The bikes we tested all use a different e-bike motor system, and the controls, the primary user interface, are an important element we rated but didn't weight as heavily as some of the others. Each motor system and its associated controls are slightly different. Our primary interest is in how user-friendly is it to interact with the system, how intuitive and ergonomic are the shifters, how good and easy to read is the display, and how easy is it to charge the battery? Each drive system also has a smartphone app that is intended to allow the user to fine-tune the motor's support settings, create custom settings, monitor battery charge and health, and a whole lot more. We don't feel the apps are necessary for the use of any of these e-MTB's, but those with an affinity for technology or personalizing your ride may be inclined to use them.
The original Power Plus model was one of the most popular in its class, introducing the joy and practicalities of e-bikes to a huge audience around the world.  The CX1 builds on that success, adding a NEW more powerful brushless motor, a NEW upgraded battery, a 21-speed gear system, and improved reliability.  The steel frame, strong brakes, suspension and quick-shift gears offer all the qualities of a premium mountain bike with the added feature of three pedal assist modes.
Levo Battery Charger is a 4A battery charger. It is better than industry average of 3A chargers but not that impressive neither. I would expect at least in their expensive models such as Men’s S-Works Turbo Levo to see a 6A charger. Anyway it isn’t bad, actually better than what most e-bikes offer. Maybe they can offer a fast charger as an accessory who need to charge their e-bikes several times a day without wasting lot of time.
I haven't given a full benchmark on battery life as I haven't gone without pedaling just using the motor. I live in a hilly place and I need to pedal to make it up some hills. But initial impressions are good. My hilly trip to the beach with kids in tow was about 13 miles round trip and I made it down to 3 of 5 bars on the battery. The battery does go down when the motor is under stress but levels itself when back on level ground. Battery is looking good. 

I bought this bike with intended use on my hunting farms. I’ve ridden it now off road several times, and to say I’m blown away, is an understatement. This bike simply blew me away on all fronts. The motor is super strong and pulls me around great. I’m 6’2 210 so I’m not a small guy either. Like others have said, if this thing doesn’t make you smile the first time you ride it, you’re just not a happy person!!!!
EThe Best in Test and Best Value Electric Mountain Bike tips do not result from the sum of star ratings, but by the assessment of the entire test team, taking into account the overall concept of the bike. It would be methodologically wrong to only add up the star ratings to make a final judgment in a scoring system – saying that something is “good” will not help anyone if they don’t know what it is for and for whom it is “good.” For this reason, we give a clear recommendation in every test result for which type of rider and purpose the bike is suitable and which not. The bikes themselves are as individual as the riders are – we just want to provide you with all the information you need to make a well-informed decision before buying. Here’s to long-lasting fun!
