Please note: CEMOTO currently publishes a single shared owner manual covering the D-series (D02 and D03). It is listed on the store as separate D02 and D03 entries, and both files cover the same D-series content: safety and prevention, assembly, start and run, display, fault display, settings, maintenance, troubleshooting and warranty.

The D-series manual is an illustrated 28-page document. Because the pages are image-based, the text below summarizes its contents so you can search it.

Model Manual
B57A (folding eBike) CEMOTO B57A User Manual (PDF)
EM11 CEMOTO EM11 User Manual (PDF)

The B57A manual is titled Electric Bike B09A-750 internally and covers the shared CEMOTO folding eBike platform: purpose and benefit of the booklet, pre-ride knowledge, assembly instructions, operation, battery and charger guidance, maintenance and safety warnings.

What the D-Series manual covers

The official D-series owner manual is organized into ten sections:

Section Contents
1. Safety and prevention Warnings, rider usage, cycling apparel for safety, precautions for a safe ride, battery handling, forbidden roads, overload, inclement weather, operating parts under high temperature, minimizing risk
2. Assembly Handlebar stem, front number plate, front brake pump and throttle handle, handlebar assembly, front fender, front wheel, tire inflation, front brake pump, rear shock absorber, battery removal, charging
3. Start and run Pre-departure inspection and guidance, start-up methods
4. Display Velocity, battery indicator, mileage (single trip distance DIS, total mileage ODO)
5. Fault display Vehicle status codes and their meanings
6. Settings P01–P17 parameter reference and button combinations
7. Key usage Short press, long press and combined key operations, multi-function display area
8. Maintenance Battery, battery charger, wheels, spare parts
9. Troubleshooting Symptom / possible cause / solution tables
10. Warranty Exclusions, component warranty periods and limitations

Sections 2, 4, 5, 6 and 9 are reproduced and expanded in this documentation center:

Reading the manual on an image-based PDF

The D-series PDF is a scanned/illustrated document, so text search and copy-paste do not work reliably. Two practical options:

  1. Use this documentation center, which reproduces the text content in searchable form.
  2. Use the assembly and technical videos — see Technical Guides.

Which model do I have?

CEMOTO's eBike line is sold under several overlapping naming conventions. The table below maps the store listing to the name printed on the product.

Some models can be set higher through the display's speed-limit parameter — the P-Setting Guide covers this. A higher setting may take the bike outside the Class 2 definition, with consequences for where it may legally be ridden, and for insurance. See Riding Laws & Compliance.

eBikes vs. D-series dirt bikes

These are different product categories with different rules.

eBikes (this section) D-series dirt bikes
Intended use On-road and improved trail Off-road, private land and closed tracks only
Legal status (US) Designed to Class 2 limits Not street-legal
Pedals Yes — throttle + pedal assist No — footpegs and twist throttle
License/registration Generally not required for compliant Class 2 use Varies; often requires registration and a license for off-road vehicle use
Helmet Strongly recommended; required by law in many jurisdictions Mandatory

Do not assume that guidance written for one category applies to the other. In particular, D-series dirt bikes must not be ridden on public roads.

Safety fundamentals

The B57A owner manual — which covers the shared CEMOTO eBike platform — sets out the baseline rules that apply across the whole eBike range:

Before every ride, check the bike, brakes, tires and screws/nuts for tightness.

Who should not ride: young children, pregnant women, and anyone with vision, balance or other problems that would prevent them from riding a bicycle. eBikes are single-rider vehicles — only one person at a time.

Intended terrain: eBikes are for on-road or improved-trail use only and should not be used for riding rough trails. Damage may occur if used off road.

Alcohol and drugs: do not operate the electric bike after consuming any amount of alcohol or taking any drugs.

Helmets: the manual specifies that the correct helmet should be comfortable to the rider, lightweight, well ventilated, fit snugly, and cover the forehead. Learn and observe all road rules for the area where you ride, including always wearing an approved helmet.

Chain tension: approximately 15 mm of slack. To adjust, loosen the rear axle nuts, adjust the chain tightness screw until slack is correct, then tighten the rear axle screw.

Wet-weather braking: in rain or snow, braking distance increases. At 20 km/h the wet braking distance should not exceed 15 m. Adjust the brakes frequently and replace brake pads in time.

Electrical elements: the electric components can only be cleaned on the outside. There is no need to maintain the inside — and opening them voids the warranty on those parts.

CEMOTO AEB31A — City Commuter eBike

A versatile step-thru city commuter eBike with a low-step frame for easy mounting, built for effortless urban mobility.

Product page: cemotoride.com/products/aeb31-city-commuter-e-bikes

AEB31A — View 1

Overview

The CEMOTO AEB31A is a step-thru commuter eBike aimed at everyday urban transport. Its defining feature is the low-step frame, which makes mounting and dismounting easy — particularly useful in stop-start traffic, in normal clothing, and for riders with limited hip flexibility.

CEMOTO describes it as combining a low-step frame with a reliable motor and comfortable geometry, delivering a smooth, efficient and enjoyable daily ride.

Available colors

The AEB31A is listed as a single-variant product. Color options are not published on the store listing.

For current pricing and availability, see the CEMOTO store listing.

Specifications

Detailed specifications are not available for this model. CEMOTO's store listing for the AEB31A does not publish a specification table — motor rating, battery capacity, top speed, tire size, brake type, weight and carton dimensions are not stated for this model, and they are not documented here.

Numbers from other CEMOTO eBike models do not carry over: the range uses 500W and 750W motors, 13Ah / 15Ah / 15.6Ah packs, and 26" and 27.5" wheels depending on model.

If you need the specifications for an AEB31A, contact support@cemotoride.com with your order number and CEMOTO will provide them. See Contact & Support.

CEMOTO B28 (EB28) — 27.5" Electric Mountain Bike

A 27.5-inch electric mountain bike with a 500W motor, 48V 13Ah battery and alloy suspension fork, built for stability and manoeuvrability on steep hills and rocky paths.

Product page: cemotoride.com/products/cemoto-eb28a-emountain-bike

B28 — Main view

Overview

The CEMOTO B28 — sold on the store under the handle cemoto-eb28a-emountain-bike and titled CEMOTO EBIKE B28 — is the 27.5-inch mountain eBike in the CEMOTO range.

Its 27.5-inch wheels are a deliberate middle ground: larger than 26-inch wheels for better rollover and stability, smaller than 29-inch for quicker handling in tight terrain. CEMOTO describes the result as a blend of stability and manoeuvrability that makes it easy to tackle steep hills and rocky paths.

The 500W brushless motor is the lowest-rated motor in the CEMOTO eBike line, paired here with a 48V 13Ah pack — the smallest battery in the range. The design brief is a comfortable, capable all-rounder rather than a maximum-power machine: CEMOTO emphasizes rider comfort, an ergonomic frame, adjustable suspension, and confident grip on descents and sharp turns.

Naming note: this model is listed as B28 in the product title and page heading, but the store URL and handle use EB28A. Both refer to the same bike. It is a different model from the B28A (high-step fat tire) and the B28D (26" folding fat tire) — check the tire size and frame style to be sure which you have.

Available colors

The B28 is listed as a single-variant product. Color options are not published on the store listing.

What it is for

CEMOTO positions the B28 for riders who want trail capability and daily-commute practicality in one bike:

B28 B28A B28D
Wheels 27 × 2.35 26 × 4.0 (fat) 26 × 4.0 (fat)

Frame 6061 alloy 6061 alloy, high step 6061 alloy, folding
Brakes Disc Hydraulic disc (XOD) Hydraulic disc (XOD)

Choose the B28 for efficiency and lighter weight; choose a fat-tire model for sand, snow, loose gravel and a softer ride.

Range and performance notes

Published figures are manufacturer-stated maximums under controlled test conditions (typically a 70 kg rider, 25 °C and 20 km/h constant speed). The 500W motor and 13Ah pack combination means the B28 has the least energy capacity in the CEMOTO eBike range — 48V × 13Ah ≈ 624 Wh. For a structured estimate under your own conditions, see Range Calculator.

The manual's advice applies directly here: to save energy and extend battery life, use pedal assistance when climbing a slope or riding into wind. Low tire pressure increases resistance and reduces range — check air pressure frequently.

CEMOTO B28A (EB28A / AEB28A) — High Step Fat Tire eBike

A high-step fat-tire eBike with a 750W motor, 48V 15.6Ah battery and 26 × 4.0 fat tires — built for all-terrain traction from sand and snow to rough city streets.

Product page: cemotoride.com/products/cemoto-fat-tire-ebike-eb28a

B28A — Main view

Overview

The CEMOTO B28A — sold under the store handle cemoto-fat-tire-eBike-eb28a, titled CEMOTO EBIKE B28A | High Step Fat Tire eBike, and referred to as AEB28A in its own product description — is the high-step fat-tire model in the CEMOTO eBike range.

Its defining feature is the 26 × 4.0 CST fat tire set, which provides vastly more contact patch and air volume than a standard tire. The practical benefits are traction on loose surfaces (sand, snow, gravel, mud) and a much softer ride, because the tire itself absorbs a large share of the vibration that would otherwise reach the rider.

The 750W BLDC motor and 48V 15.6Ah pack are the same core specification used on the B28D and closely related to the EB40, giving the biggest energy capacity in the non-folding section of the range.

CEMOTO rates range at 40–80 miles, a wide band that reflects how much fat-tire efficiency varies with terrain, pressure and rider input.

Naming note: this is the high-step fat-tire model. It differs from the B28 (27.5" mountain, non-fat tires) and the B28D (26" fat tire but with a folding frame).

Available colors

The B28A is listed as a single-variant product. Color options are not published on the store listing.

Feature highlights

Riding a fat-tire bike

Fat tires change how a bike behaves, and it is worth understanding before you ride:

Consideration Effect
Traction Far greater contact patch — excellent on loose surfaces, and it keeps working at low pressures
Tire pressure The single biggest handling variable. Lower pressure increases grip and comfort but raises rolling resistance and reduces range. Check pressure frequently on fat-tire bikes
Rolling resistance Higher than a standard tire. This is why the fat models carry 750W motors and larger batteries
Ride quality The tire volume absorbs vibration that a suspension fork alone cannot, softening rough pavement and trails
Weight and handling Heavier, slower to turn, and more stable at speed. Plan for longer braking distances
Wet braking Braking distance increases in rain or snow — allow more room

CEMOTO's manual advice applies: check air pressure frequently. Too little air increases resistance and reduces range.

Range and performance notes

Range is published as 40–80 miles — a deliberately wide band, because fat-tire efficiency depends heavily on tire pressure, terrain, rider weight and how much you pedal. Published figures are manufacturer-stated maximums under controlled test conditions (typically a 70 kg rider, 25 °C and 20 km/h constant speed).

Use pedal assistance on climbs and into wind to conserve energy and extend battery life. For a structured estimate for your own conditions, see Range Calculator.

CEMOTO B28D (EB28D) — 26" Fat Tire Folding Mountain eBike

A foldable 26-inch fat-tire mountain eBike with a 750W motor (1,500W peak) and 48V 15.6Ah battery — all-terrain capability in a frame that folds for transport and storage.

Product page: cemotoride.com/products/fat-tire-mountain-ebike

B28D — Left view

Overview

The CEMOTO B28D — sold under the store handle fat-tire-mountain-eBike and titled CEMOTO B28D | 26" Fat Tire Mountain eBike All-Terrain Electric Bike; CEMOTO refers to it as EB28D in the product description — is the folding fat-tire model in the eBike range.

It combines the fat-tire formula of the B28A — 26 × 4.0 CST tires, 750W BLDC motor, 48V 15.6Ah battery, hydraulic disc brakes — with a foldable frame. That makes it the practical choice for riders who need to carry the bike in a car boot, store it in a small flat, or take it on public transport.

Its published motor rating is stated as 750W with a 1,500W maximum, which is the highest peak figure quoted anywhere in the CEMOTO eBike line. In practice, the peak rating describes brief acceleration and climbing output, while the 750W continuous rating describes sustained running.

CEMOTO markets it for adventure seekers who want to conquer steep hills and rough trails.

Naming note: the B28A and the B28D share almost identical component specifications. The difference is the frame: B28A is high-step and fixed; B28D folds. If you need a folding bike, this is the one.

Available colors

The B28D is listed as a single-variant product. Color options are not published on the store listing.

For current pricing and availability, see the CEMOTO store listing.

Gross weight (G.W.) 38 kg
Carton size 155 × 27 × 81 cm
Load capacity 120 kg
Wheel size 26 inch

On the two weight figures: the store lists N.W./G.W. as 33 kg / 38 kg on this model, which is internally consistent and matches the net weight of the fixed-frame B28A. Compare with the B28A listing, which publishes 33 kg / 138 kg for the same net weight — the B28D figure is the more plausible of the two.

Feature highlights

Folding bike caveat. Folding frames introduce hinges and a latch — components that need periodic inspection. Before every ride, confirm the frame latch is fully engaged and the safety mechanism (if fitted) is secure, and check the hinge fasteners for looseness. A folding bike's structure differs from a fixed frame, and the weight rating assumes the frame is correctly locked. See Pre-Ride Inspection.

Carrying and storing a folding eBike

Consideration Guidance
Weight At 33 kg net, this is not a bike you will carry far by hand. Fold it to move it, not to walk it
Lifting Lift from the frame, not the handlebars or seat post. Bend your knees — a 33 kg awkward load is a back-injury risk
Latch check Always confirm the frame latch before riding. Never ride with a partially engaged latch
Storage Store folded, dry and out of direct sun. Extreme heat degrades battery cells — see Cleaning & Storage
Transport In a car, lay the folded bike on a mat and secure it so it cannot slide into occupants or the battery cannot be struck
Battery Remove the battery for transport where practical, and carry it separately. See Battery Care & Charging

Range and performance notes

Published figures are manufacturer-stated maximums under controlled test conditions (typically a 70 kg rider, 25 °C and 20 km/h constant speed). The combination of fat tires (higher rolling resistance) and a 48V 15.6Ah pack means real-world range is sensitive to tire pressure — keep the tires correctly inflated, as low pressure increases resistance and reduces range.

Use pedal assistance on climbs and into wind to save energy and extend battery life. For a structured estimate, see Range Calculator.

CEMOTO EB40 — Electric City Commuter Bike

A step-thru urban commuter eBike with a 750W hub motor, 48V 15Ah battery and a full commuter kit including rear rack and fenders — designed to be street-legal at Class 2 limits.

Product page: cemotoride.com/products/cemoto-eb40-electric-city-commuter-bike

EB40 — Main view

Overview

The CEMOTO EB40 is the step-thru city commuter in the CEMOTO eBike range. It pairs a 6061 aluminum alloy frame with a 750W BLDC hub motor and a 48V 15Ah lithium-ion battery, giving a claimed range of 40+ miles.

CEMOTO markets it as Class 2 street legal with a top speed of 20 mph, which places it in the most permissive US category for eBike use on public roads and paths. It ships with a complete commuter kit — rear rack and fenders included — rather than as an add-on purchase.

The step-thru geometry (low-step frame for easy mounting) makes it straightforward to get on and off in traffic and in everyday clothing.

CEMOTO EB66 (B66) — 750W Double Battery Motorcycle-Style eBike

A motorcycle-styled fat-tire eBike with a 750W motor and a choice of one or two 48V 15Ah batteries — iconic cruiser looks with modern electric technology.

Product page: cemotoride.com/products/eb66-harley-like-hi-tech-ebike

EB66 — Main view

Overview

The CEMOTO EB66 — sold under the store handle eb66-harley-like-hi-tech-eBike and referred to internally as B66 — is the styling-led model in the CEMOTO eBike range. It combines motorcycle-cruiser aesthetics with an electric drivetrain: fat tires, a substantial battery, and intelligent controls.

Its standout practical feature is the dual-battery option. The EB66 is sold in two variants — a single-battery version and a double-battery version — which is effectively a factory-fitted range extender. This is unusual in the eBike market, where a second battery is normally an aftermarket purchase, and it makes the EB66 the longest-range option in the range when specified with two packs.

CEMOTO describes it as delivering exceptional performance on city streets and beyond, with a fusion of classic aesthetics and modern engineering.

Naming note: the product image filenames use B66 (B66_1000_720_01.jpg), and the store title uses EB66. Both refer to the same bike. The variant names distinguish the battery configuration.

Available configurations

Variant Battery
48V15AH × 1 One 48V 15Ah pack
48V15AH × 2 Two 48V 15Ah packs

Choosing between them: one pack gives 48V × 15Ah ≈ 720 Wh; two packs give ≈ 1,440 Wh — double the energy, and it materially changes what the bike can do. Note that the second pack adds weight, and the EB66 is already the heaviest eBike in the range at 41 kg net. For current pricing of each configuration, see the EB66 product page.

Key specifications

Measurement Value
Net weight (N.W.) 41 kg
Gross weight (G.W.) 48 kg
Carton size 138 × 28 × 80 cm
Load capacity 120 kg
Wheel size 20 inch

The heaviest eBike in the range. At 41 kg net, the EB66 is 8 kg heavier than the B28A/B28D and 14 kg heavier than the EB40. The dual-battery variant is heavier still. Factor this into storage, lifting and transport decisions — and note that CEMOTO has not published separate weights for the two battery configurations.

Feature highlights

Carbon steel frame — care note

The EB66 is the only CEMOTO eBike using a carbon steel frame. That choice supports the cruiser look, but steel is more vulnerable to corrosion than aluminum, particularly where paint is chipped or scratched.

Practical implications:

See Cleaning & Storage.

Battery and charging

The EB66 uses a 48V 15Ah (≈720 Wh) pack charged by a 54.6V 2A UL-listed charger — the same charger used across the CEMOTO 48V range.

Charging time is not published for the EB66, but by comparison with the B28, which specifies a 6–7 hour charge time on a 48V 13Ah pack with the same 2A charger, expect a similar order of magnitude — likely 7–8 hours per pack from empty. Charging two packs doubles the task unless you have two chargers.

Manual guidance on battery handling:

See Battery Care & Charging for charging practice, storage charge levels and temperature guidance.

Range and performance notes

Published figures are manufacturer-stated maximums under controlled test conditions (typically a 70 kg rider, 25 °C and 20 km/h constant speed). CEMOTO does not publish a specific range figure for the EB66, so range must be estimated from energy content and compared against models with published figures.

EB66 single battery ≈720 Wh Similar to the B28 (624 Wh) and EB40 (720 Wh at 15Ah)
EB66 dual battery ≈1,440 Wh Roughly double the B28A / B28D (≈749 Wh)

The EB66 is heavy (41 kg) with fat tires and a low, wide stance. All three factors consume energy, so expect efficiency below that of a lighter, narrower-tired bike carrying the same charge. Use pedal assistance on climbs and into wind to conserve energy.

For a structured estimate under your own conditions, see Range Calculator.

Performance figures are manufacturer-stated maximums, measured under controlled test conditions (typically a 70 kg rider, 25 °C ambient temperature, 20 km/h constant speed for range). They are not simultaneous guarantees. Actual results vary with rider weight, terrain, temperature, tire pressure, battery condition, riding mode and riding style.

Platform comparison

Compact platform — D02 Classic & D03 Pro

Both models share the same 3000W high-torque motor platform, 48V electrical system and 14"/12" wheel setup. The D03 Pro carries a slightly larger battery (23Ah vs 21Ah), giving it a marginally longer range figure.

The D02 Classic costs less because it removes the horn and some street-oriented hardware, making it the leaner, off-road-first option. If your priority is value and trail fun, it is the D02 Classic. If you want the balanced all-rounder, it is the D03 Pro.

Full-size performance platform — D02 Track & D03 Beast

Both step up to a 72V 25Ah system and a 6000W peak brushless motor, with 17"/14" wheels and a ~32-inch seat height for a taller, more experienced rider.

Frequently asked questions

What is the maximum speed of the CEMOTO D02 Classic? The manufacturer-stated maximum speed is up to 40 mph. Actual speed varies with rider weight, terrain, temperature, tire pressure, battery charge and riding conditions, so 40 mph is not guaranteed.

What is the estimated riding range? The manufacturer-stated maximum range is up to 30 miles per charge. Actual range varies with speed, rider weight, terrain, temperature, tire pressure and riding style.

How long does the D02 Classic take to charge? A full charge takes approximately 6 hours under normal conditions. Use only the compatible supplied charger in a dry, ventilated location and follow the owner's instructions.

What rider height is the D02 Classic designed for? The listed rider-height range is approximately 4'11"–5'10" (150–178 cm), with a seat height of approximately 28.74 inches. Fit also depends on inseam, balance, strength and riding experience.

What is the maximum load? The confirmed maximum load for the D02 Classic is 287 lb. Rider weight, equipment and anything carried on the bike should remain within this limit.

Is the D02 Classic suitable for teen riders? The D02 Classic is marketed for teens and adults who fit the bike. Suitability also depends on maturity, strength, training and experience; adult supervision and appropriate protective gear are recommended for teen riders.

Is the D02 Classic street legal? The D02 Classic is intended for off-road use on suitable private property and tracks. It is not marketed as a street-legal commuter, and riders should check all applicable local laws before use.

Is the D02 Classic less powerful than the D03 Pro? No. Both models use the same 3000W high-torque motor platform. The D02 Classic costs less because it removes the horn and some street-oriented hardware, making it the leaner, off-road-first option.

Does the bike arrive fully assembled? Some assembly and pre-ride checks are required after delivery. An adult should follow the assembly guidance and verify fasteners, brakes, controls, tires and suspension before the first ride.

What is included in the box? The confirmed package includes the D02 Classic bike, one compatible charger, assembly tools and hardware, a manual and the original shipping carton. Exact tool appearance may vary.

Where does the D02 Classic ship from? Dispatch origin, delivery coverage and any shipping cost are set out in the Shipping & Delivery policy. Tracking is provided after shipment.

How long does U.S. delivery usually take? Delivery timing depends on your destination, the carrier and current conditions, and is stated on the Shipping & Delivery policy page rather than fixed here. Track your order with the details supplied after dispatch.

Is a signature required for delivery? Signature requirements depend on the order value and are set out in the Shipping & Delivery policy. Monitor your tracking information and move the package to a secure location promptly after delivery.

What should I do if a component arrives damaged? Photograph the carton, shipping label, internal packaging and affected component, then email support@cemotoride.com to open a ticket. If shipping damage to a component is confirmed, CEMOTO dispatches replacement parts under the Shipping Policy.

Where can I buy replacement parts and get technical help? Compatible parts are available in the CEMOTO accessories collection. Technical guides and video-assisted troubleshooting are available through the Technical Guides library and CEMOTO support.

What warranty and return coverage is included? Warranty period, coverage and exclusions are defined by the Warranty and Warranty Claims pages; the return window and who pays return shipping are defined by Returns & Refunds. Those pages are authoritative — any period quoted in a listing or campaign is superseded by them.

Frequently asked questions

How is the D02 Track different from the D02 Classic? The D02 Track uses the 72V 25Ah / 6000W peak performance platform with 17"/14" wheels and a 31.9-inch seat, while the D02 Classic uses the 48V 21Ah / 3000W platform with 14"/12" wheels and a 28.74-inch seat. The D02 Track also adds a reverse mode and a removable, off-bike-chargeable battery.

Frequently asked questions

What does the 3000W figure mean? It is the stated peak motor output, not a continuous or nominal power rating.

How fast and how far can the D03 Pro go? The manufacturer states up to 40 MPH and up to 34 miles. Actual results vary with rider weight, terrain, temperature, tire pressure, mode selection and riding style.

Who is the D03 Pro designed to fit? The stated rider-height range is approximately 4'11"–5'10", with a 28.3-inch seat. Individual inseam, skill and comfort should also guide fit.

How large and heavy is the shipping carton? The supplied carton dimensions are approximately 51.6 × 12.2 × 24.4 inches. Listed net weight is approximately 121 lb and gross shipping weight is approximately 139 lb, so buyers should plan suitable space and lifting assistance.

Does it include a street kit or qualify for road use? No street kit is included. The D03 Pro is presented for off-road use on suitable private land and tracks, not as a street-legal vehicle.

What speeds do the three modes allow? The bike has three selectable modes, but verified mode-by-mode speed test data is not available, so no specific speed is assigned to each mode.

Is a 30-degree climbing claim included? No. There is no verified standardized test basis for that claim.

How quickly does an in-stock order ship? Dispatch and delivery timing depend on live stock and your destination — see the Shipping & Delivery policy for the current terms.

What warranty is included? The warranty period, coverage and exclusions are governed by the official Warranty terms and the Warranty Claims procedure.
