More about autonomy

How many kilometers can I travel with my electric bike? This is the big question we ask ourselves when we want to buy an electric bike, and the answer is complex because it depends on many factors. The first and primary factor regarding the range of a fully charged battery is the energy stored in it, which we quantify in watt-hours (Wh). We obtain this by multiplying the battery's volts (V) by its ampere-hours (Ah). For example, a 48V 13Ah battery has 624Wh of energy when fully charged, and a 36V 16Ah battery has 576Wh of energy. Once we understand the concept of energy, we need to consider the motor's power, which will determine the consumption of this energy. A bike for legal use in the EU can have a motor with a maximum nominal power of 250W, but it doesn't consume the same amount when working at its limit on a slope greater than 20% (it can have peak consumptions of nearly 150% of its nominal power) as it does when used calmly on flat terrain. Having understood this, we can also say that it doesn't help if the cyclist on a 20% incline uses a low assistance level and does most of the work pedaling, while the cyclist on flat terrain uses a high assistance level and makes no effort, leaving all the work to the motor. This factor, which is obviously key to range, can be joined by other factors that have a lesser influence, such as the cyclist's weight, position, pedaling cadence, and the number of starts and stops, since starts cause consumption peaks. The type of terrain (hilly or flat), 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 precise and reliable information about a bike's range. The information we provide about the range of our products is for a person weighing 75kg with normal bike use. For example, mountain bikes with combined use on paths with ascents and descents, and urban bikes with city trips involving many stop-start cycles. We don't advertise maximum ranges, but real ones, tested without aiming for especially low consumption. We have achieved ranges of over 200km by seeking maximum efficiency, but we understand that it would be dishonest to advertise these as the normal use of resources was not typical. We can only add that the aspect that sets Moma electric bikes apart from the competition is precisely the range. 100% of professionals who have tested them have been impressed with this data. For us, it is essential in this type of vehicle, and we work daily to improve it as much as possible with batteries that have a high energy storage capacity and very efficient motors that consume the least energy possible.

The feature that distinguishes a Longtail from other bicycles is its rear section. It has an extra-long luggage rack integrated into the frame, which supports a maximum weight of 80kg. You can install the following on it:
- 2 child seats
- 2 cushions if they no longer need seats
- 1 seat + 1 cushion
Alternatively, you can install a box, allowing you to use the bike as a means of transportation for delivering goods.
It also has a front luggage rack-basket, which supports a maximum weight of 15kg.
And if that wasn't enough, in the center of the frame, there is a bag with a capacity of 7.5 liters, ideal for storing any item such as a phone, wallet, or even a small backpack.

The child seats and the large capacity rear box shown in the photographs are not included.
