Warning: The factory setting for maximum speed is 25 km/h to meet the European standard for e-bikes. However, the setting can be manually changed to a higher speed limit. Bear in mind that in such a case the e-bike no longer meets the required standards and cannot be used on public roads!
Note: The expected max. travel distance depends on various factors, such as the amount of electric assistance, user weight, terrain, wind and the inflation pressure, pattern and temperature of the tires. All stated travel distances are valid under optimal conditions, meaning even terrain with no wind, temperature of 20°C, extremely narrow tires with no profile and user weight under 70 kg.

Generally speaking, the more the better. Mountain and cross bikes should have at least 24 speeds (road bikes should have at least 18).
The main part of a bike. Other parts and components are affixed to it. It has a shape of an uneven pentagon, but the main load-bearing part is made up of an uneven quadrangle with an adhering triangle at the rear (unless the bike has rear fork suspension).
Brakes are an essential part of a bike. The two most common types are disc brakes and V-brakes. Disc brakes are more effective, but need to be maintained more often, while V-brakes are easy to maintain and last longer. Other braking systems include drum brakes or a coaster brake (in children's bikes).
Serves to attach the front wheel and brake.

Tires serve to protect the tube inside and they optimize the riding attributes of your bike, both on the road and in terrain. Mountain bike tires are wide and have a complex pattern that allows for movement on difficult terrain. Road bike tires, on the other hand, have a shallow pattern and are thin and smooth.
Tires serve as a protection of the inner tube and optimalize the riding qualities of a bike in terrain and on the road. Mountain bike tires are wide and have complex patterns, allowing for riding through hard terrain. Road bikes on the other hand have thin and smooth tires with only a shallow pattern.
Levers or grip shifters change the revolving ratio in the relation of the front sprocket wheel (crankset) and the rear sprocket wheel (cassette) with the help of the front and rear derailleur.
We come across lever shifts most often, since they usually also feature a precise indicator. Children’s and junior bikes often feature user-friendly grip shifts that don’t need a lot of strength. They are basically a part of the handlebar grips. Different levers are used on road bikes with bullhorn handlebars where they are part of the brake levers and the rider shifts gears by pushing the lever sideways.
Gear shifting on the rear wheel.
Plates and one to three sprocket wheels transfering the pedal movement onto the chain.
On modern bikes, sprocket wheels on the rear wheel are affixed to a cassette. Along with the front derailleur, they add more gears and the rider can choose the optimal speed/pedalling ratio. Cassettes can be taken apart and the sprocket wheels exchanged for others (new or with different number of sprockets).
The chain transfers the pedalling force into the rear wheel. it connects the cassette on the bottom bracket and the cassette on the rear wheel. It needs to be lubricated often.
A metal circle with a U-shaped profile. It creates space for the inner tube and tire. Bikes designed for professional use and therefore more demanding riding style have double-walled rims. Such rims provide higher durability and better safety. Rims for regular bikes are usually made of dural, rims for special bikes can be made of special alloys or composites.

Metal part connecting the pedal to the centre.
Handlebars are connected to the stem and they help steer the bike. They carry braking elvers, gear shifters, grips and accessories, such as a cycling computer, a bell, a map and many others. They come in different shapes, i.e. riser bars, bullhorns or drop bars.
Cover both ends of the handlebar. Their function is to ensure that the handlebar doesn't slip and that it is comfortable to hold.
Connects the front fork with the handlebars. Some types are adjustable.
Tube that connects the frame with the saddle. It's length is adjustable to accomodate users of different heights. These days, it is affixed to the frame with a quick-release mechanism. In the past, a nut and a screw were used.
Front light is white and can have the form of a classic bulb with high energy consumpion or a more expensive diode light. Some models offer several lighting modes. It is compulsory to have a front light under worsened visibility conditions.
The rear light is red and usually uses diodes. Higher level models have several modes, such as constant light, flashing of all diodes or alternating between separate diodes. In worsened visibility conditions, rear light is required by law.
Plastic or metal mudguards for the front and rear wheel. Their purpose is to protect the cyclist against mud and water splashing from the revolving wheel. Mudguards are not often used on mountain bikes (however, there are special mudguards for this purpose), so that the mud glued to the wheels wouldn't rub against them. The front mudguard is attached to the fork, on mountain bikes it can be also attached to the frame. The rear mudguard is affixed to the frame near the centre and to the rear fork under the saddle. On mountain bikes, the rear mudguard is attached under the seat post (approx. 20 cm above the wheel).
