How this e-bike scores for different riding styles
Exceptional off-road capability with 1000W motor, 4-inch fat tires, dual crown suspension, and 35-degree hill climbing ability make this ideal for trails and rugged terrain.
Peak 2000W power, 28 MPH top speed, 85NM torque, and aggressive hill-climbing capabilities deliver strong performance for enthusiasts seeking power and speed.
Fat tires, comfortable suspension, and 5 assist levels provide excellent versatility for beach, snow, and casual neighborhood rides with smooth handling.
The 50+ mile range and 28 MPH speed work well for commuting, but the 101-pound weight and lack of integrated lights reduce practicality for daily urban use.
The 330-pound max load capacity is decent for utility use, but the lack of rear rack and the bike's own 101-pound weight limit practical cargo hauling.
Not foldable and weighing 101 pounds makes this one of the least portable e-bikes, unsuitable for apartment storage or public transit use.
Our Verdict
The TerraSpoke K800 is a powerful fat tire electric bike that gives you a lot of bang for your buck at $699. With a strong 1000W motor that can peak at 2000W, this bike has enough power to climb really steep hills and zoom up to 28 miles per hour. The big 48V 15AH battery is impressive too, giving you more than 50 miles when you use pedal assist mode, or about 30 miles if you just use the throttle without pedaling. The bike has passed UL safety tests, which means it meets important safety rules, and it can carry riders up to 330 pounds. The colorful LCD screen is easy to read and shows you all your ride information.
This bike is perfect for people who love outdoor adventures and want to ride on trails, beaches, or snowy paths. The super wide 4-inch fat tires and dual suspension work together to make rough terrain feel smooth and comfortable. If you like exploring different types of ground - whether it's dirt roads, gravel paths, or even sand - this bike handles it all really well. It's also a solid choice for casual weekend rides around your neighborhood or trips to the park. The 21 speeds and 5 levels of pedal assist let you pick exactly how much help you want from the motor.
However, this bike has some downsides you should know about. At 101 pounds, it's one of the heaviest e-bikes around, which makes it tough to carry up stairs or lift onto a bike rack. It doesn't fold, so you need plenty of storage space in your garage or home. There are no lights built into the bike, so you'll need to buy separate lights if you plan to ride when it's dark. The brakes are mechanical disc brakes instead of hydraulic ones, which means they work okay but aren't as smooth or powerful as what you'd find on pricier bikes. If you need a light bike for taking on the bus, or want something easy to store in a small apartment, you should look at folding models instead.
What We Like
- Super strong 1000W motor with 2000W peak power gives you plenty of juice to climb steep hills up to 35 degrees
- Big 48V 15AH battery gets you more than 50 miles when using pedal assist, which is great for long rides
- Fat 4-inch tires and dual suspension make bumpy trails feel smooth, perfect for snow, sand, and rocky paths
- Amazing price at $699 for a 1000W bike with these features - most similar bikes cost $400-$600 more
- UL certified for safety and can carry up to 330 pounds, making it safe and strong for most riders
What Could Be Better
- Really heavy at 101 pounds, which makes it hard to lift, store, or load onto a car rack
- No built-in lights means you need to buy and attach your own if you ride at night
- Takes 5-8 hours to fully charge the battery, which is slower than many newer models
- Mechanical disc brakes aren't as powerful or smooth as hydraulic brakes that cost a bit more
- Can't fold up, so you need a big space to store it and can't take it on buses or trains easily
