The core maintenance principles
CEMOTO's owner manual sets out a small number of maintenance rules that cover most of what matters:
1. Battery and charger
Use only the included battery and the included battery charger. If either is discontinued or out of service, replace it immediately with the recommended part supplied for your model. Using a non-certified charger voids the battery warranty and creates a fire risk.
2. Wheels and drive system
Wheels and drive system components wear normally with use. It is the rider's responsibility to systematically check the wheels for excessive wear and to properly adjust and replace drive system components as needed.
3. Spare parts
Most common spare parts are available through CEMOTO distributors and the accessories range.
4. Electrical components are not user-serviceable
The electrical elements can only be cleaned on the outside. There is no need to maintain the inside, and you should not open them yourself. Opening sealed electrical components voids the warranty on those parts.
5. Do not overload
Overloading damages the electrical components — plastic parts can deform from high temperature, or the fuse socket can be damaged by heat. Overload damage is not covered by warranty.
6. Cut the power when not in use
For safety, cut the power supply when the bike is not being used. Turn the power switch off when the motorcycle is not in use.
7. Clean only the exterior
Never pressure-wash bearings, seals, connectors or the motor. See Cleaning & Storage.
Fastener check reminder
Fasteners settle after assembly and during the first rides. After your first 20–30 minutes of riding, re-check:
Front and rear axle nuts
Handlebar stem clamp bolts
Brake caliper mounting bolts
Pedals
Motor mounting bolts
Suspension mounting bolts
Use the values in Torque & Fastener Reference.
The chain tension rule
Chain slack should be approximately 15 mm. Check it frequently — chain tension affects drivetrain noise, wear rate and the risk of derailment. Adjustment procedure: loosen the rear axle nuts, adjust the tension screw, then retighten the axle nuts.
See Drive & Transmission.
Tire pressure rule
Check air pressure frequently. If the pressure is too low, rolling resistance increases and the riding range is reduced. Under-inflation also risks damaging the rim and pinching the inner tube.
Use a hand pump with an integrated pressure gauge and a Schrader-type valve. Do not use a pressurized gas-station air system — those are designed for car tires at much higher pressure and volume.
Serviceability by design
CEMOTO selects serviceable components deliberately: the range is built around standard, replaceable parts rather than proprietary assemblies, and compatible D-series parts and accessories are available through the CEMOTO accessories range. This means:
Wear items (pads, tires, chains, cables) can be replaced rather than requiring a whole assembly.
The controller is programmable and the display parameters are accessible.
A local bike shop can carry out most maintenance work.
Local bike shops can generally service most components, since most are standard. For warranty-related repairs, contact CEMOTO first to ensure coverage is preserved.

Battery Care & Charging
Battery practice for CEMOTO lithium-ion packs — charging, storage, temperature limits, transport and disposal.
Safety first. Lithium-ion batteries can be dangerous if mistreated. Never open, puncture, crush or short a battery. Never charge a damaged or swollen pack. Never charge with a damp socket. Charge away from children, pets and flammable materials.
Charging
Procedure
Insert the charger plug into the battery charging socket.
Insert the charger power plug into the power supply.
Charge fully: approximately 6 hours for 48V models, 7–8 hours for 72V models.
Disconnect from the mains first, then from the battery.
First charge
The owner manual recommends an initial charge of up to 12 hours for the first charge cycle, with a maximum charge time thereafter of 8–9 hours.
Charging rules
Rule
Reason
Use only the supplied compatible charger
Non-certified chargers are the leading cause of battery damage and void the battery warranty
Do not charge when the socket is damp
Water ingress in the charging circuit creates a short and fire risk
Use the correct power source for your market
D-series U.S. chargers use a two-prong plug
Keep away from children, pets and flammable materials
Fire safety
Charge in a dry, ventilated location
Heat and hydrogen venting must be able to dissipate
Do not leave a charging battery unattended for long periods
Fire safety
Do not charge a swollen, damaged or wet battery
Fire safety
Charging temperature
Charge at a normal ambient temperature. Extreme cold or heat permanently damages the battery. Many BMS units refuse to charge below freezing or above a high temperature threshold — if charging will not start, allow the pack to reach room temperature and retry.
Temperature and capacity
Usable battery capacity falls significantly in cold weather. CEMOTO's owner manual gives these reference figures:
Battery temperature
Approximate available capacity
14 °F
~70 %
32 °F
~80 %
70 °F
~90–95 %
This is normal lithium-ion behavior, not a fault. Expect a shorter range in winter on the same charge.
Storage and operating temperature
Never store the product frozen or at extremely high temperatures. The recommended storage temperature range quoted in the owner manual is approximately 68 °F (20 °C) down to 45 °F (7 °C). Extreme temperatures will permanently damage the battery.
In practice, for storage:
Keep the battery in a dry location away from freezing and away from direct sun.
Bring the battery to room temperature before charging in cold conditions.
Avoid leaving a fully charged pack in a hot vehicle.
Storage
Situation
Recommended action
Short-term (days)
Leave the battery on the bike, powered off, at around 40–70 % charge
Long-term (weeks to months)
Charge to approximately 50 %, remove the battery if removable, and store in a dry location within the recommended temperature range. Disconnect the battery from the bike so it does not slowly discharge
Storage off the bike
Store in a dry place, out of reach of children, away from flammable materials
Before riding again
Fully charge before use
Do not store a deeply discharged battery for an extended period — this causes irreversible capacity loss and may latch the BMS protection.
Do not leave the battery connected to the charger indefinitely.
Battery life
Detail
Average lifespan
1 to 2 years, depending on conditions and usage
Decline pattern
Gradual capacity loss over the battery's life, accelerating with heavy use and temperature extremes
Replacement trigger
Available capacity below 70 %, as measured by the discharge meter
Warranty term
12 months (D-series)
Practices that extend battery life
Avoid deep discharge — recharge before the pack is fully flat, and plan rides to return with reserve.
Avoid leaving the pack at 100 % or at 0 % for long periods.
Store at approximately 50 % for long idle periods.
Charge at moderate ambient temperature.
Use only the supplied charger.
Avoid sustained high-current use (continuous hard acceleration, heavy loads) where avoidable.
Keep connectors clean and dry.
Transport
Battery transport is regulated because lithium-ion cells are classified as dangerous goods.
Mode
Notes
Car / truck
Transport upright and secure so the pack cannot be punctured or shorted. Do not leave in a hot vehicle. Bring to room temperature before charging at your destination
Courier / parcel
Regulated. eBike batteries cannot be shipped to parcel stores or lockers — they must go to a physical address where someone can receive them. They may also be shipped separately from the bike body
Air
Heavily restricted. Check with the carrier before traveling, and never carry a damaged pack aboard an aircraft
Never
Never transport a swollen, punctured, wet or otherwise damaged pack in an enclosed passenger space
Disposal and recycling
This product contains sealed lithium-ion batteries and must be handled properly.
Do not dispose of the battery pack in a fire — the pack could explode.
Do not discard lithium-ion batteries in the garbage.
Do not mix old and new batteries, or mix battery chemistries.
Dispose of the battery according to locally applicable regulations.
Contact your local recycling / reuse or hazardous waste center for more information.
Many regions require lithium-ion batteries to be returned to a designated collection point. Many retailers also accept them.
Safety warnings
Reproduced from the CEMOTO owner manual:
WARNING: Do not dispose of the battery pack in fire. The battery pack could explode.
Do not mix old and new batteries. Do not mix alkaline batteries, standard (carbon zinc) batteries, or rechargeable (nickel cadmium) batteries.
The product contains lithium-ion batteries, which must be disposed of according to locally applicable battery regulations.
Additional safety guidance:
Never short the battery terminals.
Never open the battery case or tamper with the seals.
Never attempt to revive a swollen or damaged pack.
If a battery emits an unusual smell, becomes hot, swells or vents, move it away from combustible materials and contact emergency services if there is any fire risk.
Charge only with the supplied charger in a dry, ventilated location, away from children, pets and flammable materials.
Battery warranty exclusions
Battery warranty does not cover failures caused by:
Use of non-certified chargers
Overcharging or deep discharge
Physical impact or water intrusion
Seal tampering or unauthorized disassembly
Use in non-approved devices
Covered: where the discharge meter detects less than 70 % of available capacity, or where the voltage is abnormal and the battery cannot be charged — subject to the exclusions above.
Note that an eligible battery defect will be repaired or replaced without extending the original warranty period, and battery replacement does not qualify for cash reimbursement.

Owner manual maintenance requirements
Reproduced from the CEMOTO owner manual:
Battery — Use only the included battery. If it has been discontinued, replace it immediately with the recommended battery supplied with the electric motorcycle.
Battery charger — Use only the included battery charger. If it is out of service, replace it immediately with the recommended charger supplied with the motorcycle.
Wheels — Wheels and drive system components age or wear normally. It is the user's responsibility to systematically check the wheels for excessive wear and to properly adjust and replace drive system components if necessary.
Spare parts — Most common spare parts are available through our distributors.
Additional requirements from the manual:
Adjust the brakes frequently and change the brake pads in time.
Check the chain tightness. Slack should be about 15 mm.
Check the air pressure frequently. Low pressure increases resistance and reduces range.
The electrical elements can only be cleaned on the outside. Do not open them yourself — opening them voids the warranty on those parts.
Do not overload the bike. Electrical parts will be damaged; plastic parts may deform from high temperature and the fuse socket may be damaged by heat. These are not under warranty.
Cut off the power if there is a problem with the electrical parts.
For safety, cut the power supply when the bike is not in use.
The fastening torque of the fixing screw for the rear rack should be 16 N·m.

Tires, Wheels & Suspension
Tire pressure, wheel inspection and suspension setup for CEMOTO bikes.
Tire pressure
Check air pressure frequently. The owner manual is explicit: if the air pressure is too low, resistance increases and the riding range is reduced.
Why pressure matters
Pressure
Effect
Too low
Increased rolling resistance (shorter range); risk of rim damage and pinch flats; vague, unstable steering; increased tire heat
Correct
Best balance of grip, comfort and efficiency
Too high
Reduced grip, especially on loose off-road surfaces; harsh ride; increased puncture risk from sharp edges
Inflating correctly
Use a hand pump with an integrated pressure gauge and a Schrader-type valve.
Do not use a pressurized gas-station air system. Those are designed for car tires at much higher pressure and capacity than a bike tire requires, and can over-inflate or damage the tire.
Tires are shipped at maximum PSI for transport and may lose pressure between production and delivery — always check before the first ride.
Off-road pressure tuning
The D-series runs knobby off-road tires. Lower pressures improve traction on soft terrain but increase pinch-flat risk:
Surface
Tendency
Soft sand, mud, loose gravel
Lower pressure for a larger contact patch and better float
Hard-packed trail, rock
Higher pressure to protect the rim and improve steering precision
Tarmac or sealed surface
Higher pressure for efficiency and lower rolling resistance
Caution: pressures below the tire manufacturer's minimum risk rim damage and pinch flats on a heavy electric dirt bike. Do not go below the sidewall minimum.
Tire wear and replacement
Wear indicator
Action
Knobs rounded or flattened
Grip has dropped significantly — replace
Center tread worn away
Replace
Sidewall cracking
Replace — a safety risk
Cuts or exposed cords
Replace immediately
Repeated punctures
Inspect for embedded debris; replace if the casing is compromised
Tires and inner tubes are wear components excluded from warranty, but are available as replacement parts — see Spare Parts & Compatibility.
Tire options
CEMOTO supplies street tires for the D-series as an accessory, alongside the standard knobby off-road fitment:
Tread type
Best for
Knobby (standard)
Dirt, mud, loose and soft terrain
Street tire
Hard-packed surfaces; lower noise and rolling resistance; longer tread life
Mixed-surface
A compromise where a rider needs both
Confirm the correct size for your model before ordering. D-series sizes: 14"/12" (D02 Classic, D03 Pro) and 17"/14" (D02 Track, D03 Beast).
Wheel inspection
Check
What to look for
Trueness
Lift the wheel and spin it. Side-to-side wobble indicates a buckled rim or uneven spokes
Spoke tension
Squeeze adjacent spokes — they should feel similar. A loose spoke produces a dull tone
Rim condition
Dents, cracks, flat spots
Bearings
With the wheel off the ground, feel for roughness, grinding or lateral play
Axles
Secure, correct torque, wheel spins freely
Hub
No cracks around spoke holes
Wheels and drive systems wear normally. It is the rider's responsibility to systematically check the wheels for excessive wear and to adjust or replace drive system components as needed.
Suspension
CEMOTO D-series bikes have full front and rear suspension — front fork and rear shock. The 72V performance models use pro off-road suspension front and rear. Suspension is what keeps the tires on the ground, which matters more for usable traction than peak power.
Front fork
Check
Detail
Travel
Compress the fork and confirm it moves smoothly through its range
Oil leakage
A ring of oil on the fork tube indicates a failed seal — service required
Pitting or scratches
Damaged stanchions tear seals; they must be replaced
Fork length (D02 Track)
29.53 in (75 cm)
Rear shock
Check
Detail
Mounting bolts
Secure and correctly torqued
Oil leakage
A failed shock loses damping and can bottom out
Bushing play
Lift the rear of the bike and check for lateral play
Spring preload
Adjust to rider weight so the shock sits in the correct part of its travel
Setting sag for your weight
Sag is how far the suspension compresses under the rider's static weight. It should sit in a moderate part of the total travel — enough that the suspension can extend over dips as well as compress over bumps.
To measure:
Lift the rear of the bike until the suspension is fully extended. Measure from the axle to a fixed point on the frame.
Sit on the bike in riding position with both feet on the pegs. Have a helper measure again.
The difference is the sag. Adjust spring preload to bring the sag into the recommended range for your weight.
If the sag cannot be set correctly within the preload range, a spring rate change is needed — this is a specialist job.
Suspension maintenance
Interval
Action
Before every ride
Visual check for leaks and damage; check that the travel is smooth
After off-road rides
Clean mud from the fork wipers and shock; wipe the stanchions
Monthly
Check mounting bolts; check for oil weeping
Every 6 months
Consider a fork and shock service — oil and seals degrade with use
Annually
Full suspension service
Do not use a pressure washer on fork seals, shock seals or bearings. High-pressure water drives grit and moisture past the seals.

D-Series Specifications

Torque & Fastener Reference
Correct torque prevents two opposite failures: fasteners working loose, and components being crushed or cracked by overtightening.
Always use a calibrated torque wrench for safety-critical fasteners — axles, stem bolts, brake calipers and suspension mounts.

General tightening guidance
Fastener size
Typical application
Guidance
M4
Lever clamps, small brackets, plastics
Light — these thread into aluminum or plastics and strip easily. Firm by hand plus a short wrench
M5
Fender screws, number plate, panels
Firm, not forceful
M6
Handlebar clamps, brake calipers, disc bolts
Firm with a standard-length wrench. A cross pattern where there are multiple bolts
M8
Stem bolts, larger brackets
Firm with a longer wrench; use a cross pattern
Axle nuts
Wheel axles
Firm. The wheel must spin freely with no lateral play, and must not shift under braking or drive load
Suspension mounts
Shock and fork mounts
Follow the component guidance; these carry high loads
Tightening technique
Clean the threads and remove any grit. Debris in a thread causes false torque readings.
Apply the correct lubricant or threadlocker if specified. Never apply threadlocker to a nylon-insert self-locking nut.
Start fasteners by hand to avoid cross-threading.
Bring multiple bolts up gradually in a cross (diagonal) pattern. Fully tightening one bolt first distorts the component.
Use a torque wrench for the final pass on safety-critical fasteners.
Never reuse a self-locking nut whose locking feature has worn, or a bolt that has stretched.
Safety-critical fasteners
These fasteners should be checked after assembly, after the first ride, and at every service:
Fastener
Consequence of failure
Front axle
Wheel detachment — loss of control
Rear axle
Wheel shift, chain tension loss, possible rear wheel lock
Handlebar stem and clamp bolts
Bars rotate or detach — loss of control
Brake caliper mounting bolts
Brake loss
Brake lever clamp
Inability to brake
Suspension mounting bolts
Structural failure
Pedal spindles
Pedal detachment and crank damage
Motor mounting bolts
Motor movement, chain misalignment, phase wire damage
Re-check after the first ride
Components seat and settle during the first 20–30 minutes of riding. Re-check every fastener above after your first ride — this is the single highest-value maintenance action on a new bike.
Threadlocker and lubricant guidance
Application
Recommendation
Brake caliper bolts, stem bolts, suspension mounts
Medium-strength threadlocker is commonly used. Apply to clean, degreased threads
Axle nuts with nylon insert
No threadlocker. Replace the nut when the insert loses grip
Pedal threads
Light grease. Never threadlocker — pedals must be removable
Seat post
Light grease on the post, not on the clamp bolt
General bolts into aluminum
Anti-seize if the bike is ridden in wet or salty conditions
Inspecting for loose fasteners
A fastener check takes a few minutes and catches most emerging problems. Look for:
Witness marks. Paint flaking or a bright ring around a bolt head indicates movement.
Thread wear. A bolt that requires noticeably less torque to tighten is stretching — replace it.
Corrosion. Rust on a structural fastener reduces its strength.
Missing hardware. Nuts and bolts lost on the trail should be replaced before the next ride, not after.
Elongated holes. A bolt hole that has become oval indicates the joint has been moving — the component may need replacement.

Cleaning & Storage
How to wash a CEMOTO electric bike or dirt bike without damaging it, and how to prepare it for storage.
Cleaning
The golden rule
Clean the exterior only. The owner manual is specific: the electric elements can only be cleaned on the outside. There is no need to maintain the inside, and do not open them yourself. Opening sealed electrical components voids the warranty on those parts.
What to protect
Component
Why
How
Motor
Water ingress damages windings and bearings
Never direct a jet at the motor or its cable exit
Controller
Sealed electronics; the fins need airflow
Never direct a jet at the controller or its connectors
Battery and charging port
Water in the charging circuit is a fire risk
Cover the charging socket; never wash with the battery port open
Display and connectors
Water in connectors causes corrosion and intermittent faults
Avoid directing water at the cockpit and connector blocks
Bearings (wheel, headset, bottom bracket)
High pressure drives water past seals
Never use a pressure washer
Fork and shock seals
High pressure drives grit into the seals
Never use a pressure washer
Brake discs and pads
Contamination reduces braking and causes noise
Avoid soaps and oils on braking surfaces
Recommended method
Let the bike cool. Do not wash a hot motor or hot brakes.
Remove the battery if your model allows, and cover the battery compartment and charging socket. If the battery is not removable, keep water away from the charging port.
Rinse with low pressure, using a garden hose without a high-pressure nozzle. Work from the top down.
Wash with a mild detergent and a soft brush or sponge. Use a separate brush for the drivetrain, which is greasy.
Clean the drivetrain with a dedicated degreaser and a stiff brush. Rinse thoroughly, then re-lubricate the chain while it is still slightly damp so the lubricant penetrates the rollers.
Clean the controller fins of mud so they can dissipate heat. Use a soft brush.
Dry with a soft cloth and allow the bike to air-dry fully before riding.
Wipe the fork stanchions and shock shaft clean to protect the seals.
Check the brakes after washing. A short, gentle braking session warms and dries the discs.
What not to do
Do not use a pressure washer. It is the single most damaging cleaning tool for a bike.
Do not use solvents, degreasers or aggressive chemicals on painted surfaces, plastics or the display.
Do not aim water at electrical connectors, the motor, the controller, the display, bearings or seals.
Do not wash with the battery charging port open or the socket damp.
Do not submerge any part of the bike. Never ride through deep water, and never submerge the motorcycle — electrical and drive components may be damaged.
Do not open sealed electrical components to clean inside.
After wet-weather riding
Even if there is no mud, wet-weather riding leaves moisture in the drivetrain and connectors.
Wipe the bike down and dry the chain.
Lubricate the chain — this is the most important action after a wet ride.
Check electrical connectors for water ingress; disconnect and reseat them if in doubt.
Test the brakes and all lights before the next ride.
Storage
Short-term storage (days to a few weeks)
Action
Clean and dry the bike
Leave the battery at roughly 40–70 % charge
Turn the power switch off
Store in a dry location, out of direct sun, away from freezing
Avoid leaving a fully charged pack in a hot environment
Long-term storage (weeks to months)
Step
Detail
1. Clean thoroughly
Dirt left on the bike attracts moisture and causes corrosion. Clean, then dry completely
2. Protect the drivetrain
Lubricate the chain generously
3. Set the battery charge
Charge to approximately 50 %. A full charge stresses the cells over time; a flat pack can permanently lose capacity or latch the BMS protection
4. Disconnect the battery
Remove it if the model allows, or disconnect it so it cannot slowly discharge. Even switched off, some systems draw a small parasitic current
5. Store the battery correctly
In a dry location within the recommended temperature range — approximately 68 °F (20 °C) to 45 °F (7 °C). Never store frozen or at extremely high temperatures; extreme temperatures will permanently damage the battery
6. Reduce tire pressure slightly
Particularly in freezing conditions, where a fully inflated tire is more vulnerable
7. Protect from corrosion
Apply a protective spray to metal surfaces if the storage location is damp. Lubricate cables
8. Cover the bike
Use a breathable cover. Avoid plastic sheeting that traps condensation
9. Do not rest the bike on flat tires
Support it so the tires are not taking the full weight in one spot if stored for months
Bringing the bike out of storage
Inspect the full bike for corrosion, fluid leaks, cracks and pest damage.
Bring the battery to room temperature before charging.
Fully charge the battery.
Check and correct the tire pressure.
Check the chain tension and lubricate the chain.
Check the brakes — lever feel, pad thickness and free movement.
Test the throttle, lights, horn and display.
Check all fasteners — axles, stem, calipers, pedals.
Complete the Pre-Ride Inspection before riding.
Ride gently for the first few minutes and re-check after the first ride.

Warning reminders
From the CEMOTO owner manual:
AVOID riding in the rain for long periods of time.
AVOID water contact to the motor and electrical lines.
NEVER ride through deep water.
ALWAYS use caution when going through puddles.
Submerging the motorcycle in water can damage electrical and drive components.
Also note: never touch the motor or brakes immediately after use. These parts get very hot and can burn skin. Allow them to cool before cleaning or servicing.

Notes
Reading the table: a falling range combined with a shorter charge time usually means reduced capacity — the pack is accepting less energy. Compare against the published range figures with your own weight, terrain and temperature in mind. See Battery Care & Charging.
