Comparison Haibike Seet HardNine 3.0 2018 frame S vs Haibike Seet HardNine 3.0 2017 frame S

The year to which the manufacturer classifies the bicycle (more precisely, the model range that includes this model).

The significance of this parameter is that the model range is updated every year, and two bicycles with the same name, but from different years, can differ significantly in characteristics and equipment. At the same time, new models ( 2024, 2023) usually cost more, and older ones ( 2022, 2021, etc.) are sold at reduced prices.

It is worth considering that a later year of manufacture in itself does not necessarily mean more advanced characteristics - manufacturers can change them in the direction of simplification. So the model of previous years may be in no way inferior to the new bike.

Tyre model supplied with the bike as standard. Different tyres have different purposes and characteristics; knowing the tyre model, you can clarify these points and check how they correspond to your wishes. This is especially important when choosing a machine for serious cycling.

The model of the hub used in the front wheel of a bicycle.

The hub is the central part in the wheel through which the axis of rotation passes. Features of the behavior of a bicycle depend on its characteristics, in particular, “rolling” (the ability to move by inertia, without pedaling). Knowing the model of the front hub, you can clarify its characteristics according to the manufacturer's documentation, find reviews from other users, etc., in order to determine how this model suits you.

Model of the hub used in the rear wheel of a bicycle. See Front Hub Model for details.

Model of the derailleur (derailer) installed on the carriage with pedals as standard on the bike. For more information on why you need to know the model of a particular bicycle component, see paragraph "Cassette Model".

Model of the derailleur (derailer) installed on the rear wheel cassette as standard on the bike. For more information on why you need to know the model of a particular bicycle component, see paragraph "Cassette Model".

The model of the shifters (see “Shifter type”) that are fitted to the bike as standard. For more information on why you need to know the model of a particular bicycle component, see paragraph "Cassette Model".

Features of the handlebar stem (see " Stem Adjustment ") installed on the bike. Here, both the offset model and its individual characteristics, most often the length and diameter, can be indicated. The stem itself can be either a separate part or an integral part of the steering wheel itself (the so-called integrated stem); the latter option is convenient in that the steering wheel cannot be skewed (unless broken), respectively, there is no need for centering.

As for the parameters, the rider’s landing depends on the length — the longer the takeaway, the more you will have to lean forward (ceteris paribus); strength and resistance to loads are directly related to the diameter; See “Cassette Model” for details on why the model name may be needed. It is worth noting that these parameters are important primarily for keen enthusiasts who pay attention to the smallest details in the characteristics of the machine; for most users, even advanced ones, such trifles are unlikely to be useful.
