In fact, the market is currently filled with plenty of these bike conversion kits that even making the right choice can prove to be difficult.
To help you out, this no-nonsense guide, is going to take you through all that you need to know about electric bike kits. Let’s get started!
What is an electric bike conversion kit?
An electric bike conversion kit is a small engine that can be attached to your bicycle to make your biking smoother and faster. The kit comes with a drive unit that is to be attached to either the front or rear wheel, but some can be attached at your bike’s bottom bracket. That aside, the motor is powered using a battery (usually lithium), and the kit also comes with an LCD display panel, speed controller, throttle/brakes, wire harness, and a pedal assist.
In fact, electric bike kits are not hard to install, so you have nothing to worry about. All in all, you’ll get to keep your original, old bike while at the same time saving a significant budget that you would’ve used to purchase a new e-bike.
Types of electric bike conversion kits
Generally, electric bike conversion kits are of different types depending on your bike and how you’ll be riding. Most motors are built to be placed on one of your bike’s hubs or the frame’s center. Here’re the two main types drive units:
If you intend to do simple commutes, road riding, or mountain biking, then hub motors are tailor made for you. Below are the main types of hub motors you should know about:
• Front hub conversion kit: This is the most common and the cheapest of them all. In addition, it’s quite easy to install and it doesn’t require any special tools to install. You simply have to replace your bike’s front wheel with the one in the kit, and then proceed to run the wire to the controller. However, it’s best suited for simple commutes and road riding.
• Rear hub conversion kit: Just as the name suggests, this kit is normally placed on your bike’s back tire. Although it’s quite similar to the front hub kit, the rear hub conversion kit is better because of the less distance between the rear rack and the hub, meaning you’ll use less wire. Another advantage of using rear hub motors is that they’re quite powerful, making them ideal for mountain biking and off-roading.
• Friction drive conversion kit: All that such a kit has to do is to push the wheels along. In fact, the installation process of this kit is super-easy, but they are not that helpful during wet seasons. This is because when your tires’ rubber gets wet, they become slippery. Therefore, without any friction, there’s no electricity to move your electric bike.
In the mid-drive electric bike system, the motor is placed at the center of the bike’s frame and integrates with the cranks and bottom racket. In addition, the motor is normally activated by pedaling, so a mid-drive system is generally pedelec. That aside, the mid-drive system comes with lots of advantages compared to the hub motor.
To begin with, you’ll get more torque/power with a mid-drive system, and because it’s centrally located, weight is distributed more evenly giving you more balance. On the flipside, you’ll definitely require specialist tools to install this system, and you’ll also have to pay more.
What type of battery do electric bike kits use?
Most electric bike kits don’t come with a battery. Surprised, right? Well, before you start complaining about this minor inconvenience, think about the advantages that come with choosing an e-bike battery by yourself. With that in mind, here are some of the things you should consider when choosing quality e-bike battery:
The amp simply means the capacity of the battery, which can determine how far you can enjoy your ride with one charge. The recommended measure for your e-bike conversion kit should be at least 20Ah or less. However, be careful not to go for a much higher capacity because a higher capacity means a heavier battery. I’m sure you don’t want this, do you?
Normally, your e-bike will be fine with 12V, but you might find some using 72V. Of course a higher voltage translates to a higher speed and power, but you’ll still be fine with something less than 24V. However, if you will be covering long distances or tough terrains, you can go for something between 38-48V, but in this case you’ll have to pay a little bit more.
Like with electric scooters, you’ll probably come across motors with 250W, 500W, 750W, with some of them even going as high as 1500W. In simple terms, this refers to the motor’s power output. So the more the wattage means more power produced, hence the need for a bigger battery.
Now that you already know the basics of an e-bike kit, it’s time to take you through some of the best kits currently available in the market.
