12 reasons not to buy

The Gocycle G4 is expensive.
Experts and owners feel the bike is slightly under-geared and wish for another high gear.
The G4 doesn't have a display. Riders must use their phone with the Gocycle app for ride data or to switch between pedal assist modes.
Several owners report Bluetooth pairing failures, and Gocycle says the app isn't supported by all devices.
The included phone 'mount' is just two elastic bands.
The G4's 292Wh battery is below average, especially at this price point.
According to testers and owners, the tires are prone to punctures.
The bespoke build and components make repairs and finding replacement parts more complicated.
The frame design limits options for locking the bike.
One reviewer complains that the internal hub occasionally skips gears.
The G4's maximum recommended payload capacity of 220lb is low. Exceeding 250lb voids all warranties.
A few buyers report electronic failures, requiring them to return the bike to Gocycle.

Bottom line

The Gocycle G4 is a folding e-bike with a 500W front hub motor and 292Wh battery. Testers praise the sleek design, power, quiet motor, brakes, and comfort. Its low weight, easy folding, and rapid charging make it a practical commuter. The G4 is slightly under-geared and prone to punctures, but its major issue is the lack of a display. Riders must use their phone to switch PAS mode or view ride data, but Bluetooth pairing can be problematic, device compatibility isn't ubiquitous, and the 'mount' comprises two flimsy elastic bands. Some owners even encounter electronic failures. Reviews are generally positive, but potential buyers should carefully consider these drawbacks, given the high price.
