![]() However, there’s a clear connection between the Powerplay and ice hockey, at least semantically. The new Rocky Mountain Altitude Powerplay wants to shatter all preconceptions about Canadians, showing the world that Tim Hortons is nowhere near as popular in Canada as it might seem. The Altitude Powerplay features a conventional crankset and bottom bracket.Ī classic Canada stereotype: All Canadians play ice hockey and eat at Tim Hortons at least once a week. While the small upper jockey wheel applies the power to the chain, the lower pulley measures chain tension and thus serves as a torque sensor. Rocky Mountain’s latest motor, the Dyname 4.0, is smaller and lighter than its predecessor, but still delivers a solid performance. The motor itself, on the other hand, is particularly quiet and doesn’t rattle on rough terrain – which is the problem of many conventional mid-drive motors. The drawback? As its predecessor, the noise of the chain, which runs over several cogwheels, is significantly louder than most direct competitors. The position of the motor, for example, allows for shorter chainstays and gives bike designers more freedom in developing the rear triangle. This unconventional motor concept has several advantages but also some disadvantages. Despite using a mid-drive motor, the Altitude Powerplay employs a conventional crankset and press-fit bottom bracket. This senses how strong you’re pedalling and thus how much tension you’re putting on the chain and sends the data directly to the motor system. Moreover, the Dyname 4.0 motor doesn’t transfer its power to the cranks and chainring, but directly to the chain via a small jockey wheel, while an additional pulley wheel serves as a torque sensor. Unlike conventional mid-drive motors, the Dyname 4.0 is integrated into the front frame triangle just above the bottom bracket and not just bolted to the bottom of it. According to the Canadian manufacturer, the fourth-generation of the Dyname motor is much smaller and about 750 g lighter than its predecessor. Instead of using the motors of established third-party manufacturers like Bosch or Shimano, the Canadian team has developed their own motor system in conjunction with Propulsion Powercycle. The new Dyname 4.0 motor is the next evolutionary step up from Rocky Mountain’s unique motor concept. The new Dyname 4.0 motor of the Rocky Mountain Altitude Powerplay Carbon 70 Read our first ride review to find out how it fared on the trail. We had the exclusive opportunity to take the € 8,800 and 24.5 kg Rocky Mountain Altitude Powerplay C70 for a quick spin even before its official release. According to Rocky Mountain, the Instinct is in its element on epic adventures and explorative tours. The Instinct also rolls on big 29” wheels but has slightly less travel than the Altitude, offering 150/140 mm travel, at the front and rear respectively. The Altitude Powerplay, which rolls on 29” wheels and relies on 170 mm travel at the front and 160 mm at the rear, is aimed at fast, aggressive riders and demanding trails. ![]() While the two bikes share several frame features, they were developed for different fields of application. The new frame platforms of the Altitude Powerplay and Instinct Powerplay are built around the successor of the Dyname 3.0 motor, the brand-new Dyname 4.0. The updated 2022 models still rely on the brand’s own motor and battery system, which has also been revised from the ground up for the upcoming season. First off, congratulations to Rocky Mountain, who just turned 40 last September and have actively helped shape the future of mountain biking from the get go! Four years ago, the Canadian cult brand jumped on the eMTB wagon, introducing two very original and striking eMTB models, the Instinct and Altitude, which are both built around Rocky Mountain’s proprietary Powerplay motor.
