Charlie Russell – is the best known Grizzly bear conservationist and activist – known for his decade-long work in Kamchatka, where he taught local guides how to lead bear watching trips. He began buying orphaned grizzly cubs from zoos, taking them to remote areas of Kamchatka and teaching them how to live in the wild .

With the support of electric propulsion, Russell vehicles will never again make difficult climbs and long distances a problem for you. The electric motor and capacious battery will get you to your destination faster and easier. If you ever had the fear that a bike trip would be too much of a burden, the Russell is the best remedy for your fears.

Russell  ebike in any version of equipment, is based on aluminum-steel frame. The Russell frame as well as all other BearEbike frames are manufactured from start to finish in Poland. Vehicle weight depending on the final version of equipment is approx. 55-60kg.


BearEbike Russell

A version of the BearEbike Russell vehicle not approved for public traffic due to its specification. Not homologated, intended for off-road use only.

All BearEbike Russell vehicles feature a thumb throttle.  Motorcycle-style twist grip throttles are not fitted for safety reasons (on each vehicle maximum torque is available immediately from 0 km/h).

The BearEbike Russell is a non-homologated vehicle intended for off-road riding only, e.g. forest, fields, meadows, mountains and private land.

All vehicles in the BearEbike Russell series are designed for people who prioritize acceleration and top speed over maximum range on a single charge.

If you would like more information on the configurations shown, or would like to configure the vehicle to suit you – please contact us.

Vmax – the maximum speed of the vehicle without the electronic speed limiter measured with a fully charged battery – on flat terrain, in windless weather, at 15°C and with a 75 kg rider. The maximum speed of the Ultimate version of the vehicle is achieved under “ideal conditions” when measured on a load dynamometer test stand. According to our experience and measurements, due to air resistance and aerodynamics it is difficult for this vehicle to exceed 140km/h on tracks designed for this purpose.

Acceleration 0-50km/h – acceleration obtained during the measurement with a fully charged battery – on flat terrain, in windless weather, with temperature of 15°C and rider’s weight of 75 kg. The measurement value is obtained from the combined mean of the GPS measurement and the measurement based on the engine Hall sensors. The acceleration value may slightly differ in real world conditions and it depends only on the driving ability of the user. Acceleration value for Fat Bear Ulltimate is approximate because we lack the ability to ride this vehicle and get a consistent and repeatable result (and not to hurt ourselves).

Range – realistic range value given for each vehicle type. Minimum range is the minimum range you can achieve by riding practically all the time in the upper battery load range. The maximum range is given when travelling at a speed of up to 25km/h using a traditional propulsion system and an electric motor in the form of pedal assistance. In both cases range is measured from a fully charged battery – on flat terrain, in windless weather and with temperature of 15°C and rider weight of 75kg. If you want to know the exact range of our vehicle for your weight, terrain characteristics and driving style – please contact us.
