10 keys to improve the range of your e-Bike

The range of e-Bikes for the electric motor to assist pedaling depends on the battery charge. So, on the quality and the management that we make of it, the range will depend on it. We’ll tell you how to maximize their range.

The batteries have improved their capacity with new materials, with lithium-ion batteries offering the best quality and performance today. A good brand of electric bikes will have a battery with the maximum guarantees. Some of them, their range can be from 40 to 90 km.

Taking into account a series of factors that we can apply in the routine of use of our e-Bike, we can take full advantage of the range that our lithium battery provides us and increase the range of use with electrical assistance:

  1. Take care of your battery

Batteries work by storing energy and releasing it through the electrolysis process. Current technology, with the use of lithium, has the advantage that the electrolysis process can be repeated up to thousands of cycles, even though the degradation of its cells is inevitable.

The current technology has some drawbacks that we must take into account to be able to extend the useful life of our battery, whose duration must reach five years. It is not true that current batteries require completely depleted in the first cycle before performing the second charge. The BMS (BATTERY MANAGEMENT SYSTEM) found inside modern batteries limits the total charge or discharge and the speed at which they do so to increase the life of the cells, preventing overcharging.

But we must always charge the battery with the charger supplied by the manufacturer and recharge at moderate temperatures, between 10 and 20ºC. And keep the battery at room temperature neither too cold nor too hot.

  1. Watch for the age of the battery

The useful life of a lithium-ion battery does not begin when the cells are manufactured, but the day it receives its first charge, as a result of the chemical reaction of the SEI (Solid Electrolyte Interphase), which produces a layer of oxide of lithium around the graphite anode. Thereafter it continously reduces the minimum load capacity. Manufacturers deliver cells with 60% first-charge cycle in most cases, so you don’t have to worry about buying a new battery that was made quite some time ago.

  1. Appropiate motor power

The 250W motors are the most balanced and suitable and, although there are more powerful ones, they require a higher consumption and do not contribute much more in a current e-Bike. When choosing our e-Bike, performance is an important factor to have an adequate range.

  1. Control the consumption of accessories

The use of electronic devices and accessories on an electric bicycle require energy to function. Some of these are battery powered or carry their own internal battery, but most use the battery. Display, lights, brackets and chargers, anti-theft systems, etc … Together or one by one they reduce the performance of the battery and its range.

  1. Take care of the weight

It is obvious that the greater the overall weight between our body and our e-Bike, the more energy it will take to move. Therefore, it is convenient to load our e-Bike with the essentials, trying to move the least possible weight.

  1. Select the route profile

Either we want to exercise more or less or simply move in the shortest possible time, an e-Bike allows us to adapt the effort to our taste. But even in the city, a route is rarely linear, with constant changes in slope and turns. On slopes, the amount of energy for pedaling will be greater and the requirement for pedaling assistance more frequent. Selecting our route will allow us to take care of the autonomy, more considering that the specifications of any battery are based on standards in neutral inclination for the homologation of the data.

  1. Stop as little as possible

The greatest energy requirement is above all is the one produced in starts. From a standstill, overcoming the resistance represented by the joint weight of the bike with its driver until picking up the pace and the maximum speed of 25 km / h implies a lot of energy, more than we use when we already have inertia.

Therefore, for practical purposes to extend the range of your electric bike, always try to maintain inertia and slow down if possible before a crossing or a traffic light so you don’t stop and give yourself time to go when its green.

  1. Weather conditions

We have already discussed that the temperature affects the duration of the load, either by heat and, above all, by very low temperatures. Protecting our battery, if possible, a cover will help us to prolong its charge.

But another factor is the wind, which can play in our favor or against it. Several studies show that the performance of the batteries drops by up to 20% when we circulate against the wind for a long time, which is transformed to the contrary downwind. In these circumstances we can do little, except reduce speed to oppose less resistance to the wind and seek a more aerodynamic posture without conditioning our safety, always with both hands on the handlebar.

  1. Adequate tire pressure

It is essential to check the tire pressure. For our safety, so that the shoulders maintain their rigidity when leaning in curves and to reduce friction resistance. The manufacturer indicates what is the appropriate pressure, and it is what we must carry on both wheels. A little inflated tire will increase friction, and therefore the effort on the pedals, in addition to deforming the tire if we roll a long time in those conditions.

  1. Fit the components well

Although it may not seem important, it all adds up. For our safety and energy savings, poorly adjusted brakes can cause the pads or shoes to rub on the disc or rim to produce resistance. You won’t notice that mismatch that much on an electric bike if braking is still effective, but unnecessary friction requires more energy. The same if we do not have the wheels well aligned or the suspension has lost its capacity. Everything simply requires good maintenance.
