Comparison ADO A20+ 360Wh vs ADO A20F+ 375Wh

Type of Electric Bicycle — a structural class of model that defines the seating position, frame geometry, wheels, suspension, and main purpose of the bike.

— Mountain (MTB). An electric bicycle for rough terrain, dirt roads, forest trails, and moderate off-road conditions. It usually has a strong frame, wide tires, a suspension fork, or full suspension, and the motor helps to climb hills and navigate difficult sections of the route more easily.

— Downhill / freeride / enduro. Reinforced mountain e-bikes for aggressive riding, steep descents, rocks, roots, jumps, and complex trails. These models often feature powerful brakes, long-travel suspension, and robust frames but are heavier, more expensive, and less practical for regular city rides.

— Trail. A versatile type of mountain electric bicycle for forest trails, hilly terrain, dirt roads, and moderately difficult descents. Compared to a regular MTB, it is often better prepared for active trail riding, and compared to enduro or downhill models, it remains lighter, more practical, and more convenient for everyday routes.

— Urban. A model for daily city rides, bike lanes, and smooth asphalt. For this type, comfortable seating, fenders, a luggage rack, lighting, a kickstand, and convenience are more important than maximum passability or sports speed.

— Road. An electric bicycle for riding on asphalt, in parks, along...embankments, and on suburban roads. In essence, it is closer to a universal bike for smooth surfaces: faster and lighter than an urban bike but usually not as sporty and demanding in terms of seating as a road bike.

— Touring. A bike for long trips, cycling journeys, and routes with baggage. It is usually designed for stability, comfortable seating, range, and mounts for racks, bags, and fenders, making it well-suited for trips outside the city and multi-day routes.

— Cruiser. A comfortable electric bicycle with a relaxed seating position, wide handlebars, and a design for leisurely rides. This type is convenient for strolling, resort areas, and smooth city routes but not intended for a fast pace, steep climbs, or sporty handling.

— Road bike. A lightweight high-speed e-bike for asphalt, long distances, and sports riding. It usually has narrow tires, aerodynamic seating, and a minimal set of extra equipment, with electric assistance used not for “moped” riding but to maintain pace on climbs and long routes.

— Gravel. An electric bicycle for mixed routes: asphalt, dirt roads, packed forest roads, and light off-road. It is faster and sportier than a touring bike but more stable and versatile than a road bike thanks to wider tires, baggage mounts, and a relaxed geometry.

— Fatbike. An electric bicycle with very wide tires for sand, snow, loose terrain, and rough roads. The large tires provide good passability and absorb bumps, but they increase weight and rolling resistance, so the motor is particularly useful here.

The range of recommended height indicates for which user the electric bike will be comfortable in terms of fit, handling, and frame height. Unlike the dry frame size markings like 17″, 19″, 52 cm, or M/L, this point is simpler for the buyer: it immediately suggests whether the model will fit a person with a height, for example, of 165, 175, or 185 cm.

Preset levels of electric drive operation that change speed limits, acceleration intensity, and motor assistance degree. Simple models may have 2–3 modes for relaxed, normal, and dynamic riding, while more advanced ones offer multiple assistance levels with more precise settings for city, suburban, uphill, or long-distance routes.

Do not confuse this feature with mechanical gears: speed mode controls the motor's operation, while gears change the effort on the pedals.

Ampere-hours indicate the electric charge that an e-bike battery can deliver during operation. This value helps roughly estimate how long the motor can be powered, but on its own it does not provide an accurate understanding of the range, because it does not take the battery voltage into account. For example, 10 Ah batteries at 36 V and 48 V will have different energy reserves, even though their ampere-hour rating is the same. Therefore, it is useful to consider Ah together with voltage and capacity in Wh.

Watt-hours indicate the total energy reserve of the battery and are more suitable for comparing the range of different electric bicycles. This measure takes into account both the capacity in amp-hours and the system voltage: for example, a 36V battery with 10Ah has about 360Wh, while a 48V battery with 10Ah has about 480Wh. The higher the Wh value, the greater the potential range, but the actual distance still depends on the rider's weight, motor power, terrain, speed, assistance mode, and temperature.

The charging time indicates how long the e-bike battery must be connected to the charger for a full recharge. The greater the battery capacity in Wh or Ah, the longer it typically takes to charge with a standard adapter. For daily urban trips, it's important not only to consider the maximum range but also whether the battery can be fully charged overnight, between trips, or before heading out on a long ride.

— Fenders. Protective guards above the wheels that reduce water, dirt, and sand splashing onto clothing, footwear, the frame, and the battery compartment. Especially useful for city rides, wet asphalt, dirt roads, and daily commuting, but they add a little weight and may rattle if loosely mounted.

— Chain guard. A protective cover that shields part of the chain and front sprockets, reducing the risk of getting clothing dirty or caught. It is especially suitable for city e-bikes used with regular clothing, but may hinder quick access to the chain for cleaning, lubrication, or repairs.

— Spring saddle. A saddle with a spring suspension mechanism softens impacts and vibrations transmitted from the rear wheel to the rider. This option is comfortable for recreational and city e-bikes, especially on tiles, cobblestones, and rough asphalt, but may be less precise and heavier than a regular saddle for a sporty riding position and active riding.

— Kickstand. A folding support that allows the e-bike to stand without a wall, stand, or bike rack. It is convenient near a store, home, office, or during a short stop along the route, but on heavy e-bikes, it is important that the kickstand is sturdy and does not fold under the weight of the loaded bike.

— Rear rack. A rear car...go platform for mounting bags, baskets, top cases, a child seat, or carrying small luggage. It is useful for city riding, delivery, shopping trips, and touring, but when loaded, it shifts weight backward and may worsen balance, especially if the battery is also mounted on the rear rack.

— Front rack / basket. A front platform or basket near the handlebars (above the front wheel) designed for carrying a bag, backpack, groceries, and small items. This option is convenient for short city rides, but a heavy load at the front may affect steering and make the bike less stable at low speed.

— Horn / bell. An audible signal helps warn pedestrians, other cyclists, and road users of your approach. It is a practical safety feature for the city, courtyards, bike paths, and parks, although a regular bell does not replace attentiveness and may be difficult to hear in heavy traffic.

— Headlight and position lights. The front headlight illuminates the road, while position lights make the e-bike more visible to other road users. This is important for evening rides, tunnels, overcast weather, and riding alongside roads.
