Symptom
Conditions
Typical Cause
How to Address
Intermittent
power
Motor shuts off even while the
bike is moving and the rider is
pedaling
Loose or damaged motor or
speed sensor connectors
Inspect/replace the harness and/or speed
sensor as necessary.
Bikes that had a motor replaced
in 2016 require a firmware update
Update battery firmware to 2.12.1 (504 Wh
battery) or 4.12.1 (460 Wh battery)
Motor shuts off while climbing a
steep hill
Typically happens when a rider is
pedaling with a slow (mashing)
cadence. The slow cadence
and wheel speed causes the
drive system to shut off power.
The motor will stop power if it
does not receive a signal after .2
seconds.
The motor typically provides
power again once the cadence
and wheel speed increase.
Educate the rider on how to get the best
climbing performance from the Levo:
• Shift earlier than necessary
• Pedal at a higher cadence than normal by
using lower/easier gears
• Continue to pedal on climbs to engage the
motor
• Use shorter cranks for better pedal
clearance
• Use a lower saddle position
No motor assist after a ride
delay and the battery turned off
The battery automatically turns
off after ten minutes without rider
or speed input
Educate riders about this feature, it is
common to all Turbo and Levo bikes.
Inability to
change mode
Motor feels like it is in Turbo
mode even when the mode is
changed to Trail or Eco
Faulty data connection between
the battery and motor.
This will cause the Mission
Control App to not display bike
data even though the motor
works (the motor only re
and - to function)
Verify that no motor or ride data transmits
to the Mission Control App
Inspect the female data terminals - the five
small connectors adjacent to two power
terminals - in the harness/motor plug. If the
data terminals are spread too wide, use a
sharp pick or similar tool to push them back
into place.
Inspect the male data pins on the motor
plug end of the harness. If they are bent
they can be carefully bent back into place.
If any pins are broken or visibly shorter than
the other the harness should be replaced.
