Verify that your e-bike uses a 48V lithium battery requiring a 54.6V 2A charger with the STC-8137LD connector. Confirm your mains supply falls within the 100-240VAC 50/60Hz world-wide input range. Ensure the 10 ft total cord length reaches your charging location without an extension lead.

This adapter replaces a lost, damaged or worn-out factory charger for the same RadCity models.
