When assembling your bike:
1. Charge Battery(s)
NOTE: Battery(s) may be delivered in a partially-discharged state due to shipping
regulations. Please fully charge battery(s) before your first ride.
See Battery Maintenance  section for more information.
2. Install wheel motor (Front wheel pictured).
These details apply to both front and rear wheel motors:
a. Install wheel into frame:
NOTE: Tighten the axle nuts ⅛ of a rotation
beyond where the  split washers appear
completely flattened.
b. Connect hub motor control cable:
NOTE: the arrows must be aligned for the 9-pin
connector to properly engage.

Tips for riding an e-assist bike:
● Before each ride, check that brakes are functioning correctly, and that all frame connections
and/or quick-release levers are secure.
● Start in a lower assist power setting (Setting 1 or 2), especially when the bike is new to you.
● Use only as much e-assist power as you need. This will help maximize battery life and keep
you aware of situations you encounter.
● Be aware of obstacles and loose surface (sand, gravel, etc.). You may be riding at faster
speeds than without electric assist, so give yourself extra time to stop or avoid these
conditions. The extra torque from the motor can make it easier to spin out in limited traction
situations.
● Be mindful of other cyclist, pedestrians, and vehicle drivers who may be surprised by the
rapid speed or acceleration of an e-bike rider.
● Charge batteries regularly to ensure maximum range is available for longer rides.
Troubleshooting:
If system will not power on:
- Check that all cable connections are fully seated, and free of moisture and corrosion.
(some are hidden inside controller bag)
- Ensure batteries are powered on and charged sufficiently.
If system powers on, but does not provide assistance:
- Set assist level at console to “1” - “5”
-Tap / to set assist level from 0-5
0 = no pedal assist power
1 = minimum pedal assist power
5 = maximum pedal assist power
- Check that motor cable connection is fully seated, and free of moisture and corrosion.
- Check that pedal-assist (PAS) magnet ring is in close proximity (1-3mm) to the
sensor. These components are mounted between the pedals/cranks. In some
situations, it may be possible for the magnet ring to get knocked out of position. The
PAS magnet ring should snug onto the bottom-bracket spindle toward the sensor, and
stay in position securely.

Battery Maintenance and Information
Grin Technologies LiGo Batteries:
Grin's modular LiGo battery was born in response to the massive transportation restrictions placed on
large lithium ebike packs. Properly certified batteries under 100 watt-hours are largely exempted from the
dangerous goods shipping restrictions and are even allowed aboard passenger aircraft with your carry-on
luggage when disconnected and powered off.
Connecting LiGo Battery Modules
Each battery module has two pairs of + and -
leads on them, which are terminated in
Anderson Powerpoles. That allows you to
easily plug any number of packs together in
parallel, and when you are done you have two
Anderson connectors left over. Typically one
connects to the controller and the other could
run lights or act as a charging port.
Turning on a LiGo Battery
For each battery, press and hold the button
until the first LED goes green, then
immediately release the button. The green
LEDs light up all the way and show the
battery’s current charge level. Then, one
LED will show a green “heartbeat” pulse for
approximately 20 minutes to confirm that
the battery is on.
Press and hold the button until the first LED
goes red, then immediately release the button.
An animation of red LEDs will scroll down to
confirm that the pack has turned off. The
battery should be turned off for shipping,
airline travel, or extended storage.
The battery may be connected to a computer
or phone to check battery usage history, adjust
BMS settings, and upgrade the LiGo firmware.
Press and hold the button until the first LED
turns blue (approx 3 sec). On releasing the
button, you will see the blue LEDs flash
indicating that the device is broadcasting and
is discoverable. It will exit bluetooth mode after
2 minutes of no connection, or in response to
a button press.

Battery Maintenance Notes:
- During regular use, it is fine to leave the battery packs on when not riding and while
charging.
- Before periods of disuse longer than several weeks, ensure the battery is fully charged and
then turned off.
- When storing the bike without riding for a month or more, plug the battey into the charger
approximately once a month to ensure battery is topped off with a full storage charge. This
will help maintain overall battery health.
