Beginner’s Guides to E-bike Conversion Kits

What is an E-bike Conversion Kit?

An e-bike conversion kit allows you to transform a regular road bike into an electric bike by replacing either your tires or pedals with a motorized hub without spending a few thousand dollars to purchase a factory-built e-bike. Although, compare electric bikes vs conversion kits before deciding on what to buy. And, if you find that a new ebike would suit you better, then you’ll want to check out our roundup of the highest-grade front-drive electric motor bikes.

The main component of an electric bike kit is a motor that can either be attached between the bike’s pedals (mid-drive motor) or at the front/rear (hub-drive motor). The battery is equally essential for an e-bike to function. Still, not all conversion kits include batteries and, therefore, may need to be bought separately.

An E-bike Conversion Kit vs Other Electric Bikes

If purchasing a brand new electric bike is heavy on your wallet, you can readily upgrade the road bike sitting around in your shed to an e-bike with an e-bike conversion kit. Most factory mid-drive electric bikes will cost you nothing less than $2000, while a DIY e-bike can be built for less than $500 if you already own a bike or $1200 if you buy a new road bike.

Additionally, you’re also doing the environment a favor by choosing a green alternative to carbon-emitting cars. You’ll have an affordable electric motor facilitating your pedaling efforts so that you’re not gasping for breath during your commute.

With an e-bike kit, you can build an e-bike based on your specific requirements. This way, if you prefer taking your converted electric bike on hilly trails, you can pick out a specific kit that includes a mid-drive motor, as these are better suited for inclined surfaces. Plus, you always have the option to swap out the conversion kit for a new bike. An expensive factory e-bike, on the other hand, isn’t easily upgradeable. But at the same time, nothing can replace the high-level performance that a manufactured electric bike provides.

There are a few downsides to an electric bicycle kit as well. Mechanical competence is a major requirement if you’re planning on converting your bike yourself, which is not something you’d have to worry about with a store-bought ebike.

A store-bought model is going to look sleek and stylish right from the start, and you’ll be ready to hit the pavement immediately. That’s not the case with a DIY ebike. Attaching the motor and battery may take a few hours, if not a whole day. And, too, your converted bike will never resemble a factory-built e-bike as there are a lot of wires that come with these kits. They have to be run along the outside of the frame, giving your bike a DIY look.

Fortunately, today, with a growing number of bikers opting for e-bike conversion kits, some companies have begun to specialize in bike conversions, so you don’t have to get your hands dirty.

How an Ebike Conversion Kit Works

Chances are that if you have a pedal-powered bike, you can easily convert it into an e-bike with a conversion kit that either incorporates a rear hub motor or a mid-drive system.

A mid-drive conversion kit’s motor is attached between the pedals, right in the middle of your traditional bike. This gives you a well-balanced riding experience and is most suitable for off-roading and other steep climbing tracks. Another significant advantage of these motors is that they offer more torque without expanding the battery’s capacity.

However, a mid-drive conversion kit is the more expensive option of the two kits. These bikes are quiet and run smoothly. At the same time, they can be tricky to install if you’re not mechanically adept. The bottom bracket must be deftly removed for this driving system to be installed correctly. Note that there will be only one chainring on the front of your bike after the conversion. Moreover, bikers complain of cycling resistance when the motor’s turned off because the clutch disengages, transferring the pedal power from your feet to the chain.

On the other hand, a hub-drive motor is affordable and comparatively easy to install, becoming an excellent option for your daily commute. But it’s important to note that hub-drive motors are bulkier and sit either on the front or rear wheel, making your ride slightly off-balanced.

Both the kits will comprise a battery, pedal sensor, display, wiring loom, and controller. However, you may have to purchase a battery and/or the wheel separately for some kits.

Why should you buy an E-bike Conversion Kit?

It’s common knowledge that, in the USA, e-bikes are becoming a frequently chosen mode of transport. But, the hefty price tag that comes along with these bikes deters many people from buying them. That’s where e-bike conversion kits come into the picture. So, if you’re looking to cut down your carbon footprint but don’t want to pay an exorbitant amount for a new ebike, a conversion kit is a great option.

Are E-bike Conversion Kits Worth Buying?

  • You Own a Decent Bike: If you have a decent enough road bike that you’re not willing to part with, you can give it a complete makeover with the correct e-bike conversion kit.
  • You Can Save Money: As mentioned above, a premium quality e-bike will cost you $2000, but you can save around $1000-$1500 by opting for an e-bike conversion kit (that is, if you already own a traditional bike). However, the total cost of buying a new traditional bike and a kit will still be less than an electric bike.
  • You Want to Reduce Your Carbon Footprint: E-bikes and conversion kits are both a green alternative to carbon-emitting vehicles and will go a long way in preserving the environment.

Why E-bike Conversion Kits May Not Be for You

  • You Don’t Prefer the DIY Look of Your Bike: Since conversion kits have external wiring that may extend throughout the length of your converted bike, it may never acquire the professional look that the best throttle electric bike displays. That said, a mid-drive conversion kit can still bring your bike’s overall appearance close to a factory-made e-bike.
  • You Don’t Have Mechanical Competency: The hassle of converting a bike yourself can prohibit bike owners from opting for an e-bike conversion kit. But you’ll find many companies today that’ll convert your bike for you.

How Long Will an Ebike Conversion Kit Last?

The lifespan of your e-bike conversion kit ultimately depends on the performance of your battery life and how well you maintain the motor. Generally, a converted e-bike will last for three to five years before its battery needs to be replaced.

Certain maintenance tips can extend both the battery and motor life. First of all, keep the batteries cool and away from sunlight, and remember never to cover the batteries when they’re charging. Plus, if your battery is out of charge, don’t leave it that way. This will lead to a reduction in its efficiency. A 40% to 80% charge range is ideal.

Hub motors that sit at the rear end may exert too much force on the spokes, causing them to break. But spoke tension can be kept in check with regular servicing. Similarly, a mid-drive motor may put excess pressure on the chain. For this, you will require a chain cleaning tool and a degreaser for it to function smoothly.

Lastly, check the wiring as it’s essential to keep your e-bike running. Since the wires are on the outside of converted e-bikes, you have to be extra careful that they don’t get caught in your car’s bike rack while mounting/unmounting.

How to Choose the Best Ebike Conversion Kit

Before you choose an e-bike conversion kit, bear in mind that it may change your bike’s entire aesthetic and increase its weight. Likewise, there are many other factors to consider, from the bike’s frame material to your budget.

E-bike Conversion Kit Key Factors

1. How Much Power Does Your E-bike Require?

When picking the right wattage for your converted e-bike, you’ll want to consider your weight and the terrain you’ll traverse on. If you regularly move on inclined roads, 250W power will not suffice. You may need to upgrade to 350W or 500W for uphill rides. But, at the same time, it’s not recommended to have 1000W power either as you may hit illegal speeds. Standard laws cap motor power at 500W.

Additionally, you’ll need more power to accelerate your bike if you’re a heavy biker. While a biker weighing 110 lbs will be comfortable with a 250W bike that’s ridden on a flat surface, bikers weighing over 220 lbs may require a 750W e-bike for flat surfaces and a 1000W model for steep inclinations.

2. What Kind of Bottom Bracket Does Your Bike Have?

The type of bottom bracket your bike has determines whether you should select a mid-drive or hub motor conversion kit. Ideally, if you’re looking to attach a mid-drive, you must have a standard threaded bottom bracket shell that’s 68mm-73mm wide. But with a press-fit bottom bracket, it’s best to choose a hub motor. Most hub motors come equipped with a pedal sensor that can be fitted to a square-tapered cartridge bottom bracket (on the non-drive side).

3. What Type Of Sensor Should It Have — Cadence or Torque?

E-bike conversion kits come with either a cadence or a torque sensor, and you can choose which one suits you best based on your pedaling style. With cadence sensors, the faster you pedal, the more power you derive from the motor. You can find these sensors with hub-drive motors. Unlike cadence sensors, torque sensors measure how hard you’re pedaling and are commonly used in mid-drives.

4. How Much Additional Weight Can You Handle?

It’s important to note that the transition from a regular road bike to an e-bike means your 22-lb bike now suddenly weighs 38 lbs. This is primarily due to the additional weight of the battery and motor. Even if you purchase the lightest conversion option in the market, your bike will still be heavier than it was.

With batteries, you may have to find a balance between range and weight. Longer-range batteries of 36v 20Ah weigh close to 9 lbs and are considerably heavier than shorter-range ones.

5. What Frame Material Is Your Bike Made Of?

Most road bikes weren’t specifically designed to take on the extra weight of an e-bike conversion kit. Therefore, it’s essential to consider your bike’s frame material.

There are three main types of frames — steel, alloy, and carbon frames. Of the three, the steel frames are your best bet as steel is durable to carry additional weight. But the total weight after the kit has been attached may be more because a steel frame in itself is heavy.

Alloy frames are found on cheaper bikes and work pretty decently for the first 2000 miles, but eventually, you may find the wheel pops out of the dropouts.

Lastly, if you have a few extra bucks to spend, a carbon frame is worth it. It’s much lighter compared to steel frames and resists corrosion better. One major limitation with these frames is that due to the nature of the material, it can easily hide defects after a heavy crash, proving to be a safety hazard in the long run.

6. What’s Your Budget?

You can expect a price range between $200 to $500 for an e-bike conversion kit that includes the wheel and electrical components. Make sure the wheel is compatible with your road bike. Going up the price range ($500 and up) means you’ll find top-notch conversion kits with powerful motors and durable batteries, just like the best battery for electric bike.

In your search for e-bike conversion kits, there will be plenty of unknown brands that you may stumble across. It’s important to remain open-minded to names you’ve never heard of because they might just be a well-established brand from a different corner of the world.
