Our team of experienced testers rode them for weeks on our local trails—everything from flow trails, to technical singletrack, to our enduro courses. We self-shuttled DH runs and hit the bike path. To understand the differences between them, we rode them back to back on similar trails. We tested them against standard bikes on the same trails in the same conditions. And to evaluate their range, we charged them all and ran them on full power until their batteries flickered and died.
The Bulls E-Stream EVO AM 4 is a new addition to our electric mountain bike test and it didn't take long for our testers to fall in love with this new contender. This bike comes ready to rumble with a beefy enduro ready build with 150mm of front and rear wheel travel controlled by a stout RockShox Lyrik fork up front. Testers found this bike to come alive at speed with stable and confidence-inspiring trail manners that preferred to go fast, and big 2.8-inch wide Schwalbe tires that provided heaps of traction. Bulls has done a good job designing this beast, with a powerful and smooth Brose drive unit cleanly integrated into the frame along with a large 650Wh battery. The motor lays down very smooth power in all of its output settings and is one of the quietest models we tested. The large battery storage capacity provides the longest distance range of all the models in the test so you can stay out longer and ride farther than on models with smaller batteries. The e-bike controls have relatively good ergonomics and an easy to read display.
Electric bikes are here in a big way. Liberated from some of the normal constraints of standard bike design like weight and gearing, e-bike design has exploded; if you can imagine it, someone has built it. From cargo bikes to city bikes, messenger bikes to mountain bikes, road bikes, folding bikes, and even beach cruisers, there is something for everyone. The beauty of e-bikes is that they make the joy of cycling accessible to so many people in so many ways. See at-a-glance reviews below of five of our top-rated e-bikes, or scroll deeper for full reviews of these and other high-ranking options, plus more buying info.
This utilitarian Class 3 (28 mph) road e-bike is smooth and torquey thanks to its Bosch Performance Speed motor. With a drop bar and traditional road-bike position and handling, the CrossRip+ is more suited to long rides on mixed terrain than navigating congested city streets. It comes with a rear rack—for mounting bags, not for attaching cargo directly—full fenders, a kickstand, and integrated front and rear lights (which are powered by the Bosch 500Wh battery). It features a SRAM Force 1x11 drivetrain, hydraulic disc brakes, and wide 700x38mm tires.
Seven batteries keep you powered without adding much bulk to the bike. These state-of-the-art lithium batteries are built to last up to 10 years. A single charge provides a range of 20 to 25 miles. It takes just 4 hours to reach full charge. The battery pack mounts to the frame and sits directly beneath the seat making it less noticeable. 300W motor with variable speed throttle provides powerful propulsion to achieve a speed of up to 20 mph.
Here are two more advantages I see: One is the reduction in scent impact when travelling in my hunting area. My boots are not touching the ground, and I will be moving faster, leaving less signs of my intrusion that might alarm deer. Secondly, I ride a bike quite a bit on trails through wooded areas near my home, and I see that deer react much differently to a person on a bike than they do to a person on foot. They don’t see a person sitting on a pair of wheels as nearly the threat that they perceive a person walking. I’m not sure how much that will be an advantage, but spooking deer while scouting and travelling to and from a hunting location could be reduced.
E-bikes mostly use motors and battery options from a few major suppliers: Bosch, Yamaha, Shimano, and Brose. A few other brands exist, but are less reliable or powerful. Some, like the Yamaha system, have more torque, and others, like Bosch’s Active Line, are nearly silent. But, generally, all four make good options. Look for motor output (in torque), which will give you an idea of total power. Just like car engines, more torque equals more power off the line and more boost to your pedaling. But watt hours (Wh) is perhaps a more important figure to use—it takes into account battery output and life to give a more accurate reflection of power (higher Wh equals bigger range).
Carry Extra Gear - They are built to carry 300lbs and if that’s not enough the trailers can carry an additional 100lbs so you can make it one quick effortless trip in and out instead of a tiring back and forth lugging heavy gear on your back.  Plus the bunch of other accessories available like rear racks and waterproof saddle bags for extra storage on the bike and not on your back.

Mountain biking is all about having fun, right? About getting out there, enjoying the great outdoors, exercising your body and freeing your mind. So what if we told you there was a type of bike that lets you ride further, faster, and have even more fun? One that even made you LOL on the climbs? You’d still have to work for your rewards, but by assisting your efforts, it allowed you to wring every little drop of enjoyment out of your rides. Are electric mountain bikes allowed on trails?
Our twelve-person test team not only tested the most exciting eMTBs of the 2018 season in the cold German winter, but also took them to the south of France for two weeks (we will spare you the mandatory muddy photos at this point). We climbed to the top of peaks, rummaged through deep mud, rode over countless roots and ruts on the way up and even more on the way back down, laughed, cursed, lived through many unforgettable moments, and took the bikes – and sometimes ourselves – to the limit.
The motor is incased in the frame of the bike which gives you better ground clearance. A long lasting eBike, this model comes standard with a Panasonic 48V 14.5AH battery that can be quickly recharged while not in use. This gives you a total range of 20 miles without the need for pedaling.  A thumb throttle allows you to easily control the bike while you are ascending difficult terrain. 
Imagine all the fun you had on your cruiser bike as a kid, and then slap a motor on that bike: That’s what online retailer Bikes Direct has done with the Gravity X-Rod 8-Speed E, and it’s a lovely combination. We’ve been pedaling one of these bikes for nearby errands, and the wide saddle and riser handlebar make for a comfortable, upright riding position. The LED display is easy to read and the 250-watt Bafang rear hub motor is powerful enough to—on the highest e-assist setting—keep you at a steady 20mph in a headwind without much effort from your legs. The 27.5x2.4-inch WTB Riddler Comp tires smooth out bumps in the road, and the Shimano hydraulic discs are a high-value inclusion at this price. And despite the fact that it’s a beach cruiser, the 8-speed Shimano Altus drivetrain makes it capable on hilly terrain, too.
The strong and sturdy frame makes this mountain e-bike very heavy compared to the other ones in the market, but despite this fact, it is a great purchase. You can ride it on bumpy terrain or in the city if you wish to. The 21-speed option allows you to choose the preferred speed for you. The powerful motor that is integrated into the frame of this e-bike what makes the Sidewinder a great companion in the outdoor adventures. What is the best electric mountain bike to buy?
