About Rock Machine

From the very beginning in 1994 to the present day, one rule has always applied here: no matter what happens, what matters is having fun in the saddle. For the 2022 season, they updated the company motto in that spirit, and it now reads: Fun first! Most employees are cyclists too, so they test newly developed prototypes in the local mountains. That’s how finely tuned bikes and e-bikes are made in Kopřivnice—always with passion and experience.

E-bike description

A modern low-step women’s 29” e-bike with a Sport Drive mid-drive motor and the new Fun Ride geometry. Thanks to that, riding the Storm is easier and more comfortable not only on roads but also off-road. In addition to the lockout suspension fork, comfort and confidence are ensured by 2.25” WTB tires with a versatile fast-rolling tread, and hydraulic disc brakes will bring you to a safe stop. The bike can be equipped with a rack, fenders, a lock, lights, and a kickstand = Touring ready model.


Motor - SportDrive

The MD250S centre units offer incredibly quiet operation, high efficiency and the best weight distribution - they are nicely centered in the middle of the bike. Their relatively low position adds to the bike's stability in corners, tricky terrain and easier handling. Every e-bike is a joy to ride thanks to this solution. The unit's maximum power is 500 watts, so it can handle steep drops you'll want to climb

Our view:
SportDrive here introduces the 4th generation of the motor, which brings further improvements that are used by a wide range of manufacturers. Quiet and smooth operation, a more powerful engine and 4 types of displays make for a pleasant driving experience. The motor can be found mostly on mid-range electric bikes, where it competes with more well-known brands and breaks through here with a reasonable price tag. The motor has one of the best mounts in the frame - it doesn't just rely on a plastic base, but is fully integrated into the aluminum frame.

Weight - 3.4 kg

Baterie - Sport Drive Phylion 504 Wh

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 Phylion batteries is the 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.

Color Display Sport Drive Color

The largest display you'll find on a Sport Drive unit, with dynamic animations and vivid colors, the display is both expressive and advanced. Far from just showing the basic functions, it's the opposite. It allows all sorts of settings on the unit, so you can use your e-bike more efficiently and perhaps charge your phone via the integrated USB port. You can also use the display to code the bike or set service intervals.
