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.

Amp-hours indicate the electric charge that an electric bike battery can deliver during operation. This measure helps to roughly estimate the motor's operating time, but by itself does not give an accurate understanding of the range because it does not take the battery voltage into account. For example, batteries with 10 Ah at 36 V and 48 V will have different energy reserves, even though the amp-hour value is the same. Therefore, it is convenient to look at 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 shields over the wheels that reduce the splashing of water, dirt, and sand onto clothing, shoes, the frame, and battery compartment. Especially useful for urban commuting, wet asphalt, gravel roads, and daily rides to work, but they add some weight and can rattle if poorly fixed.

— Chain Guard. A protective cover that encloses part of the chain and front sprockets, reducing the risk of soiling or snagging clothing. Particularly suitable for urban e-bikes for rides in regular clothes, though it might hinder quick access to the chain for cleaning, lubrication, or repairs.

— Sprung Saddle. A saddle with a spring suspension unit that cushions shocks and vibrations transferred from the rear wheel to the rider. This option is comfortable for leisurely and city e-bikes, particularly on tiles, cobblestones, and rough asphalt, but for a sports position and active riding, it may be less precise and heavier than a regular saddle.

— Kickstand. A foldable support that allows the e-bike to stand without a wall, rack, or bike parking. Convenient near shops, at home, at the office, or during a short stop en route, but for heavy e-bikes, it's crucial that the kickstand is sturdy and doesn't collapse under the bike's weight with a load.

— Rear Rack.... A rear cargo platform for mounting bags, baskets, panniers, a child seat, or carrying small luggage. Useful for city use, delivery, shopping trips, and tourism, but loading can shift the weight backwards and potentially affect balance, especially if the battery is also mounted on the rack.

— Front Rack / Basket. A front platform or basket located at the handlebars (above the front wheel), intended for carrying a bag, backpack, groceries, and small items. This option is convenient for short urban trips, but heavy loads at the front can impact steering and make the bike less stable at low speeds.

— Horn / Bell. An audible signal helps warn pedestrians, other cyclists, and traffic participants of your approach. For city areas, courtyards, bike paths, and parks, it's a practical safety element, although a regular bell does not replace attentiveness and may be difficult to hear in noisy traffic.

— Headlight and Taillights. The front headlight illuminates the road, while the taillights make the e-bike more noticeable to other traffic participants. This is important for evening rides, tunnels, cloudy weather, and riding along roads.
