For something with a bit more professional-feeling, the Jetson Adventure Electric Bike comes to mind as one of the best electric mountain bikes. Why we say that is due to its 9 levels pedal assist and 21-speed transmission system, which give great control over terrain. That\u2019s in addition to a wonderful LCD display that offers metrics only professional riders are concerned with.\r\n\r\nWhy We Like It - Jetson Adventure Electric Bike\r\nWith 9 levels of pedal assist and 21-speed transmission system, there\u2019s not a single mountain that\u2019s beyond your reach when you\u2019re atop the Jetson Adventure Electric Bike.\r\n\r\nDurability & Build Quality\r\nBeing made of aluminum, the Jetson Adventure Electric Bike is built to be both sturdy and lightweight, as opposed to heavy and clumsy. Despite its aluminum alloy frame, it can still bench press 300 lbs, easily. The seating is particularly comfortable, alongside its slightly flexible seat tube. The handlebars are basic, but are textured for better grippage\r\nPerformance (Speed & Acceleration)\r\nThe 250 watt hub motor doesn\u2019t sound like much, but it actually gets the bike up to 20mph, matching the NCM Prague Electric Mountain Bike in speed. The MVP, however, is clearly the 21-speed transmission system. That provides unparalleled control over terrain.\r\nRange & Battery\r\nBattery life could use some help. Using pedal assist\u2014you\u2019re pedaling some\u2014means you\u2019ll get 30 miles on a single charge. Electric mode is about half that. The battery recharges in six hours and is removable, but can be hard for you (and thieves) to get at.\r\nSafety Features\r\nAside from solid and confident disc brakes, the interactive LCD display is the best safety feature the Jetson Adventure Electric Bike has. It keeps track of various metrics, like current speed to miles traveled. And if you\u2019re in the mood for night riding, it\u2019s fitted with both front and back lights, which the Cyclamatic Power Plus CX1 Electric Mountain Bike lacks.\r\nValue\r\nThe Jetson Adventure Electric Mountain Bike is an overall great professional mountain bike. Given its speed and overall well-designed build, it serves as a marker for riders who\u2019re ready to move away from basic-functioning mountain bikes, to information-heavy machines. We only suggest you replace the battery, if possible. For beginners, start with the ANCHEER Folding Electric Mountain Bike.\r\nJetson Adventure Electric Bike Wrap Up\r\nDespite a so-so battery life, the Jetson Adventure Electric Bike is still a great bike, and one better left in the hands of a professional. It\u2019s they who\u2019ll find the best way to handle the 21-speed transmission system and 20mph. But given that it has 9 levels of pedal assist also opens up for newcomers to the mountain scene.
