This motor has 500 watts to drive enough power to the wheels for climbing up hills and overcoming resistance on a windy day. Its brushless design makes the motor a quieter and more efficient alternative to a brushed motor. Brushless motors also require less maintenance over time, which is good news for your wallet.

    With a top speed of 17 miles per hour, it’s not quite as quick as some other kits on our list. This set provides up to 21 miles at a time, so you can run errands and commute to work on a single charge.

Are eBike Conversion Kits worth It?

If you want to breathe new life into an older bike or are looking for a cheaper alternative to purchasing a shiny new electric bicycle, an e-bike conversion kit is definitely worth it.

Maybe you have an old bike (or two) lying around that you just can't bring yourself to part with, or you're intrigued by the thought of trying out the power of an electric motor without the potentially high upfront cost of an e-bike. Or, you've struggled to find a good alternative and want the most powerful electric bike conversion kit for your money.

Either way, electric bike conversion kits give you the flexibility of choosing which bike you want to use along with the type of kit that works best for you and your bike. 

There is no standard for installing an e-bike conversion kit, so you'll need to decide whether you want a rear-wheel kit or a front-wheel kit. Both options involve removing the existing tire and replacing it with the motor and any necessary components, such as a crank arm or a speed sensor. 

Some electric bicycle kits are easier to install than others, especially if you have some previous experience working on a bike. Don't worry if you're not mechanically inclined, however, as most conversion kit enthusiasts are able to make it through the installation process without issue.

Which Are the Best E-bike Conversion Kits?

Generally speaking, the more you spend to get an e-bike conversion kit, the more power and performance you can expect. You don't need to splurge on the most expensive electric bicycle kit available, however, as the best e-bike conversion kits largely depend on your bike, riding habits and the amount of riding you'll be doing. For example, if you typically use your bike for shorter rides, you can get away with less power and performance. 

According to Easyebiking.com, you can get an e-bike conversion kit with 350 watts of power and a 10Ah (ampere-hour) battery for shorter distances.

If you frequently head out on longer rides or often find yourself riding over rougher terrain, such as mud and rocks, you might want to consider an e-bike conversion kit with 500 to 750 watts and a 40Ah battery.

Aggressive riders seeking to transform an existing bike into a premium electric mountain bike will want higher-end kits that offer the necessary power and capabilities. If you're shopping for the most powerful electric bike conversion kit, ModWheel 48V 1000W Direct Drive Front Wheel Electric Bike Kit & Optional Battery.

Can You Turn a Regular Bike Into an eBike?

With the right kit, you can convert many different regular bikes into electric ones.

Front hub conversion kits tend to be the more popular and more affordable type of e-bike conversion kit. One of the biggest draws of a front hub conversion kit is that it often doesn't require special tools for installation.

To properly convert your bike, you often simply need to remove the front wheel, replace it with the one in the kit and set up the wire from the hub to the controller to complete the installation.

On the other hand, rear hub conversion kits can be trickier to install. However, fans of rear hub kits praise the rear placement because it provides a more balanced ride and doesn't require you to use as much wire. 

Another option is direct drive to the rear wheels. According to WheelsGo, the advantage of this setup is that it can be more efficient overall, as the electric motor is bolted onto the frame, with a chain running to the rear wheel.

Most of these types of e-bike conversion kits are also affordably priced. However, they can be bulky and tricky to assemble.

How Much Does It Cost to Convert Your Bike to Electric?

On average, you can expect to spend between $300 and $1,000 for an e-bike kit. This wide price range reflects the type of kit as well as the motor and additional accessories.

The most powerful motors with 1,000+ watts are often the priciest. If you don't need that much power, you can potentially save hundreds of dollars by choosing a smaller motor.
