Best Electric Bike Conversion Kit

Electric bike conversion kits are proving a popular money saving choice as an alternative to buying upfront expensive e-bikes. These bike conversion kits allow you turn your normal bike into an electric bike via adding certain components such as a motor which are included in the conversion kits. This is a pretty cool option if you are looking to have your own custom designed electronic bike or save some money.

The best electric bike conversions kits allow you to covert any kind of bike such as; mountain bikes, commuter bikes or hybrid bikes into electronic bikes. These conversion kits also let you choose your motor and battery supply so you can be picky with your charging times and power preferences for a lesser price than buying a whole electric bike upfront.

Types of electric bike conversion kits

Conversion kits also come in three different options; Front wheel conversion kit, rear wheel conversion kit and mid-drive conversion kits. The front and rear wheel kits are usually cheaper and more suitable for commuting bikes or non technical terrains, the mid-drive units are slightly more expensive but are much better for converting mountain bikes and using on off-roading and incline situations.

Front wheel conversion kit

A front wheel conversion kit is a straightforward way to make your bike electronic just by replacing your front wheel with an electronic one. The kit should come with all the other basic components such as; an LCD screen panel, hub motor, battery, speed control, brakes and a throttle. Please make sure a sensor for pedal assistance is included if needed.

Rear wheel conversion kit

Rear wheel conversion kits are a more popular product of choice for electric bikes due to the fact they give more control and give an attractive design for the bike. Rear wheel conversion kits also nearly always have a pedal assist system which proves better than the front wheel conversion kits that only have a throttle. The kits for the rear wheel should have; a rear hub motor, battery, lcd display, electric brakes, speed control, throttle and pedal assist.

Mid drive conversion kit

Lastly, we have the mid drive conversion kits which are the best option if you are looking to convert an off-road bike/mountain bike. The mid drive conversion kits have the motor joined on the bottom bracket of the bike which balances it in the centre. The placement of this motor allows you to add in a torque sensor which can measure your effort and give motor assistance accordingly, giving you an overall smoother ride which is what you need on long adventures.

Mid drive conversion kits are often a little pricier and require a specific mountain bike frame to be installed on but are worth the investment if you are looking to convert a sturdy mountain bike into an electric one.

Now you may be wondering after covering the different type of conversion kits how you would even use/install one of these kits and what conversion kits are the best on the market?

Well, we are here to help you with that by reviewing the best bike conversion kits that are currently on the market so as you can be confident in your choice of conversion kit for your bike.

The Best Electric Bike Conversion Kits Compared

Now, let's get into our best rated electric bike conversion kits so as you can see what will suit you for your pending conversion.

#1 Bafang Mid Drive Electric Bike Motor Ebike Conversion Kit

The BBS02B Bafang mid drive conversion kit is the perfect kit for converting a mountain bike into an electric one. It includes all the basic mounting accessories such as; Bafang MM G340 48V 750 W Motor, brake levers which can be changed to hydraulic ones, LCD display with bluetooth function, pair of cranks, thumb throttle, speed sensor and more. This electric bike kit fits on bikes with a 68-73mm bottom bracket balancing the motor nicely in the centre.

The Bafang 750 watt motor provides a medium output of power and can reach speed of up to 24mph which is suitable for most riders. The central balance allows for extra stability and control, you can also choose to use the 9 pedal assist levels or thumb throttle (can also be changed to a twist throttle upon ordering) when riding giving you that extra assistance when needed. This kit does come without a battery however there are options to include a 48 v down tube or rear rack battery when making a purchase depending on what you would like.

Installation wise this bike conversion kit only needs a few tools to help remove the crankset, centre shaft and install the motor. Many YouTube videos can be found online to help and installation shouldn't take too much time.

Putting the Bafang mid drive conversion kit to the test

When testing this kit out I immediately notice the brands quality, Bafang is no stranger in the e-bike industry and I could notice how solid the components were made compared to other kits.  The installation process was pretty easy as long as you have the basic tools needed which can be purchased from any bike store easily or online.

When it came to riding the converted bike I noticed how powerful the motor was, no matter what incline I faced it was a breeze to ride, even on the lowest level of PAS you could feel the support giving you an overall more natural ride. The motor is also very quiet compared to others tested on this level before.

Overall the Bafang mid drive conversion kit is one of the best reliable rides I have tested, and can be installed very easily as you can even see from its raving reviews online. The only notable downfalls may be that there is more powerful motors on the market for mountain bikes if you have a higher budget and the battery does not come included.

To conclude, this is a reliable mid drive conversion kit which compared to others may be a little more expensive, but is a perfect choice for off-roading or shortening down daily commutes.

Pros

  • Reliable brand.
  • Powerful 750W motor.
  • Choice of battery.
  • 9 PAS levels.
  • Choice to include twist throttle.

Cons

  • Expensive.
  • More powerful motor options available.

#2 Junstar Bafang BBS02B Mid Drive Electric Bike Conversion Kit

The Junstar Bafang mid-drive electric bike conversion pack contains the Bafang products but the make is Junstar. The Bafang MM G340.750 make motor comes as either 350 W or 500W depending on your needs and can be fitted nicely on to your bottom rack. The bike conversion kits also come with the option of two different batteries; the Hailong battery or rear rack batteries, both Samsung made and comes as either 11.6 Ah or 17.5Ah. The 17.5 Ah battery can be fully charged within just 7 hours and can cover a distance of up to 60 km once charged, great for long adventures.

This product also includes the necessities such as; optional LCD screen with bluetooth, thumb throttle, pair of cranks, speed sensor, brake levers (hydraulic brakes can also be included on request) and an installation manual.

The best thing about this product is that it comes in different specifications depending on either your budgets or needs, for example, if your looking to take it off roading (it would be perfect for this) then you may go for a more expensive 500W motor paired with the 17.5Ah battery so as you can have more power on incline situations and be able to go for longer rides, however if you are looking for a daily commuter bike on a budget then a 350W and 11.6Ah battery would be a more cost effective option.

Riding with the Junstar Bafang bike kit

Installing the Junstar Bafang kit was easy due to there installation video and manual, we went with the 500w 17.5Ah rear rack battery and all parts seemed of high quality.

During riding the converted e-bike outdoors there was no problem on any off road surface or inclines, the whole ride felt very supported and the bike covered a large amount of range in a pretty short time. The motor was powerful and seems like a reliable choice if you are looking for a daily commuter ebike.

Overall, the Junstar Bafang ebike kit is pretty decent option compared to the other kits on the market due to it's different options available for a fair price.

Pros

  • Reputable Bafang brand.
  • Installation video available.
  • Mid-drive suitable for off-roading.
  • Different motor power and battery power available.

Cons

  • More powerful motors available for price.
  • Costly due to it being a mid-drive kit.

#3 Oukaning Speed Rear Wheel Electric Bicycle Motor Conversion Kit

This Oukaning electrical rear wheel bicycle kit can covert any bike with 26" wheels into an electrical bike. This product notably comes with; a powerful 1000 Watt 48 V motor, pedal assist system, electric brakes which shuts off the motor automatically to save energy and a twist throttle.

The electric motor included is pretty powerful compared to others electric bike conversion kits we have looked at considering the price, however this kit does not include an LCD screen and battery so you have to consider these extra costs too. The fact this is also a rear wheel unit may mean it isn't as suitable for off-roading as the mid-drive units above.

Testing out the Oukaning conversion kit

This kit overall was very easy to install onto our bike with a manual showing how to connect the right wires to the controller. When purchasing your battery you do need to keep in mind the power of the motor.

Riding wise this was a breeze to take out, the pedal assistance was little sloppy at some points but the throttle helped control it. It handled hills with pretty much no problem which is good if you are reluctant to invest in a more mid-range kit for your bike but still want an e-bike to take out on some more technical terrains.

Overall, the only downfalls to this conversion kit has to be that it doesn't include an LCD screen which is an important accessory for most bike conversion kits, once you add this cost in addition to a battery also, you could just pay out for a higher quality conversion kit.

Pros

  • Powerful 1000W motor.
  • Pedal assist included.
  • Manual included.
  • Can handle incline terrains.

Cons

  • No LCD screen.
  • Pedal assist can be slow at some points.

#4 ReaseJoy Front Wheel Electric Bicycle Motor Conversion Kit

This ReaseJoy 26" front wheel kit comes with a 36V 500w brushless gearless hub motor that can top speeds of 33KPH. It also comes with a dual mode controller which can allow the motor to continue working if the hall components inside the motor break down. The front wheel kit can easily fit on to a variety of different bicycles making it a more versatile option than other kits on the market.

This product can also come as rear wheel motor up to 1000w. It main components are; motor controller, electric brakes that shut off the motor, thumb throttle with 3 LED battery powered indicators, drive system without chains or gears so there is no friction and a strong aluminium rim. However it must be noted that there is no battery or lcd screen included. It also lacks the option to put hydraulic brakes and doesn't have a PAS system which could prove useful, but for the low price its a pretty good bargain still.

Is the ReaseJoy front wheel conversion kit worth it?

So, as there was not battery included with this kit we decided to use a 13Ah battery to pair with it. Installing the kit went smoothly although it must be noted that you may have to change some things around depending on the bike you have picked to covert, as for example we had to replace our front calliper and buy a torque arms to make this bike safe. Once installed, the e-bike ran very well and quietly assisted nicely over hills and inclines. It overall has a quality feel and gives enough help when riding combined with your own efforts.

There are some huge pros to this front wheel conversion kit such as; its price, versatility, quality and motor however there really is some extra expenses and issues to consider such as; lack of option to install hydraulic brakes if needed, a battery and pedal assistance system. This kit may also struggle to handle more complicated terrains and inclines due to it being a front wheel.

So to conclude, this is a good product but you may have to consider that once you add up the extras components it could be worth investing in a higher quality one with a more powerful motor.

Pros

  • Dual mode controller.
  • Low cost.

Cons

  • Low power motor.
  • No pedal assistance.
  • Front wheel may mean you need to be careful when choosing which model to install on.
  • Lack of option to install hydraulic brakes.

#5 HanSemay Rear Wheel Electric Bicycle Motor Conversion Kit

The HanSemay bike kit is strong rival to the Oukaning rear wheel kit due to it's matching motor power of 48V 1000 watts. This kit includes; 1000 W motor, front wheel, PAS, throttle and connectors. This kit does not include a battery or LCD screen similar to the Oukaning. Its nature of set up also means you have more stability.

The lack of an LCD screen can be bought and installed however you will need another controller to do this which can add up another expense.

Testing out the Hansemay rear wheel kit on the road

First thing we noticed about this product was that for the price, everything was of good quality and included everything you need for an electric bike minus the LCD screen and battery. This installation was easy to do and took a very small amount of time compared to other products we have tested. When riding out with our electric bike kit the motor made a mid-range level of noise and could reach top speeds of 30 mph easily even on the most difficult of inclines, which is pretty good considering we would class it as more of a commuter bike.

Overall considering it has everything the Oukaning has at nearly the half the price, this is definitely a budget option to consider, although the absence of a battery and LCD display along with another controller for it, is an additional cost.

Pros

  • Powerful 1000W motor.
  • Easy installation.
  • Rear wheel.
  • Low price.

Cons

  • LCD display needs purchasing with a different controller.

Final Judgement

So now we have listed out our top choice electric bike conversion products, you can see our top rated has to be the Bafang BBS02B Mid Drive Electric Bike Conversion Kit. This is the best electric bike conversion kit purely down to the make and quality of the product, although it may be more expensive than others. If you can afford this mid-drive electric bike conversion kit it will not disappoint.

If you are looking for the best electric bike conversion kits for you then it really comes down to your personal preference, budget and what you want to use your bike for. For example, if you are looking for a daily commuter bike on more of a budget then the Oukaning rear wheel kit may be for you, as you don't need too much power to ride with but it still comes with all the important accessories such as pedal assist. An even more budget option could be the Reasejoy front wheel conversion kit however this does come without a pedal assist system which may be an issue for some riders.
