Rocky Mountain overhauled their Powerplay and Dyname training systems and rebuilt their two e-bike options, the Altitude and Instinct Powerplays. Both new bikes will use the updated Dyname 4.0 drive system, which is now lighter and quieter.
The Dyname 4.0 motor is over 18% lighter than the previous version, and Rocky Mountain claims the motor has larger bearings for improved durability. The Dyname 4.0 also now has “a lower engine speed which reduces the amount of electric whine compared to other systems” and the 3.0 system’s top chain slider has been removed to reduce drag and noise. The motor has the same torque, at 108 Nm, and the same power at 700 W of maximum power.
Rocky Mountain reports that the torque curve has been redesigned to gradually apply power to achieve maximum power of 700W at maximum output of 700W, giving it a variable power curve. âBy having a variable power curve, you will have more control over your bike on the track, including scenarios such as steep and technical hill starts,â the brand explains in a press release.
Rocky has increased the capacity of the Powerplay battery from 672Wh to 720Wh for a larger charge, and the batteries are more easily removable. The bike is also compatible with an additional, compressible 314 Wh battery, for a total of 1,034 Wh.
There is a 4 amp charger and a 2 amp charger for newer models. The 2 amp charger will recharge a battery to 100% in just over seven and a half hours, while the 4 amp charger will cut the time by almost half. The new e-bikes also feature a larger screen called the Jumbotron, showing information such as cadence, average speed, and distance.
The Altitude Powerplay and Instinct Powerplay are similar, but the travel matches their non-motorized models, the Altitude having 160mm rear travel with a 170mm fork and the Instinct with 140mm rear travel and a 150 mm fork. Thus, they are intended either for enduro, all-mountain, or trail. Both bikes are available in sizes S-XL.
The bikes both feature 10mm base tuning, Ride-4 geometry tuning chip, internal cable routing, and a modular shock mount, only available on carbon models, which allows future updates to the kinematics. The aesthetics of the frame have also been updated for a more elegant look.
The Altitude geometry on an average bike in neutral setting has 64 Â° HTA, 76 Â° STA, 420mm seat tube length, 437mm chainstays, and 455mm reach.
The same size and tuning Instinct has 64.7 Â° HTA, 76.7 Â° STA, 420mm seat tube length, 437mm chainstays, 463mm reach and a wheelbase of 1,225 mm.
Rocky Mountain makes the Powerplays out of two frame materials, as they do with their non-motorized bikes, and a base model Instinct alloy bike will start at $ 5,600 while a Carbon 90 version will top out at $ 12,039.
The Altitude A30 comes with a coil damper and starts at $ 5,749 while the Altitude C90 stops at $ 10,649. For more information, see the Rocky Mountain website.
First impressions: Altitude Powerplay C70
I only managed to do one round on the new Altitude Powerplay, so I’ll keep it brief and save the full opinions for the next review. So far I am pleasantly surprised and satisfied with the new bike. I haven’t raced previous Powerplay models, but the engine in this version is sophisticated.
Rather than any sort of high speed whine, the motor has a quieter snore at this it is barely noticeable, although the sound becomes more noticeable after switching the power mode. The power delivery feels good and seems to match the driver’s input. Want more engine? Pedal harder. Less engine? Let go a bit.
I didn’t have a full charge on this bike prior to my ride, so I’ll be recording the charge and range details for the full review as well.
The Altitude Powerplay follows the steps of Rocky’s non-motorized Altitude and transforms into 29-inch wheels. The geometry of the Powerplay was in need of an update and in that regard it is quite similar to the Altitude I rode last year. The climb feels straight and supported, and the bike feels planted and eager to descend. Leave your questions in the comments, and I’ll do my best to answer them as I’ll ride this bike more. We will do a full review in the coming months.
