FAQs
Please read our FAQs page to find out more
What is the warranty?
The original warranty for BG-X is 1 year.
Compared to 1000W, what is the advantage of BG-X with a 1500W motor?
The advantage of BG-X with a 1500W motor lies in its increased power, enhanced control, and improved riding experience. It has quicker speed and better overall performance, making it easy to navigate through traffic with agile maneuverability and conquer challenging terrain with reliable control.
What type of sensor is used on the BG-X?
Though BIGNIU e-bikes are designed to handle wet conditions, please keep in mind that riding in heavy rain may affect battery life and reduce traction, so exercise caution and avoid riding in the rain as much as possible. As for the waterproof level, the whole bike meets IPX5 standards; the motor, battery, and display meet IP65 standards.
What Types of Terrain Can BG-X Handle?
BG-X ebikes are designed for off-road use on rugged, unpaved surfaces with their wide and fat tires. These surfaces include dirt trails, gravel roads, grass, sand, and light snow. They can handle rougher terrains better than bikes with narrow road tires, but may still struggle on very technical mountain trails. BG-X is also suitable for all-season use.
Are BG-X E-Bikes Suitable for All Ages and Fitness Levels?
BIGNIU e-bikes are generally suitable for a wide range of ages (above 16 years old) and fitness levels, as the electric motor provides adjustable assistance to accommodate different riding abilities. Besides, please note the max load for BG-X is 330 lbs, and please consult with a healthcare professional if you have any health concerns before riding.
Does my height/weight suit the BG-X?
The recommended rider height for BG-X is 4'11" ~ 6'3"; The total payload capacity of Ranger S is 330 lbs (not including the bike weight).

Customer Reviews
Put over 100 miles on it in less than two weeks. Love this bike. Great purchase,
One week in and I'm over 100mile, It would have been more but the weather got in the way, or it might have been 200 miles.
Ive ridden for about 50 miles and I can say im loving my bgx pro and I can see many more miles to come. Few hang ups when I first got it out of the box and during the building process. But their support, Bigniu Tom and Karl Dean were really great helpers. Actually video called me and sent me helpful videos with things to help me fix my issues. Great customer service and care. My bike is fast and looks good and I get a lot of compliments and a lot of curious eyes. 10 out of 10 experience despite my early frustrations.
I'm very happy with my purchase ..I bought a lectric and it completely failed all the promises the add said . I've put about 300 miles on my new bigniu and couldn't be more satisfied..if I had one critique I'd say mirrors would have been a great add on
Purchased extended fenders and holes do not line up. What now?
