The Heybike Mars offers almost everything you could expect from a folding bike at an amazingly low price.

The bike offers the convenience of a foldable design, allowing for effortless storage and transportation. With its ability to fold in half, it becomes compact enough to fit into my car trunk without requiring me to fold down the car’s back seats. Even when brought indoors, it occupies minimal space. However, it’s worth noting that the bike does have a substantial weight of 66 lbs, which presented some challenges when carrying it up or down my narrow stairs. Additionally, due to its larger and heavier components, the folding and unfolding process is not as swift as with lighter models.

Equipped with a robust 500W geared hub motor, the Heybike Mars showcases a maximum speed of 20mph, which can be further amplified by pedaling thanks to its 7-speed Shimano drivetrain. Its range varies between 20 to 46 miles, contingent on the chosen level of pedal assistance. The bike offers three levels of pedal assistance alongside a full throttle mode. By utilizing the convenient thumb throttle on the right handle, you can effortlessly ride without pedaling, although this significantly reduces the battery range to approximately 20 miles. It’s worth noting that pedaling the Heybike Mars can be more strenuous compared to a regular bicycle, so it’s advisable to consider shorter distances when relying solely on manual pedaling.

One of the commendable features of the Mars is its removable battery, which can be effortlessly locked or unlocked using the provided key. This allows you the convenience of recharging the battery anywhere or simply leaving it secured on the bike. Moreover, the battery incorporates a useful USB port, enabling you to utilize its power to recharge your electronic devices on the go.

While the Heybike Mars stands out in numerous aspects, it does have its imperfections. Personally, I find the pedal assistance system to be somewhat flawed, as it provides a significant power boost even at very low speeds. Even when setting the pedal assistance at level 1, I was surprised by the sudden surge in speed. However, this is a common trait among budget e-bikes available in the market, as they typically employ cadence sensors.



  • Affordable price
  • Compact design
  • Extremely comfortable on all terrains
  • Good battery range


  • Heavy
  • Difficult to control pedal assistance at low speed

Heybike Mars is one of the most cost-effective fat e-bikes available in the market. While it may be slightly heavy, its exceptional comfort and impressive folding capabilities have no complaints. As a result, Uivercellapps wholeheartedly recommends the Heybike Mars for all e-bike enthusiasts.
