If you are looking into building your first DIY e-bike, you will probably find that a lot of builders are using the Bafang mid-drive motor conversion kit. You might wonder: “why are so many people using this kit?” and “is it really that good?”. "how to choose thr right motor". In this review, I will give the answers to all these questions.

1.From Production Time

The BAFANG BBS02 was first released in 2014 with the "A" version of the controller MOSFET, which could not support higher currents and was prone to overheating, which caused many motors to fail prematurely. To better address this issue, "B" version was released in 2016. This (supposedly) has a better controller and a higher quality "brand" IRFB3077 FET, which converts more input watts into power and less input watts into waste heat.

The Bafang BBSHD was launched in 2016, and the main difference between the two motors is that the HD is larger and has external heatsinks (to help dissipate heat). The stator is 66% larger and the controller has 12 IRFB3077 FETs that can handle 30A of continuous current. The input voltage is the same as the BBS02.

2.From Installation

The BBS02 only comes in a single bottom bracket size.  It can fit in bottom brackets that are 68mm and 73mm wide.  It fits a standard threaded 68 or 73mm bottom bracket.  If you have a press-fit bottom bracket of this width, we have adapters that can convert your bottom bracket to the threaded standard so the BBS02 can fit.  If you have a wider bottom bracket, you will need to use either the Bafang BBSHD or CYC X1 Pro.

In addition to the 68/73mm bottom bracket sizes that the BBS02 fits, the BBSHD also comes in a 100mm and 120mm BB width.  These are typically used exclusively on fat bikes.  The BBSHD is always an excellent choice for a fat bike because they are heavier and often used in sand, snow, or steep terrain.  However,  The 100mm also bridges the gap down to 83-92mm bottom brackets. These are popular BB widths for high-end mountain bikes.  To fit the BBSHD, these typically require press-fit adapters and 8-16mm of bottom bracket spacers, and these conversions are solid.  When possible, the spacers should go on the non-drive side to help equalize the Q-factor.  Exceptions are when some spacing is necessary on the drive side so that the “gear reduction housing” clears the right chain stay.

Carbon frames often cannot accommodate a Bafang mid-drive motor because the bottom bracket shell casing is too thick. Bafang mid-drive motors have a 12mm clearance between the motor housing and the spindle. Most carbon frames have a BB shell casing thicker than this, and the motor won’t slide into the bottom bracket. The newer design of the CYC motors eliminates this problem.

3.From Power

As shown in the record table in the picture， the BBSHD produces more power than the BBS02 at the same battery voltage, although there is only a 294 watt difference (if using a 52v battery), the big difference in the feel of the HD is the amount of torque it produces. This is up to 160N.m against 120N.m for the 750w.The bigger motor spins faster – 130-150 rpm (120 rpm for the 750w) and has a reduction ratio of 1:21.9.

So the BBSHD is much larger than the bbs02, and the BBSHD is 3 pounds heavier than the bbs02, the BBSHD uses more powerful components and a more powerful controller.

4.From Price

If you want an off-road electric bike that you can hammer the hell out of, then I would definitely say go for the BBSHD. The extra 272USD on the price may seem a little excessive, but it will give you over any steep incline, Cross any terrain and conquer all impossible paths

If you are going to be doing some mild cross country-type riding and are not going to be using the throttle or tackling any ridiculously steep climbs then the BBS02 may be more suited to your needs.

If you live an active lifestyle and are passionate about mountain biking, you need to understand all the preparations for a successful ride, and most importantly, how to avoid injury. Bicycle-related injuries can change from minor scratches to traumatic injuries that require time to rest to recover. Abuse of muscles, ligaments and joints can also cause non-traumatic injuries. Please follow the tips below to increase protection and avoid potential injury while riding a bicycle.

1.Suitable Keeping your body healthy will help prevent wear and tear. Especially back injury. The cyclist bends over, their core is always in tension. You may need side elevations and sit-ups to strengthen the usual cyclist’s position and focus on training the core.

2.Become flexible Your fitness routine should be flexibility exercises to help you a trail and reduce the chance of injury. Yoga is a perfect stretching exercise to complement your cycling exercise. Yoga exercises can also help you increase strength and flexibility.

3.Do some warm-up before riding It is best to warm up for five to ten minutes before riding the bike. The regular Bobby is a good full body warm-up, especially during stretching exercises. If you don't feel warm up, you can ride steadily on a flat surface for at least 15 to 20 minutes.

4.Know your journey

Before riding a bicycle, you should at least have a plan to start and end your journey. If you have a program that considers time, location and ride intensity, it will be the best choice. Set how long you want to complete. If you ride for a long time, fatigue may cause serious injury.

5.Adjust mountain bike

You need to conduct a thorough inspection of your bike and look for any problems that can be resolved. You also need to fine-tune all the working parts of the bike and replace any damaged parts. Make sure that all bolts and screws are in good condition and that all components of the bicycle are working.

6.Wear a helmet

Wearing helmets on trails or roads should be a common practice. It is the most basic protective equipment that every cyclist should follow.

7.Wear bicycle glasses

Wearing bicycle glasses when riding is one of your main protection measures. It can prevent your eyes from getting dirt. Once you can't see, dirt will make you lose your balance. Depending on your bike route and weather conditions, there are transparent glasses and sunglasses.

8.Put on body armor

In addition to wearing a helmet and riding glasses, you should also wear knee pads and wrist guards. Wearing protective equipment can reduce the chance of injury, such as bruises and scratches.

9.Always bring water

It’s best to remember that the top priority is to keep your bike hydrated while riding. You should carry at least three percent more water than you plan to carry. You can refresh yourself by hydrating yourself during the journey.

10.Maintain blood sugar levels

Glucose is a good source of energy and you can find them in energy bars, energy drinks or energy gels. You can have some snacks while riding a bicycle.

Riding a mountain bike has the risk of injury, but it can prevent many accidents. Avoiding these mountain bike injuries should be your first consideration, but if you are injured due to the negligence or deliberate actions of others, make sure you have a personal injury lawyer that you can turn to. Your knowledge of how to ride a mountain bike will give you a fun and exciting experience.

What is the difference between Electric assist bicycle and Electric bicycle?

First,we should know that the word for electric assisted bicycle is "Pedelec", which is a combination of pedal (pedal) and electric (electric). It specifically refers to a bicycle equipped with an electric motor that needs to be driven by a pedal. "Electric bicycle = bicycle + power assist system (PAS)", and PAS is the abbreviation of Power Assist System. Therefore, electric assisted bicycles are based on the addition of power assist system (PAS) to the bicycle, the purpose is to make cycling easier.

Electric bicycle refers to a mechatronics personal vehicle that uses storage batteries as auxiliary energy sources on the basis of ordinary bicycles and is equipped with motor, controller, storage batteries, handlebars and other operating components and display instrument systems.

In short, the relationship between electric-assisted bicycles and electric bicycles is more like the relationship between plug-in hybrids and light hybrids in hybrid vehicles. Even if the electric-assisted bicycles are driven without electricity, the impact will not be too great. With the assistance of electricity , Mountain bikes can climb difficult peaks, road bikes can give you the opportunity to compete with your cousin. Of course, how long you can run with your cousin. It is basic on your battery. Electric bicycles are not assisted by electricity. The impact will be relatively large, and it will be much slower to rely solely on human power. What are the specific differences between them, let us continue to look down.

1.Different battery capacity

The battery capacity of electric-assisted bicycles is generally smaller than that of electric bicycles. Because the core of electric-assisted bicycles is always human-driven, and the electric system is only auxiliary. While electric bicycles are driven by electric, and electric-assisted bicycles need to consider the issue of weight.

For example, the weight of an electric-assisted road vehicle is about 12kg, which is already very light compared to electric vehicles. But it is placed in road vehicles. It is already like a tank. If it loses power assistance, the electric-assisted road vehicle is inferior to the traditional large group road vehicle, it already was not good at climbing, starting, and rocking.

2.Different functions of the pedal

The pedal of an electric road bike is more like a 48V motor in a light hybrid car, than improving the riding experience and feeling. While the pedal of an electric bicycle is like a plug in a light hybrid car. I can still speed on the street without a pedal.

3.Different areas of application

Electric bicycles are mainly used in daily life, such as worker in crowded urban areas and deliver food by takeaway brothers . Now some cities have shared electric bicycles to solve the problem of 1KM at the end of work. Therefore, there will be additional dishes on the electric bicycle. Such as baskets, rear seats, rear-view mirrors and other equipment and choose larger and softer cushions.

Most of the electric-assisted bicycles encounter unmovable routes when traversing mountains and ridges. Electric-assisted bicycles are used as an aid to climb the mountain peaks. When you are site last ten kilometers of a small long distance is really not moving, electric-assisted bicycles can reach the end point.

Electric bicycles are mostly used in life and convenience. While electric bicycles are generally used to solve some roads problem. Such as can't be walked, the slopes that cannot be climbed, and so on.

4.Price

Due to various reasons such as body materials, parts production costs and research and development, the price of electric bicycles is generally around $2000USD. Electric bicycles are only $500USD, because the production cost and materials are much cheaper than electric bicycles.

In short, an electric-assisted bicycles is more like a family car that meets daily needs. It has everything and is cheap. An electric bicycle is more like a super car, which can meet performance requirements while improving the driving experience.

May-August is the most suitable season for short-distance travel. In order to make short-distance riding easier and smoother, I have a few things I want to recommend to you.

After more than 20 years of development, the electric bicycle industry is already a very mature industry, but many consumers still have an asymmetrical understanding of electric bicycles and are often fooled by dealers. It needs to be several times more than replacing other batteries. In fact, the internal cells and battery structure have the same functions, just stick a brand label.

In fact, electric bicycles have four major components: frame, motor, battery, and charger. A good electric vehicle is these four good things. Among them, the frame can be the frame of your own bicycle. The other three items need to be purchased on the website. Some brand car companies can produce their own motors, so how to choose a motor For batteries, the most important thing is to choose a store with high cost performance and after-sales guarantee. Next, I will recommend some electric bicycle motors.
