CUBE AMS Hybrid 177

Depending on the equipment variant, the Cube AMS Hybrid One77 is powered by either a Bosch Performance Line CX or a Bosch Performance Line CX-R. Both drives belong to the full-power class. The difference compared to a classic light e-MTB therefore lies less in the motor power and more in the ratio of power, battery, and total weight. The AMS combines a powerful drive with a lighter chassis and a more compact energy storage system.

The Bosch Performance Line CX delivers up to 85 Nm of torque in the configurations considered here. This is sufficient for steep forest paths, technical ramps, and repeated climbs in trail areas. The motor responds in a controlled manner and is easy to modulate, even on slippery surfaces. For most riders, this version is the more sensible choice if balanced power delivery is more important than a particularly aggressive race mode.

The Bosch Performance Line CX-R provides up to 100 Nm and is tuned more for athletic use. Its assistance kicks in more directly and remains active briefly after the pedal impulse. On technical uphills, this overrun helps to clear steps, roots, or tight switchbacks when the pedals must be briefly unweighted before an obstacle. However, this requires clean handling of the brakes, gear selection, and assistance level. On loose ground, the additional power can cause the rear wheel to spin more easily.

If you primarily ride natural trails and are looking for easily controllable response, the Performance Line CX is generally sufficient. If technical uphills, fast self-powered shuttle laps, or the most direct race feel possible are your priorities, the Bosch Performance Line CX-R is a better fit. The stronger motor does not automatically make the bike faster, but it can provide more reserves on difficult sections.

The 600 Wh battery is firmly integrated into the down tube. It cannot be removed for daily charging. Therefore, the charger must be connected directly to the parked bicycle. Those who store their e-MTB in a garage or bike room with a power outlet will hardly be inconvenienced by this. However, if the bike is kept in a basement while charging is only possible in the apartment, the non-removable battery is an important factor to consider before purchasing.

The fixed integration saves on components needed for a large removal opening and allows for a slimmer down tube. This benefits the weight, frame stiffness, and compact appearance. The disadvantage remains the limited convenience for charging and future battery servicing. The energy storage unit is technically replaceable, but removal is intended to be a workshop task.

For longer tours, the frame is prepared for the Bosch PowerMore 250. The range extender sits in the area of the bottle cage mount and increases the total capacity to 850 Wh. The additional weight is only carried when the route requires it. For short trail rides, the bike remains lighter, while more energy reserves are available on extended tours. The actual range depends on elevation gain, rider weight, temperature, surface, tire pressure, and assist level. A blanket mileage figure would therefore be of little significance for an e-enduro.

The TM is the pragmatic choice for riders who want to take advantage of the carbon frame and lightweight design concept without paying the premium for extra-light or highly adjustable components. Its specifications are designed for demanding trails. For frequent days in the bike park or at very high speeds, however, more finely tunable suspension and higher-performance wheels can still make a noticeable difference.

The Action Team model hits the most sensible middle ground for many athletic riders. The Bosch Performance Line CX-R suits the performance-oriented character of the frame. At the same time, a larger portion of the budget is invested in components that can be felt directly on the trail. These include more precise suspension, powerful brakes, and a higher-quality drivetrain. Those who use the bike regularly on technical routes will find a setup here that usually requires no immediate modifications.

The Super TM is aimed at riders who want to start at the highest possible level in terms of suspension, drivetrain, and components. The additional cost pays off primarily at high speeds, on long descents, and during frequent bike park use. Lighter components can improve handling, while more sophisticated suspension offers more options for adjusting compression, rebound, and spring characteristics. For occasional tours and moderate trails, this level of equipment is not strictly necessary.

When choosing, the motor should not be the only criterion. A well-tuned suspension and powerful brakes often influence control downhill more significantly than additional torque. If you want to limit your budget and upgrade individual parts later, the TM is a good option. If you are looking for balanced, complete equipment without the immediate need for modifications, the Action Team is particularly interesting. The Super TM is suitable for riders who will actually make use of the premium for high-quality components on demanding trails.

The specific specifications can vary depending on the model year and available version. It is therefore worth taking a look at the respective product configuration before making a decision. The exact fork, shock, braking system, wheels, and the installed motor version are particularly relevant.

The Cube AMS Hybrid One77 and the Stereo Hybrid One77 cover a similar suspension travel range but follow different priorities. The AMS is the lighter e-enduro, more strongly focused on dynamic trail riding. The Stereo places more emphasis on range, everyday practicality, and a calmer ride.

The most striking difference is the weight. Depending on the configuration, the AMS stays under 22 kilograms. A Stereo Hybrid One77 can weigh around 25 kilograms, depending on the frame and components. A three-kilogram difference is easily overlooked on a data sheet, but it is clearly noticeable on the trail. The lighter bike is easier to pull over obstacles, quicker to flick around, and easier to correct if you miss your line.

The model lines also pursue different approaches with the battery. The AMS uses a non-removable 600 Wh battery. This saves weight but requires a charging spot with a power outlet. With the Stereo, the focus is on larger, removable battery concepts. This is practical for long tours and makes charging in an apartment easier. However, the total weight increases as a result.

The rear suspension characteristics also distinguish the models from one another. The AMS works more progressively. At the beginning of the travel, the rear end reacts sensitively, but builds up more support towards the end. As a result, the bike uses its travel comfortably for small bumps without bottoming out too quickly on hard landings or deep compressions. This behavior suits jumps, steep drops, and an active riding style.

The Stereo tends to have a more linear suspension setup. It uses its travel more consistently and provides a composed ride on long, rough descents. Riders who prefer to stay centered on the bike and favor predictable suspension travel can benefit from this. The higher weight contributes to a more planted feel, but requires more physical effort in tight corners and during quick direction changes.

If you frequently go on long rides with high mileage, prefer to remove the battery for charging, and favor a calm ride, the Stereo Hybrid One77 is the better choice. If technical trails, jumps, and a nimble E-Enduro are your priorities, the AMS Hybrid One77 is more compelling. The weight advantage is particularly interesting for riders coming from a non-motorized enduro bike who want to maintain that agile handling as much as possible.

For pure bike park days, both concepts work well. The AMS can be ridden more actively and is easier to get airborne. The Stereo remains more composed at high speeds and offers plenty of stability thanks to its higher weight. Anyone who frequently has to load the bike, carry it up stairs, or transport it on a rear rack will, in turn, benefit from the lower weight of the AMS.

The Cube AMS Hybrid One77 doesn't ride like a non-motorized enduro bike, but it comes closer to that feeling than many heavy full-power e-MTBs. The motor and battery add weight to the area around the down tube and bottom bracket, which makes the bike feel well-planted on the trail. At the same time, it remains light enough to actively lift the front wheel and change lines in tight corners.

The mullet setup combines a 29-inch front wheel with a 27.5-inch rear wheel. The large front wheel rolls more easily over roots, rocks, and braking bumps. It offers a large contact patch and contributes to stability. The smaller rear wheel shortens the rear end of the bike, creates more room to move, and supports quick changes in direction. It also leaves more space between the tire and your body on steep descents.

This combination suits an e-enduro that aims to be both stable and agile. In open, fast sections, the 29-inch front wheel guides you securely through rough terrain. In tight switchbacks, the more compact rear wheel is easier to reposition. Those who have only ridden 29-inch enduros may initially perceive the rear end as livelier. After a short adjustment period, this character can be intentionally used for tight lines.

The progressive rear suspension offers noticeable support in the mid-stroke. The bike doesn't sag unnecessarily deep in berms and compressions. As a result, the geometry remains more stable, and the bike can be pushed over rollers or jumps. The resistance increases towards the end of the travel. This provides reserves for hard impacts, but does not replace a correct shock setup.

The new connecting bridge in the rear triangle increases lateral stiffness. Compared to older Cube models, the bridge offers a significant advantage in stiffness, resulting in less torsion in the rear end. Under high loads, the two sides of the rear triangle move in a more controlled manner relative to each other.

This is particularly noticeable in hard berms, on angled landings, and through fast rocky sections. The rear wheel tracks the chosen line more precisely instead of feeling vague. Too much stiffness can make a bike feel nervous, but the suspension and tires still handle a portion of the damping.

Compared to an enduro bike without a motor, the AMS requires a bit more attention when braking. The additional system weight generates more momentum and places greater strain on the brakes and tires. In return, the low center of gravity stabilizes the bike in fast corners. On flat, twisty trails, a traditional enduro bike remains lighter and more direct. As soon as the route heads uphill or multiple descents are planned for the day, the motor significantly shifts the range of use.

On technical uphills, the powerful Bosch drive system shows its advantages. The short rear end makes tight switchbacks easier, while the large front wheel rolls over steps well. A central body position is crucial. Too much pressure on the handlebars reduces traction on the rear wheel. A position shifted too far back can cause the front wheel to lift on steep ramps. With the right gear and consistent pedal pressure, the motor's power can be used in a controlled manner.

The Cube AMS Hybrid One77 is generally suitable for the bike park. Cube classifies the model in Category 4. This category includes challenging terrain, higher speeds, and jumps within the limits set by the manufacturer. The 170 millimeters of travel and the descent-oriented geometry are well-suited for this use. After frequent days in the park, bearings, spoke tension, tires, brake pads, and suspension should be checked regularly.

The chassis is made of Cube's C:62 carbon and is manufactured using the Advanced Twin Mold process. Cube controls the shaping of the carbon layers during curing to reduce excess resin and unnecessary material. The result is a lightweight frame designed to handle the stresses of an e-enduro.

• The C:62 carbon frame contributes to a total weight of less than 22 kilograms.
• Internal cable routing guides cables and hoses through the headset into the frame.
• The UDH derailleur hanger simplifies spare parts supply and is compatible with modern shifting systems.
• A rear triangle bridge increases lateral stiffness during cornering and hard landings.
• The headset allows for an angle adjustment of 0.6 degrees.
• The frame is prepared for the Bosch PowerMore 250 range extender.

The angle adjustment in the headset changes the head tube angle without requiring a different frame or a new suspension fork. In the slacker position, the bike runs more stably at high speeds. The front wheel is positioned further ahead of the rider, which can provide more confidence on steep descents. The steeper setting makes the steering more direct and is better suited for tight trails with many slow corners.

A change of 0.6 degrees sounds minor, but is noticeable on the trail. Riders do not need to constantly change the position. It makes more sense to choose the preferred setting based on terrain and riding style, and then adjust the suspension, cockpit, and tire pressure accordingly. The slack position is generally well-suited for bike park tracks and fast enduro trails. The steeper setting is ideal for twisty low mountain trails and tours with many technical uphills.

Internal cable routing ensures a tidy cockpit, but makes certain maintenance tasks more difficult. Replacing brake lines or cables can take more time than with externally routed cables. The UDH derailleur hanger, on the other hand, is a practical advantage. It follows a widespread standard and is easier to replace in the event of a defect than a rare, model-specific derailleur hanger.
