3 Thing You Should Consider Before Buying An Electric Bicycle (Part 2)

Greetings from GoGoA1 team!

We had talked about the main 3 things you should consider before buying an electric bicycle on part 1. Are curious enough to read the second part? Here we go!

2. Battery
First generation of e bikes used Sealed Lead Acid (SLA) battery with mid to high power on it. As technologies develop, this kind of battery is replaced by Lithium Ion/Polymer. The Lead Acid battery had also been used in submarine, solar energy storage, and automotive and traction industry before. It has advantages for its robust, tolerant of overcharging, and deliver high current. It also less costly. However it only has short life span, it’s slow and inefficient charging.

While The Lithium Ion battery has more advantages compare to former battery.

  • It is fast charging with efficiency near 100% even when discharge
  • The weight is lighter, more than half lesser of Lead Acid
  • Long life cycle around 5000 times compared to 400-500 cycles in Lead Acid
  • Environment friendly

Despite its cost is pricey, but it gives more benefits for any application.


Lithium Ion Battery

Due to the facts that Lithium Ion Battery has taken over the place for decades and its superior specifications, GoGoA1.com had already set the plan to provide electric conversion kit with Lithium Battery on it. Also all electric bicycle under GoGoA1.com company are installed with the same battery. Furthermore, we still can find the application of Lead Acid battery on electric bicycle in the market. The mid drive cycle can be installed with either Lithium Ion or Lead Acid depends on customer choice.


3. Controller

Basically the controller can be pedal based and throttle based. The former means that the electric power will be activated when pedaling. Once the button is turned on, you can feel the electric force by only pedaling just like the way people cycling. It comes naturally. While the other hand, throttle based controller is way different. The source is in a throttle. Once the button is turned on, you can only pull the throttle to get the electric force. No need pedaling. It is suitable to ride on road as there is no particular effort to push the pedal.

The above throttle-based controllers are used depending on the kind of motor. BLDC controller is used for 3-phase BLDC Hub Motor while PMDC controller is used for single phase PMDC Motor.

So now you know what things to consider before purchasing your first Electric Bicycle.

3 Things You Should Consider Before Buying An Electric Bicycle (Part 1)


Greetings from GoGoA1.com team 😉

In a previous post, we had talked about the advantages and disadvantages of Electric Bicycle. We all agree that Electric Bicycle has more positive things and be worthy enough to purchase. Today we are going to explain more what specifications are there to help you consider before spending your money. Let’s check it out!

Nowadays Electric Bicycle has reached the heart of people specifically Indians as we already know its advantages compare to non-electric ones [read the post here], but do we all know what it is exactly? How does it run on electrical driven?

Electric Bicycle (e-bikes) is bicycle with an integrated electric motor to reduce human power while riding the cycle . It will help reducing 30% human effort up to 100% (effortless) depends on choice. There few types of Electric Bicycle in the market. Most of them are ready-to-use or installed cycle, which we can directly ride on it as we purchased and non-electric cycle, which we can convert with electric conversion kit. E bike has 3 main parts that attached on it in order to give electric-driven cycle.

1. Motor

In an e bikes, the motor plays an important roles to give a different result. However this can be customized with the specification of each motor, the outcome still be not the same and satisfying. The motors can be hub motor and mid drive motor. Our bicycles use Brushless DC (BLDC) motor in rear wheels [see the full post of BLDC motor here]. In other hand, mid drive motor can be BLDC or PMDC (Permanent Magnet DC).

Hub motor is often preferred as a driven in an e bike due to its easiness to only pull throttle when we are going to ride in electric mode. This kind of motor are widely used in the market right now. It can be installed in the front or rear wheels, while most of e bikes put in on the latter. GoGoA1 Solomo black mag

The advantages of rear hub motor are users will get pushing effect instead of pulling. It is considered safer when a rider tries to make sudden stop. While the front hub will pull a rider out from the cycle. Besides hub motor is affordable enough compare to mid drive. It gives a best output for an e bike beginner out of there.

2. Battery

First generation of e bikes used Sealed Lead Acid (SLA) battery with mid to high power on it. As technologies development, this kind of battery is replaced by Lithium Ion/Polymer. The latter is bringing new technologies

Next part, we are going to explain more the second and third important things on an Electric Bicycle. Just follow this blog and stay tuned 😉

GoGoA1.com clients common questions about products

Long time no see, dears!

So today GoGoA1.com team prepared answers on the questions that people usually ask about our products. This post will give you more information about our products in general and if it won’t be enough you can contact us anytime and do not afraid to ask the questions. We are here to help you;)

1.Can I travel with my electric vehicle? What about transportation of Li-ION Battery?

Some mass transportation providers have specific regulations regarding travel with electric vehicles. Some providers treat them as baggage or an assistive device, others do not.

In general, the lithium-ion batteries are considered hazardous material and are not allowed on commercial passenger airlines. Still, you can ship your EV anywhere by ground.

Check with your local transit provider for more information before your journey.

2.Can I use my EV in the rain?

You can use our electric-bikes in rains because its motor has IP54 protection. The IP stands for ingress protection and means its ability to stand in extreme weather condition. IP54 represents that the equipment will operate in dusty conditions, and will resist splashing water.

GoGoSegways and GoGohoverboards are not designed for exploitation in water so you cannot use it in rains.

3.Do GoGoSegway, GoGohoverboards and e-bicycles have weight limits?

For a rider safety and for reducing the risk of vehicles damage, our products have weight limitations. Minimum weight of GoGoSegway and GoGoHoverboard rider should not be less than 20kg, and the maximum weight should not be more than 210 kg.

4.How to balance GoGoSegway and GoGohoverboard?

The smart system of that self-balancing electric vehicle understands the human body and the way how it copes with the system, so that is the way how self-balancing scooters work.  It balances the rider by applying forces to the ground in the direction of the lean.

So to accelerate that vehicle you need lean forward and to stop – take a straight position.

If you ride GoGoSegway -for turning on the left it on the right – just turn handlebar to the right direction.

If you ride GoGoHoverboars – for turning on the left it on the right – press down slightly with the front of your right foot if you want to turn left and do the same with your left foot if you want to turn right.

5.How can I become an Authorized GoGoA1.com dealer or distributor?

We provide people with an opportunity to do business in electric vehicle industry as OEM&ODM and supplier&component supplier, stockiest and virtual franchising. For more details, please, contact us through sales@gogoa1.com.

6.BLDC and PMDC difference

BLDC Motors combines best features of alternating current and direct current motors. It determines advantages of BLDC motors:
a.There are no brushes and physical commutator in BLDC Motor, so its’ construction becomes more compact and lighter.
b.Commutations losses and energy consumption reduce because instead of a commutator and brushes BLDC motor uses an electronic controller to create a rotate that will transform electrical energy into mechanical.
c.BLDCM construction allows you to exploit those motors in water, aggressive and explosive environment.
d.Have high-energy datum. Its’ efficiency is more than 80-90%.
e.Have a wide range of change rotational frequency.
f.Have long service life and high reliability due to the absence of sliding electrical contacts.
2.Permanent magnet DC motor works on the same principle as normal DC motors, i.e. when communicator goes into magnet field it produces force.
a.No input power to consume for if field excitation which improves DC motors’ efficiency.
b.Smaller in size because of lack of field coil.
c.Cost advantage. Using of PMDC reduces manufacturing cost, also PMDC are cheap in cost.
d.Low-voltage PMDC motors produce less air noise.
e.When you need high starting and acceleration torque, predictable motor speed properties, compact size, and energy efficiency, permanent magnet DC motors may be the solution.

7.How to fit an electric conversion kit?

Motor – it depends on the type of wheel. It is easy to fit Magnesium wheel hub– all you need is to replace your back wheel with the magnesium hub motor wheel.

For fitting spoke wheels bicycle with a hub motor, you have to remove spokes from the wheel, place the motor and then put the spokes back.

Controller and Battery box placing fully depends on your personal preferences.

PMDC Motor Basics

Wednesday greetings from GoGoA1.com team!

Our technical department is cool as always so  we are here again with our new short post about PMDC Motor.

Don’t procrastinate – read it 😉

We already wrote about Flemming’s left hand rule, but perhaps, there are new readers who didn’t read our previous post, so we’ll shortly explain it again.

Flemming’s left hand rule– this rule is applicable for d.c motors. The rule states that, whenever a current carrying conductor is placed in a magnetic field, a force acts on the conduct in the direction perpendicular to both, the current and the magnetic field.

Here you can see Fleming's Left Hand Rule demonstration
Fleming’s Left Hand Rule demonstration

Since all D.C motors work on Flemming’s left hand rule, it’s essential to establish a magnetic field.

This magnetic field is produced by the means of magnets.

When permanent magnets are used to create the magnetic field, the motor is called a Permanent Magnet motor or a  PMDC motor.

Construction of PMDC Motor:

STATOR – is a steel cylinder with permanent magnets placed at the inner periphery of the steel cylinder.

PMDC motor construction

The magnets are placed so that the alternate poles of the magnets are facing the armature or the rotor (i.e if the north pole of one magnet is facing the rotor, the south pole of the next magnet will be facing the rotor).

ROTOR- is made of varnish insulated, slotted circular laminated steel sheet. The rotor consists of core, winding and commutator.

Carbon or graphite brushes are places with spring pressure on the commutator segments to supply current to the rotor.

Working principle of the PMDC Motor:

As mentioned earlier, the D.C motor works on Flemming’s left-hand rule, when the current carry conductor comes inside a magnetic field, it experiences a mechanical force which is governed by the left-hand rule.

The armature/ rotor is placed in the magnetic field of the permanent magnet(i.e the stator); the armature rotates in the direction of the generated force.

The conductors on the armature experiences the mechanical force of F = B.I.L Newton, where

B =  magnetic field in tesla;

I = current in Amperes;

L = length of the conductor in meters;

Each conductor experiences forces and the compilation of these forces result in torque, because of which the armature rotates.

Advantages of PMDC Motor:

  1. No need for field excitation arrangement
  2. No input power is used for the excitation of the field, thus increasing the efficiency of the motor.
  3. No field coil, thus the size of the motor is small.
  4. Cheap and economical for fractional kw application.

Disadvantages of PMDC Motor:

  1. There is a chance of getting the poles permanently demagnetized (partial) due to excessive during starting, overloading and reverse the condition of the motor.
  2. The magnetic field is present all time, even when the motor is not being used.
  3. A pmdc motor has a lower induced torque per ampere turns of armature current than a shunt motor of the same rating.

Applications of PMDC Motor:

  1. In automobiles for windshield wipers and washers, air conditions, for heaters, to raise the lower windows, etc.
  2. In electric bikes
  3. In toy industries
  4. Used in electric tools like drilling machines, hedge trimmers, etc.

BLDC Motor Basics.Part 2

Greetings from GoGoA1.com team!

In the 1st part of our BLDC Motor Basics post we promised you to provide information about the BLDC motor principle of work,  about improving the performance of it and the BLDC motor types. We appreciate our readers and we keep our promises, so here it is – read, learn and enjoy 😉

Working principle: basic interaction between a permanent magnet(rotor) and an electromagnet(stator).

For simplicity,

Consider three stator coil winding arrangements A, B and C.
When coil A is given a dc supply, it gets energized and becomes an electromagnet.

The opposite pole of the rotor gets attracted to the stator(opposite poles attract). As a result, the rotor pole moves near the energized stator.

As the rotor nears the coil A, coil B of the stator is energized. Similarly, as the rotor nears coil B, coil C is energized. After that, coil A is energized with opposite polarity.

This process is repeated, and the rotor continues to rotate.

Improving the performance of the BLDC motor:

Problem –  as seen above, only one coil is energized at an instant. The 2 inactive coils greatly reduce the power output of the motor.

In order to avoid that, energize coil B with the same polarity as coil A, when the rotor is in the position with coil A.

In this way, the combined effect will push the rotor and produce more torque and power output from the motor. The combined force also makes sure that a BLDC has a beautiful, constant torque nature.

To energize the 2 coils at the same time, the free ends of the coils are connected together.

Electronic controller unit:

An ECU is used in a BLDC motor to determine the position of the rotor and to energize the coils accordingly.

The Hall-effect sensor is used to sense the position of the rotor.

This sensor gives information to the controller, which energizes the stator coils accordingly.

Types of BLDC Motor:


In the Out-Runner type, the magnets are placed on the outside of the stator, as shown in the fig. below.

Compared to the in-runner type bldc motor, the out-runner has more mechanical advantages.It has comparatively more torque.

Comparatively, It can swing heavier props.

 2. In-Runner:

In the In-Runner type of motor, the magnets are placed on the inside of the stator, as shown in the fig. below.

Comparatively, it runs on high RMP.

Inrunner and Outrunner BLDC types of motor
BLDC Motor types


Advantages of a BLDC motor:

  • Better speed v/s torque characteristics
  • High dynamic response
  • High efficiency
  • Long operating life due to lack of electrical and frictional losses
  • Noiseless operation
  • Higher speed ranges

Applications of BLDC Motor:

  • Transportation
  • Heating and ventilation
  • Industrial engineering
  • Model engineering
