   Good, Affordable alternative to on-brand bikes!

   9 people found this helpfulThe good:The build of the bike is really sturdy and I really believe that it will stand the test of time. It has a solid construction and the folding mechanics work perfectly.It’s beautiful. If you want an eye catching bike, this is a good purchase, the blue and white makes this bike stand out anywhere on the road and with a custom LED touch, it gets even better!It’s super stable. The ride is smooth and stable thanks to the fat tires.The bad:When I got it, it needed a tune up fairly bad. My guess is because it travelled across seas from China. So, take it to a shop to get it all tuned up.The max speed I could clock was 16.9 mph with just the throttle. That is plenty of speed for most bike trails and with pedaling you can get it up to 25, but it does take significant effort. I never saw 30mph even with the most effort I could put in.

   Best electric bike out there!

   This electric bike is awesome, fun and easy to use! I bought this bike for my teenage son, who loves going mountain bike riding, going to the beach and playing in the snow in the winter. That’s why I decided to go for this bike for him, because it seems to be able to handle any type of weather or terrain. He absolutely loves it! He says what he likes most is that if he wants to go to the beach and go mountain biking all in the same day, he can. He can pedal the bike in normal bike mode and then use the electric function when he needs a little extra help, like a tall hill or soft beach sand. It has altogether three modes to choose from, pedal assist and full electric, in addition to normal bike mode.This bike is foldable for easy storage and transport. It comes with a tool set, making sure that he always feels prepared. It can go anywhere, anytime since it is rustproof. Has a very strong750 watt brushless motor that’s built to last. Lasts long on the charge, has a removable 48 volt battery that makes everything really easy. It has 7 speeds and can top out ot 30 miles per hour which is incredible for a bike. It has LED front and rear lights for safety and fat 20 inch tires for stability and durability. The 20 inch tires are the beat for doing tricks and rough terrain mountain biking. This bike has unparalleled durability for what it can do! This Auloor electric bike also has a really great smart climbing angle function that you can adjust for ease of going up any hill. While the electric mode tops out at 30 miles per hour, aditionally this bike has a pass mode that will increase your speed to up to 32 miles per hour for passing. This bike is made to last and I guarantee my son will be riding it for many, many years to come. This bike is of top quality and makes an amazing gift for any outdoor enthusiast! Although this bike is the perfect gift for my son, I could not resist giving it a try! I was able to ride with ease and I was quite surprised with the quality and durability. It was so easy to use, even for someone who hasn’t rode a bike in ages! The bike has everything you could possibly want, just an array of technologies for your every need and use. I’m very happy with this bike and the fact that it’s the only bike my son will ever need! It’s a lifelong companion.

It can handle a variety of road conditions, including uphill and downhill, slow and consistent speed, and acceleration.Differences Between Brushed and Brushless MotorsWhen it comes to the motor types typically found in electric bikes and conversion kits alike, they fall into one of two categories. Brushed DC motors use a configuration of wound wire coil to interact with electromagnets and the motor itself. The coil does not rotate, but the brushes come into contact with the electromagnetic regularly, which are the primary differences from a brushed DC motor.Brushed DC motors, otherwise known as a BLDC motors, use a permanent magnet to reach a similar result as a brushless motor. The coil rotates to meet this magnet, but there is no physical contact otherwise. This leads to a number of performance differences, which are slightly in line with when you compare direct drive vs a geared motor with electric bikes.A brushed DC motor uses a configuration of wound wire coils- the armature- acting as a two-pole electromagnet. When the motor is working, the coil and the commutator (a mechanical rotary switch) rotate, the permanent magnets and the brushes do not rotate, and the current direction change of the coil is completed by the commutator and the brush. When the current direction of the coil change, the electromagnet’s poles are changed and push against the permanent magnets along the outside of the motor. This contact of brushes and commutator wears the brushes that these brushes have to be replaced regularly. This replacement is not so expensive but to manage this work itself is not so easy.A brushless motor utilizes a permanent magnet as its external rotor or internal rotor. In addition, it uses three phases of driving coils and three hall sensors to track the rotor position. When the sensor tracks the rotor position, it sends out reference signals to the controller. Then the controller activates the coils in a structured way – one phase after the other. The brushless motor adopts electronic commutation, the coil does not move, and the magnetic pole rotates. As there is no physical contact from any parts of the motor inside, therefore there is virtually no wear and tear possibilities, making the motor’s durability limitless. These motors require sophisticated controllers, and it makes it possible for using three different windings, and power is supplied by individual windings according to the position they are in the movement. When the motor passes one winding, the controller passes the power to another winding, making the movement to continue without stopping.Brushless solutionIn brushless DC motors, an electronic servo system replaces the mechanical commutator contacts. An electronic sensor detects the angle of the rotor and controls semiconductor switches such as transistors which switch current through the windings, either reversing the direction of the current or, in some motors turning it off, at the correct angle so the electromagnets create torque in one direction. The elimination of the sliding contact allows brushless motors to have less friction and longer life; their working life is only limited by the lifetime of their bearings.Brushed DC motors develop a maximum torque when stationary, linearly decreasing as velocity increases. Some limitations of brushed motors can be overcome by brushless motors; they include higher efficiency and lower susceptibility to mechanical wear. These benefits come at the cost of potentially less rugged, more complex, and more expensive control electronics.A typical brushless motor has permanent magnets that rotate around a fixed armature, eliminating problems associated with connecting current to the moving armature. An electronic controller replaces the commutator assembly of the brushed DC motor, which continually switches the phase to the windings to keep the motor turning. The controller performs similar timed power distribution by using a solid-state circuit rather than the commutator system.Brushless motors offer several advantages over brushed DC motors, including high torque to weight ratio, increased efficiency producing more torque per watt, increased reliability, reduced noise, longer lifetime by eliminating brush and commutator erosion, elimination of ionizing sparks from the commutator, and an overall reduction of electromagnetic interference (EMI). With no windings on the rotor, they are not subjected to centrifugal forces, and because the windings are supported by the housing, they can be cooled by conduction, requiring no airflow inside the motor for cooling. This in turn means that the motor’s internals can be entirely enclosed and protected from dirt or other foreign matter.The construction of a brushless motor resembles a stepper motor, but the motors have important differences due to differences in implementation and operation. While stepper motors are frequently stopped with the rotor in a defined angular position, a brushless motor is usually intended to produce continuous rotation. Both motor types may have a rotor position sensor for internal feedback. Both a stepper motor and a well-designed brushless motor can hold finite torque at zero RPM.Brushless motors can be constructed in several different physical configurations. In the conventional inrunner configuration, the permanent magnets are part of the rotor. Three stator windings surround the rotor. In the external-rotor outrunner configuration, the radial relationship between the coils and magnets is reversed; the stator coils form the center (core) of the motor, while the permanent magnets spin within an overhanging rotor that surrounds the core. Outrunners typically have more poles, set up in triplets to maintain the three groups of windings, and have a higher torque at low RPMs. In the flat axial flux type, used where there are space or shape constraints, stator and rotor plates are mounted face to face. In all brushless motors, the coils are stationary.There are two common electrical winding configurations; the delta configuration connects three windings to each other in a triangle-like circuit, and power is applied at each of the connections. The wye (Y-shaped) configuration, sometimes called a star winding, connects all of the windings to a central point, and power is applied to the remaining end of each winding. A motor with windings in delta configuration gives low torque at low speed but can give higher top speed. Wye configuration gives high torque at low speed, but not as high top speed. The wye winding is normally more efficient. Delta-connected windings can allow high-frequency parasitic electrical currents to circulate entirely within the motor. A Wye-connected winding does not contain a closed loop in which parasitic currents can flow, preventing such losses. Aside from the higher impedance of the wye configuration, from a controller standpoint, the two winding configurations can be treated exactly the same.The maximum power that can be applied to a BLDC motor is exceptionally high, limited almost exclusively by heat, which can weaken the magnets. (Magnets demagnetize at high temperatures, the Curie point, and for neodymium-iron-boron magnets this temperature is lower than for other types.) A BLDC motor’s main disadvantage is higher cost, which arises from two issues. First, BLDC motors require complex electronic speed controllers to run. Brushed DC motors can be regulated by a comparatively simple controller, such as a rheostat (variable resistor). However, this reduces efficiency because power is wasted in the rheostat. Second, some practical uses have not been well developed in the commercial sector. For example, in the Radio Control (RC) hobby arena, brushless motors are often hand-wound while brushed motors are usually machine-wound. (Nevertheless, see “Applications”, below.)BLDC motors are often more efficient at converting electricity into mechanical power than brushed DC motors. This improvement is largely due to the absence of electrical and friction losses due to brushes. The enhanced efficiency is greatest in the no-load and low-load region of the motor’s performance curve. Under high mechanical loads, BLDC motors and high-quality brushed motors are comparable in efficiency.AC induction motors require induction of magnetic field in the rotor by the rotating field of the stator; this results in the magnetic and electric fields being out of phase. The phase difference requires greater current and current losses to achieve power. BLDC motors are microprocessor-controlled to keep the stator current in phase with the permanent magnets of the rotor, requiring less current for the same effect and therefore resulting in greater efficiency.In general, manufacturers use brush-type DC motors when low system cost is a priority but brushless motors to fulfill requirements such as maintenance-free operation, high speeds, and operation in explosive environments where sparking could be hazardous.Heating and ventilationThere is a trend in the heating, ventilation, and air conditioning (HVAC) and refrigeration industries to use brushless motors instead of various types of AC motors. The most significant reason to switch to a brushless motor is a reduction in power required to operate them versus a typical AC motor.In addition to the brushless motor’s higher efficiency, HVAC systems, especially those featuring variable-speed or load modulation, use brushless motors to give the built-in microprocessor continuous control over cooling and airflow.DurabilityBrushed DC hub motors are generally thought to be more durable and long-lasting than brushed hub motors. Why? There is not much physical contact between the components so they tend to stay in tip-top shape for a longer period of time. Brushless hub motors, on the other hand, feature brushes that constantly come into contact with the motor coil and other components. This leads to a degradation of these components, particularly the brushes themselves. In other words, you will have to get these brushes replaced regularly as a part of your overall maintenance routine.SpeedGenerally speaking, brushless motors allow for higher maximum speeds than brushed DC motors. This all boils down to energy efficiency. Brushless motors are highly efficient (85-90%) compared to brushed motors (75-80%). This increased efficiency also translates to battery life, which is important if you are comparing electric bike batteries of 36v and 12ah vs 48v 9ah.CostBrushless motors will tend to cost more than brushed motor designs, which will translate to the cost of the e-bike or conversion kit itself.Brushless DC Electric Motor Torque-Speed CharacteristicsA BLDC motor has permanent magnets which rotate and a fixed armature, eliminating the problems of connecting current to the moving armature. An electronic controller replaces the brush/commutator assembly of the brushed DC motor, which continually switches the phase to the windings to keep the motor turning. The controller performs similar timed power distribution by using a solid-state circuit rather than the brush/commutator system.The interface circuitry between a digital controller and motor. The waveforms show multiple transitions between high and low voltage levels, approximations to a trapezoid or sinusoid which reduce harmonic losses. The circuit compensates for the induction of the windings, regulates power and monitors temperature.BLDC motors offer several advantages over brushed DC motors, including more torque per weight, more torque per watt (increased efficiency), increased reliability, reduced noise, longer lifetime (no brush and commutator erosion), elimination of ionizing sparks from the commutator, and overall reduction of electromagnetic interference (EMI). With no windings on the rotor, they are not subjected to centrifugal forces, and because the windings are supported by the housing, they can be cooled by conduction, requiring no airflow inside the motor for cooling. This in turn means that the motor’s internals can be entirely enclosed and protected from dirt or other foreign matter.Shimano ShifterThis is the same Shimano seven speed shifter seen on our electric bikes. It is considered a “top bar” bike shifter. This is the only shifter that we found that will actually allow us to have our ebike throttle and a shifter on the same side of the handlebar. Lucky for us, it’s one of the best bike shifters on the market.This Shimano shifter is a seven speed, meaning it has 7 different shifting levels. On the surface, you have one large lever that you push with your thumb to shift up into low gear, and then there’s a button that you can push that’ll index through all seven gears to the highest gear. This Shimano shifter comes with an extra long cable and housing to fit on our longer frame bikes. It can be customized to fit on any length bike.Do most e-bikes have bike gears? Do they use Shimano shifters?The cheapest electric bikes will only have a single speed gearing system, meaning no shifter at all. In order to cut costs a lot of electric bikes below the $1,500 price point tend to only have 1 gear. In our eyes it’s fundamental for a bike to still have multiple gears. Gears help aid in hill climbing and also offers more range and support of pedaling.There are a lot of seven speed, eight speed, and nine speed shifters on the market in both the electric bike and regular bike markets. Seven speed is considered a standard.What role does a shifter play in an electric bike? How does having a shifter help an electric bike?If you have a hub motor electric bike, meaning the motor is located inside the wheel, the pedal ratios aren’t super critical, but they certainly will enhance your ride. The shifter mainly just allows you to catch up to the motor and have some sort of feedback during pedal assist. Many ebikes will be single speed which can be tough to catch up with your pedal assist level, leaving you pedaling for pretty much no reason other than to operate the assist. A Shimano shifter lets the rider get a bit of exercise, rotating the legs and get closer to feeling the output of the assisted power. On a hub motor system the ratio is fixed inside the hub and the wheel will spin whether you’re pedaling or not. What gear you’re in wont make too much of a difference difference because the ratio built into the hub is a single ratio.If you have a mid-drive motor, and you have speeds to shift through, then it works much like a transmission where you have the motor powering the chain ring or the sprocket. So, if you have seven speed with a mid-drive, that’s like a transmission in a car and you get multiple ratios versus the one ratio at a hub motor

   Auloor Electric Bike What a DIFFERENCE

   My first review was a 3 star but after communicating with the seller and getting the upgrade the bike does exactly what it’s advertised 30MPH. Please keep in mine that your weight can make a difference. I am a Big guy and I got the bike to do 30 MPH in the 5 setting.It’s a bit heavy and needs a little brake adjustment, I rode 12 HARD miles and my battery sits at 70% and I never took it out of full electric. I recommend that you buy an extra battery to carry with you just in case if you have limited mobility as I have.
