Most brands list their bike's power, but avoid putting too much emphasis on the number— there is no standard for measuring this, so the performance can vary wildly. Every motor on our list is rated to a continuous, or nominal, power output of 250 watts. But even this number isn't always accurate. Instead, look for torque, which measures how much rotational force is being applied to move the motor. It's the oomph, grunt, or kick you feel when you step on the pedals. More torque means faster acceleration and increased assistance.
With mountain bikes already sporting hefty price tags, the cost of adding an electric pedal-assist motor might be enough to send the value-conscious rider's head spinning. In many cases, you get what you pay for and the most expensive models are the highest performing. This isn't always the case, however, and bikes like our Best Buy Award winner, the Giant Trance E+ 2 Pro cost less and perform nearly as well as the more expensive competition.

Recovery from injury will be faster – Injury and biking go hand in hand. When you are hurt, you cannot ride a regular MTB although biking can actually help your body to gain the fitness. An e-bike can be your best companion to your fitness-regain journey. As you can choose the assistance level, it will be easy to keep up with your trail mates without pushing yourself too hard.
Scott’s Genius eRIDE 920 is another bike with Shimano’s excellent Steps E8000 motor. The narrow width of this motor—same as a standard Shimano mountain bike crank—is a nice feature, as is the support and customization offered by Shimano’s e-Tube apps. Boost mode lets you cruise comfortably at up to 20 miles per hour on pavement, while Trail mode doles out torque more smoothly and increases range. But compared to the Bosch in e-mtb mode (comparable to Shimano's Trail mode), Shimano’s faster and harder-hitting torque is less desirable for navigating technical terrain. The 29-inch wheels and 150mm of travel provide the ability to straight-line some really gnarly stuff. This bike is meant for riding big and riding hard. The big travel, long trail, and slack head angle give you a bike that loves to go straight and gobble up rowdy trails. And despite being such a long bike, it still handles technical terrain well.
The 250W motor and the 36V battery is built into a frame that also includes 26 inches wheels, anti-slip power-off brake, and Shimano 21-speed shifters. An integrated LCD screen shows power, speed, battery charge, and a few other statistics. It is suitable for adults as it can carry up to 360 lbs weight. However, the bike itself is almost 51 pounds, so keep that in mind.
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!
