RF350 Quick Start Guide:
1. Carefully remove contents of box out of the packaging.
You will find:
• 1 x RF350 eBike
• 1 x 110V Charger
• 1 x mud guard (optional)
• 1 x Rear rack (optional)
• 2 x Keys
2. Fold open the eBike and close the quick release latch on the frame.
3. Install Front wheel and tighten quick release latch.
4. Place handle bar in place and tighten allen screws
5. Place seat to desired height and tighten quick release latch.
6. Inflate tires to about 35-40PSI
7. Place your RF350_Zpao350 on a raised surface for easy inspection while securing one of the
wheels so it stays in place then proceed to visually check the RF350 components and ensure
that all screws and bolts are tightened and that tires are correctly inflated. Check and adjust
break lever to your preference and check that the derailleur functions properly. This is
usually already done once at the factory and once before shipping but as a precautionary
measure we recommend you do this as well before riding.
8. Charge your RF350 in a clean environment at ambient temperature until light on the charger
turns from red to green. You can charge the battery while still inside the frame of the eBike
or you may remove the battery and charge it independently. To remove the battery pack
open the quick release latch on the frame and fold the eBike, insert the key under the
frame, push and turn it clockwise until the lock pin goes inside the battery. Remove the key
and slowly pull out battery pack. Repeat process in the inverse order to re insert the battery
pack into frame.
9. Once you've familiarized yourself with the digital display you will be ready to ride. Please
ride carefully! (see attached instruction for OMOT-M3 display)

Maintaining your RF350 battery pack:
Before shipping, each and every transporter is checked for overall quality control and condition of
battery pack. Battery is tested and fully charged before shipping.
The lithium ion technology is intended to last for several years while being charged and discharged many
times. However, the battery's life span will depend on your care of the battery.
Battery life will depend on your maintenance and care of the battery. RF350 uses advanced Lithium-Ion
batteries made with high capacity LG cells and they should be charged at least once a month (when not
in use) to ensure the longevity of your battery. Make sure to only use our supplied 48V charger on your
48V battery.
Allow your battery to rest for 10 minutes after charging before riding and for 10 min after riding before
charging. Unplug your battery charger after the light turns green indicating your battery is fully charged.
Always unplug the charger from the wall outlet before plugging or unplugging the other end into your
RF350.
Typical charging time after the battery has reached the 10% critical low level is between 5 to 6 hours.
Caution: Do not expose your battery to extremely low or high temperatures to avoid potential damage
to your battery.»
