The Rock Machine eRokk B70 City is a reliable city e-bike designed for comfortable rides in urban traffic and light off-road conditions.
With a low frame, getting on and off is easy, while the upright position saves your back and provides a great view of the surroundings.
The heart of the bike is a powerful Bosch Performance Line CX Smart System motor with a torque of 85 Nm, complemented by a 625 Wh battery - allowing for a range of up to 150 km. The system can be expanded with an additional battery for longer trips.
The Shimano ESSA 1×8 drivetrain with an 11–45 tooth range is a simple and efficient aid for everyday use. Shimano hydraulic disc brakes ensure reliable braking performance under all conditions, and pedals with a large contact area contribute to increased safety and confidence while pedaling.
The bike is equipped with a rack capable of carrying up to 27 kg and wide tires with low rolling resistance and high grip, ensuring stability and comfort even on less than ideal roads. Additionally, a powerful AXA front light (30 Lux) keeps you visible even in poor visibility conditions.
The Rock Machine eRokk B70 City is the perfect choice for anyone seeking a comfortable, safe, and versatile e-bike for everyday riding.
Batteries are one of the most valuable components on an electric bike. They often make up 1/3 of the total price of an e-bike. There are several parameters that affect the range of an e-bike: type of terrain, tyre profile, rider weight, assistance used, etc. you can read more in our blog.
The advantage of Bosch batteries is a very high quality BMS (battery management system). Thanks to temperature and voltage sensors, the BMS can switch individual cells on and off to avoid a significant reduction in range and to ensure the longest possible life of the battery itself.
Bosch motors are among the best in the world of electric bikes. Motors from the German manufacturer stand out for their reliability and quality workmanship. Bosch Performance Line CX (from MY 2022, Smart System is the motor with the maximum 340% boost. It uses a larger (38t) chainring for better power transfer. This motor is very sporty, so it is mainly designed for mountain bikes. The new feature here is the possibility of adding the ConnectModule, which will offer new anti-theft features as well as a connection to the eBike Flow app.
