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.
