The demands for the best eMTB are high. It has to climb efficiently, be comfortable to ride, be very stable and composed, yet, on top of that, be a lot of fun on the descents. Also, its integration, ease of use, and motor performance must set the benchmark. Although all the motors perform at a high level, the Bosch Performance CX is unable to keep up with the competition due to the high internal resistance it generates at over 25 km/h. It’s a pity for the Moustache Samedi Race 11: it’s by far the best Bosch bike we’ve ever ridden, but it’s slowed down by the motor. With a price tag of € 5,999, the Trek Powerfly 9 LT Plus is clearly the cheapest bike in this group test. It climbs very efficiently, but is held back on the downhills by a poor choice of tyres and slow handling – you should consider a tyre upgrade in your budget. The Haibike XDURO Nduro descends with the stability of a freight train, but it has to let the competition overtake it when going back up. With its long 180 mm travel and high weight (24.54 kg), it even feels cumbersome on the downhills.
Usually, the cheaper the bike the cheaper the parts. But this doesn’t necessarily mean you’ll be riding around on a rattling tin can. It just means that the bike’s designers took into consideration where they could include lower-level parts without sacrificing safety while putting the money where it counts most—hydraulic disc brakes, decent tires, a reliable e-system. And although the electrical components on some of these bikes might not be plastered with a familiar name, like Bosch or Shimano, that doesn’t mean they’re not capable. Aventon, for example, uses a custom e-system (rather than a complete one) that was pieced together specifically for the Pace 500 because the designers didn’t want to limit the bike’s design specifications.
It was easy, good tools were shipped with the bike. The instructions are nearly useless, though. Like other reviews state, the front fork is backwards in the picture and shipped backwards. The disk brake should be on the port/left side. Flip the handlebar clasp around and leave the dirt guard facing forward. All the cables should flow naturally this way. Pedals were ok to put on, one of the pedals took a minute to get threaded but eventually got tightened.

The Best in Test and Best Value 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!


The least-expensive bike in this roundup and, at 48.6 pounds, our size large Haro Shift Plus i/O 5 is the second-lightest in this group as well. Only the $8,250 Specialized was lighter. The Shift Plus i/O 5 was nimble enough to traverse the most technical trails we could find, and it was much easier to manage on rocky climbs than heavier, longer-travel e-MTBs. The Shimano Steps motor has loads of torque. However, in Trail mode, the bike still lurches forward as soon as you get on the pedals, so you've got to point it where you're willing to go before clipping in. Haro has done well to keep the price down, but we'd pay a slight premium if the bike were to come with a dropper post, which makes it a little less scary to sling a nearly 50-pound bike down a mountain.

With most ebikes the choice of motor defines aspects of the frame geometry and to a lesser degree the suspension characteristics of the bike. Not with new Rock Mountain Altitude Powerplay. With its bespoke motor Rocky has been able to design an ebike that reflects the ride quality of a highly evolved 150mm trail bike. With instant power pickup, extended battery life and streamline proportions it’s not just the handling of the Rocky that will get you charged up for riding. It’s the best bike in this test by some margin, but we had an issue with the motor momentarily cutting and raising questions over it’s reliability.
