How this e-bike scores for different riding styles
The foldable frame design combined with fat tires makes this highly portable for apartment storage and multi-modal transportation. The removable battery adds to convenience for indoor charging in small spaces.
With 80-mile max range and 30+ MPH speed, this bike excels for commuting. The foldable design makes it easy to store at work or take on public transit, and the removable battery allows indoor charging.
Excellent for beach and casual riding with fat tires and comfortable suspension. The 80-mile range allows all-day recreational rides without range anxiety, and pedal assist offers flexible effort levels.
The 1000W motor (1500W peak) and 30+ MPH top speed deliver strong performance for enthusiasts. However, the carbon steel frame and 20-inch wheels limit ultimate performance compared to dedicated high-performance models.
The 20-inch fat tires, 1000W motor, front suspension, and disc brakes provide solid off-road capability. However, only front suspension limits performance on extremely rough terrain compared to full-suspension models.
No rear rack, limited cargo features, and unknown weight capacity make this poorly suited for heavy hauling. The bike is designed more for rider mobility than utility transportation.
Our Verdict
The Cybervelo EK4 folding electric bike gives you a lot of bike for not much money. At $649, you get a really strong 1000W motor that zooms up to 30+ MPH and a giant battery that lasts 80 miles. That's enough to ride all week without charging if you have a short trip to work. The bike folds up which is perfect if you live in a small apartment or want to take it on the train. The fat tires are chunky and wide so you can ride on beaches, through snow, or on dirt trails without worrying. The LCD screen shows you how fast you're going and how much battery is left.
This bike is best for people who need to get to work every day and want to save money on gas or bus tickets. It's also great if you live in a city apartment and need a bike that folds small. The long range means you won't get stuck with a dead battery far from home. Weekend riders will love taking this to the beach or on bike trails because the fat tires handle sand and bumps really well. The fold-up design means you can throw it in your car and drive to fun places to ride. People who weigh more will appreciate the sturdy carbon steel frame.
This bike isn't the best choice if you want the lightest bike possible - the steel frame makes it heavier than aluminum bikes. If you need to carry lots of groceries or heavy stuff, look for a bike with a cargo rack because this one doesn't have one. Serious mountain bikers might want a bike with front and back suspension for really rough trails. You'll need to buy lights separately if you ride when it's dark outside. Some people want UL certified bikes for extra safety testing, and this one doesn't have that stamp. But if you want tons of power and range without spending $1,500 or more, this bike gives you amazing value.
What We Like
- Huge 48V 20.8AH battery gives you 80 miles of riding on one charge, which is way more than most bikes in this price range
- Super powerful 1000W motor (1500W peak) gets you up to 30+ MPH and makes hills feel easy
- Folds up so you can store it in small apartments, take it on the bus, or fit it in your car trunk
- Fat tires work great on sand, snow, and rough roads so you can ride almost anywhere
- Only $649 for all these features is an amazing deal - similar bikes cost twice as much
What Could Be Better
- No built-in lights means you need to buy and attach your own if you ride at night
- Not UL certified which some buyers want for safety peace of mind
- Carbon steel frame is heavier and less fancy than aluminum frames on pricier bikes
- Only front suspension so bumpy trails will still feel rough on your backside
- No throttle mode listed so you might need to pedal all the time instead of just twisting a grip to go
