The extra grip a 50lb e-bike normally helps to prevent overshooting corners when on the brakes, and bring pure DH-bike-like fun factor on the steepest trails. This electric Orange, however, rides more like a ‘standard’ enduro bike with a motor, which could be good or bad, depending on your expectations and riding style. It’s built tough and delivers stacks of fun in less time than any regular bike can. Adding a motor hasn’t upset Orange’s superb geometry.

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.

Due to high total weights of over 20 kg, it doesn’t matter whether the scale stops at 21.44 kg or 22.2 kg for a modern eMTB. In our test, the difference between the lightest and the heaviest bike was just under 4 kg. This is not to be ignored… but a little extra weight in the form of functional, reliable componentry is better than an ebike designed and constructed to be as light as possible, at all costs, but which ends up in the workshop more often than on the trail.

Just like all Rambo models, this unit comes standard with a durable aluminum alloy 6061 frame.  This bike has an energy efficient 350-watt Bafang rear hub motor that is powered by a LG 36 volt 10.4AH battery.  The R35OJR comes in matte black and has a KT-LCD3 digital display that will allow you to keep up with important information such as the battery level. 
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.
As these fat tire bikes have showed up at hunting shows over the last year, I have viewed them more with curiosity than anything, but I as I considered how they might fit into my bowhunting, I am about to take the plunge. I bowhunt whitetails on public land in several states each year, and that often involves getting way back into a property to get away from the crowds. For example, I have found a location where I have killed a couple of mature bucks on public land in Kansas, but it’s a walk of more than 1.5 miles. That’s a long haul before daylight and after dark. Once I shoot a big buck back in there, the distance seems to become even longer.

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.
