Electric bicycles have skyrocketed in popularity over the past years — and the trend shows no signs of slowing, with the global e-bike market estimated to reach $80.6 billion by 2027.

If you’re curious about e-bikes but aren’t yet ready to commit to buying one, an e-bike conversion kit is the answer. E-bike conversion kits let you convert a regular bike into an electric bicycle. It’s a cost-efficient way to give an e-bike a try.

There’s a variety of e-bike conversion kits on the market. Before you create your DIY e-bike, though, do your research: You want to spend your money wisely.

The good news? We’ve done the research for you. Read on to learn what to look for in an e-bike kit and some of the best e-bike conversion kits.

What To Consider When Choosing an Electric Bike Kit

If you’re considering getting an electric bike conversion kit, be aware: All conversion kits aren’t created equal. Educating yourself about the key characteristics of e-bike kits can help you avoid wasted cash. Keep these points in mind.

Compatibility With Your Bike

Not all e-bike conversion kits fit all kinds of bikes. Most conversion kit manufacturers include specifications to help you determine if their product is a match for your ride. 

These specs might address your bike’s:

  • Wheel size and rim size
  • Brake type (for example, disc brakes versus rim brakes)
  • Cassette and freewheel type (parts of your gearing system)
  • Rear frame stay width (the part of the frame that secures the rear wheel)
  • Front fork/shocks width (the part of the frame that secures the front wheel)

Also, note there are different e-bike conversion kits: friction drive conversion, mid-drive conversion, and e-bike wheel conversion.

Most cyclists prefer mid-drive, because the conversion kit is secured low to the frame, enhancing balance. Also, the motor applies power to the crank arms (the part of the bike that connects the pedals to the chainrings). This creates a smoother ride.

Power and Performance

E-bike conversion kits differ in motor power and battery capacity, impacting your riding experience — notably top speeds and how far you can go. 

Manufacturers measure motor power in watts. Standard choices for wattage for e-bike conversion kits include 250, 500, 750, and 1,000 watts. The higher the number, the more powerful the motor.

Be aware that a higher motor power will drain the e-bike battery faster. This reduces the bike’s range, or how long you can ride before the battery pack drains and you must recharge. Manufacturers measure battery capacity in watt-hours.

Budget and Value

Let’s be realistic: Price is a factor when investing in an e-bike conversion kit! Although conversion kits are cheaper than fully electric bicycles, they’re still an investment.

The good news? There are e-bike conversion kits for all kinds of budgets. You can expect to pay anywhere from a few hundred dollars ($300) to $1,500 or more — the below list offers a sampling of price points.

When buying an e-bike conversion kit, look for manufacturer rebates to cut costs. Also, some states offer tax rebates and credits for e-bike purchases — a good tip to keep in mind if you enjoy the conversion kit and want to buy an electric bicycle later.
