Product description

Please note: all of our bike models come with an EU standard brake setup. This will need to be reversed to comply with UK cycling standards.

The Serious Bear Rock 29” is a powerful and sturdy hard tail electric bike which features a high-performance Bosch motor.

Boasting high specifications and a solid design, the Bear Rock is ideal for those looking for a versatile bike. The powerful Suntour XCM 100mm front suspension fork absorbs shock on the trails while the motor takes off the strain when you need it most. Quality components include a 9-speed gear system and powerful disc brakes, both supplied by Shimano. The sporty Schwalbe tyres offer excellent grip and control.

The Bosch motor system is controlled via a clear and intuitive display mounted on the handlebars. It is designed for long distances and the battery has a long life.

Details

  • Schwalbe Smart Sam tyres for sporty use
  • Shimano's powerful disc brake
  • Suntour XCM 100 mm spring travel with lockout
  • Shimano Alivio 9-speed shift
  • Note: Contrary to the picture the bike is delivered without remote lockout - suspension fork has only one lockout at the suspension fork
  • pedals included in delivery

The Performance Line CX from Bosch takes sporty e-biking to a new level - the drive system allows you to experience the incomparable powerful Bosch Uphill Flow. You can look forward to a noticeable increase in performance, up to 75 Nm of maximum torque and lasting strength up to high pedaling frequencies for sporty acceleration even in alpine terrain.

Range

How many miles will my battery last?  
Can I get 50 miles from one battery charge or even 120? For those interested in buying an e-bike, this is a very important question. Manufacturers try to be as realistic as they can about possible ranges your e-bike may manage on one complete battery charge. In practice, however, the maximum range depends on many different factors.  As well as the type of motor you have, factors include the energy content (400 or 500 Wh), handling and age of the battery. However, the rider's weight, sitting position, riding style (starting frequency, cadence) and selected support levels (Eco, Tour, Sport, Turbo) all greatly influence the range. Last but not least, the track profile (uphill or flat), the ground (road or terrain), wind (headwind, tailwind) and even tyre profile effect distances possible. This makes it extremely difficult to provide precise and reliable information.
