Product Information

Full details

The Cube Reaction Hybrid Pro 800 is a versatile hardtail e-MTB designed for adventurous riders who demand both high performance on technical trails and reliable comfort on long-distance excursions. Featuring the powerful Bosch Performance Line CX drive unit and an integrated 800Wh battery, this bike excels at providing smooth, whisper-quiet pedal assistance, though its robust frame construction results in a heavier overall weight compared to non-electric mountain bikes.

FAQs

How long does the 800Wh battery last?

Battery range varies significantly based on ride mode, terrain, rider weight, and temperature, but the 800Wh capacity is designed for long-range performance.

Can I upgrade the suspension later?

Yes, the frame is compatible with standard 120mm travel mountain bike forks if you choose to upgrade in the future.

Is the bike waterproof?

The electronic components are weather-sealed, but you should avoid submersion in water or cleaning with high-pressure jets.

What tire width is supported?

The bike comes equipped with 2.6-inch tires, which offer a great balance of comfort and grip for hybrid trail use.

Does the dropper post require maintenance?

Yes, the dropper post should be wiped clean after muddy rides and periodically checked for air pressure according to the manufacturer's manual.

Troubleshooting

Motor assistance feels intermittent or weak

Check that the battery is fully seated in the frame and inspect the speed sensor magnet on the rear wheel for proper alignment.

Brakes feel 'spongy' or have poor bite

The hydraulic system may require a bleed to remove air bubbles, or the pads may need cleaning to remove surface contamination.

Difficulty shifting gears

Check the rear derailleur hanger for alignment and adjust the cable tension using the barrel adjuster on the shifter.

Pros and Cons

Pros

  • Large 800Wh battery capacity for extended ride times
  • High-performance Bosch motor system
  • Precise Shimano XT shifting components
  • Agile and responsive frame geometry
  • Excellent stopping power with 4-piston hydraulics

Cons

  • Heavier weight due to robust battery and motor integration
  • Hardtail design lacks rear suspension for extreme technical terrain
  • Size-specific frame options may require careful fitting

Setup, Compatibility & Care

To ensure peak performance, follow these guidelines:

  1. Suspension Setup: Adjust the air pressure in the RockShox Recon Silver fork according to your body weight to achieve the correct sag for your riding style.
  2. Battery Maintenance: Keep the 800Wh battery charged between 20% and 80% if storing the bike for long periods to preserve cell health.
  3. Brake Bedding: New brake pads require a bedding-in process; perform several controlled stops from moderate speed to maximize braking efficiency.
  4. Cleaning: Use low-pressure water and mild soap. Avoid high-pressure washers, which can force water into sensitive electrical connections and bottom bracket bearings.
  5. Drivetrain Care: Clean and lubricate the Shimano XT chain regularly to ensure smooth, quiet gear changes and prevent premature wear of the cassette.
