Price Comparison of Popular Conversion Kits (2025)

Average Cost of an Electric Bike Conversion Kit

If you’ve looked around, you’ll notice conversion kit prices are all over the place. Some budget kits cost just a few hundred dollars, while premium or high-powered options can climb well over a thousand. The good news is that you don’t need to spend top dollar unless you really want extreme performance.

On average, most decent conversion kits fall between $500 and $1,200. At the lower end, you’ll find basic hub motor kits that are easy to install and perfect for casual rides. In the mid-range, usually $700 to $1,000, you get more reliable motors, bigger batteries, and smoother riding experience. At the top end, premium and high-torque kits often go past $1,200, especially if they’re built for fat tire bikes, mountain trails, or extreme speed.

Here’s a quick way to think about it:

• Budget kits (~$500–$700): Best for short city rides and casual riders.
  
• Mid-range kits (~$700–$1,000): A good balance of performance and price.
  
• Premium kits ($1,200+): Built for off-road, hills, and riders who want more power or longer range.

What Affects the Price of an E-Bike Conversion Kit

Not all electric bike conversion kits are priced the same, and for good reason. The cost depends on several key factors that can quickly raise or lower the price tag. Understanding these will help you figure out why one kit costs $500 and another might be closer to $1,500.

Motor type

• Hub motors are usually the cheapest and simplest. They’re perfect for flat roads and everyday use.
  
• Mid-drive motors cost more because they deliver stronger torque, making them ideal for hills and mountain trails.
  
• Friction drive or rim drive systems are less common but can be either very affordable or on the higher end if built for performance.
  

Battery capacity and voltage

The battery is often the single most expensive part of a kit. A bigger battery means longer range, but also higher cost. For example, a small 36V pack is cheaper than a high-capacity 72V pack used in extreme power kits.

Brand reputation and support

Well-known brands like Bafang, Swytch, or Kirbebike sometimes charge more, but you also get better support, warranty, and peace of mind.

Accessories and add-ons

Some kits include extras like LCD displays, throttles, or torque sensors. These features improve your riding experience but also add to the overall price.

How Much Is a Swytch Electric Bike Conversion Kit

The Swytch conversion kit is one of the most talked-about options because it’s compact, beginner-friendly, and more affordable than many others. If you’re new to e-bike conversions, this kit often comes up as the first recommendation.

Swytch currently offers two main battery options:

• Swytch Eco Pack – priced around $999 USD, it gives you a smaller, lightweight battery perfect for city commuting and shorter rides.
  
• Swytch Pro Pack – priced closer to $1,199 USD, it includes a larger battery that can handle longer rides and provides more range before recharging.
  

Both versions come with the same front hub motor, which means the main difference you’re paying for is range. The Eco pack is great if you just need quick rides around town, while the Pro pack makes more sense if you plan to cover longer distances or want fewer charging stops.

Extra Costs to Keep in Mind

The price of the kit itself isn’t always the final bill. There are a few extra costs that can catch you by surprise if you don’t plan for them. Knowing these in advance will help you budget properly.

Installation

If you’re handy with tools, you can install most kits yourself for free. But if you’d rather leave it to a bike shop, expect to pay anywhere from $50 to $150 depending on the complexity of the kit. Mid-drive systems usually cost more to fit than simple hub kits.

Shipping and taxes

Some brands, especially those shipping internationally, may add extra charges for delivery and import taxes. It’s worth checking these before you hit “buy” so you don’t end up with an unexpected bill.

Upgrading bike parts

A powerful motor puts more stress on your bike. You may need stronger brakes, a new chain, or even reinforced wheels. These upgrades aren’t always required, but for high-power kits like Kirbebike’s 2000W or 4000W models, they’re highly recommended.

Adding these costs to your budget ensures your bike not only performs well but also stays safe and reliable.

Is a Conversion Kit Cheaper Than Buying a New E-Bike?

This is probably the biggest question most riders have before making a choice. A brand-new e-bike often costs anywhere from $1,500 to $4,000, depending on the brand and specs. That’s a serious investment, especially if you already own a bike you love riding.

A conversion kit, on the other hand, can cost as little as $500 for a basic hub system and usually stays under $1,500 even for premium or high-powered options. In many cases, that’s half the price of buying a new e-bike, and you still get to keep your familiar frame and setup.

Of course, there are exceptions. If your bike is old or not in great condition, putting money into a conversion kit might not make sense. But if your bike is solid and you simply want the boost of electric power, a kit almost always works out cheaper and smarter than starting over with a brand-new e-bike.

Tips for Getting the Best Value

Spending smart is just as important as spending less. The right tips can save you money and help you pick a kit that actually fits your riding style instead of just looking good on paper.

Buy direct from the brand

Going straight to the manufacturer often gets you the best price and warranty. Brands like Swytch and Kirbebike regularly run promotions on their official sites.

Look for seasonal deals

Many brands offer discounts around holidays or launch events. Signing up for newsletters is a good way to catch these sales before they disappear.

Match the kit to your riding needs

If you only ride short city routes, a lightweight kit like Swytch Eco is more than enough. If you plan on mountain trails or off-road, investing in a mid-drive or a Kirbebike high-power kit makes more sense.

Check the warranty and support

Paying a little more for a brand that offers strong support and warranty can save you a lot in the long run.

By focusing on value instead of just price, you’ll end up with a kit that lasts longer and gives you the best ride for your money.

Final Thoughts

Converting your bike into an e-bike is one of the easiest ways to enjoy more speed, longer rides, and effortless hill climbing without spending thousands on a brand-new model. Kits range anywhere from $500 for entry-level options to over $1,800 for high-powered builds like Kirbebike’s extreme performance models.

The right choice really comes down to your needs. If you just want a lightweight boost for short commutes, a kit like the Swytch Eco will do the job. If you need more power for trails, a mid-drive kit from Bafang or TongSheng gives great balance. And if you’re chasing speed and torque, Kirbebike’s 2000W or 4000W kits deliver unmatched performance.

I’ll leave you with this: don’t just shop by price alone. Think about how you ride, what your bike can handle, and how much support you want from the brand. Once you figure that out, picking the right kit becomes simple.
