Our selection of E-Bikes is only from renowned manufacturers, who of course also provide all the necessary spare parts for the electric drive. The selection is wide, but before you go to choose a suitable e-bike, read this article, which will guide you in choosing the right one for your needs. It's not enough to decide whether you want a mountain or cross e-bike, it is also necessary to choose the type and brand of electric drive.
E-bikes have already found their place on the market and their sales are growing rapidly year-on-year. They are a solution for people who, for various reasons, need the help of an electric motor. In many cases, these are women who, by nature, do not have as much physical strength as men and, with the help of an electric drive, are able to handle the same portions of miles as their partners. Another group is the elderly, for whom the electric bike represents an opportunity to get further and thus explore a larger area while riding without exhausting themselves. At the same time, they can serve well as a means of transport, e.g. on the way to work when the cyclist does something for his health but at the same time does not come to work with no energy left. Recently, a larger group of such cyclists has been profiling themselves, who, even though they are in good condition, buy an electric bicycle because they want to see more, go further, and enjoy cycling in general.
The use of electric bicycles is regulated by law. The maximum engine power is limited to 250 watts, and the weight of the bike must not exceed 40 kg. If the e-bike has an auxiliary accelerator that allows the bike to start without pedalling, then the maximum allowed speed for starting is limited to 6 km/h. While pedalling, the maximum speed allowed is up to 25 km/h. The basis of the e-bicycle is either a classic bicycle, supplemented by an electric kit, or a bicycle with a special frame and a motor and battery holder for the purpose of combining an electric motor. When converting a conventional bicycle to an electric bicycle, it must be said that conventional bicycles are not designed for an auxiliary motor, where higher forces act on the bicycle frame, which are also directed in a different way, which can result in the destruction of the bicycle. Especially when using various non-certified electrical kits, which are offered on the Internet and whose power exceeds 1kW. The electric bicycle set also includes an electronic measuring unit, a pedal sensor, a control unit on the handlebars, connecting cables and usually a modified battery carrier, unless there is a specially adapted frame for them.
Different batteries
Batteries are the one of the most important and also most discussed part of every e-bike. The range depends on them. Old lead-acid batteries are a thing of the past, even though they still appear on cheap bicycles. We divide modern batteries into: 1.NiMH - Nickel metal hybrid - they can be charged quickly, they have a lifespan of up to 500 charging cycles. They can be stored in a charged or discharged state and can be refurbished. They have twice the capacity of NiCd batteries. 2. Li-Ion - Lithium-ion - have a higher capacity and especially low weight with a long life of up to 1000 charging cycles. They hardly discharge, but age faster at higher temperatures. 3. Li-Pol - Lithium polymer - are the best in terms of performance/life/weight, but they are the most demanding for accurate charging, therefore a special charger is required for them. 4. LiFePO4 - Lithium iron phosphate - are more affordable, have excellent thermal stability and can absorb and release energy faster. However, they have a lower internal memory and their lifespan fluctuates when charged quickly. Their development is still underway.
The batteries are placed in different places on the bike depending on the category of the bike, it is often found on the bicycle carrier, which can harm the center of gravity of the bicycle. Recent years, manufacturers have been trying to place the battery along the seat tube of the frame, either in front of or behind it. For frames with a standard frame shape as well as an upper frame tube, its full integration in the lower frame tube has been gradually used since 2017, so that the battery is not visible at all. The advantage is the maximum reduced center of gravity of the bicycle, but at the price of a slightly higher weight of the bicycle. At the same time, it is necessary to take into account that the battery is best charged directly on the bicycle, its removal is more complicated and in some design solutions it is even necessary to dismantle several components first.
