Always follow the charging instructions supplied elcykeln, for as long lasting joy and benefit as possible from the batteries. Li-Ion batteries have admittedly småladdas, but it’s always good to run the battery “empty” now and then. However, you should avoid draining the battery completely, because it can damage the battery, so keep track of cycle battery indicator. When it says that the battery is empty, it is time to load it.
For long-term storage of Li-Ion batteries should not be fully charged or discharged, but about 50-70% charged. Due to self-discharge, the battery should be checked and recharged every two months during long-term storage. Many electric bikes comes with the automatic charger, which ensures that the battery has an optimal charging during everyday use. We do not recommend that the charger is in constant during long-term storage. Proper handling and maintenance gives the battery a longer life.
Elcykelbatterier that is “stale” can be submitted in all XXL stores or municipal waste collection.New batteries can be purchased in XXL’s stores, but must be ordered in advance.
Charging the battery’s current state, watt-hours and the charge capacity affect charging time.Standard charging for XXL’s elcykelbatterier with Li-Ion technology is 4-6 hours. If the charger does not automatically stops charging when the battery is fully charged, you must oversee this. All electric bicycles as XXL sell the automatic charger.
When it is cold outside, you should take and recharge the Li-Ion battery indoors, but if the bike is in a heated garage, bike shed or similar battery can be charged while mounted on the bike. If you do not have that option, you may want to choose an electric bicycle where the battery is easy to remove and carry. A elcykelbatteri generally weigh between two and four kilos.
B atteriets weight and placement Logically gives high emphasis on engine and battery, a little less comfort when cycling because the bike gets heavier. But in addition, weight distribution is critical for comfort, that the bike is well balanced. It affects the handling of the bike, and some cheap electric bicycles can be downright unpleasant to ride on, because the structure is not sufficiently balanced.
Some e-bikes are battery integrated in the frame, to get a lower center of gravity. But this is no need to elcykeln should be easy to handle. In several of the most comfortable and balanced elcyklarna, the battery in the carrier, but this has since taken into account in the design process.Good weight distribution, geometry and handling characterizes most expensive electric bikes of high quality, as they are generally more well-designed and thought through.
The engine position Electric Bikes with front-mounted engine is front-wheel drive, which is a less expensive, but well-functioning solution. The engine sits in the front wheel hub, which means that you actually get two-wheel drive, as you are contributing force to the rear wheel and spoke with lights for riding at night. The advantage is that it is very easy to remove and service the engine. An electric bicycle with front-mounted engine feels a little different to ride on, because most traditional bikes are rear-wheel drive. It is e.g. a little harder to run up the asphalt edges, sidewalks and more. This type of engine has often been a little less torque than the other two types, and is therefore best suited to urban environments and flat terrain.
A mid-mounted engine drives directly on the chain and put the weight on the rear wheel. The force is concentrated to the bottom bracket, as they have to transfer power, which provides an effective and constant transmission power is transmitted to the rear wheel via the chain. Rear-wheel drive is perceived as something better uphill and provide a more predictable cycle feeling, because all the traditional bikes are rear-wheel drive. At mid-mounted engines have to switch firmly to harness the power maximum, but this is something you learn pretty quickly. Centre mounted engines often perceived as very powerful.
A rear-mounted engine gives naturally also rear-wheel drive, and is a common solution that provides high comfort. Weight and placement are the same as for a front-mounted engine, but the engine is in place in the hub of the rear wheel. It is a very discreet placement and you do not hear the sound of the engine as much as it is located behind your ears.
Watts = power consumption unit watts (W) you will certainly recognize from eg light bulbs. Watt is the speed at which electric current is consumed with, ie how fast the power runs out. The lower watt / electricity consumption, the more time you have electricity. Volt electric voltage = voltage (V) is the voltage of the battery that supplies power to the electric motor. If you increase the voltage, you also increase the potential for transferring power from the battery to the motor, and from there to the drive wheel. There will always be a small power loss during transmission of power. The voltage at the more expensive electric bicycles are often controlled by an electronic controller, optimizing the tension in relation to the use and load.
E-bikes are usually supplied with 24 or 36 volt battery and motor. 48 V is the maximum battery voltage for electric bicycles in Sweden.
Ampere Hours = battery capacity Ampere hours (Ah) are electricity consumption over time and usually gives a good indication of elcykelns range. The battery capacity of electric bicycles is usually between 7 and 17 Ah. Watt-hours = electricity consumption over time watt-hours indicating battery capacity over time. If you multiply volts and amps hours to get watt-hours. If you have a 36-volt battery of 8.8 Ah, you have the 316.8 watt-hours at your disposal. That means you’ve 316.8 watts for an hour or 1 watt in 316.8 hours, etc. A 36-volt battery with 400 Wh is thus 11.1 Ah. Watt-hours indicates how much power you have at your disposal over time and gives an indication of how much range you actually have. range = how far you will higher voltage / volt and more ampere hours (Ah) actually gives you greater capacity, but the range is dependent on a number of other factors. Uphill / downhill, acceleration, start / stop, user weight, bike weight, surface, tires, aerodynamic drag, exchange, packing and own initiative are examples of things that affect your reach. The latter is crucial.
Low outdoor temperatures also reduces battery capacity, as the battery internal resistance increases. This reduction will in practice it is difficult to say. A simple rule of thumb is that from 20 oC and down, pull the 0.5% effect per degree. At 0 degrees, the battery thus a power reduction of 10% and at -10 ° C, a power reduction of 15%.
In cold reduces the pressure in the tires, resulting in a higher rolling resistance. This can be compensated by filling in little more air in the tires in the winter.
All these factors you must take into account when choosing electric bike, so that you have a certain margin in relation to the desired range.
