How this e-bike scores for different riding styles
The 1000W motor delivers strong power output and the 28 mph (45 km/h) max speed offers thrilling performance. The dual-mode hall/non-hall controller ensures consistent power delivery, making this suitable for performance enthusiasts on a budget.
The 1000W motor and 4-inch fat tires provide excellent traction and power for trails and rough terrain. The 330 lb weight capacity and dual-mode controller ensure reliability, though being a conversion kit means overall durability depends on the base bicycle used.
The pedal assist system and LCD display make casual riding comfortable and engaging. The fat tires provide a smooth, stable ride for leisurely cruising, though the conversion kit nature requires technical setup that may deter casual users.
The 330 lb max weight capacity and 1000W motor provide adequate hauling power, but cargo utility ultimately depends on the base bicycle frame. The rear hub motor placement leaves the front wheel available for front baskets or cargo racks.
This is a conversion kit, not a complete bike, requiring DIY assembly and additional battery purchase. The 28 mph max speed is suitable for commuting, but the 20-inch fat tire setup is less efficient for urban roads and lacks integrated commuting features like lights.
The 20-inch wheel size offers some compactness compared to full-size bikes, but this is not a folding design and the fat tires add bulk. As a rear wheel kit, portability depends entirely on the donor bicycle frame chosen.
Our Verdict
This AW conversion kit is a budget way to turn a regular 20-inch bike into an electric bike without spending thousands of dollars. The 1000W motor is really powerful and can push you up to 28 miles per hour, which is faster than most street-legal e-bikes. The fat 4-inch tires are perfect for riding on beaches, snowy paths, or bumpy trails where regular bikes struggle. You get an LCD screen that shows your speed and battery life, plus pedal assist so you don't have to use the throttle all the time. The kit can handle riders up to 330 pounds, which is great news for bigger people or anyone who wants to carry groceries or camping gear.
This kit works best for people who already have a 20-inch fat tire bike and want to make it electric, or for DIY folks who enjoy building things and want to save money. It's perfect for weekend trail riders who want extra power to explore dirt paths and rough terrain. The dual-mode controller is smart because if something breaks, the motor keeps working so you can get home safely. At $280, this costs way less than buying a complete electric bike. But you need to remember that you still have to buy a 48V battery separately, which could cost another $200 to $400.
The big problem is that this kit doesn't include a battery, and the product description doesn't tell you how far you can ride or how long charging takes. You also need to know how to work with tools and wires to install everything yourself. If you mess up, you could break your bike or even hurt yourself. The kit only fits bikes with exactly 6 and 11/16 inches between the back wheel holders, so measure carefully before buying. There are no built-in lights for night riding, and it only has European CE certification instead of the stricter American UL safety rating. If you want a bike that's ready to ride right out of the box, or if you're not comfortable doing your own repairs, you should probably buy a complete e-bike instead of this conversion kit.
What We Like
- Super strong 1000W motor gives you lots of power to climb hills and go fast, reaching speeds up to 28 miles per hour
- Fat 4-inch tires work great on sand, snow, dirt trails, and bumpy roads where regular skinny tires would get stuck
- Can hold riders up to 330 pounds, which is more than most e-bikes and great for bigger people or carrying stuff
- Really cheap at just $280 compared to buying a whole new electric bike that costs $1000 or more
- Smart controller keeps working even if some parts break, so you won't get stuck far from home
What Could Be Better
- You have to buy the battery separately and build everything yourself, which takes time and tools most people don't have
- No information about how far you can ride on one charge, so you don't know if it'll last for your whole trip
- Only works with 20-inch bikes that have the exact right spacing between the back wheel holders, so it won't fit most bikes
- Doesn't come with lights or other safety features you need for riding at night or in traffic
- Only has CE certification from Europe, not the safer UL certification that American products usually have
