One of the most captivating features of the G4i is its predictive electronic shifting, linked to torque sensors in the motor and bottom bracket. This system anticipates the rider’s gear needs based on their riding style and conditions, promising a smoother and more intuitive ride.

Integrated Dashboard and Lighting

The aluminum handlebars feature an integrated ‘dashboard’ with LEDs indicating battery level, speed, gear position, and daylight running light status. This dashboard, inspired by racecar technology, consolidates all necessary information in an easily accessible and visually appealing format.

Portability and Practical Weight

Effortless Folding Mechanics

The Gocycle G4i offers an impressively quick and simple folding process that’s mastered in under 25 seconds—though it does come with a slight learning curve. Activation involves a red aluminum button on the mid-frame and a similar mechanism at the base of the top-tube. This sequence allows the bars to be folded downward and the frame inward efficiently. Despite the rapid fold, caution is advised due to potential pinch points. Once compacted, the bike’s top-heavy nature requires some acclimatization for maneuvering, yet it remains sufficiently nimble for navigating through busy urban transit systems or fitting into the boot of a small hatchback, with the saddle aiding in its mobility.

Gocycle G4i Weight: Companion for the Urban Commuter

Weighing in at just 17.1kg (37.7 lbs) including pedals but excluding the kickstand, the Gocycle G4i stands out as a lightweight option in the folding e-bike market. This manageable weight enhances the bike’s portability, making it an ideal choice for commuters who may need to carry their bike up stairs, onto public transport, or load it into a car. The streamlined weight coupled with its compact folded dimensions provides a practical solution for those seeking a blend of performance and convenience without the bulk typically associated with electric bikes.

GocycleConnect App: Integrating Technology with Riding

Setup and Customization

Despite being a foldable model, the G4i showcases impressive stability that rivals and even exceeds many in its class, including some of the best hybrid bikes. With a wheelbase of 106.5cm, it’s a touch longer than a Brompton and demonstrates that foldable bikes need not sacrifice a smooth riding experience. This length provides a foundation for stable and responsive handling, alleviating the common ‘twitchiness’ associated with many folding bikes. The head angle is set at about 70 degrees, which is more relaxed than most road bikes and other folders, contributing to predictable and manageable steering dynamics. This geometry enables the G4i to handle urban environments adeptly, making quick work of dodging potholes and other common city road hazards.

Adjustability and Comfort

The G4i comes in one frame size but offers extensive adjustability to accommodate various rider heights, ranging from 5 feet to 6 feet 5 inches. The telescopic seatpost, adjustable with an allen key stored conveniently under the saddle, allows for significant vertical customization.
