As a general rule of thumb, you should always read reviews about the e-bike and its components before buying it to ensure you don’t pay too much.

E-Contrail Expert components
Fork
The Marzocchi Bomber Z2 is included from the factory. It has a travel distance of 130mm. Bike forks are good shock absorbers and provide a smooth ride and a great experience. In conclusion, always look for a fork with decent travel when you buy a bike.
Rear Shock
From the factory, it comes with the RockShox Deluxe Select rear shock model, which has a travel of 130mm. Bike rear shocks increase the riding comfort, and also give you more control over technical trails. In conclusion, to increase your riding experience, get a bike with a rear shock if possible.
Wheels size
When leaving the production line, the E-Contrail Expert model has 29″ aluminum wheels. Having 29″ wheels means that you need less fork travel, leading to a reduction of the pedal bob effect. However, 29″ wheels will make your e-bike react slower to obstacles you may encounter.
Brakes
For your safety, it is important to have quality breaks on your bike. Bergamont E-Contrail Expert has Hydraulic Disc brakes installed. Hydraulic disc brakes provide amazing stopping power, no matter what the terrain. To sum up, your safety is in good hands.
