For a comfortable and calm ride, many have a need for electric bikes. And for those who want to test the adrenaline, the manufacturer produces two-wheeled cars with high speed capabilities and power.
Features
Cars are considered powerful electric bikes from 1000 and more watts. The convenience of the vehicle is combined with an electric motor or pedal drive and the ability to use them both combined and separately. Such dynamism will allow the vehicle to be a bicycle in the park and a scooter on the road.
To save battery, you can use physical activity, for which the pedals are used. Today, the rated speed that an electric bike can develop is between 50-115 km / h. In addition to the rear and front, there are also models with all-wheel drive. Electric bicycles are not able to reach high speed; they cannot be compared with a solid car in design.
The main feature that attracts fans of this type of transport is the possibility of acceleration to an impressive speed.
The advantages of electric bicycles:
- great dynamics;
- large power reserve from the battery;
- excellent overcoming of hilly terrain by electric motor;
- excellent speed characteristics;
- positive emotions from the ride.
Features when choosing
Most people, when choosing a powerful electric bike, pay attention to the battery capacity, which is one of the important components, since a high battery requires a good battery. Power is determined by the characteristic of the engine, which the 48V battery must withstand.
Battery and power are important factors, but you should pay attention to the type of frame, wheel size and shock absorption.
Types of batteries
There are several types of batteries.
- Lead acid (cheap, obsolete, slow when charging and requiring frequent replacement).
- Lithium ion (manganese and polymer, capacious and durable). High resistance does not allow them to be installed on powerful electric bikes.
- Lithium iron phosphate. The most advanced at the moment due to the long service life and the ability to withstand low temperatures. Fire is minimized.
Lithium-polymer are considered the most dangerous when they are hit, overheated or at low temperatures. Ionic - less dangerous, but still have negative properties. Lithium iron phosphate have the safest components, are not afraid of low and high temperatures. If damaged, do not catch fire.
Types of engines
There are 3 main types of engines:
- chain, belt (transmission of torque from the engine to the frame);
- friction (transmission of torque from the motor shaft to the rear tire);
- carriage (carried out by acting on the axis of the pedals).
In 90% of cases, a carriage is installed (a wheel connected to a motor). It is attached to the front or rear wheel, while a small number of moving elements are used, which allow to give greater efficiency at low energy costs. This type of engine is quiet and extremely reliable, since all mechanisms are inside the case, which prevents external influences.
On powerful electric bikes, the drive is mounted on the rear axle, for better traction and riding in the snow, dirt, rugged, hilly terrain.
For off-road and active, fast driving, they prefer huge torque. At the same time, the cost of transport increases several times.
The lineup
Black trail
The 2015 model has excellent speed characteristics and high cost. Over the development of this luxury item were attracted 20 German designers who spent a year and a half. The model combines modern and retro style.
Velobike develops a decent speed of 100 km / h with a weight of 20 kg. Lightness and strength deserves carbon fiber and the aluminum alloy of which the frame consists.
Each bicycle frame is handcrafted and assembled at a factory in Germany.
The steering column is equipped with touch switches, a brake and gas handle. Some parts are composed of magnesium and titanium. The lithium-ion battery has 48V power and is located in a leather case. Full charge takes 3 hours.
The engine has a hybrid structure, with a power of 3.6 kilowatts. When driving at a speed of 40 km / h, a distance of 200 km is covered. Its cost ranges from 80,000 dollars. This is a limited version.
Gulas pi1s
Today is The fastest pedal-driven electric bike. Acceleration is carried out using an electric power plant with a capacity of 38 liters. with. and allows you to reach speeds of up to 115 km / h. It has a weight close to the motorcycle, 128 kg. Equipped with a telescopic fork, stiffer suspension, horizontal rear shock and a 17-inch wheel diameter. Torque - 100 Nm.
The package features a battery capacity of 6.5 kWh and 10 kWh. In the first case, you can drive up to 125 km, and in the second - up to 200. The price varies from 23 to 34 thousand dollars. The downside is the lack of pedal and engine sharing. Aerodynamics do not allow for sharp turns.
E-bike Operation
Before starting the movement, make sure that the mechanical parts are correctly assembled. It checks the operation of the power supply of the electric drive and the presence of a charge indicator on the display, the condition of the brake pads, the correct operation of the wheels, the battery and the drive.
Should be carried out regularly:
- chain cleaning and lubrication;
- bearing lubrication;
- brake check;
- tire pressure;
- state of stars;
- reliability of puffs of threaded connections.
Movement should be started using the pedals (if possible combined use), pushing your feet off the ground.
In another case, we use the drive. When driving, smoothly turn the throttle and adjust the speed mode. At first use, sharp bends and high speeds should not be resorted to to avoid personal injury. Traffic rules are an integral part of the knowledge that must be applied when driving on electric bicycles.
At a speed of more than 60 km / h, overtaking cars, one should understand the risks and the possibility of emergency situations. Therefore, drivers with a motor power of more than 250 W are required to have the category "M" (moped) in rights. An electric bike with a powerful engine and a capacious battery is an excellent, almost silent means of transportation, ready to provide the owner with maximum comfort and dynamism on any stretch of road.
