?

The electric bicycle battery is charged anywhere that has access to a regular outlet. We can charge it at home, at work, anywhere. It is important to follow the manufacturer's rules set out in the instructions, including use the original charger and do not allow long-term discharge

How often do you need to charge the battery?

The frequency of charging depends on the driving style. Some will charge the battery every day, others every week. If we use the electric bicycle regularly, we charge the battery when it is discharged. Remember to use the original charger and not to drain the battery during extended periods of non-use (e.g. in winter), but to maintain a charge level of approx. 60-80%. Thanks to this, we will significantly extend the battery life

What is the battery life span? How long does the bike battery last?

The analysis shows that the average battery of an electric bicycle retains its original capacity after about 700-800 charging cycles (manufacturers usually indicate a value> 500 cycles). This means that with very intensive use of the electric bicycle all year round, when charging the battery every 2 days, the battery will remain functional for up to 3 years! Importantly, after this time, the battery will continue to work, but may gradually require more frequent cycles and reduced capacity

Electric bicycle and rain or snow

In what atmospheric conditions can you ride an electric bike? The answer to this question is: everybody. Electric bicycles, including their motors and batteries, are specially adapted and secured to serve throughout the year, regardless of the weather.

How to care for an electric bike? Can you fix it yourself?

An electric bicycle requires similar maintenance as a traditional bicycle. To avoid breakdowns and problems, you must regularly clean dirt, dust, mud. Ecobike electric bicycles have already traveled tens of thousands of kilometers without any fault. However, when a malfunction occurs, it is advisable to contact a professional service.
