E-road 28 pro electric bike

¿How many km can I travel with my electric bicycle This is the big question we ask ourselves when we want to buy an electric bicycle and the answer is complex, since it depends on many factors. The first and main factor regarding the autonomy of a fully charged battery is the energy stored in it, which we quantify in watt hours (Wh) and obtain by multiplying the battery's volts (V) by the ampere hours ( Ah), for example, a 48V13Ah battery has a fully charged energy of 624Wh and a 36V16Ah battery has an energy of 576Wh. Once we are clear about the concept of energy, we have to see the power of the engine, which is what will determine the consumption of this energy. A bicycle for legal use in the EU may have a motor with a maximum nominal power of 250W, but it does not consume the same when working at the limit of its capacity on an incline of more than 20% (it may have peak consumption of close to 150% of its nominal power) than when we use it quietly in a place without slopes. Once this is understood, we can also say that it is of no use to us if the cyclist who climbs 20% does so at a low level of assistance and he does most of the work by pedaling and the cyclist who goes on the flat place, goes with a high level of assistance and does not make any effort, leaving all the work to the motor. To this factor, which is obviously key in autonomy, we can add that factors such as the weight of the cyclist, their position, their pedaling cadence and the times it starts and stops since consumption peaks are caused during startups. The type of terrain (hill or flat), the surfaces (asphalt or road) and even the wind (headwind) and the type and geometry of the tire also have consequences. For all these reasons, it is very difficult to provide accurate and reliable information about the range of the bicycle. The information we provide about the autonomy of our products is for a 75kg person with normal use of the bicycle, that is, mountain bikes with a combined use of roads with ups and downs, urban bikes with city trips with quite a few cycles. starting and stopping, etc. We do not advertise maximum autonomy, but real autonomy with tests without seeking especially low consumption. We have managed to obtain ranges of more than 200km seeking maximum efficiency, but we understand that it would be dishonest to advertise them since the use of resources was not normal. We can only add that the aspect that highlights moma electric bicycles over those of the competition is precisely the autonomy, 100% of professionals who have tried them have been impressed with this data, for us it is essential in this type of vehicle and we work day by day to improve it as much as possible with batteries with a lot of energy storage capacity and very efficient motors that consume as little energy as possible.e.
