FAQs

To unlock the top speed of your Fastron SO, which is set to a default of 20 MPH, follow these steps: Navigate to the settings page on the display -> Enter the advanced settings -> Input the password (please email us to obtain the password) -> Change the C3 option from 'off' to 'on' -> Save the settings and exit. This will activate the capability to reach up to 28 MPH.
Fat tires significantly improve traction and stability on a variety of terrains, offering a smoother, more comfortable ride. Their wide surface area enhances grip in both wet and dry conditions, reducing the impact of bumps and ensuring a safer, more controlled cycling experience across all terrain types.
The Fastron SO, a step-over bike, features a high top tube for unmatched stability and power, providing better control and efficiency for those who love speed and adventure. It's perfect for off-road riding, making it ideal for active riders!
The only difference between the Fastron ST and Fastron SO is the design of the top tube. Your choice depends on personal needs and cycling habits. If you're looking for easy mounting/dismounting and a comfortable ride, the Fastron ST's step-thru design is for you. But if you crave speed, intense riding experiences, or need extra stability for challenging conditions, the Fastron SO's step-over design is the better option.
The recommended rider height is 5'3" ~ 6'4", payload 350lbs at maximum.
To charge your Fastron SO's battery, you have two options: Directly connect the charger to the charging port on the bike's frame, or use the key to unlock the battery package, remove the battery, and charge it separately. A full charge typically takes only 4-5 hours.

I reached out to a few brands before buying, but LEOGUARs customer service was the best by far. They explained everything in detail, and its clear the quality matches the price.

After checking out tons of fat tire ebikes, I kept coming back to LEOGUAR. The attention to detail and build quality are unmatched. Im so glad I went with this one.

A Christmas gift for my wife. I originally thought it would arrive before Christmas, but unfortunately, I only received it today. It is probably due to the heavy pressure on delivery during the holiday season, which I can understand, but I am still a bit disappointed.

Just got this bike, and as a cycling enthusiast, I am impressed. I checked out the motor, battery, and frame everything is topnotch. Can not wait to hit the trails with it!

The display is full color and even has a startup animation, which is a nice touch. Plus, it is waterproof, so no worries about riding in the rain.
