Question 1

What range does the Cube Reaction Hybrid 625 Wh get?

Accepted Answer

With the 625 Wh battery: 100-130 km in Eco on rolling tracks, 60-80 km in Tour, 35-50 km in Turbo with climbing. Cold weather cuts range by 20-30%. The Purion display shows remaining range per mode; the Bosch Flow app (Smart System) refines the estimate per route. Find the complete answer on L'Atelier.

Question 2

How to care for the Reaction Hybrid's PowerTube battery?

Accepted Answer

Store between 30 and 60% charge in a dry room at 10-20 degrees C, never at prolonged 0% or 100%. Partially recharge every 2-3 months if unused. Bring the battery indoors in winter (cold cuts capacity). Clean the contacts with a dry cloth, lightly grease the rail with acid-free lubricant. Typical lifespan: 500-1000 full cycles.

Question 3

What do Bosch error codes (500, 503...) mean?

Accepted Answer

Code 500 is an internal drive unit error (often cleared by powering off and reseating the battery), 503 a speed sensor error (check the spoke magnet alignment), 504 a magnet tampering flag (anti-tuning). If the error persists after a reset and magnet check, only a dealer with the Bosch diagnostic tool can go further. Find the complete answer on L'Atelier.

Question 4

How often to replace chain and cassette on the Reaction Hybrid?

Accepted Answer

The Bosch CX's 85 Nm wears drivetrains 30-50% faster than a regular MTB: gauge-check the chain every 300-500 km and replace at 0.5% (11/12-speed). A chain replaced on time saves the cassette (2-3 chains per cassette). Prefer reinforced e-bike chains (Shimano LinkGlide, KMC e-series). Avoid Turbo starts in small crossed sprockets.

Question 5

Does the Reaction Hybrid's Bosch CX motor need servicing?

Accepted Answer

The drive unit is sealed: no internal user servicing. However, have the firmware updated by a Bosch dealer yearly, never use a pressure washer (seals), and check the motor mounting bolts (cradle bolts loosen with vibration, yearly torque check). A knock while pedalling is more often the BB or pedals than the motor. Find the complete answer on L'Atelier.
