4. Maintenance

Regular maintenance ensures the longevity and optimal performance of your OTIDA RX80 electric bike.

General Maintenance Tips:

• Battery Care: Charge the battery regularly, even when not in use, to maintain its health. Avoid fully discharging the battery. The integrated BMS protects against overcharge and overheating.
