Comparison DYU C6 vs Maxxter City

The maximum weight for which the frame, wheels, suspension, brakes, and other components of the electric bike are designed. This usually implies the weight of the rider along with baggage and accessories: for example, a backpack, basket, child seat, or load on the luggage rack. It is not advisable to exceed this limit, as the additional weight reduces maneuverability, increases braking distance, and accelerates wear on the wheels, spokes, hubs, and frame.

Approximate distance that an electric bike can travel on a single battery charge. Specifications usually indicate an estimated value, as the actual range depends on the chosen level of assistance, rider's weight, terrain, speed, temperature, and tire pressure. For example, in economy mode, an e-bike can travel significantly further than when constantly riding with maximum support and speed downhill.

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.

The braking mechanism on the front wheel, which is responsible for a significant portion of the bike's deceleration. For an e-bike, this component is particularly important due to the higher weight and speed: on descents, wet asphalt, dirt, and during sudden stops, the type of brake affects not only comfort but also safety.

— Rim. The pads are pressed against the wheel rim and slow down the bike through friction. This brake is simple, lightweight, and inexpensive to maintain, but performs poorly in rain, mud, and under heavy load, making it more suitable for calm city riding and budget models.

— Mechanical disc. Brake pads clamp the disc on the hub of the wheel, and the force from the handle is transmitted via a cable. Compared to rim brakes, the disc brake performs more reliably on wet roads and is better suited for heavy e-bikes, but requires periodic adjustment of the cable and pads.

— Hydraulic disc. The force from the handle is transmitted to the brake caliper through hydraulic fluid. This brake generally provides the most powerful and precise stopping, making it well-suited for mountain e-bikes, fat bikes, descents, high speeds, and riding with loads, but it is more expensive and complex to maintain.

— Roller. An enclosed hub brake where deceleration occurs inside a special mechanism with rollers. It is well-protected from dirt and rain, requires infrequent adjustments, and is convenient for...city bikes, but is less powerful than disc brakes during active riding and long descents.

— Drum. The braking mechanism is located inside the hub, where the pads press against the inner surface of the drum. This design is protected from moisture and contamination, durable, and low-maintenance, but typically heavier and less effective in sharp stops compared to disc systems.

The braking mechanism on the rear wheel, which helps control speed, stabilize the bicycle, and safely modulate deceleration. On an electric bike, it is especially important when riding downhill, on rough terrain, wet roads, and with additional load, although the main braking force is usually on the front wheel. — Rim. Pads press against the rim of the rear wheel and slow the bike down through friction. This brake is simple, lightweight, and inexpensive to maintain, but performs worse in rain, mud, and when the rim is worn, so it is better suited for calm city rides. — Mechanical disc. Pads clamp the brake disc on the rear wheel, and the force from the handle is transmitted by a cable. This is a more stable option for an electric bike than a rim brake: it handles moisture and dirt better but requires periodic adjustment of the cable and pad position. — Hydraulic disc. The brake disc is clamped by a caliper, and the force is transferred through hydraulic fluid. This rear brake is well-modulated, requires less effort on the handle, and is suitable for heavy e-bikes, mountain routes, fat bikes, descents, and active riding. — Roller. A closed hub brake, with a mechanism containing rollers located inside the housing. It is protected from dirt and rain, requires almost no attention in daily use, and is convenient for city models, but is less powerful than disc brakes during sharp deceleration and extended descents. — Drum. Pads work inside a drum in the hub of the rear wheel. T...his design is durable, protected from the environment, and suitable for leisurely rides, but usually heavier and less effective at intensive braking than the disc system. — Coaster. Braking is activated by pedaling backward, and the mechanism is usually located in the rear hub. This is a simple and dirt-protected solution for city and leisure bikes, but it is less suitable for high-speed electric bikes, steep descents, and situations requiring precise modulation of braking force.

The number of gears indicates how many mechanical shifts are available to the rider for changing the pedaling effort. Simple transmissions with a small number of gears may suffice for city e-bikes, while a wider range of gears is more convenient for hills, long routes, off-road terrain, and riding without active motor assistance. However, a large number of gears does not always mean a faster e-bike: it primarily affects the convenience of riding in different conditions, not the maximum speed of the electric motor.

This point should not be confused with the motor speed modes: gears change the operation of the chain and sprockets, while modes change the level of assistance from the electric drive.

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.

The operating voltage of the battery system, for which the motor, controller, charger, and electronics of the e-bike are designed. 36V systems are more commonly found in city, recreational, and moderately powerful models, while 48V is typically used where stronger climbing power, dynamic acceleration, or riding with a load is needed. When replacing the battery, the voltage must comply with the bike's standard system; otherwise, the electronics may function incorrectly or fail.

— 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.

— Bottle Holder. A frame-mounted holder for a water bottle allows you to keep water handy during a ride. It's useful for long routes, training, summer riding, and tourism, but on some e-bikes, space for a bottle may be limited by the battery, low frame, or non-standard geometry.
