What To Look For In a Bafang E-Bike Conversion Kit (Our Buying Guide)

After comparing both the BBS02 and BBSHD conversion kits it's a good idea to get a little more clued up on what you need to look for inside of your conversion kit as well as how to install one properly if you first time. 

Benefits Of Choosing An E-Bike Conversion Kit 

E-bike conversion kits can be a little complicated as you have to understand motor efficiency, battery voltage and watts difference, but finding the right conversion kit for you can be much more rewarding than buying an electric bike upfront with many advantages we will list below. 

  • You get to use your bike - One of the main advantages to installing an e-bike conversion kit on your bike is that you get to stick with your favourite bike which you find comfortable to ride with, as long as your bike is sturdy and has good brakes you should be good to go!
  • It saves money - Although electric bike conversion kits can become pretty expensive once you add in the battery they will save you a few hundred £100 than buying an electric bike upfront. 
  • You have more space - Rather than buying another bike, converting your older one allows you to save on space, having a conversion kit on your original bike will not make it any bigger, but maybe slightly heavier.
  • It can be customised - The best part about e-bike conversion kits is that you can pick and choose what you want in your kit, choosing assistance, sensors, controllers and accessories you can make the exact type of electric bike that you want.
  • You can bring an old e-bike back to life - If the motor or batter has failed on your old electric bike you can bring it back to life by installing a new conversion kit rather than wasting a whole e-bike. 
  • It's fun - For anyone who likes a bit of DIY and challenges then installing your electric bike conversion kit can be a pretty fun task.

Drawbacks Of An E-Bike Conversion Kit 

Although there are many advantages to an e-bike conversion kit there are also some negatives to consider before you invest in one. 

  • It might not be suitable - You have to ensure that frame of your bike will be able to handle the weight and power of an e-bike conversion kit, some bikes are not durable enough for this.
  • You might need a professional - Installing an e-bike conversion kit is not as simple as it seems, you need to have a bit of background knowledge to be able to do it, if not you might have to pay out for a professional.
  • They don't have long term durability - Compared to a standard premade e-bike these conversion kits do not have as long term durability as this is not what they were designed for.

Features To Consider In An E-Bike Conversion Kit

Choosing the right kind of e-bike conversion kit can be a little overwhelming with all their different features, we have listed the most important ones for you to watch out for in your kit below. 

  • Type of motor power - When choosing your e-bike conversion kit you should ensure that the types of motor you choose are brushless as they are much quieter and give high performance.
  • Motor wattage - Always ensure that your motor is high enough in power for your needs, if you need a road legal motor then pick a 250W motor in your kit, however mountain biking or trail riding 750W motors might be more desirable due to the extra power.
  • Motor position - The excellent mid-drive motors we reviewed above both come with a mid-drive position which gives ultimate power and balanced assistance when riding due to its more natural position. You will also find the front hub and rear hub motor kits, front hubs are cheaper but easy to do although they give more unnatural assistance, rear hubs are great for converting commuter bikes.
  • Components - Your electric bike conversion kit will come with a variety of different components, from controllers to chains. For example, the BBSHD motors kit comes with brake levers, an LCD, throttle, crank wheel, chains, speed sensors and even headlights. The amount of components you have the better value for money your kit is.
  • Ease of installation - Make sure your e-bike is easy to install with clear instructions, brands such as Bafang are well known to have easy installation for all their conversion kits and even offer video installation to make the process more simple.
  • Battery - Some e-bike conversion kits include a battery while others require you to purchase it separately, you should account for this extra cost and also ensure that the battery selection of the conversion kit matches your motor power to make sure there is enough range.
  • Warranty - Always make sure your e-bike conversion kit has a warranty on the motor and its components to ensure you are choosing a reliable model.
