Total weight of all bicycle components - engine, battery, frame and accessories. EcoBike electric bicycles have the lowest weight-power ratio

250 W

Engine power

The power of the electric bicycle's engine translates into the maximum speed to which the engine will assist your ride. Some EcoBike electric bikes have the option of choosing engine power, which allows you to support up to 25, 35 or 45 km / h - depending on the country's traffic regulations

We have redefined a technology that has been proven in all conditions for years. Meet the Ecobike SX300. An e-bike MTB that combines the continuation of fantastic performance with the design of the future.
The Ecobike SX300 is characterized by a unique design. The new frame design makes the e-bike immediately eye-catching, but it also works perfectly in practice. The battery is an integral part of the frame, completely lost in it, and the geometry ensures great comfort, good weight distribution and safety.

Electric system is based on the technology with a central motor by DAPU®, proven and appreciated for years by users of our bikes, which generates as much as 90 Nm of torque. It helps to overcome even difficult slopes without any problems and riding it is a pleasure.
The system is powered by LG battery. You can configure your bike with batteries of capacities of 10.4 Ah or 14 Ah 48V. The Smart BMS technology we use ensures the effective operation of the battery and contributes to its longer life.
The system is supported by a control panel with a colour display. It has been equipped with a dusk sensor that automatically adjusts the screen backlight to the conditions in which you are moving. Its friendly interface ensures intuitive navigation between individual functions and settings.
The motor and battery have been placed carefully to maintain the best possible weight distribution.

At Ecobike, we use good components from proven suppliers.
We've achieved superb traction by using Impac® SMARTPAC TwinSkin 29 x 2.10 tires and an excellent shock absorbing RST® Blaze TNL front fork.
An e-bike with a powerful motor requires a solid derailleur - in this case we chose a Shimano® ALIVIO with 9 gears.
In difficult conditions, the brakes are the basis of safety. The SX300 uses Shimano® hydraulic disc brakes.

Ecobike SX300 will allow you to discover not only beautiful places, but above all new possibilities!
