The Rocky Mountain Altitude Powerplay has been on the market for several years now and does things differently to most eMTBs. The Canadian brand developed its own powerful, tunable motor and combines aggressive geometry with looks inspired by non-motorised mountain bikes. Read on to find out how the Canadian concept performs on the trail.

Rocky Mountain Altitude Powerplay Carbon 90 Rally Edition | Dyname 3.0 Drive/672 Wh | 160/150 mm (f/r) | 22.72 kg (size L) | € 9,000 | manfacturer website

At the heart of the Altitude Powerplay is the Dyname 3.0 motor that Rocky Mountain developed in conjunction with Propulsion Power Cycle. The peculiarity here is that the motor isn’t directly connected to the cranks. Instead it drives the chain directly which unfortunately requires a series of chain tensioners that make the whole mechanism a lot louder. Rocky Mountain have developed a new slider which is claimed to reduce noise and can also be retrofitted to older models. While it makes the Altitude Powerplay a bit quieter, it still sounds like you’re being driven by a coffee grinder. The sleek 672 Wh battery is firmly integrated into the down tube, allowing Rocky Mountain to keep the design of the bike nice and slender. Together with the matching Rocky Mountain team colours, it’s a good looking bike. However, the plastic cover for the motor, the cable clutter at the cockpit and the careless cable routing on the rear triangle somewhat dampen the impression.

Components, weight and technical details of the Rocky Mountain Altitude Powerplay Carbon 90 Rally Edition

The 160 mm travel FOX 36 GRIP2 fork and the FOX FLOAT X2 shock offering 150 mm travel leave nothing to be desired. The model we tested came with a MAXXIS Minion/Aggressor tire combo with the light EXO carcass. However, in future Rocky Mountain will spec the Altitude Powerplay Carbon 90 Rally Edition with the heavier and more robust Doubledown carcass on the front and rear. Except for the outdated 1×11 XT drivetrain from Shimano, there is nothing to fault in terms of componentry.

Custom fit
Rocky Mountain have put a recess in the carbon frame in order to accommodate a water bottle.
Standard bottom bracket
The Dyname 3.0 motor sits in front of the cranks and is connected directly to the drivetrain via the chain.
Sounds like a coffee grinder
Despite the new Silence Slider, the tensioners still make a lot of noise. Too bad since the motor itself is almost completely silent.

Specific Features

Integrated battery
The 672 Wh battery is firmly integrated into the frame and keeps the Altitude Powerplay looking nice and slender.
The remote is small, compact and the operation is intuitive: coloured LEDs provide information about the support mode and battery status.
The cover for the charging socket often comes loose. You have to fish dirt out of the charging socket before plugging it in – it’s just annoying.
Our model came with Exo casing MAXXIS tires, which is too thin for the intended use of the bike. Rocky Mountain have already made improvements here and for 2020 the Altitude Powerplay comes specced with the Doubledown casing – thumbs up!

Geometry and size of the Rocky Mountain

The geometry figures of the Rocky Mountain are very close to the test field average. Except for the very long 480 mm seat tube, that is.

The Rocky Mountain Altitude Powerplay Carbon 90 Rally Edition on the trail

The pedalling position on the Rocky Mountain Altitude Powerplay Carbon 90 Rally Edition is comfortable, making it ideal for longer outings. When going uphill, the slack seat tube angle (74°) positions the rider far over the rear wheel. Preventing the front from lifting on technical climbs requires a lot of physical effort as you have to shift your weight all the way forward. The tuning of the motor is unique and fundamentally different from the rest of the test field: the motor stops assisting very abruptly as soon as the rider stops pedalling. It takes a technically skilled rider with good pedal timing and good line choice to have fun on the climbs and harness the full 108 Nm torque of the Dyname motor.

With its mountain bike-like handling, you could almost forget that you’re riding an e-bike. Unfortunately, the omnipresent coffee grinder noise of the motor won’t let you forget.

When going downhill, the compact geometry makes you tense up and you have to actively shift your weight around to stay on top of the bike. We recommend adding spacers under the stem to minimise those over the bars feelings.While it can feel a bit touchy in the hands of a less experienced rider, experienced and aggressive riders will be able to make the most of its agile and playful handling. It is compact, manoeuvrable and resembles the character of non-motorised trail bikes more than any other ebike in the test field – even the agile Canyon can’t keep up. Unfortunately, the chain slaps the bottom of the chainstay, creating even more noise and chipping the paint. The suspension performs excellently and offers abundant reserves when the trail gets fast and rough.

The Rocky Mountain comes to life under the guidance of an experienced rider. For beginners, the handling can be a bit touchy at high speed.

Tuning tip: Earplugs for the noise 😉

The Rocky Mountain Altitude Powerplay Carbon 90 Rally Edition is a great eMTB for all competitive and experienced riders who attach great importance to agile and lively handling. Its design, geometry and downhill performance comes very close to that of a non-motorised mountain bike, with a few drawbacks. However, it also rides like a non-motorised mountain bike on the climbs. Unfortunately, the loud noises of the motor quickly destroy the illusion of unnaturally powerful legs.


  • very playful
  • design
  • slender look


  • loud motor despite the new Silence Slider
  • motor cuts out abruptly
  • for experienced riders only
