Best & fastest electric bike conversion kits

The increasing use of electric bikes or e-bikes makes it the talk of the town. For one, they are friendlier and less harmful to the environment. Another reason is it is easier to paddle than the standard two-wheel bicycle. I still get enough exercise as if I were riding a traditional bike. Health-wise, there is not a real drawback to you.


When we tested the various products, we found that the most powerful electric bike conversion kit without batteries was the AW 48V 1000W. Here are the results from our testing:

The improvement and progression in recent technologies make people more inclined to different transit methods. On the other hand, the market welcomes more availability and affordability of electronic bicycles.

However, to set your expectations, no e-bike is as cheap or affordable as a traditional bike. Reducing my carbon footprint is one of my personal goals, so I think getting one is a great way to start.

Why you can trust us & how we picked

I live in a small space, and I like practicing minimalism. I already have a bicycle that I love. So what did I do? I searched for ways to possibly have an electronic bike without replacing my current one. It is where I discovered conversion kits. It’s the reason I think you can trust my stance on electric bike conversion kits.

Repurposing your unit and choosing the right one is a win situation for you, assuming it is still in top condition. Conversion kits allow more juice when riding uphill or powering through heavy cargo loads. Most kits include controls, sensors, a battery, and a motorized driver unit. I picked products with different capabilities to ensure there was something for everyone.

This article guides you through everything you need to know and recommends the best kits available in the market. 

Best, fastest electric bike conversion kits

I have seen different styles and types since I started my interest in conversion kits. I know they offer value and versatility to travel. One of the several advantages of opting for a kit is keeping the existing bike you love.

The list below shows the best, fastest electric bike conversion kits we tested. I can confidently say these are the most reliable and powerful ones. You can compare whether you should opt for conversion kits vs e-bikes but these can take you further into your rides.

Remember, the units need a charger to power up the battery.

EBIKELING Waterproof Wheel Hub Motor E-Bike Kit Conversion System

I think the EBIKELING waterproof hub system is the best among these five products. Its design works on every terrain or trail you wish to take while being robust and efficient. The battery life is incredible, so you will not worry about losing power while out. I did buy it after a fair bit of looking at customer reviews.

The pedal assist sensor (PAS) works excellently without a throttle response. It helps me avoid getting an uncomfortable wrist position if I pass through crowded streets or traffic. The unique LCD also tells me the battery level, speed, error codes, wattage, and distance traveled.

The hub attaches to the aluminum double-wall rim, assisting. I can recommend the EBIKELING hub to anyone who wishes to convert their traditional unit.


  • The LCD is an excellent addition to the package, making it perfect for long and demanding trips
  • It aids me in overcoming steep hills and challenging terrain

Best Electric Bike Conversions Kits With Batteries

Bafang 1000W BBSHD BBS03 Mid Drive Motor Kit with 48V Lithium Battery

I find the Bafang 1000W BBSHD BBS03 universally compatible with several bicycle types, including the mountain bike. It fits a JIS standard 68-73mm, 100mm, and 120mm bottom brackets.

The products come from their warehouse in Los Angeles, ensuring as fast as two-day shipping for most US customers. One thing worth noting before purchasing the 48V battery is that the color display may show it is not yet full despite being full. I recommend you pick the 52V if this bothers you. Both will work as expected, so there are no performance compromises.

I received the following parts when I ordered one for myself.

  • Mid-drive BBSHD 1000W motor
  • Brake levers
  • Chaining wheel
  • Thumb throttle
  • Magnets
  • Speed sensors

The Yose 500W kit has a 500W rear motor with a 48V 13Ah battery. The maximum speed of 40 km/hour and max torque of 67 Nm make it a powerful contender.

The BMS system prevents over-discharging, overcharging, short circuits, and overcurrent. A simulation proves it can retain 78% capacity even after 1000 cycles.

The bottom bracket fits a standard 68mm to 73mm. It makes it suitable for different applications, such as commuter, mountain, and road bicycles. Bafang also provides expedited shipping via FedEx, which takes two to seven days to any US address.

20-Inch Electric Bike Conversion Kit With Battery

Kunray Front Wheel Motor 350W 36V Kit

The Kunray 350W packs a 20-inch brushless gear hub capable of achieving speeds between 15 to 18 mph. It has a maximum load of 330 lbs / 150 kgs. The upgraded eight-pedal assistance system (8-PAS) has more sensitivity, allowing you to ride without throttle limits. 

Electric Bike Conversion Kit 700c

My favorite for this category is the EBIKELING 700C Front or Read Wheel Hub. Aside from easy conversion from traditional to electronic bicycle, it rocks an aluminum double-walled rim with a built-in motor.

The powerful 700C motor takes you further in your ride. You have to choose between a back or front mount during the ordering process. The motors are available in four variants – 500W, 750W, 1200W, and 1500W.  

Make sure you have a tire that fits.

How fast do electric bikes go?

electric bike kit

They usually go as fast as 20 mph for class 1 and class 2, while class 3 can go up to 28 mph. We recommend checking the manufacturer’s information sheet for the top speed. It differs with each manufacturer and model, so watch out for these.

Converting your bicycles from traditional to electronic is completely legal. It does not violate any state’s law or rules as of this writing. However, some states may have age restrictions, so check with local laws for it. 

Factors to consider

There are various factors to consider when you’re buying an electric bike conversion kit which we have listed below.

Battery capacity

The most important factor to look out for is a minimum 10Ah rating. The battery is dependent on the user. A front hub is the most common, followed by the rear hub. The mid-hub is more complex and is only compatible with a few units. 


You will want to make sure the kit you’re getting works with the frame, wheel size, and brakes that you currently have. You don’t want to get into the installation process to figure out they’re not compatible.

Motor power

How much assistance you’re getting as you’re riding is determined by the power of the engine. You might want more power in certain terrains and less in others. There could be legal limitations depending on where you live.


Some kits are heavier than others. While the electric support should make up for this weight, it’s still worth considering.


Some kits are more expensive than others. Prioritize the features that are important to you so you can still stay within budget.

Customer support

You’re spending a couple hundred on this product, so you’ll want to make sure the customer support is there to help if you need help converting your bike.

Ease of installation

Not all bike conversion kits are equally easy to install. Read the reviews to find out how easy it is for the one you’re considering.

Additional features

Some of the higher-end conversion kits come with things like regenerative braking. Figure out if that’s something you want.

How much do electric bike conversion kits cost?

As we tested different electric bike conversion kits, we found that they typically cost between $150 and $800. While you can pay more for them, that’s the range most consumers will land in.

Got any more questions about conversion kits? Read on below.


The following are the frequently asked questions regarding electronic bicycles.

Are e-bike conversion kits worth it?

Yes, they are worth it. 

How hard is it to convert a bike to electric?

It took me one hour to finish. It depends on how fast you can complete the conversion process. Some may take two or three hours. 

How fast can a 750-watt bike go?

It goes as fast as 28 mph.

Do all electric bike conversion kits come with a battery?

No, not always. You may need to purchase a battery separately. I recommend double-checking the information on the product page before you purchase.
