Gocycle G4i Review

Oct 2021

Price: $4999.00 | Model Year: 2021 | The 4th generation Gocycle, one of the fanciest and lightest folding electric bikes available today! Improved half-folding design is much faster and cleaner than removing the wheels on prior model years. Updated motor offers more power with less noise. Available in three professional colors, premium optional accessories for improved utility.

Observations
  • The 4th generation Gocycle, one of the fanciest and lightest folding electric bikes available today! Improved half-folding design is much faster and cleaner than removing the wheels on prior model years. Updated motor offers more power with less noise. Available in three professional colors, premium optional accessories for improved utility.

  • Internally geared electronically actuated Shimano Nexus 3-speed hub provides predictive or manual shifting options with an intuitive half-grip twist shifter design. There's no derailleur hanging down that could get bumped during transport, and the chain is completely encased in the "clean drive" casing. You can shift gears at standstill, and the hydraulic disc brakes are consistent and easy to activate.

  • Proprietary front hub motor produces less noise, provides traction control, and still produces 500 watts of nominal power output. Multi-sensor pedal assist measures wheel speed, pedal cadence, and torque to provide a natural feel. A small trigger throttle, available in some geographies, supplements pedal assist to add power or give your legs a break. The bike still uses premium Panasonic batteries for maximum reliability and lifespan.

  • High visibility reflective tires and bright integrated headlight improve safety, optional rear rack and back-light maximizes your visual footprint. Unique handlebar-integrated LED display provide basic feedback about assist level and battery charge, but the optional smartphone apps provide much more insight. Surprisingly good comfort for a folding model thanks to high volume tires, ergonomic grips, comfortable saddle, and a rear shock absorber bumper.
