The US manufacturer Optibike has presented the R22 Everest an e-bike that can travel up to 489 kilometers under optimal conditions without having to be connected to the power grid. At the same time, it is one of the most expensive e-bikes on the market.
Features the R22 Everest is equipped with two batteries, which together weigh sixteen kilograms and hold 3,260 Wh. They are thus significantly larger than ordinary e-bike batteries. The model from Optibike is thus clearly designed for longer tours, but not for ordinary city traffic. The batteries are installed in the down tube of the carbon frame. However, they protrude a bit to the left and right from the frame.
A switch can be used to select which battery is to be used. Thus, it is possible to switch to the second battery only when the first one is completely used up. In terms of estimating the remaining range, this should make sense.
Up to 489 kilometers range
However, the stated range of 489 kilometers is only achieved under ideal conditions that are relatively far removed from practical use. It was calculated from the following scenario: the rider weighs 72.5 kilograms, rides at a constant 24 km/h and has the pedal assistance set to low. At higher speeds, as well as with stronger pedal assistance, the range drops significantly. At 45 km/h, it is about only 160 kilometers.
Meanwhile, the bike is powered by a 1,700-watt mid-mounted motor that delivers 190 Nm of torque and is connected to a 14-speed hub gear. There are also two suspension forks with 200 millimeters of travel and two 27.5-inch wheels each. The total weight of the bike is 42 kilograms.
Price and availability
The net price of the e-bike is around 17,000 euros. It is not available to order in Germany. Interested parties must therefore have it imported, which involves additional costs.
