Design and Build Quality
The Cube Stereo Hybrid 120 Pro 625 showcases a thoughtful design and high build quality, making it a versatile electric mountain bike. Let’s delve into the key features, starting with the suspension system. The RockShox Recon fork provides 130mm of travel, offering a responsive and controlled ride. The air fork is not only lighter but also provides more adjustability, allowing riders to fine-tune their preferences. The black anodized stanchions add a touch of style, and the compression adjuster with a progressive clicker allows riders to lock out the suspension when needed.
The Boost Hub spacing with a 15mm through axle enhances the bike’s strength and stiffness, providing a sturdier bracing angle. The choice of black spokes and rims with reinforcement eyelets indicates a focus on durability and longevity. These eyelets reduce the risk of damage during truing or tightening, showcasing attention to detail in the build.
The Smart Sam tires, with a size of 29×2.6 inches, feature active lines for puncture protection. The use of plus-size tires (2.6 inches) is notable, providing increased volume, float, and stability. This design choice enhances the bike’s ability to navigate rocky terrain efficiently while maintaining a low attack angle for speed.
One distinctive feature is the combination of mountain bike features, such as knobby tires and full suspension, with the addition of plastic fenders. While these fenders contribute to the “Allroad” concept, it’s mentioned that they may produce some rattling, especially on rough terrain. The inclusion of a tool-free adjustable kickstand is appreciated, especially for the convenience of parking an electric bike without the risk of damage.
The frame, available in four sizes, showcases Cube’s commitment to providing options for a wide range of riders. The metallic green color with black accents and a hint of orange adds a stylish touch to the overall design.
Integrated lights, with a focusable headlight positioned on the crown, contribute to rider visibility. The rear light, with a 25 kg weight rating for the rear rack, offers practical utility for commuting or errands. The design of the rack interface is well-integrated, avoiding protrusions and potential snag points.
The saddle is noted for its comfort, and the sequence 30.9mm seat post, though not a dropper post, suits the bike’s full-suspension setup. The absence of a dropper post might limit the bike’s performance on rough terrains where quick adjustments to saddle height are desired.
The Shimano hydraulic disc brakes with adjustable reach levers provide reliable stopping power. The quad-piston calipers and extra-large 203mm rotors, both front and rear, cater to the demands of the bike’s 29-inch plus-size tires. The boost hub spacing with a 12mm through axle adds to the bike’s stability.
The bike’s weight is disclosed at approximately 60 lbs, with potential variations based on the chosen frame size. The suspension lacks compression or lockout on the rear, and the kickstand, while appreciated for its utility, is noted for causing some bouncing during rides.
In terms of ergonomics, the bike features semi-ergonomic grips, a short stem for a more upright riding position, and a wide handlebar reminiscent of mountain bikes. The internal cable routing through the headset and oversteer protection are highlighted for their clean aesthetic and functional benefits.
The battery, easily accessible through a rubberized shield, utilizes the Abus key system for security. While the key system provides flexibility for matching with frame locks or cafe locks, the lack of a locking mechanism for the battery cover is mentioned as a potential vulnerability.
Once charged, the operation of the bike is straightforward, with the LED remote offering a clear display of assist levels using different colors. However, the absence of an additional LCD display is noted, limiting feedback on speed, range, and other ride metrics. The LED remote’s USBC port is mentioned, but disappointingly, it is designated for diagnostics only and not usable for charging external devices like a smartphone.
The clean and organized cockpit with Shimano Deore trigger shifters is praised, providing a clutter-free and user-friendly interface. The potential for integrating the Kiox 300 display for on-screen directions adds another layer of functionality, depending on the rider’s preferences.
So, the Cube Stereo Hybrid 120 Pro 625 impresses with its well-thought-out design, robust build quality, and attention to detail in components and features. It caters to riders seeking a versatile electric mountain bike for a range of terrains and riding styles.
CUBE Stereo Hybrid 120 Pro 625: Motor and Driving Test
The Cube Stereo Hybrid 120 Pro 625 is equipped with the powerful Bosch Performance Line CX motor, providing an impressive 85 Nm of torque. This motor is known for its advanced features, including the ability to measure rear wheel speed, pedal cadence, and pedal torque over a thousand times per second. The result is a responsive and dynamic electric assistance that adapts to the rider’s input seamlessly.
One notable feature of the Bosch motor is its shift detection, which, while not perfect, adds a layer of sophistication to the riding experience. Paired with the 12-speed drivetrain, this motor ensures smooth transitions through gears, making it particularly valuable for riders engaged in trekking or bike packing. The robust torque output of the motor is a boon, providing substantial power without compromising the integrity of the chain or cassette teeth.
The motor supports pedal cadence above 120 RPM, allowing riders to maintain assistance even in low gears and high-speed scenarios. This feature eliminates the previous issue where motors might struggle to keep up with rapid pedaling in challenging terrain.
Bosch’s commitment to innovation is evident in the magnesium housing, part of their Smart System Technology. The integration of the latest app and a reliable 4-amp charger further enhances the overall user experience. The batteries, although not elaborated on in the provided information, are mentioned as being of high quality.
Moving on to the drivetrain, the Shimano Deore 12-speed system with a clutch mechanism ensures precise and stable shifting. The inclusion of a 38-tooth chainring with a plastic bash guard is highlighted, with a note on the perceived drawback of plastic versus aluminum alloy. The absence of a narrow-wide tooth profile is mentioned as surprising, considering it’s a feature found on some other Cube bikes.
So, the Cube Stereo Hybrid 120 Pro 625 impresses with its powerful Bosch motor, advanced features, and thoughtful design elements. The bike is well-suited for various riding styles, although some component choices, such as the plastic chainring bash guard, may leave room for improvement.
Application
The Bosch ebike Flow app, on the other hand, receives positive feedback for its versatility. It allows users to customize assist levels, top speed, and power delivery, offering a high degree of personalization.
The automatic and eMTB modes are highlighted as convenient options for riders who prefer a more hands-off approach to adjusting settings. The app also includes features like geofencing and GPS-based directions, contributing to a comprehensive ecosystem for riders.
Battery and Range
Navigating the intricacies of the Cube Stereo Hybrid 120 Pro 625’s battery and user interface reveals both thoughtful design elements and potential areas for improvement. The 625 Wh battery, while providing ample capacity for extended rides, presents some challenges during removal and reattachment.
The process of detaching the battery is described as somewhat precarious, with the need to align it carefully and ensure the key is twisted for proper locking. This two-handed operation might be a bit cumbersome, and the reviewer notes the potential for fumbling with the keys during this process.
The placement of the charging port on the side of the bike, especially with the fender in close proximity, is mentioned as less than ideal. It requires bending down and reaching towards the crank arm, risking contact that could potentially damage the charging port. The suggestion to have the charging port higher up on the frame for easier accessibility is a valid point.
CUBE Stereo Hybrid 120 Pro 625: Conclusions
Overall, the Cube Stereo Hybrid 120 Pro 625 stands out for its powerful Bosch motor, high-capacity battery, and thoughtful design elements.
However, some minor inconveniences during battery handling and charging port placement, as well as limitations in the LED remote’s functionality, are areas that could be addressed for an even more user-friendly experience.Â
The comprehensive Bosch app and potential integration with additional displays showcase the brand’s commitment to offering a versatile and customizable riding experience.
