Trek’s electric bikes

The Trek electric bicycle brand is established in a highly competitive market. However, in spite of a discreet insertion on this last one, it imposes itself today as a reference in the field of the cycling. So, whether you prefer road or city bikes, there is bound to be a bike from the American group that suits you.

Electrically assisted bicycles are a means of transportation that is often confused with conventional electric bicycles. However, there are profound differences between these machines. For example, the electric bike has an intelligent motor, which is not the case with other electric bikes.

On the other hand, the electric motor starts as soon as you turn the pedals, while on electric bikes, the motor can start without the driver touching the pedals. This “start and stop” function, with which electric bikes are equipped, means that they can cover a longer distance. That said, at peak speeds, the electric bike will go faster because of its motor.

Weight and size

If you want to buy your Trek electric bike, you should know that you can get it in any size you like. In fact, the seatpost, handlebars and stem are available in S, M, L and XL. To make the best choice, we have made a listing of these according to the size of the rider:

In addition, there is a user-friendly Purion Bosch control system. This allows you to consult all the information related to your driving and the assistance of your means of locomotion.

Comfort and safety

The engine armor is an exclusive shield because it is both light and strong. In this way, the motor remains inaccessible to the trunks, stones and various debris that it meets on the road.

The Trek electric bicycle already contains an internal cable ready to use for the addition of additional lights. To benefit from them, you just have to buy them from a dealer, then attach them to the bike and plug them in. To improve the practical aspects of the Trek electric bicycle, the manufacturer has reinforced several elements.

In order to achieve absolute flexibility and control of the bike, the brand went through a series of tests until it found the right diameter for the right frame size. Each sophisticated tube is made by hydroforming.

This is how the American group obtained a minimal weight for a maximum of solidity. Moreover, the RockShox Recon RL fork allows a 120 mm travel.

Prices and aids

Buying a Trek electric bike means getting out of the low-end category. Indeed, on this bike, each part has been thought to make your mountain electric bike more efficient while keeping a really unique style. To buy your Trek Powerfly 5, you should budget around 3999,00 euros.

However, the price of your bike can be reduced thanks to financial aid. In some European Union countries, like France for example, the state grants a subsidy of 200 euros, if you already benefit from a subsidy at the local level. To be eligible, you must meet certain conditions:

The insurance

For this means of locomotion, no specific insurance is required. Indeed, the electric assistance stops as soon as the speed of 25 km/h is reached. However, in order to avoid paying costs in case of damage to a third party, we advise you to take out a civil liability insurance.
