How this e-bike scores for different riding styles

Off-Road Adventure
92/100

Exceptional off-road capabilities with 26x4" fat tires, 1600W motor with 2000W peak power, front suspension, dual hydraulic disc brakes, and 440 lbs weight capacity. The 21-speed Shimano drivetrain and aluminum frame provide excellent trail performance.

High Performance
88/100

Outstanding performance with 1600W motor (2000W peak), 28 mph top speed, and strong climbing ability via 21-speed drivetrain. The powerful battery (48V 20Ah) and dual hydraulic brakes support aggressive riding, though not the absolute fastest in class.

Recreational Leisure
85/100

Perfect for casual riding with cruise control, comfortable suspension, multiple riding modes, and fat tires for beach/snow riding. The 40-mile range supports all-day recreational adventures without range anxiety.

Daily Commuting
78/100

The 40-mile range and 28 mph top speed make this suitable for most commutes, with removable battery for convenient charging. However, the heavy fat tire design and lack of rear rack reduce practicality for daily urban use.

Cargo & Utility
68/100

The 440 lbs max load capacity is excellent for hauling, and the powerful motor handles heavy loads well. However, it lacks a rear rack and cargo-specific features, limiting practical utility applications.

Compact & Portable
15/100

This is a non-foldable fat tire bike weighing significantly more than compact models. The 26" fat tires and full-size frame make it unsuitable for apartment storage or public transit integration.

Our Verdict

The QIKAITU K800 is a powerful fat tire electric bike that gives you a lot of performance for $799. With a strong 1600W motor that can reach 2000W at peak power, this bike goes up to 28 miles per hour and climbs hills with ease. The huge 48V 20Ah battery gives you 40 miles of riding on one charge, which is really good for the price. The bike has big 4-inch wide tires that work great on sand, snow, dirt trails, and city streets. You also get hydraulic disc brakes that stop you safely, a front suspension to smooth out bumps, and 21 gears to help you tackle different terrain. It's UL certified, which means it passed safety tests, and can hold riders up to 440 pounds.

This bike is perfect if you love outdoor adventures and want to explore trails, beaches, or snowy paths. The fat tires and powerful motor make it great for off-road riding and tackling tough terrain. It's also good for people who want a fun recreational bike for weekend rides or cruising around the neighborhood. The cruise control and multiple riding modes make it easy and enjoyable to use. If you're a heavier rider or want to carry lots of gear, the 440-pound weight limit gives you plenty of capacity. For the price of $799, you're getting features that usually cost $1,200 or more on other brands.

However, this bike isn't the best choice if you need something portable or live in a small apartment, because it doesn't fold and the fat tires make it bulky. Daily commuters might find better options with rear racks and lighter designs for easier parking and carrying stuff. The battery takes 6-8 hours to charge, so you need to plan ahead. Since this model has zero reviews so far, we can't say how reliable it will be long-term. If you want the latest tech features like USB charging or smartphone apps, you'll need to look at pricier models. But if you want a powerful, capable electric bike for adventure riding at a great price, the K800 delivers strong value.

What We Like

  • Super powerful 1600W motor with 2000W peak power gives you strong acceleration and can handle steep hills easily
  • Big 48V 20Ah battery (960Wh) means you can ride 40 miles on one charge, which beats most bikes in this price range
  • Wide 26x4 inch fat tires let you ride on sand, snow, mud, and rough trails that normal bikes can't handle
  • Can carry up to 440 pounds, so you can bring a passenger or load up with gear without worrying
  • UL certified for safety and comes with dual hydraulic disc brakes that stop quickly even in wet weather

What Could Be Better

  • Takes 6-8 hours to fully charge the battery, which is longer than some newer fast-charging models
  • No rear rack included, so you need to buy one separately if you want to carry bags or groceries
  • Can't fold up, making it hard to store in small apartments or take on buses and trains
  • Brand new with no customer reviews yet, so we don't know how it holds up over time
  • Missing USB charging port and app connectivity that some other bikes at this price now include
