It also uses a new cell chemistry to enable greater density (the amount of energy storage per pound), and to operate at cooler temperatures. This year’s version includes a new battery pack, dubbed the R5.8 for its 5.8 kilowatt hour capacity. A comparable gas bike would cost around fifteen dollars to fill. To charge up the battery fully costs far less than a dollar. An average American house uses around five times this much energy in a day. The Redshift MXR uses a 5.8 kilowatt hour (kWh) battery. The Redshift MXR motor spins at 14,000 RPM, producing 50 horsepower, twenty percent more powerful than the previous year’s Redshift MX. The powerful R5.8 lithium ion battery which gives the Redshift MXR bike it’s kick (Source: Alta Motors) It weighs in at 259 lbs, and takes an hour and a half to rapid recharge, or three hours with standard charging at half the voltage. The Redshift MXR goes for around $12,000, plus accessories. It also costs several thousand dollars less than last year’s MX. The new model weighs eight pounds less than its predecessor, and features brand new front and rear suspension. It uses a single-speed transmission, and sports an aggressive look. The MXR reaches a top speed of around 65 mph. The Alta Redshift MXR boasts some impressive technology. You can see a map of dealers at the company website, and request a demo ( ). The national network spreads out from its San Francisco headquarters to the east coast, with plentiful power sports dealers across the country. You can acquire an Alta Redshift MXR electric dirt bike through the company’s dealer network. The electric motor frees engineers to make design choices they could not make with a gas bike, for example giving the Redshift a uniquely smooth and stable ride on all terrains. Initially suffering from very high weight and low range, successive generations have narrowed the gap, and the performance and maintenance advantages are gaining converts. While electric dirt bikes are still relatively new on the scene, they are evolving rapidly and gaining traction. The Redshift MXR is one of the most powerful and technologically advanced electric bikes, pushing the entire segment forward. These rides are gaining traction, as the technology advances rapidly. Prices start as low as $2,500, with varying features such as battery size and chemistry. Alta’s new electronic bike definitely doesn’t skimp on performance (Source: Alta Motors)Įlectric dirt bikes by other companies include the Torrot e10, the Zero DS and FX models, and the KTM Freeride E-XC. As they boast, an electric dirt bike “requires no air filters, oil changes, or top end rebuilds, so you can spend less time wrenching on your bike and more time riding”. The Alta website promotes it as good for beginning trail and woods use, or as a full-fledged competition motocross bike. The Redshift MXR is designed as an electric equivalent to a gas 350 bike. Then there are the powerhouses like the MXR dirt bike. Another category resembles a scooter, meant to be faster and more comfortable than a bicycle, but costing more and not practical to pedal without the electric motor. Most but not all of these enable the rider to use it as a regular bike while the motor is off. These drives can be controlled by hand throttle, pedal assist, or a combination, depending on the design of the bicycle. The most common ones operate similarly to traditional pedal bicycles, but with the addition of electrical drives. Several different varieties of electric bike have been invented. Unlike most electric pedal bicycles, however, which are designed to be street legal and have hard speed limits, you can push the Redshift MXR as hard as you and the bike can physically handle. At the very upper end, the bike includes self-limiting speed to prevent overheating the circuitry. The lower power setting offers a gentler ride, and considerably longer range. Riding the MXR, you can choose among four speed settings, similar to an electric bicycle. An electric bike engine runs much cleaner than a traditional motor (Source: Dirt Rider)
