Electric Bikes & Scooters Electric Bikes & Scooters Documentation for CEMOTO commuter, mountain, fat-tire and folding eBikes, plus the EM11 three-wheel scooter. 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. Store listing Also known as Category cemoto-eb40-electric-city-commuter-bike EB40 Step-thru city commuter aeb31-city-commuter-eBikes AEB31A Step-thru city commuter cemoto-eb28a-emountain-bike B28 / EB28 27.5" mountain eBike cemoto-fat-tire-eBike-eb28a B28A / AEB28A / EB28A High-step fat-tire eBike fat-tire-mountain-eBike B28D / EB28D 26" folding fat-tire mountain eBike eb66-harley-like-hi-tech-eBike EB66 / B66 Motorcycle-styled fat-tire eBike — B57A Folding eBike (manual only) — EM11 Three-wheel scooter (manual only) Why the naming is confusing: the same physical bike appears in the store under a marketing name (EB40, EB66) and in internal/manual naming (B28A, AEB28A). Where the manuals use a different designation from the store listing, this documentation notes both. Model line-up Tap a model to open its full specification page.

Every CEMOTO eBike ships configured to a 20 mph maximum, the U.S. Class 2 limit. 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. Shared platform characteristics Most CEMOTO eBikes share a common component set: Drivetrain — SHIMANO 7-speed derailleur gearing. Charger — 54.6V 2A, UL-listed, which is the correct charger for a 48V (13S) lithium pack. Frame — 6061 aluminum alloy on most models (the EB66 uses carbon steel). Load capacity — 120 kg on every model with a published rating. Display — color LCD, 4 inch, on most models. Fork — alloy suspension, "Lo" travel designation.

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. NEVER carry a passenger on the electric bike. NEVER modify the electric bike with unapproved accessories. NEVER ride through deep water. NEVER perform wheelies, jumps or trick stunts. AVOID riding in the rain for long periods of time. AVOID water contact with the motor and electric lines. ALWAYS keep both hands on the handlebars. ALWAYS apply brakes lightly when riding on rocks or loose surfaces. ALWAYS use caution when going through puddles. ALWAYS inspect the electric bike before each ride to ensure a safe ride. 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.

Product page: cemotoride.com/products/aeb31-city-commuter-e-bikes 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 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. For current pricing and availability, see the CEMOTO store listing.

Plan carefully for long off-pavement rides; see Range Calculator Beginners and experienced riders — CEMOTO markets it as an excellent choice for both Comparison with the other fat-tire models B28 B28A B28D Wheels 27 × 2.35 26 × 4.0 (fat) 26 × 4.0 (fat) Motor 500W 750W 750W (1,500W max) Battery 48V 13Ah 48V 15.6Ah 48V 15.6Ah 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. Safety and legal notes Wear an approved helmet and observe all road rules for the area where you ride. Confirm your local eBike rules. See Riding Laws & Compliance. eBikes are single-rider vehicles. Never carry a passenger. Intended terrain: eBikes are for on-road or improved-trail use. Avoid riding rough trails — damage may occur. Learn the trail rules and stay within the bike's limits. Do not ride through deep water, and avoid prolonged riding in rain. When riding in bad weather, braking distance increases. Chain tension should be about 15 mm. See Drive & Transmission. Images B28 — official product photography.

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

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. Safety and legal notes Wear an approved helmet and observe all road rules for the area where you ride. Confirm your local eBike rules — a 750W motor with a potentially higher configured speed may sit above the Class 2 definition in some jurisdictions. See Riding Laws & Compliance. eBikes are single-rider vehicles. Never carry a passenger. Intended terrain: on-road and improved trail. Do not ride rough trails — damage may occur. Do not ride through deep water, and avoid prolonged riding in rain. Chain tension should be about 15 mm. Braking distance increases in bad weather. Ride accordingly.

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 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. Key specifications Specification Value Motor 750W BLDC (1,500W max) Battery 48V 15.6Ah Li-ion Charger 54.6V 2A, UL-listed Display Color display, 4 inch Frame 6061 aluminum alloy, folding Fork Alloy suspension (Lo) Brakes Hydraulic disc (XOD) Tires 26 × 4.0 CST (fat tire) Gears SHIMANO 7-speed Max speed 20 mph Load capacity 120 kg Peak motor output 1,500W Sizes and weight Measurement Value Net weight (N.W.) 33 kg 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 Foldable frame — the defining feature. Makes the bike carriable in a vehicle boot, storable in tight spaces, and easier to take on trains, boats and campervans 750W motor with 1,500W peak — the highest quoted peak output in the CEMOTO eBike range, for steep hills and quick acceleration 48V 15.6Ah battery — the larger pack used across the 750W models, providing substantial range 26 × 4.0 fat tires — all-terrain traction on sand, snow, gravel and mud, with a naturally cushioned ride Hydraulic disc brakes (XOD) — strong, consistent stopping power for a heavy, high-traction bike Alloy suspension fork — absorbs impacts alongside the tire volume 6061 aluminum alloy frame — keeps weight manageable despite the folding mechanism and fat tires SHIMANO 7-speed gearing — pedal efficiently and conserve battery when you want to 4-inch color LCD — clear speed, battery and trip readout 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. Safety and legal notes Wear an approved helmet and observe all road rules for the area where you ride. Confirm your local eBike rules — the 1,500W peak rating is well above the Class 2 motor definition in many jurisdictions. See Riding Laws & Compliance. eBikes are single-rider vehicles. Never carry a passenger. Intended terrain: on-road and improved trail. Do not ride rough trails — damage may occur. Do not ride through deep water, and avoid prolonged riding in rain.

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 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. Available colors Color White Black For current pricing and availability, see the EB40 product page.

CEMOTO's range tests typically assume a 70 kg rider, 25 °C ambient temperature and 20 km/h constant speed. Real-world results vary with rider weight, terrain, temperature, tire pressure, battery condition and riding style. For a structured way to estimate range for your own conditions, see Range Calculator. Safety and legal notes Wear an approved helmet. Required by law in many jurisdictions for eBike riders. Confirm your local eBike rules. Class 2 compliance applies in many US states, but local ordinances on where eBikes may be ridden (paths, trails, sidewalks) vary. See Riding Laws & Compliance. eBikes are single-rider vehicles. Never carry a passenger. Improve your range by pedalling.

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 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 Specification Value Motor 750W BLDC Battery 48V 15Ah Li-ion × 1 or × 2 Charger 54.6V 2A, UL-listed Display Color display, 4 inch Frame Carbon steel Fork Alloy suspension (Lo) Brakes Disc, Tektro Tires 20 × 4.0 KENDA (fat tire) Gears SHIMANO 7-speed Max speed 20 mph Load capacity 120 kg Sizes and weight 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 Motorcycle-inspired design — cruiser styling, a defining attribute of this model Dual-battery option — up to ≈1,440 Wh of onboard energy for extended range 750W BLDC motor — strong output to move a heavy, fat-tired machine 20 × 4.0 KENDA fat tires — the smallest-diameter fat tires in the range, giving a low stance, a compact footprint and excellent traction Tektro disc brakes — a recognized brake brand, providing consistent stopping power Carbon steel frame — chosen for the cruiser aesthetic. Heavier than the 6061 alloy used elsewhere, and it needs more diligent corrosion care Alloy suspension fork — absorbs impacts alongside the fat tires SHIMANO 7-speed gearing — lets you pedal efficiently and conserve battery Fat tires for superior traction — CEMOTO cites traction as a core EB66 benefit Intelligent controls and a 4-inch color display — clear readout while riding 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: Dry and inspect the frame after wet rides, and after any exposure to salt (winter roads, coastal air). Touch up paint chips promptly to prevent rust spreading. Pay attention to the underside of the frame, welds and the area around fasteners, where water collects. Do not use a high-pressure washer. Water forced into seams and bearings causes more harm than the dirt it removes. 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: Recharge before your first ride and after any long-distance operation. Use only the battery supplied with, or recommended for, the bike. Use only the supplied charger. If it fails, replace it with the recommended charger — not a generic substitute. For safety, cut the power supply when the bike is not in use. Battery lifespan averages 1 to 2 years depending on usage and conditions. Plan for replacement. Never leave a battery charging unattended for long periods, and charge on a non-flammable surface away from anything combustible. 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. Configuration Energy Comparison 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. Safety and legal notes Wear an approved helmet and observe all road rules for the area where you ride. Confirm your local eBike rules. A 750W motor with high energy capacity may sit above local eBike definitions — in some jurisdictions, higher-power, throttle-operated bikes are classified differently from pedal-assist eBikes, with consequences for licensing, insurance and where you may ride. See Riding Laws & Compliance. eBikes are single-rider vehicles. Never carry a passenger, regardless of the cruiser styling and apparent seating room. Intended terrain: on-road and improved trail. Do not ride rough trails — damage may occur. Do not ride through deep water, and avoid prolonged riding in rain. The steel frame and the electrical system both warrant particular care here. Chain tension should be about 15 mm. Braking distance increases in bad weather, and this is a heavy bike — allow generous stopping distance. Mind the weight. 41 kg is difficult to lift safely. Use proper technique and consider a second person for loading into vehicles. Images EB66 — official product photography.
