How this e-bike scores for different riding styles

High Performance
82/100

The 1000W motor and 48V system deliver strong performance well above average conversion kits. However, maximum speed specifications aren't provided, and performance depends on the base bike quality.

Recreational Leisure
75/100

The 9 levels of pedal assist and throttle option provide versatile control for casual riding. The LCD display and smooth power delivery make it enjoyable for leisure rides.

Daily Commuting
72/100

The 1000W motor and pedal assist make it capable for commuting, but as a conversion kit rather than complete bike, it requires installation expertise. The included battery provides decent capacity for urban commutes.

Off-Road Adventure
68/100

The powerful 1000W motor and 80NM torque provide excellent hill-climbing ability for trails. However, it lacks suspension and depends entirely on the base bike's frame durability for off-road use.

Cargo & Utility
60/100

The 1000W motor has sufficient power for hauling loads, but the kit's suitability depends entirely on the base bike's frame strength and cargo capacity, which isn't included.

Compact & Portable
25/100

As a mid-drive conversion kit, it adds permanent weight and components to the bike frame, making it unsuitable for portability. No folding capability exists.

Our Verdict

This Bafang conversion kit turns your regular bike into an electric bike for less than $450. The main attraction is the strong 1000W motor that helps you climb hills and go fast without breaking a sweat. You get everything needed to do the conversion - the motor, a battery that clips onto your bike frame, a screen to show your speed, and all the tools to put it together. The battery is big enough to last for many rides before you need to charge it up again. One thing to watch out for is that the product listing is confusing. The title says it's a 48V 1000W motor, but the description talks about a 36V 250W version. This makes it hard to know exactly what you're getting. If you're handy with bike repairs and want to save money compared to buying a complete electric bike, this kit could work great. You can use your existing bike that you already like and just add the electric parts. The nine different power levels mean you can choose how much the motor helps you - use low power to get a little exercise, or crank it up when you're tired or going uphill. This kit works best for people who already have a good quality regular bike and want to make it electric. It's perfect if you like DIY projects and don't mind spending a few hours installing parts. However, if you're not comfortable working on bikes or don't have the right tools, you might need to pay a bike shop to install it for you. Also remember that this is just the motor and battery - you don't get lights, a rack for carrying stuff, or any suspension. Your riding experience depends a lot on what bike you attach it to. If you want a ready-to-ride electric bike with everything included, you should look at complete e-bikes instead of conversion kits.

What We Like

  • Powerful 1000W motor with 80NM torque handles steep hills and heavy loads easily
  • At $439.99, you get excellent value with motor, battery, display, and all installation tools included
  • Nine levels of pedal assist plus throttle give you lots of control over how much help you want

What Could Be Better

  • You have to install it yourself on your own bike, which can be tricky if you're not handy with tools
  • No lights, fenders, or suspension included - you only get the motor and battery parts
  • There's a mismatch in the listing - title says 48V 1000W but description mentions 36V 250W specs
  • Not certified by UL or other safety organizations, which some buyers may worry about
  • Only 34 customer reviews means it's less proven than popular complete e-bikes with thousands of reviews

Frequently Asked Questions

Common questions about Bafang Electric Bike Conversion Kit Mid Motor BBS-HD 48 V 1000 W Motor Accessories Display Optional Kit Downtube Battery

Will this kit fit my bike?

It works on bikes with bottom brackets that are 34-36mm wide and 68-73mm across. It fits bikes with chain drives and either V-brakes or disc brakes, but not bikes with belt drives or backpedal brakes.

Do I get a battery with this kit?

Yes, the package includes a 36V 13Ah battery that mounts on your bike frame, plus a charger. The battery can be recharged 800-1000 times before it wears out.

Is this hard to install if I've never worked on bikes before?

The kit includes all the tools you need, but installing a mid-drive motor requires removing your bike's pedals and bottom bracket, which can be challenging if you're not experienced with bike repairs.

What's the difference between the 1000W and 250W mentioned in the listing?

The listing is confusing - the title says 1000W but the description mentions a 250W version. You should contact the seller before buying to confirm which motor you'll actually receive.

How far can I ride on one battery charge?

The listing doesn't specify the exact range, but with a 468Wh battery (36V x 13Ah), you can expect roughly 20-40 miles depending on how much you use the motor and how hilly your route is.
