Ecobike SX 4 Electric Mountain Bike
A powerful and reliable e-bike for conquering any trail and rugged terrain.

Who is this electric bike best suited for?
The Ecobike SX 4 electric mountain bike is ideal for anyone who enjoys riding on unpaved surfaces and needs reliable grip even in challenging conditions. It performs excellently for daily rides, while also being powerful enough to tackle climbs and easier family descents. It is the right choice for cyclists looking for a versatile MTB e-bike for recreation and outdoor adventures.

Proven Bafang motor with high torque
The bike is powered by a reliable and proven Bafang motor, located in the rear hub. With a nominal power of 250W and 45 Nm of torque, it provides enough power for most climbs and dynamic riding. The maintenance-free motor helps you smoothly and efficiently reach speeds of up to 25 km/h (limited). Its rear-wheel design does not strain the chain and other drivetrain components, ensuring a longer lifespan.

Integrated battery for exceptional range
The design of the aluminum frame allows the battery to be fully integrated, protecting it from weather and damage. You can choose between two powerful Li-ion batteries: 14.5 Ah (522 Wh) with Greenway cells or 17.5 Ah (630 Wh) with LG cells. With the more powerful version, you can achieve a range of up to 140 km. The battery has a lifespan of over 700 charging cycles, and the charging time is between 7 and 9 hours.

Safety and control with hydraulic brakes
Powerful and reliable ALHONGA hydraulic disc brakes ensure safe stopping in all conditions. Combined with a quality 9-speed Shimano Alivio derailleur, the Ecobike SX 4 provides you with complete control, precise shifting, and confidence on every descent or technically demanding section of the trail.

Comfort on the trail with SunTour suspension
The SunTour XCM front suspension fork with 100 mm of travel effectively absorbs shocks and vibrations while riding on uneven terrain, ensuring a more comfortable and controlled ride. For easier climbing, you can easily lock the fork to prevent unnecessary energy loss while pedaling.

Robust design for demanding trails
The bike is built on a durable 19" aluminum frame and equipped with robust 27.5-inch wheels. Quality TRC Dryjack or Continental Race King tires in size 27.5" x 2.10/2.20 ensure excellent grip on various surfaces. The bike has a load capacity of up to 125 kg, which attests to its solid and durable construction.
