Comparison Maxxter City 2.0 vs DYU C6

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 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.

— Aluminum. An aluminum frame is lighter than a steel one, resistant to corrosion, and well-suited for most city, mountain, folding, and touring electric bicycles. It is the most versatile option in terms of weight, strength, and cost, though aluminum might feel harsher on rough roads, especially without good suspension.

— Steel. A steel frame is characterized by high strength, repairability, and a softer feel on bumps. It is suitable for city, leisure, cargo, and utility electric bicycles where reliability and load capacity are crucial. Drawbacks include heavier weight and the need for corrosion protection, especially when riding in rain, mud, or winter conditions.

— Magnesium alloy. A magnesium alloy frame is lighter than steel and can be lighter than some aluminum structures, and is often used in cast frames of folding and city e-bikes. This material allows for neat, solid shapes and reduces bike weight but is usually more expensive, less common, and requires high-quality corrosion protection coating.

— Carbon fiber. A carbon fiber frame is made from carbon composite and allows for reducing bike weight while maintaining high structural rigidity. This material is more often used in expensive sports, road, gravel, and advanced mountain e-bikes, where lightness and ride efficiency are essential. However, carbon is more costly, more sensitive to point impacts, and more challenging to repair after damage.
