It wasn't all gold stars for the Bulls, however, as the larger battery storage of this bike makes it the heaviest in our test. This heavyweight rig is far from nimble or agile, giving it a more one-dimensional performance on the descents, and hampering its climbing abilities in technical sections or tight corners. Its charging port is also recessed into the frame making it one of the least user-friendly, and while we did like their e-bike controls, they couldn't quite match the ergonomics or display of some of the competition. Overall, we had a blast riding the E-Stream EVO AM 4, read on to find out how it compares.
The Ghost SL AMR scored relatively well in this metric, with a small digital display mounted by the stem. The YT Decoy uses the same drive unit and controls as the Ghost and scored equally well for having easy to reach controls and a digital display mounted by the stem on the handlebar. The Trek Powerfly's all-in-one Bosch Purion shifter and display unit was easy to read and had a bright screen, but was in a less visible location on the left side of the handlebar. The Bulls E-Stream has a similar system to the Trek, but with better button ergonomics and more information available on the display on separate screens.
Electric bikes are generally heavier than normal bikes. This is due to the battery packs and additional motors which usually makes them about 20 pounds heavier. The weight of the bike can mean better traction in downhill and better stability to the ground, while on the other end, they can make them hard to maneuver with on flat grounds. Therefore, the weight of the bike you get should be based on how and where you intend to use it. The best one to get should be one that is heavy yet have a motor that is powerful enough to support the weight. 

When you buy a new bike at full RRP from rutlandcycling.com, you can now benefit from the added reassurance of our Rutland 30-day test ride. Once your new bike arrives, you can ride it as your own for 30 days, and we're confident you'll love it! However, if it's not right for you, we'll exchange it for another model. (There's a nominal charge of £10 for us to collect your bike - just make sure you keep the box your bike arrived in.)

As I said before, going up hills might require some pedaling, but it is SO MUCH EASIER with the motor running. I feel like a higher voltage is used on level 3 pedal assist than can be gotten just using the hand turn, though. It takes a few pedals for the pedal assist to kick in which can be annoying, but it does save some battery on initial acceleration. You also have to be careful pedaling around to park the bike or at a street corner waiting for traffic because you DO NOT want the motor to kick in and send you into a workbench or worse ... oncoming traffic.
In our head to head range test, the Rocky Mountain took the win by traveling 20 miles and 4,297 vertical feet. It is worth mentioning that our tester felt that he worked a little harder while range testing the Rocky Mountain than the other bikes we tested. The Giant wasn't far behind at 19.02 miles and 4,000 vertical feet, and the YT Decoy almost tied that with 19.01 miles and 4,039 vertical feet. The Specialized was nipping at their heels with 18.71 miles and 3,949 feet. The Ghost Hybride SL AMR was the least impressive with a range of just 16.75 miles and 3,559 vertical feet. The outlier in this comparison is the Bulls E-Stream with a 650Wh battery. We were not able to test the Bulls directly against these other competitors, but we did notice that you can ride it significantly farther than any of these other contenders. During one of our test rides, we rode the Bulls 24 miles and 4,500 vertical feet, and the battery still wasn't depleted. More battery storage equals longer rides; it's just that simple. 

One of the primary purposes of an e-bike is transferring power from the motor to the drivetrain to "support" your regular pedal stroke. All of the different drive units do this in relatively the same way, although subtle differences in their power output make them all feel slightly different. It is important to note that all of these systems work pretty well; the differences between them are relatively subtle but noticeable. We tested this metric primarily based on feel, as opposed to any sort of scientific measurement, and our testers could all notice the differences between the various models. All of the e-bikes we tested have several support modes offering varying levels of pedal assist support.
The Pivot Shuttle breaks the e-mountain bike mold. It’s Shimano Di2-equipped and features a carbon fiber frame with 140mm of rear travel, a 150mm fork, and a 150mm dropper post. A Shimano STePS e8000 drive unit, paired with a 500Wh battery, provides 20 mph of pedal assist, so you can skip the lift line when you hit the bike park and zip right to the good stuff. The 27.5-inch wheels are nimble and eat up nearly anything in their path, and the massive 2.8-inch tires have huge knobs that grip the trail like Velcro.

Haibike ships the HardNine with 29-inch tires, 180-millimeter hydraulic disc brakes, a 100-millimeter front suspension fork, and a nine-speed Shimano shifting system. The bike’s LCD readout is affixed to the handlebars and displays the current speed, level of charge, remaining range, and current pedal assist mode. The company says the battery can be completely recharged in just four hours, minimizing downtime between rides.
The RadCity is a bike that’s been optimized to help you conquer the urban landscape. A big 48V battery gives you an estimated range of between 25 and 45 miles of e-assist from the 750-watt motor, which packs enough acceleration to get you out of dicey situations in traffic. There’s also a wattmeter to help you manage your power consumption on the LCD display. A welded-on rear rack holds up to 60 pounds of cargo, and puncture-resistant Kenda K-Rad tires keep you rolling over precarious debris. Commuting essentials include lights (the tail light also functions as a brake light), fenders, and a rear-mount kickstand.

Prodeco V5 Phantom X2 8 Speed Folding Electric Bicycle is constructed and tested in the USA. Travelling on a bike is sometimes very comfortable to get some fresh air. This bike is the one that is designed by keeping your needs in mind. It allows you to fold the bike in a compact form and can carry it in the office, basements, flats, etc. The Prodeco V5 Phantom X2 bicycle has avid BB7 disc brakes, 500-watt motor, 12Ah battery, and rigid frame. The manufacturers offer a lifetime warranty on the frame and 2 years on components.
Specialized has e-bikes figured out. Its e-bikes are better looking and better sorted than almost anything else. This Turbo Levo has a clean interface: just a mode switch and a few LEDs for status. To dig deeper, you use Specialized’s Misson Control app, which lets the user customize the motor’s tune, and has a clever Smart Control mode. This mode lets the rider set and time or distance, and the amount of reserve they want to be left over. The app then automatically adjusts the motor’s output to meet those settings, reducing battery anxiety. The custom motor is extremely smooth and quiet, with awesome torque. We found the highest mode too powerful for finesse riding, but great for flying up smooth climbs and cutting time off transfers. The e-bike tuned RockShox fork is somewhat harsh, but the rest of the parts are excellent and suit the bike’s capabilities—something we can’t say that about every e-bike.
A couple of issues I see with the use of the bikes: First of all, once I arrive at my treestand, I need to find a place to hide it so it doesn’t attract the attention of deer. Secondly, when I have a lot of gear to haul in and out, will the bike and trailer be able to handle it all? Will I be able to pull a deer out with the bike, or will it mean one more trip back and forth to my truck?
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. Who makes the best electric mountain bike?
