How this e-bike scores for different riding styles
The 8000W motor with 150A controller delivers exceptional power far exceeding typical e-bikes. This kit is designed for maximum performance and speed capabilities for enthusiasts.
The 8000W motor provides exceptional power for trails and rough terrain. The hydraulic disc brakes and terrain tire make it capable for aggressive off-road use.
The powerful 8000W motor could handle heavy loads, but without specifications on weight capacity or cargo features, and being just a conversion kit, its utility application is limited.
The extreme 8000W power is overkill for casual riding, and the lack of a complete bike package makes it unsuitable for leisurely recreational use without significant DIY work.
This is a conversion kit, not a complete bike, making it impractical for regular commuting. It lacks integrated lights and a battery, which are essential for safe daily urban travel.
This is a motorwheel conversion kit that isn't foldable or portable. It's designed for installation on an existing bike frame, not for easy transport or storage.
Our Verdict
The NB POWER QS 273 8000W motorwheel kit is a super strong motor that you can add to your own bike. With 8000 watts of power, this motor is much stronger than regular e-bikes which usually have 500 to 750 watts. Think of it like putting a race car engine in a regular bike. This makes it great for people who want to go really fast or climb really steep hills. The kit comes with good brakes that use liquid to help stop you, and it has a screen that shows you how fast you're going.
This kit is perfect for people who already have a bike and want to make it go much faster. It's great for people who like to ride on dirt trails or mountain paths where you need lots of power. People who love working on bikes and building their own custom rides will really enjoy this kit. At $379, you're getting a really powerful motor for less money than buying a whole new e-bike. The throttle lets you control the speed with your hand, and the big brake discs help you stop safely even when going fast.
However, there are some big problems to think about. This is just the motor and some parts - you don't get a battery, so you have to buy that separately which costs more money. Without a battery, we can't tell you how far you can ride before it runs out of power. There are no lights included, so riding at night could be dangerous. The kit hasn't been tested by official safety groups, so you need to be extra careful when you put it together. Also, with only 4 reviews and a rating of 3.3 stars, not many people have bought this yet and some who did had problems. If you want a complete bike that's ready to ride right away, or if you've never built a bike before, you should look for a different option that comes with everything you need.
What We Like
- Super powerful 8000W motor that's way stronger than most e-bikes - great for steep hills and fast speeds
- Really good hydraulic disc brakes with big 203mm rotors that can stop you quickly and safely even at high speeds
- Comes with a strong 150A controller that can handle all that motor power without breaking
- Great price at $379 for an 8000W motor kit - most kits this powerful cost way more money
- Has a throttle and LCD display so you can control speed easily and see important information while riding
What Could Be Better
- This is just parts to add to a bike you already have - it doesn't come with a battery, frame, or wheels so you need to buy those separately
- No battery included means you can't tell how far you can ride on one charge
- Missing safety features like lights which makes it hard to ride at night or when it's dark outside
- Not certified by UL so there's no official safety testing to make sure everything is safe
- Only has 4 reviews with a low 3.3 star rating which means not many people have bought it and those who did weren't super happy

Frequently Asked Questions
Common questions about NB POWER 150mm Dropout QS 273 8000W motorwheel Ebike kit with 150A V2 Sabovoton Controller,Hydraulic Brake with 203 disc Brake,8000W Ebike Motor kit
Does this come with a battery so I can ride it?
No, this is just a motor kit. You need to buy your own battery separately to make it work. The kit only includes the motor wheel, controller, brakes, and display.
How fast can this 8000W motor go?
The product details don't say exactly how fast it goes, but with 8000 watts of power, it can likely go much faster than regular e-bikes which usually top out around 20-28 mph. It's built for high speed.
Can I put this motor on any bike I already have?
You need a bike with a 150mm dropout spacing to fit this motor wheel. The kit comes with a 21 inch front wheel, so you'd be replacing your front wheel with this motorized one.
Is this legal to ride on public roads and bike paths?
Most places have laws that limit e-bikes to 750 watts or less for public roads. At 8000 watts, this motor is way over that limit, so it's probably only legal on private property in most areas.
What comes in the box when I buy this kit?
You get the 21 inch motorwheel with an 8000W motor, a 150A controller, hydraulic disc brakes with a 203mm brake disc, an LCD display, and a throttle. No battery or bike frame is included.
