* Note 1: remaining range is just a reference. Figures shown are based on riding in "normal" mode.
Actual remaining range depends on selected mode ("ECO" or "normal"), weather conditions, riding style,
selected gears, etc. See section 5.1.6: "Range".
** Note 2: also charging time is just a reference. Actual charging time depends on the age of the battery and
the number of times it has been charged / discharged. Longer charging time may be necessary for older
batteries.

5.1.6 Range

The range is the distance you can cycle using power assistance on one charge. This depends on many
different factors that can be divided into 2 groups:
Capacity and condition of the battery
The cycling circumstances and the state of the bicycle.
A summary of matters that have direct influence on the distance that you can ride:
1. Age of the battery: when the battery gets older, its capacity becomes less. So, with a brand new, well
charged battery you can ride a larger distance than with a battery that is 1 year old.
2. Number of battery charges: the riding range decreases after a number of battery recharges. Partly this
can be compensated by "refresh charging"
3. The temperature: the performance of the battery depends on the temperature. When it's colder, the
battery's capacity is reduced, so you cannot reach the maximum distance with your Lafree.
4. The wind: easy to understand that, when you ride with strong head wind, the Lafree uses more energy
than without wind, so the reach becomes shorter.
5. The terrain (flat, steep hills, slopes, pavement):
pavement, the engine uses more energy than on flat or smooth roads.
6. Rider's weight and luggage: for a light rider without additional luggage is less energy required than for a
heavy rider or a rider that carries luggage.
7. The number of stops and starts: riding in heavy traffic or in the city with lots of traffic lights means that
you have to make much more stops and starts compared with riding in the countryside. Because of the
energy consumed during acceleration, the riding range becomes shorter when the number of stops and
starts increases.
8. Clever use of gears: energy (form the rider, but also from the battery) will be saved if the gears on the
bike are used in the correct way. Especially accelerating and riding uphill should be done in low gears, in
the same way as driving a car. Start riding in 1st gear and, when speed increases, shift to 2nd and 3rd
gear. This helps you to save energy and to increase the range.
9. Quality and state of bicycle components, such as
- tyres with too low pressure or well inflated tyres.
- a dirty, corroded, dry chain or a clean and well lubricated chain.
Poor maintenance increases the resistance and the extra energy required empties your battery quicker.
