Electronic shifting - How it Works

G3C_Black__7_.jpg

The shifting on a G4i+, G4i, GXi, G3, G3C, is controlled with the right hand twist switch.

 

  • You can shift the gears any time using the right-hand twist switch. To shift up a gear, rotate the twist shifter towards you (wrist down) and release.
  • To shift into a lower gear, rotate the twist shifter away from you (wrist up) and release.
  • Your current gear selection can be seen as the 3 LEDs in the middle of handlebar dashboard.
  • The Gocycle has downshift protection - if travelling too fast the Gocycle will not shift into a lower gear. If this happens, you will see the gear LEDs blinking.
  • Gocycles with electronic shifting come as standard with Predictive Shifting enabled.

 

Electronic Shifting Tips

  • The Gocycle electronic predictive shifting will automatically change gear depending on your speed.
  • The Gocycle will only shift gear when you stop pedalling - it will not shift gear automatically when you won't expect it.
  • When increasing your speed, temporarily stop pedalling to allow the Gocycle to change gear, then continue pedalling. You can also shift up manually as described above.
  • When decreasing speed or at a stop, you will stop pedalling naturally, and the Gocycle will automatically change down gears.
  • You can use the shifter as normal to manually shift even when predictive shifting is on

 

Disabling and enabling Predictive Shifting (on/off)

 

Gocycle G4i and G4i+

Connect to the Gocycle, and press "⋮" on the top right of the Gocycle card and switch 'Predictive shifting' either 'ON' or 'OFF'. 

 

Gocycle GXi, G3+, G3C, G2

  1. Hold both twist switches* down for 15s 
  2. Use the right twist switch* to scroll through until 17 LEDs are illuminated for Mode 17. 
  3. Hold the left switch* down until the 17 LEDs flash 
  4. Use the right switch* to toggle between '+' for predictive shifting on and '-' for predictive shifting off. 
  5. When on the predictive shifting option you would like on the dash hold the left twist switch* to confirm the selection and return to your riding mode. 

*For Gocycle G2, press and hold the red and black buttons

 

Adjusting the electronic shifting

If you notice that there is clicking or the gears aren't shifting correctly, the servo that changes the gear might nee to be adjusted. See the guides bellow for your model. 

 

Adjusting the Shifting (Servo Calibration) - G4i and G4i+

Adjusting the Shifting (Servo Calibration) - G2, G3, G3C, G3+ and GXi

 

Adjusting the Shifting (Servo Calibration) - G4i and G4i+

  1. Turn on the Gocycle 
  2. Connect to the Gocycle in the GocycleConnect app. You may need Set up the GocycleConnect app
  3. Go to
    1. Settings
    2. Diagnostics > Go
    3. Servo Calibration > Start 
  4. Gently hold the rear brake and pedal forwards on the crank arm.
  5. Keep the pressure on the crank arm and the wheel speed constant during calibration.
  6. You will hear some adjustments being made to the servo. This is normal
  7. Keep pedalling until you hear a confirmation beep which is same as Gocycle startup *. 

*If failed there will be 6 beeps (de do de do de do)

 

Adjusting the Shifting (Servo Calibration) - G2, G3, G3C, G3+ and GXi

The Gocycle G2, G3, G3 Carbon, G3+ and GXi have electronic shifting, which is actuated by a servo unit inside the Cleandrive®. Shifting is calibrated during production but it can be re-calibrated manually. See the video below which details how to adjust the trim of each gear:

 

 

Low Battery and Gocycle Electronic Shifting

If the battery of the Gocycle is low on charge the motor may cease to operate to help protect the battery.

The electronic shifting will continue to work for 2-3 hours once the motor ceases to operate. 

If the Gocycle continues to be used, the battery may enter a critically low state and switch off to prevent any permanent damage. In this case the electronic shifting will not be available.

Once the Gocycle is in a low battery state it is important to charge the Gocycle as soon as possible.
