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.
Do the e-bikes don’t have any downside? Well, they do but it’s nothing of a deal-breaker. Well, the only real issue could be forgetting to plug in and charge the bike. The bulkiness could be another issue but the extra weight actually helps when going downhill. The maintenance is not much of a hassle too, as it does not require any extra care than a regular MTB.

Trevor Porter, Kona's e-bike manager, said that motors can demand longer chainstays and adding batteries to downtubes can require larger headtubes, increasing stack height. This is common across the range of e-mtbs we tested. The reach and head tube angle tend to remain similar to standard bikes, but the chainstay length, head tube length, and stack height are generally increased.
With 170mm travel, aggressive angles and Shimano’s superbly calibrated STEPS motor, the Focus Sam2 is an enduro bike with a built-in shuttle. With the bolt on TEC pack you really can climb to new heights, but without it the smaller capacity internal battery means you need to be ultra economical with your energy use. It’s also frustrating that the internal battery can’t be removed easily for charging. By far the biggest frustration with the Jam2 though is that the sizing isn’t very generous and standover clearance is limited. It’s still a great e-bike, but when you’re spending this much money, you can afford to be fussy.
The frame is constructed of 6061 aluminum that’s more responsive with some bit of flex to it. A step-thru design makes getting on and off a breeze. The frame supports a more upright posture for improved comfort and visibility. A front fork suspension and rear spring suspension make for a smooth ride on uneven surfaces. It actually adds an aggressive look to the overall design.
With its steep seat tube angle and powerful motor, the Rotwild E+ Ultra masters even the steepest climbs. Its high centre of gravity, however, negatively effects downhill handling. The GIANT FULL E+ 0 is a very solid eMTB where what you see is what you get, although the rather slack seat tube and bulbous-belly isn’t exactly pretty. Not so with the FOCUS SAM²: With its clean silhouette it is a bike for design lovers. But only if you get by with the small integrated battery. As soon as you mount an additional battery, not only the appearance suffers, but also the handling. The BMC Trailfox AMP has minor weaknesses in the componentry, finish and downhill handling – at a price of € 12,000 we expected considerably more. The Thömus Lightrider E1 fares better, it’s no bargain either, but the handling is outstanding. It’s a pity that the bike isn’t available outside of Switzerland. Another exotic specimen is the FANTIC XF1 Integra Enduro 160. The bike from the Italian motorcycle brand can’t deny its roots, tremendously composed and capable on the descents, though it cannot keep up with the competition when going back up – the 180 mm version of the Fantic is significantly better overall.
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).
While we liked the value, component specification, and versatile all-around performance of the Trance E+ 2, it wasn't all gold stars. E-bikes are heavy, that is a given, but the Trance is a little heavier than most at 52 lbs 3 oz. This weight is one of the reasons this bike feels somewhat sluggish at times, especially in low-speed sections of trail. It also has mediocre e-bike controls. Sure, they are functional, but the all-in-one control's display in the form of small LED lights is difficult to see by the left grip and near impossible to read when riding in bright light conditions. Beyond that, we feel the Trance E+ 2 is a quality e-bike offered at a reasonable price.
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.
When you hear “electric bicycle” you normally don’t think off-road. Add to that the phrase “hunting” into the mix, and all of a sudden the idea of an “electric hunting bicycle” seems a little strange. We don’t blame you because when manufacturers started producing e-bikes decades ago that was certainly the case: any bit of moisture or debris could short even the most powerful electric bike motor back in the day. How are you supposed to hunt with something that can’t even go off-road?

All the electric bikes need to have the best braking system to keep them safe for all users. With this quality E-bike, you are assured of a safe ride thanks to the front and rear disk brakes. This makes it easier to stop the bike even when at a higher speed. Besides this, the bike also lasts for years due to the high-strength carbon steel used in the construction. This makes it a great investment for anyone looking for the best electric bike. What's the best electric mountain bike?
