Preassembly Tips and Advice

  • If you are uncomfortable with bike mechanics, we recommend having your bike assembled by a bike shop or qualified bike mechanic.
  • Remove only the packing zip ties, taking care not to cut any wires, cables, or zip ties used to route wires.
  • Avoid touching the brake rotors with your fingers. Natural oils from your hands can contaminate the rotors, reduce braking performance, and cause a loud whining sound when braking.
  • Apply grease to the seat post before installation.


Assembly Basics


Cable Routing

Before installing your handlebar stem, inspect the wire and cable routing and match the orientation shown in the assembly video. The wires should not cross over, as incorrect routing can damage the electrical components of your bike.


Handlebars & Stem

You will need to install the stem and handlebars before riding.

  • Tighten the stem bolt to 5 Nm, then check that the front wheel is properly aligned.
  • Once the wheel is aligned, fully tighten the stem bolt to 7 Nm.
  • Using the 5 mm hex wrench, alternate tightening the two headset bolts until both are equally tight.
  • Confirm there is no play in the fork.


Brake Levers

The brake levers should face forward and be angled slightly toward the ground. This position allows you to comfortably operate the brakes while maintaining a secure grip and good control of the handlebars.

The lever position can be adjusted later to suit your personal preference.


Changing Class Settings

The Portola 02 arrives out of the box in Class 2.

To change the class setting, hold the DOWN and POWER buttons simultaneously for 2 seconds. You can then cycle through the available class settings:

  • Class 1 (C1): Top speed of 20 mph with pedal assist only. The throttle is inactive in this class.
  • Class 2 (C2): Top speed of 20 mph with both pedal assist and throttle.
  • Class 3 (C3): Top speed of 28 mph with pedal assist and 20 mph with throttle.


Post-Assembly Tuning and Safety Check

After assembly, complete the following checks before riding.



Common Assembly Issues

Minor transit damage can happen during shipping. Here are some of the most common issues and how to address them.

  •   Index your derailleur and verify the hanger is straight  
    Failure to properly index the derailleur and set the limit screws may cause damage to the rear wheel, motor cable, motor, derailleur, or derailleur hanger.
  •   Ensure your brakes are adjusted and bedded  
    Brake calipers may need to be adjusted to perform properly. New brake pads also need to go through a bedding-in process and may make some noise while braking until they are fully bedded.
  •   Double-check your cable routing  
    Make sure the cables are routed as shown in the assembly video. Proper routing helps reduce stress on the wiring and can prevent damage to your ebike's electrical components.
  •   Adjust your fenders  
    Fender rubbing can occur during shipping or assembly. Adjust the fenders to ensure there is no noise or tire contact during operation.
  •   Portola 02 Display  
    Learn more about your display features and settings.
  •   Portola 02 Battery
    The battery can be charged either on or off the bike. To partially release the battery, gently turn the key. To fully remove the battery, gently rotate the battery latch to the left or right to release it.
