Central motor DAPU MD250S
The MD250S excels with a high torque of up to 95Nm, thanks to which it offers a ride, with a sufficient reserve of power, even in the most difficult terrain. The compact dimensions and minimalist design of the MD250S motor allow elegant installation in the frame, which does not disturb the visual appearance of the entire e-bike.
It offers 250 W / 350 W power, an integrated well-tuned control unit and excellent efficiency (more than 80 %), thanks to which it achieves an exceptional range value on a single charge. When driving, you will appreciate not only the performance, but also the exceptionally quiet operation. Even on the steepest climbs, the DAPU motor will help in a very significant way.

Battery Sport Drive 504 Wh (14 Ah)
Fully integrated battery with the 4th generation Sport Drive system. The battery has a capacity of 504 Wh. At the same time, it's still easily removable so you can charge it separately if needed.
It is equipped with a BMS board (Battery Management System) that protects it from overheating, short-circuiting or overcharging. The battery can be charged directly in the frame of the e-bike, or it can be removed for charging. You can travel up to 100 km on a single charge (depending, of course, on the profile of the track and how the assistance is used). A fully discharged battery can be charged to full capacity in 6,5 hours.

Displej SPORT DRIVE 4 generation
The SPORT DRIVE 4th generation display is perfectly legible in all light and weather conditions. Intuitive and very easy to use.
The display is supplied with external buttons for controlling support and function changes, a switch on a 22.2 mm sleeve and a 320 mm connection cable. Electrical wiring with a 70 cm long connector. 25.4 mm handlebar mounting sleeves + 22.2 mm reducer + 2 screws for mounting sleeves. Also included is a USB cable for charging external devices with cap (smartphone, flashlight, etc...).

The same great passion that led the early enthusiasts to build the first e-bike always leads them forward - to enjoy the joy of creating the best e-bikes and bring them to others.
Months driven over every detail of the new frames, thousands of hours of tests and many miles flown, this is the life of the designers of this company, and it is precisely these feelings that the Rock Machine e-bike ride will bring you.
Rock Machine is a lifelong passion and mission, as is riding their e-bikes. Everyone loves an active lifestyle, so it's no wonder that e-bikes have been involved since 1994.
