5 Best DIY Electric Bike Kits of 2019

Posted on

Electric bikes are excellent pieces of engineering. Whoever thought that adding a small motor that helps you pedal with less effort and give you a boost must be genius. Having one, especially if you love riding your bike, is extremely helpful. It can help you with your commute since you’re not going to be as tired when you reach your destination. No matter what you ride, there is an electric bike equivalent that will significantly improve your overall riding experience.

The question now is, apart from your current bike, do you need to buy a brand-new electric version? High-quality ones can sometimes cost an arm and a leg, and owning two bikes might be a little tricky to maintain. The great news is that you absolutely don’t have to.

Electric Bike Conversion Kits

You can convert your existing bike to an electric version using a conversion kit. This is really helpful when you have invested a considerable amount on your ride. Whether it’s a mountain bike, road, bike, or even a hybrid one, you can absolutely electrify them at a fraction of the cost of getting a brand-new e-bike.

Converting your existing ride is pretty easy, all you need to do is to replace one wheel either the front or back with a powered one. Another way to do this is to attach a drive unit that boosts your power output as you pedal so you can start climbing those hills with ease.

It’s that simple, and it’s great to know that there are conversion kits that can help you with all of this. As long as you’re pretty handy in using tools and know your way around your bike, you can install any of these kits with no trouble at all.

BAFANG BBS02B MID DRIVE ELECTRIC BIKE MOTOR CONVERSION KIT

So far, we’ve reviewed a few kits that use hub motors. This is great, however, the performance ceiling for those power units is a bit low. To be able to squeeze more function, you will need to change the type of motor entirely. This is where the Bafang BBS02B enters the conversation.

Things to Consider in Choosing an Electric Bike Kit

The latest technologies in electric motors and drivetrains have made it possible for efficient and affordable conversion kits. You can now quickly adapt your standard bicycle to an electric version making it possible for you to enjoy the best of both worlds.

A great thing with a converted bike is that you still get all the benefits of a traditional one but with a flick of a switch you can also get around faster and farther at a fraction of the effort. Some people will prefer e-bikes because you can commute to work or school without getting all sweaty along the way.

One thing is for sure when you embark on a conversion project, you’re definitely going to save a lot of money compared to when you buy a brand new one. You also retain the advantages of both, while completely eliminating the disadvantages of a traditional bike.

In choosing the electric bicycle kit to get, you want to take into account how handy you are with tools. If you own a bike, it is likely that you’re quite skilled in using them so you will be able to do the conversion by yourself. The great thing with getting a kit is that it comes with everything you need. The major parts like the motors are assembled, and all you really need is to fit them on your bike and screw them in place.

Types of Electric Bike Conversion Kit

There are a few ways to convert your existing bike into an electric riding machine. Different types of motor and drivetrain combinations can produce amazing results. This is a great thing about e-bikes since there is a set out there that’s perfect for what you currently have.

Electric Bicycle Wheels

This is probably the most common conversion kit in the market. It is also one of the easiest to install as it mainly involves merely swapping out the wheels. Of course, you’ll need to connect it to other minor components like batteries, if required, but it’s still very straightforward to slap it on to your bike.

The way it works is that the wheel comes with a particular hub and gear that gives you a boost as you pedal. Batteries can be installed within the wheel itself or mounted somewhere nearby.

There are two different types of electric bike wheels, the front, and rear. The front wheel motor is excellent for road riding since the weight is distributed evenly throughout the bike. If you’re using a front-powered wheel, the batteries are installed on the frame just so your steering does not get too heavy. A rear wheel motor, on the other hand, is suited for off-road use as it provides added traction due to the added weight.

Front and rear hub motors are generally more affordable options since there are fewer moving parts and interactions with the traditional components of a bike. If you’re looking for an affordable conversion kit, then hub wheel units are the way to go.

Mid Drive Motors

Central and mid-drive motors are what complete e-bikes usually come with. It’s a popular design since the entire installation is mounted to the frame of your bike. This low placement has its advantages as it lowers the center of weight, making your ride more stable and smoother. Having this configuration installed will make you feel that you’re just riding a regular bike, and that’s a good thing.

The way this type of motor works is a bit more complicated since it takes your motion through the pedals and substantially boosts it. Then it directs the total power into the drive system, so you travel faster and farther with less effort.

Important Components You Will Need

Apart from the motors, there are some crucial components that you need to complete your setup. Just the power units alone won’t completely convert your bike to a full electric device. Here are some additional parts that you need so your bike knows when to activate the motors and where to draw power from.

Sensors

One vital part that you need on an electric bicycle is the sensor. Without this, your motors won’t know when to kick in. Remember that e-bikes are designed differently compared to hoverboards and skateboards as they use motors that basically are just on and off. Activate the motors, and you’ll move. Electric bikes, on the other hand, need to know when they can turn the motors on since they’re more for assisting rather than your primary power source.

There are two types of sensors, namely speed and torque. The speed sensor looks at your pace, so that means as soon as you start pedaling, it activates the motor to begin assisting you. As soon as it detects motion, it kicks in and turns on your motors, and you’ll be able to feel it.

The other sensor is the torque sensor, and let’s say it’s a lot smarter than the previous one. It detects your pedal movements, and it matches your speed. This comes in handy if you’re slowly moving to weave through traffic. Now, when you hit the open road and start to increase your pedal power, it senses that, and it will tell the motor to crank it up. This type of motor provides better cornering performance.

Batteries

Batteries are another critical component that you need for your electric bicycles. They provide power to your motors so that they can push you forward. On average, a good battery can give you about 40 miles of range with pedal assist, or just 20 if you rely on them a lot. Older electric bike models use lead-acid types, basically a smaller car battery. However, the latest models now use lithium-ion cells since they’re significantly lighter and more efficient.

Getting the Kit For Your Bicycle

It all boils down to the type of conversion kit you choose. Most of these can be installed on your bike without any problem, so whether you want a hub wheel motor or a mid-drive one, any of these should work.

Just remember that hub motors are the more affordable option. If you mostly use your bike on city roads that are generally flat and don’t need the extra power from a mid-drive unit, then hub motors are your choice. However, if you want to take your bike on off-road mountain trails, then it is recommended that you get a mid-drive motor.

Now, you don’t have to spend a fortune on a decent electric bike. You can rely on any of these conversion kits to change things up and turn your bike into an energy-efficient machine that will take you just about anywhere without exerting too much effort.
