Always refer to the Turbo bike and/or charger manual for detailed information about charging. Here are some key points:

  • Only use original and compatible chargers with Specialized e-bikes
  • Do not use the charger with any other bicycle or any other charger with Specialized e-bikes, even if it fits
  • Turn off the battery, unplug the charger from the battery and remove the battery from the bicycle before performing work of any kind, such as installation, maintenance, cleaning, repair and/or transportation
  • When charging the battery:
    • Regularly inspect the charger, cable, and charging plug for damage. Never use a charger that is damaged
    • Make sure the charging socket and plug are dry before connecting and charging the battery
    • Only use the Specialized charger supplied with the bicycle or other chargers approved by Specialized

Charger Overview

3h 35min

3.0+/-0.3A
= 1.0+/-0.1A (RE) + 2.0+/-0.2A (Int.)

*Note: Due to a lower charging current, charging the RE alone takes longer than charging the internal battery and as long as charging RE + internal battery through Y-cable. The reason for slower charge times is to maintain battery health for riders (higher currents would stress the cells and decrease health quicker).
