Comparison Fiido M1 Pro vs Kugoo T01

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.

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.

Folding design allows for reducing the size of the e-bike due to the hinge in the frame, foldable handlebars, or other movable components. This format is particularly convenient for the city, home storage, transportation in an elevator, car trunk, or "bike + transport" trips. When choosing, you should consider not only the fact of folding but also the weight of the e-bike, its folded dimensions, and the reliability of the locks, as play in the hinges can worsen the feeling of rigidity while riding.

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.

The maximum speed at which an electric bike can accelerate using the electric motor. For relaxed city rides and bike paths, models with a limit of around 25 km/h are usually sufficient, while options with speeds of approximately 30–35 km/h are found for suburban routes and more dynamic riding. Higher speeds are more common in powerful off-road bikes, fat bikes, and high-speed models.

It is worth considering that the actual speed depends on the motor's power, rider's weight, battery charge, terrain, wind, and controller settings. In some cases, it may also be limited by traffic regulations or firmware.

The type of front fork describes the internal construction: how the unit compresses upon impact and how it absorbs rebound. In e-bikes, this aspect is essential not only for comfort but also for handling on rough terrains, as the heavy e-bike places more stress on the suspension.

— Spring-elastomer. A metal spring is used inside, with an elastomer that helps soften impacts and limit sharp vibrations. This is a simple and affordable solution for city rides, leisurely outings, and light off-road, but it lacks the smoothness and adjustability of oil systems, and the elastomer may become stiffer in cold conditions.

— Spring-oil. Elasticity is provided by a metal spring, while oil dampens oscillations and makes the suspension operation more controllable. This option is heavier than the air-oil type but generally more reliable and stable than the spring-elastomer version, making it suitable for versatile e-bikes, poor roads, off-road, and moderately active riding.

— Air-oil. In this suspension, air acts as the elastic element, while oil ensures smooth operation and damping of oscillations. It is lighter and can be more precisely adjusted to the rider's weight using air pressure, making it well-suited for mountain, trail, and more advanced e-bikes, but usually costs more and requires more attentive maintenance.

The type of rear suspension describes the design of the rear shock absorber of the electric bicycle: how the element compresses during impact and how effectively it dampens the frame oscillation. This parameter is important for full-suspension bikes, fat bikes, and models for rough roads, as the rear shock absorber affects saddle comfort, rear wheel traction, and bike behavior on uneven surfaces.

— Spring-elastomer. Uses a metal spring and an elastomer insert inside to help absorb shocks. It's a simple and inexpensive solution for city and light trail electric bikes, but it’s less smooth, adjustable, and stable compared to more advanced oil systems.

— Spring-oil. A metal spring takes the compression, while oil dampens excessive oscillation after impact. This suspension is usually more reliable and stable than spring-elastomer types, suitable for broken asphalt, dirt roads, and moderate off-roading but heavier than air variants.

— Air. The elastic element is an air chamber, and the pressure can be adjusted according to the user's weight and riding style. This rear suspension is lighter than spring types and convenient for precise adjustment, often found in more advanced e-bikes, although it requires pressure monitoring and more careful maintenance.

— Air-oil. In this rear suspension, air acts as the elastic element, while oil ensures smooth compression and controlled rebound. It can be finely adjusted for rider weight, active riding,...trails, and mountain routes, but it is usually more expensive and requires regular maintenance.

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.
