The Z7 Hybrid's Potential
Z7 Hybrid: A Mixed Bag of Innovation
The Z7 Hybrid presents a compelling proposition for eco-conscious drivers, but its implementation reveals several shortcomings.
Gearbox & Handling
The Z7's gearbox is notorious for its clunky shifting, especially during acceleration and deceleration. This leads to a jerky ride and compromises the overall driving experience. Additionally, the vehicle's handling feels heavy and unresponsive, particularly in tight corners and at higher speeds.
Price & Competition
The Z7's hefty price tag underscores its status as a premium offering. However, this premium price is a significant drawback when considering the lackluster performance compared to its petrol-powered rivals. These competitors often achieve better fuel efficiency and offer a more refined driving experience for a lower cost.
Practicality & Key Takeaways
While the Z7 Hybrid offers a solid attempt at integrating hybrid technology, it falls short in delivering a truly competitive package. Its shortcomings in terms of gearbox responsiveness, handling, and cost-effectiveness make it hard to recommend for mainstream adoption.
-
Key Takeaways:
- The Z7 Hybrid prioritizes hybrid technology over overall driving experience.
- It may appeal to early adopters, but its lack of practicality hinders mass appeal.
- The high price point, combined with drawbacks in performance, make it a tough sell against established petrol alternatives.
Ride Quality and Brakes: 3/5
Z7 Hybrid: Handling and Ride Comfort
The Z7 Hybrid's innovative design, featuring an electric motor and battery surrounding the petrol engine, comes with some trade-offs in handling and ride quality.
Handling Characteristics
* Top-Heavy Feel: The placement of the heavy electric motor and battery high in the chassis contributes to a top-heavy feel, particularly at slower speeds. This can make the bike feel unstable during tight turns or maneuvers.
* Tight Turning Circle: The long wheelbase, designed to accommodate the battery pack, results in a tighter turning circle compared to conventional bikes. This may make navigating narrow spaces or tight corners more challenging.
Suspension and Ride Comfort
- Harsh Suspension: Despite good brake and fork components, the Z7 Hybrid's shock absorber is relatively stiff and struggles to absorb bumps effectively. This results in a less comfortable ride, especially on rough roads.
Key Takeaways
* Trade-offs: The Z7 Hybrid's design prioritizes electric power and range but compromises some handling characteristics and ride comfort.
* Practical Implications: Riders should be aware of the bike's top-heavy feel and tight turning circle when navigating challenging terrain or urban environments.
* Consider Alternatives: If ride comfort and handling are paramount, riders may consider traditional petrol-powered bikes or hybrid models designed with more balanced weight distribution and suspension systems.

Z7 Hybrid: A Blend of Performance and Efficiency
The Z7 Hybrid offers three distinct driving modes: Sport-Hybrid, Eco-Hybrid, and fully-electric EV. Each mode caters to different driving preferences and prioritizes either performance, efficiency, or pure electric range.
Sport-Hybrid Mode
- Manual Gear Shifting: This mode allows drivers to control gear changes using bar-mounted buttons. This unconventional setup may feel odd for drivers accustomed to automatic transmissions, especially considering the automatic shifting option in Eco-Hybrid mode.
- Engine Response and E-Boost: The engine boasts a responsive throttle and benefits from an e-boost function that provides a temporary boost of power. This feature is particularly helpful for overtaking maneuvers, providing an extra surge of acceleration.
- Gearbox Quirks: While the e-boost is a welcome addition, the gearbox can be a source of frustration. Gear changes are noticeable and can result in a lurching sensation, especially when maintaining consistent throttle.
Eco-Hybrid Mode
- Automatic Gear Shifting: This mode features automatic gear changes, offering a more relaxed driving experience. The transmission seamlessly selects the optimal gear for fuel efficiency, optimizing power delivery for a smooth and comfortable ride.
- Fuel Economy Focus: The Eco-Hybrid mode prioritizes fuel efficiency, utilizing the electric motor to assist the gasoline engine during acceleration and deceleration. This helps to reduce fuel consumption and emissions.
Fully-Electric EV Mode
- Zero-Emission Driving: The fully-electric EV mode allows for completely emission-free driving, relying solely on the electric motor for power. This mode is ideal for short commutes or city driving, where range is less of a concern.
- Electric Range: The specific electric range will vary depending on factors such as battery capacity, driving style, and environmental conditions.
Key Takeaways:
- The Z7 Hybrid offers a versatile driving experience with three distinct modes.
- The Sport-Hybrid mode prioritizes performance and features an e-boost function, but the manual gear shifting and gearbox quirks can be a drawback.
- Eco-Hybrid mode focuses on efficiency with automatic gear changes and fuel-saving technologies.
- The fully-electric EV mode offers zero-emission driving for short commutes or city driving.
- The optimal driving mode depends on individual needs and preferences.

Equipment: 3/5
Underwhelming Equipment for the Price
Despite its hefty £12,000 price tag, the Z7 Hybrid's equipment list falls short of expectations for a premium motorcycle.
Key Missing Features
- Adjustable Forks: The standard forks lack adjustability for preload, rebound, or compression damping. This limits rider customization and fine-tuning for different riding conditions.
- Angle-Responsive Electronic Aids: The Z7 Hybrid lacks sophisticated electronics like cornering ABS or lean-sensitive traction control, which are common on competing models. This can compromise safety and performance in challenging riding scenarios.
- Traction Control: The absence of traction control means riders must rely solely on their skills to manage tire slip, potentially leading to reduced stability and control, especially in slippery conditions.
Dash and Connectivity
The bike includes a standard TFT dash with connectivity, but the Rideology app and dash interface lack the sophistication found in some competitors.
- Limited Rideology App Features: The app lacks features like turn-by-turn navigation, route planning, and advanced data logging capabilities, which are common in modern motorcycle apps.
- Basic Dash Interface: While the TFT dash provides essential information, its graphics and functionality are not as intuitive or advanced as some rivals, which offer more customizable layouts and rider aids.
Practical Implications
These omissions mean the Z7 Hybrid feels less premium and misses out on features that enhance safety, performance, and user experience.
Comparison with Competitors
Many competitors in the £12,000 price range offer adjustable suspension, advanced electronics, and comprehensive connectivity features. This makes the Z7 Hybrid's equipment feel underwhelming compared to its rivals.
