Top 5 Electric Bike Conversion Kits
E-bike kit on bicycle.Looking for an electric bike kit requires serious thought and research on your part. There are a lot of great options out there, so it can be hard to figure out which one is the best for your bicycle and, even more importantly, for you. That’s why we set out to find the best e-bike kits around — so you can find the right upgrade for your ride. In this article, we’ll take a look at the top 5 e-bike conversion kits of the year. Before we go into the specific kits, though, let’s delve a little deeper into what makes these e-bike conversion kits so great.

What Is an Electric Bike Kit?

Front wheel e-bike kit installed on a bicycle.An electric bike kit — also known as an e-bike kit or e-bike conversion kit — is essentially an electric hub motor that can transform a regular bicycle into an e-bike. Typically, an e-bike kit consists of three key components:
  1. Electric Wheel/Mid Drive Motor — This contains the motor that propels your bike forward.
  2. Battery — This is what stores the energy used by the motor to help you ride.
  3. Pedelec — This is what helps read the cadence of your pedals while you're pedaling, sending a signal to your motor to help assist your ride as much or as little as you prefer.
Of course, you also receive everything to make the kit run, as well. This includes the controller that regulates the energy going to all parts of your bike; throttle components; and accessories like a speedometer. The components in an e-bike conversion kit are the same ones you'll find on any electric bike out there, from the high end models to budget bikes. The difference, of course, is that instead of purchasing a complete e-bike, you get everything you need to make one yourself out of the bike of your choice.

Why Should You Install an E-Bike Kit on Your Bicycle ?

ModWheel mid-drive motor installation.So who, exactly, are electric bike conversion kits for? Well, anyone, actually! An e-bike kit is a great way to upgrade your current bicycle. Here are some of the reasons so many bike riders prefer e-bike kits:
  • Pedal Assistance While Riding — If you’re cruising around town or going for a daily bike ride, you may want to ease the intensity a bit. E-bike kits don't remove your ability to pedal, so if you want some assistance while riding, these kits are a great upgrade.
  • Climbing Hills — Steep hills can be a challenge for even seasoned bicyclists. As such, an electric bike kit is a great way to ease into tackling those inclines. These kits are especially great if you have a long trip with multiple hills to look forward to.
  • Commuting — Maybe you just need to get to work, school, or your local coffee shop. Installing an e-bike kit on your bicycle essentially turns it into a daily commuter. Plus, conversion wheels are eco-friendly, so you’re doing your part to help the environment.
  • Off-Roading — If you want to take your mountain bike to the next level, a high-powered e-bike conversion kit is a great way to turn your basic ride into an electric dirt bike. With the proper kit, you’ll be able to take on off-road terrain with plenty of power and control.
  • Customization — Who doesn't want a bike that's 100 percent their own? While e-bike styles may vary, there's no denying that the majority of them look similar. With an electric conversion kit, the sky's the limit! You can take your favorite bike, match the wheel sizes, install, and in less than an hour you have a fully-loaded e-bike you don't have to break in or get used it.

For example, if you're not mechanically inclined, mid-drive conversion kits like the ModWheel 48V 500W Mid Drive e-bike kit won't be the best option as they require you to swap out the cranks on your bike. If you're not up for the challenge of putting your own electric bike together, you may want to consider purchasing a preassembled electric bike. However, if you've got a moderate-to-good knowledge of changing the wheels on your bike and/or know how to change the cranks on your bicycle, there's no reason to not use a conversion kit (unless you want to spend lots of money on an e-bike).

Types of E-Bike Conversion Kits

ModWheel Mid-Drive E-Bike Kit on bike.As you've probably seen in your research, there are quite a few electric bike conversion kits out to choose from. Not just in terms of brands, but how they run. Here are some important aspects to pay attention to when shopping for an electric bike kit:
  • Hub Drive — This type of e-bike kit motor powers either the front or rear wheel of your bicycle. The motor is attached directly in the hub of the wheel.
    • Front Wheel vs. Rear Wheel — Front wheel e-bike conversion motors are great for acceleration and flat terrain. Meanwhile, rear wheel motors give you solid torque and better performance on off-road terrain and hills.
  • Mid Drive (aka Center Drive) — Aside from their lightweight design and discreet size, mid drive motors give your bike some great torque. This type of e-bike kit is great for climbing especially steep hills with ease.
  • Geared Hub — A geared hub consists of multiple rotating gears. These gears spin rapidly to power the motor while making the most of their energy consumption.
    • Geared motors are able to give you high levels of torque. On the flipside, though, top speeds aren't very high.
  • Brushless Hub — A brushless hub doesn't include gears but rather a stator and rotor. These components take your e-bike kit battery's energy and use it to power magnets that spin the wheel.
    • Brushless hub motors are capable of high speeds. They're also much quieter and longer-lasting than geared hubs. That said, while capable of decent distances, their range suffers in stop-and-go traffic situations.

  • Wattage — This is the overall power output of a motor. The more watts a motor is capable of putting out, the more power (in speed and torque) the motor can handle.
  • Voltage — This is the the power it takes to run your motor. The voltage of a motor will let you know how much power it'll take to move you and your bike.
  • Amperage — This is a representation of the total amount of power that can be used with a given battery and motor setup. Think of this sort of like a fuel tank, in that the higher the amperage, the higher potential there is for more power.
Bicycle with e-bike kit.These three elements work together to give you an understanding of the power and potential of an e-bike kit. Let's break down the ModWheel 36v 250w 26 Inch Geared Front Wheel Electric Bike Kit, for example:
  • This motor needs a 36 volt battery to power the 250w motor.
  • With a 36v battery, this motor will be capable of putting out 250 watts of power through its motor.
  • The compatible battery is made to power 36 volts at 11 amps.
