Levo Retailer Technical Guide
Requirements & Recommendations
Required Tools
Turbo PC Connect and Diagnostic Tool,
version 4.2 or later : 989E-5610
This is an updated version of the existing Turbo PC Connector
(aka Turbo Diagnostic Tool). This tool is used exclusively to
update the Levo system firmware of the motor and battery.
All system diagnosis can be performed electronically with the
Mission Control App or manually with the diagnosis techniques
outlined in the Troubleshooting Guide section of this guide.
To update the motor firmware, the Levo Diagnosis Tool Adapter must
be used in conjunction with Turbo PC Connect and Diagnostic Tool.
Note: previous versions of the Turbo PC Connect and
Diagnostic Tool will only update the battery firmware. The
previous versions will not update the motor firmware.
Levo Diagnosis Tool Adapter : 98916-5646
The adapter must be used with the Turbo PC Connect
and Diagnosis Tool to update the motor firmware. In
addition, the battery must be connected to the motor
while the Turbo PC Connect performs the update.
3" 2-jaw pulley and gear puller
These tools are typically available at auto parts and/or hardware stores.
The ends of the jaws must be thin enough to fit between the chainring
spider and motor cover. The force required to pull the spider is low.
Therefore, if the ends of the jaws need to be modified or ground
down to fit between the spider and motor, that is acceptable.

5
Levo Retailer Technical Guide
Requirements & Recommendations
Brose spindle cover : S175300006
This tool holds the threaded plunger of the gear puller stable.
It applies force to the driver when the spider is pressed on
which helps to prevent damage to the torque sensor.
Smartphone or tablet : Android or iOS
System requirements: Android 4.3 (Jellybean) or later, iOS 8.1 or later.
All Levo system diagnosis and user customization is
performed through the Mission Control App. Unlike the Turbo,
system diagnosis and user customization is not possible
through the Turbo PC Connect and Diagnostic Tool.
Octalink/Isis bottom bracket tool
Use Shimano®®TL-UN98, Park BBT-18, or
an equivalent bottom bracket tool.
This tool is used to tighten or loosen the spider lockring.

Levo Retailer Technical Guide
Requirements & Recommendations
Recommended Tools
Counterweighted or powered repair stand
EVT E-Z Lift and Park PRS-33 Powered Lift Stand are two
options for counterweighted or powered repair stands.
While these stands are expensive, they are a worth the investment.
E-bikes are considerably heavier than standard bicycles. A
counterweighted or powered stand minimizes the physical
effort required to position the bike and reduces the potential
for injury to retailer staff when they lift the bike. The bikes can
be easily maneuvered in the stand which reduces the potential
for damage to the bike while showcasing to Levo riders a level
of professionalism that inspires confidence in the retailer.
Handlebar/stem mounted phone holder
Hondo Garage Perfect Squeeze, Ram Mounts, and Rokform Mounts
are three options for handlebar/stem mounted phone holders.
Remember, all Levo system based diagnosis and user
customization is performed through the Mission Control App.
The best diagnostic method is to use the app's real time data
display while riding the bike. Using a handlebar or stem mounted
phone holder allows the mechanic to ride safely, with both hands
on the handlebar, and view the app at the same time to compare
the motor performance with respect to speed and rider input.

Levo Retailer Technical Guide
Requirements & Recommendations
Recommended Service Parts Inventory
This section outlines a small inventory of critical replacement parts that a retailer should keep in stock to help diagnose issues effectively
and efficiently. Diagnosis of a Levo drive system issue typically requires the replacement of various components of the system with
known functional parts to determine which components are functional or non-functional through a process of elimination. It is much
like finding a creak in a bike. A small inventory of parts will save considerable time and money on ordering and shipping replacement
parts individually for diagnosis purposes. In addition, some components are wear items that a Levo retailer will want to have in stock to
perform service for their customers.
Magnet holder including magnet plate,
anodized black : S166800012
The drive system must recognize the bike is in motion before
it can activate the motor. Motion is detected when the magnet
mounted on the rear brake rotor passes a reed switch in the
speed sensor. The speed sensor then sends a signal to activate
the motor. The motor will not provide power if the magnet is not
attached to the rotor. Riders with multiple wheel sets will need
a magnet on each wheel that is used with the Levo or the rider
will need to transfer the magnet to the other rear wheel rotor.
Recommended inventory: 2-3
Motor-to-battery harness : S176800002
Specification change - S176800002 replaces S166800008
and is backward compatible. S176800002 is a longer harness
length of 180 mm versus the original 165 mm length.
Riders who frequently unplug the battery from the system will
wear out the connector which will require replacement.
Remember, to diagnose system issues, various parts,
including wire harnesses, must be replaced with a known
functional part to eliminate it as a source of the issue.
Recommended inventory: 1
Speed Sensor : S166800018
The speed sensor, much like a traditional cycle computer, is a
wire with a reed switch at the end. While a reed switch rarely
fails, if it does, or if a rider damages the speed sensor, the motor
will not receive a signal to activate and will not operate.
Recommended inventory: 1-2

Levo Retailer Technical Guide
Requirements & Recommendations
Chainring steel, 104 BCD : S161400009
This is a 104 mm BCD chainring made specifically for Levo by Praxis
Works. There are two features that make the chainring ideal for Levo:
• It is made of steel for durability.
• It has internal threads for the chainring bolts which eliminates
the need for backing nuts. If the chainring had backing nuts,
the spider would have to be removed to install the chainring.
While standard 104 mm BCD chainrings are compatible with the
Levo spider, performance could be compromised because:
• Most standard chainrings are made of aluminum and
will wear more quickly than a steel chainring.
• Most standard chainrings do not have internal
threads for the chainring bolts so the spider
must be removed to install the chainring.
• Use of a chainring larger than the stock 32T may inhibit climbing
and make larger gears less useful because the larger gears will
be difficult to engage until the speed is above the speed limiter
(i.e. the speed is above the limit where the motor is required to
turn off).
Refer to the First Ride Tips later in this guide for climbing tips.
Max chainring: 36T with chain guide; 38T without chain guide
Recommended inventory: 1
Amazinger 2.0 Derailleur Hanger : S162600002
A straight, aligned derailleur hanger is more critical to shift
performance on a Levo bicycle versus a traditional bicycle because
the motor applies more torque through the rear of the bike. Any
misalignment of the derailleur hanger can cause shifting issues.
Retailers should encourage Levo riders to purchase a spare hanger
and keep it on hand in case the hanger is bent during a ride.
Battery mounting thru axle : S166800004
Levo riders who frequently remove the battery from the bike to
charge the system will most likely need to replace the thru axle
because of increased wear, damage, and/or loss of the axle.
Recommended inventory: 2

Levo Retailer Technical Guide
Build, Setup, & Maintenance
This section outlines the specific Levo components that have unique build, setup, and maintenance requirements. When a new Levo
bike is built or prepared for a test ride, demo, or sale, please pay attention to the following items to ensure rider safety and optimal
performance of the bike.
New Bike Build Checklist
Confirm that the rear derailleur hanger is straight
A straight and aligned derailleur hanger is more critical to shift
performance on a Levo bicycle versus a traditional bicycle.
Remove the right crankarm and confirm that the spider
lockring is tight
Hold the chainring with a chain whip or apply the rear brake
with the chain in the small cog, then tighten the lockring until
it bottoms out. The lockring is a standard right hand thread.
Confirm that the crankarms are tight
The crankarms are visually identical but can be identified
by the "R" and "L" on the back. Confirm the crankarms
are on the correct side of the bike and tight.
Confirm that the chain guide is properly adjusted
All Levo bikes: remove the stainless steel shim between
the guide and the motor cover unless there is contact
between the outer guide face and chain.
FSR Levo bikes: compress the suspension to make sure the
chain just rubs the guide when the chain is in the lowest gear.
Hardtail Levo bikes: adjust the guide so that the chain nearly
rubs the guide when the chain is in the lowest gear.
Confirm that the motor operates properly
Test ride the bike to verify the drive system is functional.

Levo Retailer Technical Guide
Build, Setup, & Maintenance
Setup Checklist for Test Rides, Demos, and Sales
Adjust the saddle height
Levo bikes do not have room inside the frame to accommodate
cable slack. As a result, the Command Post cable must be pulled
from or pushed into the front of the bike when the saddle height
is adjusted. To adjust the saddle height complete these steps:
1. Remove the battery.
2. Unclip the Command Post cable from
the downtube cable guides.
3. Adjust the Command Post cable as the saddle height is adjusted.
4. Have the rider check the saddle height by test riding the
bike with the battery removed and the system off.
Note: there is no additional pedal resistance in the
drive system when the motor is not activated.
Adjust the suspension
Suspension setup on a Levo bike is nearly the same as a traditional
bike. The primary difference is that it is necessary to account for
the additional weight of the drive system - which is located on the
frame and is considered a sprung mass above the suspension.
The increase in weight requires an increase in spring rate for both
the front and rear suspension. In addition, the rebound damping
settings should change to reflect the increase in spring rates.
When a bike is set up using the standard Static Suspension
Process, the need to increase the suspension spring rate is not
obvious; however, it is necessary. For example, when a rider
switches from a traditional bike like an Enduro with a RockShox
Pike set at 80 psi and 5 clicks from full slow (FFS) to a similarly
equipped Levo, the rider will likely set the Pike at 85-90 psi and
3-4 clicks FFS to achieve the same ride response and feel.
Adjust the tire pressure (6Fattie)
Many riders who ride 2-2.5" width tires gauge tire pressure by
squeezing the tire by hand. For Levo bikes this method typically
results in under inflated tires. The extra weight of the Levo bike
requires higher pressure and the wider 3" tires have enough
volume that a pressure change as little as 1 psi results in a
noticeable change of performance. To help riders consistently set
their tires properly, start riders with 16-18 psi in the front tire and
18-20 psi in the rear tire (depending on rider weight). Be sure to
stock, sell, and consistently use a quality tire pressure gauge.

Levo Retailer Technical Guide
Build, Setup, & Maintenance
First Ride Tips
Whether a first time Levo rider is on a test ride, demo, or post-purchase ride, the following tips will help a new Levo rider quickly learn
the capabilities of the system and get more out of the first ride experience. Remember, Levo motor support is available in three different
drive settings: Turbo Mode, which provides 100% support while pedaling; Trail Mode, which provides 50% support while pedaling; and
Eco Mode, which provides 20% support while pedaling. The factory default mode for the Levo motor is Trail Mode.
Be sure to inform the rider which mode the motor is set in so know what to expect while pedaling and give them the additional tips
below:
Shift before you need to
Pedal at a higher cadence than you are used to
Continue to pedal on climbs to allow the motor to do most
of the work
The motor will automatically shut off if it does not receive a signal,
generated when the magnet passes the speed sensor, after 0.2
seconds. This is roughly equivalent to 6 ft (2 m) of trail and can
easily occur on slow cadence climbs or from a 'mashing' style
of pedaling. Encourage riders to pedal at a higher cadence.
Remember, in order for the motor to activate and provide
power, the system must recognize the bike is moving which is
accomplished when the magnet passes the speed sensor.
In addition, the higher bottom bracket height and shorter crankarms
on the Levo allow the rider to pedal over more obstacles.
Use lower power settings on loose and/or technical terrain
Higher power can result in wheel spin, loss
of traction, and trail damage.
Use a lower saddle position on technical climbs
An efficient climbing position (i.e. saddle height) is not necessary
when the motor is activated on a climb. A lower saddle
position allows the rider to maximize control of the bike.

Levo Retailer Technical Guide
Build, Setup, & Maintenance
Maintenance Details - Bicycle
Maintenance for the Levo system is similar to a traditional bike. Much like a traditional bike, there are some components that are
sealed that do not require routine maintenance. However, the Levo system does have some components that require more frequent
maintenance due to the increase in distance traveled that causes faster wear. In addition, because of the higher cost of some
components, it is important to perform maintenance routinely to extend the life of the parts.
• Always turn the battery off and disconnect the charger prior to cleaning the bicycle. Leave the battery attached to the bicycle when
cleaning the bicycle; the battery prevents water from contacting electrical interfaces.
• Do not use a pressure washer to clean the bicycle. The use of a pressure washer on the bearings or near the area of the chainring/
spider area will cause premature wear of the bearings and will void the warranty.
• To clean the battery, remove the battery from the bicycle.
• Do not allow water to contact electrical components.
• Routinely check that the rear derailleur hanger is straight and aligned.
• Encourage Levo riders to frequently replace the chain. A worn chain will increase wear on the drivetrain, particularly the cassette.
• The following wear items will wear more quickly on a Levo bike because the rider will travel a further distance in a shorter amount
of time: drivetrain components, including the chain, cassette, and chainring; brake pads; tires; and suspension components.
• Suspension service should be sold pro-actively, particularly for Levo bikes because they typically have increased mileage over
traditional bikes.
Maintenance Details - Motor
• Do not use a pressure washer to clean the bicycle. The use of a pressure washer on the bearings or near the area of
the chainring/spider area will cause premature wear of the bearings and will void the warranty.
• The Levo motor bearings are high quality and have been tested to several thousand miles. When maintained properly they should
last for several years.
• The Levo motor is a non-servicable component. Damage to the Levo motor bearings requires replacement of the entire motor unit.
The most frequent cause of damage to the motor bearings is the use of a high pressure washer to clean the motor. This damage is
not covered by warranty. Replacement cost of the Levo motor unit is in excess of $1000 USD.
Unlocking or De-restricting the Motor
Unlocking or de-restricting the Levo motor, by any means including software or hardware modification, is not permitted
and will void the warranty.

Levo Retailer Technical Guide
Glossary
This section provides the definition of some common technical terms used in e-bike systems.
Battery Management System (BMS)
The computer software that monitors the function of the Levo Drive System. The BMS, in conjunction with a fusible link,
prevents damage to the Drive System when any system anomaly is detected.
How it works
The BMS will restrict electric power to the Drive System when the motor and/or battery experience these temperature
conditions:
motor - warm
battery - warm (while riding)
battery - warm (while charging)
battery - cold (while charging)
The BMS will shut-off electric power to the Drive System when the motor and/or battery experience these temperature
conditions:
motor - hot
battery - hot (while riding)
battery - drawing too much current (while riding or charging)
battery - voltage imbalance (while riding or charging)
Capacity (Wh)
The total amount of energy a battery can store. A Watt-hour is the measure of electrical energy capacity that relates power and
time. For example: a battery listed as 460 Wh capacity means that when it is drained from 100% SoC to 0% in one hour, it will
supply 460 W of power. Similarly, a 504 Wh battery will supply 504 W in one hour.
A battery with a larger capacity will provide:
• Longer range per charge, just like a larger gas tank in a car would provide longer range.
• Longer overall battery life; the larger capacity means fewer charge cycles over the lifetime of the battery.
• Longer charge times, just like a larger gas tank in a car would take longer to fill.
• Higher cost; larger capacity batteries cost more.
The 460 W battery is the OE specification for all Levo models except the Expert and S-Works.
The 504 W battery is the OE specification for the Expert and S-Works Levo models. It is also available in AM applications and
for warranty.
Charge Cycle
When the battery level is used from 100% charge (full charge) to 0% charge (depletion) then charged from 0% to 100%.
If the battery level is used from 100% to 50% and is then charged back up to 100% this is only a half charge cycle. Note: a
charge cycle is not counted as every time the bike is plugged into the charger.
Drive System
The components of a Turbo bike that make it an electric pedal-assist bicycle. For Levo, the Drive System is comprised of five
components: the motor; battery; motor to battery wiring harness; speed sensor; and speed sensor magnet.
How it works
For the drive system to operate, all five components must be connected and function properly. If any of the components is not
connected or malfunctions the system will not operate.

Levo Retailer Technical Guide
Glossary
Lithium-Ion (Li-ion)
Modern battery technology that is used in all Specialized Turbo bikes. These are the same type of batteries that are used in
modern computers, phones, electric cars, and many other electric powered consumer products. For marketing purposes, some
companies may use terms such as: Li-po; Lithium Polymer; or Lithium Cobalt to make the batteries sound more technologically
advanced. They are, in fact, all types of Lithium-ion cells.
Some of the key advantages of Li-ion batteries include:
• They do not suffer from 'memory effect'. Li-ion batteries can be charged from any level of charge present; they do not have
to be depleted before charging. Older battery technologies such as Nickel cadmium (NiCad) and Nickel Metal Hydride
(NiMH) had to be depleted before charging or they would 'remember' the smaller capacity if only partially discharged before
charging.
• They offer a large capacity (range) at a low weight.
• There are many reputable manufacturers to choose from.
Maximum Power
The maximum amount of power a motor is capable (or allowed) to put out. The maximum power can be significantly more than
the nominal power. However, the motor and/or motor system will not be able to sustain the maximum power for long without
overheating.
Unit of Power: Watts (W); 748 W = 1 hp
Nominal Power
The amount of power the motor provides under normal operating conditions without generating excess heat. Typically, the
nominal power is used by government agencies as a way to categorize e-bikes.
Unit of Power: Watts (W); 748 W = 1 hp
State of Charge (SoC)
The percentage of total energy stored in the battery that is available to the rider.
Note: the charge amount the rider can access is between 0-100%. Theoretically, Li-ion batteries can be charged more and run
down further than the BMS allows, but at the risk of a significantly shortened battery life.
State of Health (SoH)
The percentage of total energy the battery can store compared to its capacity when new. Li-ion batteries gradually lose a small
amount of energy capacity with every charge cycle, which decreases the battery's range over time.
Note: while the SoH gradually decreases over time, the SoC refers to the percentage of available energy, which will always
show as 0-100%. The output performance of the battery remains the same, but its capacity and therefore range, decreases
over time. The BMS in the Turbo family of bikes is designed to maintain a very high SoC for a long time.
User Interface (UI)
The means of communications between the rider and bike. While technically this would include the sensor in the motor we
usually use this term for the motor assist and power controls, as well as any display.

Levo Retailer Technical Guide
Troubleshooting & Diagnosis Guide -
Fundamentals
This section outlines the basic process for troubleshooting and diagnosing drive system issues for all Specialized Levo bikes. The Levo
system is simple compared to other ebikes. It has six easily replaceable components: the motor, battery, wiring harness, speed sensor,
magnet, and charger.
The basic troubleshooting process entails that you:
• Get a description of the issue from the rider
• Determine if the issue is function or performance related
• Diagnose the issue
• Call Retail Care for additional support
The following provides a more detailed look at each step in the process.
Get a Description
Get a full description of the symptoms, riding conditions, and typical maintenance and care practices from the rider. Ask probing
questions about what the rider experienced, such as: what was the situation when the issue occurred, what were the riding conditions,
how was the bike maintained, and were any changes made to bike including changing components not related to the drive system.
Some common symptoms, riding conditions, and maintenance habits to ask about and listen for include:
Symptoms Riding Conditions Maintenance and Care
Noise, grinding
Noise, squeaking
Noise, clunking
Looseness
Decrease in power
Changes in performance
Intermittent power
Reduced range
No power
Does not turn on
Beeping from battery
Messages on app
Communication problems with app/other
device
Ambient temperature and weather
Macro terrain - mountainous, rolling, flat,
straight, twisty, etc
Micro terrain - soil type, soil moisture,
rocks, roots, dusty, etc
Riding style - stand & hammer vs. sit &
spin, accelerate hard or easy, attack climbs
and descents
Length of ride
Charge level at start and finish
Rider defined settings
Mode setting
Bike transport method - ridden to trail, roof
rack, back of pickup/tailgate pad, kept in
car, battery removed or installed etc
Charged to full capacity immediately after
every ride
Stored after a long ride
Stored for extended times
Ambient temperature - charging
Ambient temperature - storage
Cleaning methods - garden hose, bucket
and brush, pressure washer, not usually
washed
Drive system changes or additions - motor,
battery, harness, magnet, speed sensor,
charger
Any other component changes - drivetrain,
tire size/type, wheels, brakes, connected
devices, trailers
Determine the Issue
All Levo drive system faults or errors are either performance or function related issues. To resolve either type requires a different
approach.
PERFORMANCE
Performance issues are defined as when the system works but not to the rider's expectations. The information gathered in the Get a
Description process will help expedite the diagnosis of performance issues especially if a Rider Care consultation is required.
FUNCTION
Function issues are defined as when the system does not work. For example, if the battery turns on but no power is transmitted to the
wheel. This type of issue is most often due to one single component that is faulty, damaged, or missing. It can also be the result of a bad
connection between components. It is rare for more than one component or connection to be faulty at the same time.
The core elements of functional issue diagnosis are: visual inspection of components, using the Mission Control App, and substituting
components.

Fundamentals
Diagnose the Issue
Prior to diagnosing any issue, performance or functional, the system to meet the following Conditions of Operation for the motor to
activate:
CONDITIONS OF OPERATION
• The battery must be charged and turned on
• The battery must be connected to the motor
• The motor must be operational
• The speed sensor must be connected
• The magnet must be installed on the rear wheel
• The rider defined settings must allow power via the Mission Control app
• The rider must apply torque to the cranks
• The bike speed must be greater than zero but less than 20 mph (US & Canada), 25 km/h (elsewhere)
PERFORMANCE DIAGNOSIS
The best approach to diagnose a performance issue is to:
• Categorize the issue
• Understand the rider's expectations
• Understand the situation that resulted in the perceived issue
• Attempt to correlate the rider's perception with data based values from the Mission Control App
• Test ride the bike with known good components installed as a comparison.
Again, the insights from the Get a Description process will provide valuable information on how the rider's input to the bike impacts the
issue.
Detailed information about common performance issues and how address them are found in the next section Troubleshooting &
Diagnosis - Performance Issues.
FUNCTION DIAGNOSIS
Function issues or faults are typically due to a single component that is damaged, defective, or is not properly connected. Review the
rider's responses from the Get a Description process and adhere to the Conditions of Operation while you perform:
• Visual inspection - check the connections and components that are visible before removing any of them.
• Check connectivity with the Mission Control App - specific types of data are transmitted to the app if there is a proper connection.
• Substitute components connected to the motor - removal of the left crankarm and motor covers allows access to the entire drive
system.
