F4 Folding Electric Bike Review: Is This 500W Compact Commuter Worth It?

How this e-bike scores for different riding styles

Compact & Portable
95/100

Exceptional portability with quick-folding mechanism collapsing to just 17 inches height and 67.2 lb weight. Perfect for car trunks, public transit, and tight urban storage spaces.

Daily Commuting
88/100

With 35-mile range, 25 mph speed, and ultra-compact folding to 17 inches, this bike excels for daily commutes with easy storage in apartments or offices. The removable battery adds convenience for charging at work.

Recreational Leisure
70/100

The front suspension and adjustable seat provide decent comfort for casual rides, but 14-inch wheels limit smoothness. Better suited for short trips than all-day leisure cruising.

High Performance
55/100

The 500W motor with 50Nm torque and 25 mph speed offers moderate performance, but falls short of enthusiast-level specs. Better suited for practical transportation than thrilling high-speed rides.

Cargo & Utility
45/100

The 300 lb payload capacity is decent for groceries, but the small 14-inch frame and lack of rear rack limit cargo hauling practicality compared to dedicated utility e-bikes.

Off-Road Adventure
35/100

The 14-inch wheels and basic front suspension limit off-road capability despite the 500W motor. High carbon steel frame and small wheel size make this unsuitable for serious trail riding.

Our Verdict

This electric bike is a total game-changer if you're looking for something super cheap and easy to carry around. At just $159.99, it's probably the lowest-priced e-bike you'll find that's actually safe and certified. The best thing about it is how small it folds up - just 17 inches tall, so you can put it in your car trunk or tuck it under your desk at work. The battery slides out easily so you can take it inside to charge, which is really handy if you live in an apartment. It goes 35 miles on one charge and can hit 25 mph, which is fast enough for getting to work or running errands.

This bike is perfect for people who live in the city and need to save space. If you take the bus or train to work, you can fold this up and bring it with you. Students will love it because it's cheap and fits in a dorm room. Anyone who lives in a small apartment without bike storage will find this really useful. The price is so low that it's a great first e-bike to try out without spending a lot of money. It's also good for short trips around the neighborhood or combining with other types of transportation.

The biggest problem is those tiny 14-inch wheels. They make the ride feel bumpy and less smooth than bigger bikes. If you're tall or want to ride long distances for fun, this probably isn't the right bike for you. It's also not great for riding on trails or rough paths - the small wheels and basic suspension can't handle that. The motor is okay but not super powerful, so really steep hills might be tough. If you want lots of fancy features or need something that feels more like a regular bike, you should spend more money on a different model.

What We Like

  • Amazing price at just $159.99 with full UL 2849 certification, making it one of the cheapest certified e-bikes available
  • Super portable design that folds down to only 17 inches high, perfect for storing in small apartments or car trunks
  • The removable 48V 12Ah battery lets you charge it anywhere without moving the whole bike
  • Goes up to 35 miles on one charge with pedal assist, which is plenty for most daily trips around town
  • Has all the important safety stuff like dual disc brakes, bright LED lights front and back, and an easy-to-read display

What Could Be Better

  • Tiny 14-inch wheels make for a bumpy ride and feel less stable than regular-sized bike wheels
  • The 500W motor is only average power and might struggle on steep hills compared to stronger e-bikes
  • High carbon steel frame is heavier and less fancy than aluminum frames on more expensive bikes
  • Only has front suspension so you'll feel bumps in the back, especially on rough roads
  • Missing helpful features like throttle mode, USB charging port, and smartphone app connection
