Troubleshooting

Motor not providing assistance

Check that the battery is securely inserted and charged. Ensure the bike is in the correct assist mode using the Purion 200 remote. Verify that the speed sensor is clean and properly aligned.

Battery not charging

Ensure the charger is properly connected to the battery and a working power outlet. Check the charger's indicator lights. Clean the battery contacts.

Gears not shifting smoothly

Check for obvious damage to the derailleur or shifter. Ensure the cable is not frayed. Adjust the derailleur indexing if necessary, or consult a bike shop for professional tuning.

Brakes feel weak or spongy

Check brake pad wear. Air may be present in the hydraulic system, requiring a brake bleed. Consult a qualified mechanic.

Suspension feels harsh or unresponsive

Ensure suspension pressures are set correctly for your weight. Check that lockout features are disengaged. Inspect fork stanchions and shock seals for dirt.

Pros and Cons

Pros

  • Powerful Bosch motor for excellent climbing and extended range.
  • Full suspension design enhances comfort and control on rough trails.
  • Versatile geometry and adjustable leverage rate for customized ride feel.
  • Integrated battery system with easy removal and upgrade options.
  • Durable Alpha Platinum Aluminium frame built for off-road abuse.

Cons

  • Standard 600 Wh battery may require upgrades for very long rides.
  • While capable, it's positioned as a mid-level e-MTB, with higher-end components available on other models.
  • Internal cable routing, while clean, can sometimes complicate maintenance.

Setup, Compatibility & Care

Initial Setup: Upon receiving the bike, ensure all components are securely fastened. The bike typically comes partially assembled. Professional assembly is recommended to ensure correct setup of brakes, gears, and suspension. Consult the owner's manual for detailed instructions.

Battery Care: The 600 Wh PowerTube battery is removable. For charging, use the provided Bosch charger. Store the battery in a cool, dry place, ideally with a charge level between 30-60% for long-term storage. Avoid extreme temperatures.

Suspension Care: Keep the fork and rear shock stanchions clean. Regularly wipe them down with a soft, damp cloth after riding to remove dirt and debris. Refer to the RockShox and Trek suspension manuals for specific maintenance schedules regarding seal cleaning and lubrication.

Drivetrain Maintenance: Clean and lubricate the chain regularly. The Shimano CUES drivetrain is designed for durability, but regular cleaning will ensure optimal shifting performance. Check derailleur alignment periodically.

Brake Care: Ensure hydraulic disc brake pads and rotors are clean. Avoid contamination with oils or lubricants. Check brake fluid levels periodically and have them serviced if performance degrades.

Cleaning: Use mild soap and water with a soft brush or sponge to clean the frame and components. Avoid high-pressure washers, especially around bearings and the motor.

Upgrades: The bike is compatible with an 800 Wh battery upgrade and the Bosch PowerMore booster battery. These can be retrofitted by a dealer.
