During the Fat Bear Week, 12 bears from Katmai National Park compete against each other. Fans compare their photos and vote online for their favorites starting Sept. 30 for one week. In the 2020 final, a bear named 747 faced off against a bear named Chunk. The winner received more than 47,000 votes, while Chunk received more than 21,000 votes.
Bears living in Katmai National Park weigh up to more than 450 kg after summer. During hibernation, they can lose a third of their body weight. In the summer, they congregate along the Brooks River, where they hunt salmon swimming to their spawning grounds. In 2020, there were almost no people along the river. Usually there are about 500 visitors a day during the peak season, but during the pandemic their numbers dropped to 50-100. This gave the bears better access to the river.
The first event dedicated to Alaska's fat bears was held in 2014 as Fat Bear Tuesday. It later evolved into a week-long competition to raise awareness about wildlife in the park.
All Fat Bear LEGAL vehicles, as manufactured, are approved for use on bike paths and public roads in Poland and EU
Fat Bear Electric Bikes intended for use on cycle paths and public roads - depending on the version, have a nominal voltage of 48V to 72V and nominal power of 250W and have a manufacturer installed nominal power limiter. The value of the nominal power limiter is dependent on the destination country in which the vehicle is to be used.
By ordering a Fat Bear vehicle, you can be assured that your vehicle will meet all the legislative requirements of an EU country of your choice.
By default, Fat Bear vehicles have pedal assistance up to 25km / h or other compliant with national regulations, and do not have a thumb throttle.
Ebikes with thumb throttle are not allowed to ride on bike paths in Poland, however since you will be ready to travel the world on Fat Bear LEGAL/LEGAL+ branded vehicles, each vehicle has a thumb throttle extension/connector on the handlebars to make it easier for you to install thumb throttle if you ride your ebike in a country where thumb throttle use is legal.
All Fat Bear vehicles can be customized to fit the regulations of a specific country. When ordering a Fat Bear vehicle, please let us know in which country the vehicle will be operated so that we can make sure it will comply with the regulations of the country in which you are located.
Fat Bear NITRO / NITRO+/ULTIMATE
A version of the Fat Bear vehicle not approved for public use. The Nitro series vehicles are not approved for bike paths, but their appearance is not significantly different from the Legal series models.
All Nitro 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 Fat Bear Nitro is a non-approved vehicle intended for off-road riding only, e.g. forest, fields, meadows, mountains and private land.
All vehicles in the Nitro series are designed for people who prioritize acceleration and top speed over maximum range on a single charge.
When choosing a Nitro Series vehicle, determine exactly where you want to go with it. If you have experience in motocross - let us know, it will help us match the equipment to your riding style.
The Nitro version differs from the Nitro+ in features such as front and rear suspension and electric motor technology.
If you would like more information on the configurations shown, or would like to configure the vehicle to suit you - please contact us.

Vmax with limiter - maximum speed of the vehicle with electronic speed limiter engaged. The value of electronic speed limiter is set for the market/country in which the vehicle is to operate in accordance with current regulations for electric vehicles such as ebike, epedelec or moped
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.
