ROCKY MOUNTAIN ALTITUDE POWERPLAY ALLOY 50 (2020)

If you’ve landed on the Altitude Powerplay Alloy 50 page, chances are you know the brand and its reputation. You might also know that the Rocky Mountain Powerplay is one of the best E-Mountain Bikes (E-MTB) in the industry.

And I’ll explain why.

ABOUT THE POWERPLAY PROJECT

Specifications and the components that an E-MTB is equipped with do have an impact. But not as much as the drive system - it is an electric bike after all.

And not all electronic drives are made the same.

Rocky Mountain partnered with another Canadian manufacturer 10 years ago to develop what would today be one of the most advanced E-MTB drive systems in the world.

10 years and 80, 000 engineering hours is what it took. And that system is called Dyname 3.0.

THE PRINCIPLE

Mimicking how we as riders transmit power to the pedal and amplifying it. This is the basic premise upon which the Powerplay was developed.

Why?

Because Rocky Mountain doesn’t want an off-the-shelf system to be used in their bikes.

Why?

To use a Bosch, Shimano, Yamaha or any other off-the-shelf system, a compromise must be made. You have to rework linkages, pivots, suspension design and ultimately compromise handling.

That is not the Rocky Mountain way.

These guys don’t compromise handling on any of their bike platforms, just riding one reinforces that mentality. So they accepted the infinitely harder task of creating a custom drive unit from the ground up.

But how exactly is it different?

Simply, it’s far more intelligent at delivering power than any off-the-shelf system.

Now, not so simple. A sophisticated torque arm helps control the amount of power you put into the crank. More power input by you and there is more power output in the system. The power peaks at 770 Watts.

It’s also one of the most powerful (legal) E-MTBs too, with a maximum torque of 108Nm.

Compared to other systems, when you put pressure on the pedal the bike reaches close to peak power quickly. On an E-MTB, riding mountain bike trails that’s not what you want.

In other words, it only delivers as power as you need - then amplifies it. Imagine riding a normal mountain and getting the front wheel over a tree root or log; you quickly pedal-kick to lift the front wheel, you don’t apply all the power you have. Imagine when you’re climbing and cornering, you gently apply pressure at the pedals to keep your momentum going. In this scenario, too much power will cause you to understeer and lose control - usually into a tree.

BATTERY

For 2020, Rocky Mountain has increased the size of their e-bike batteries to 672Wh. This is one of the largest stand alone batteries we’ve seen, and much larger than Giant’s Trance E+ and Reign E+ series of electric bikes. This means, you’ll get a significant increase in battery usage and distance.

Rocky Mountain uses a Samsung battery on all their E-Bikes. There are no shortcuts here. They’ve chosen a brand with reputation and quality manufacturing.

THE FRAME

The Powerplay Altitude Alloy 50 uses (you guessed it) an aluminium frame. But it’s not just any aluminium, it’s the best damn aluminium you can use on a mountain bike.

On a serious note, keep in mind that Rocky Mountain is not a marketing brand. They are an engineering brand. The boffins at Rocky HQ spend years developing a platform and will only release it when it’s ready.

More importantly, the stuff I mentioned about ride quality before applies here. The Altitude Powerplay is designed within millimetres of the Altitude chassis that it was based off. This cannot be done with an off-the-shelf drive system.

It was the single most powerful motivating factor for Rocky.

And it was successful. Jumping from the Altitude Powerplay to the Altitude, there is no difference in the overall feel. The suspension kinematics feel the same and the handling on both is superb.

It’s also important to note that when Rocky set out with the Powerplay Project, any upgrades or enhancements that were developed had to be compatible with previous models.

This is in stark contrast to most other brands. They will eliminate the previous model and continue producing something completely different. As a customer purchasing a high-end product this is an important consideration.

TALK THE TORQUE

The Altitude Powerplay is one of the most (legal) E-MTBs in the market at 108Nm.

A lot of you researching E-Bikes might assume that the power delivered is instant. It’s not. For mountain biking, you need an instant response; pedalling just before a jump, pedal-kicking over obstacles, applying pressure on a tricky part of a climb.

Dyname 3.0 is close to instant power delivery, especially compared to other systems.

The torque is controlled via a sophisticated torque arm that measures your power input and chain tension (critical). And it measures this stuff 1,000 times a second.

What does this mean?

Amazing traction (especially in the wet) and the most natural-feeling power delivery (the aim of the whole project) out of any E-MTB.

Referring to the graph above. There is a huge delay between when the torque response of the Powerplay and off-the-shelf systems. This is the delay I was talking about above.

The difference between your power input and the torque response of the Powerplay (broken grey line and solid red line, respectively) both start at the same time. No other system does this.

The second graph above shows how quickly power comes off. As you can see (broken grey and solid red lines) both decelerate at the same time but the competition (off-the-shelf systems) are too slow; resulting in understeer. Remember the tree?

POWER

Power is no good if you can reach it. Most mountain bikers tend to pedal in the range of 70RPM to 80RPM. And this is where you access the Powerplay’s maximum power.

See how the power drops off quickly the faster you pedal (above 95RPM). That’s because pedalling at this speed over tree roots and rocks is almost impossible, and not very efficient.

POWERPLAY ALTITUDE ALLOY 50 BUILD KIT

The Altitude Alloy 50 specification consists of RockShox suspension, SRAM NX drivetrain, Maxxis tyres, Race Face components and Sun Duroc rims.

A RockShox Yari RC helps suspend the front of the Altitude. It features compression adjustment, rebound and air pressure - all the basic stuff.

Using the compression dial you can slowly turn the adjuster until it’s fully locked out. Rebound controls the speed of the suspension (after it’s absorbed an impact) - the return speed. Air pressure is based on body weight; more weight equals more air pressure.

It’s the same adjustments for the RockShox Deluxe RT rear shock too.

A new air spring called DebonAir is used in both front and rear suspension units. DebonAir is using a larger negative air volume in the air spring. This means in the first 30% of suspension movement, the fork and the rear shock feels super supple and smooth; delivering much better traction on small tree roots and rocks.
