We recommend checking your tire pressure every 3 weeks.

Remember to re-inflate your tires regularly: riding deflated reduces the autonomy of your battery, increases your pedaling effort and encourages punctures.
Before carrying out any work on your electric bike (cleaning, electrical or mechanical maintenance), remove your battery and switch off your EAB.
When wintering, charge your battery at least every 3 months.
-
Store/charge your battery in a cool (between +10°C and +25°C), dry place away from direct sunlight.
Do not store a discharged battery (1 LED flashing) to avoid deep discharging which could impair its capacity.
Remember to recharge the battery (even when not in use) at least every 3 months to avoid deep discharge.
If you can't charge your battery regularly, switch it to standby mode, even if 1 automatic standby occurs after 2 hours.
