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).

About 7-8 Hours.
Any upgrades to the BGX yet?
We upgraded the shocks and brakes, the shocks were upgraded to be adjustable and the brakes have better braking.
I’m glad I held off so long before pulling the trigger on purchasing an e-bike! The BG-X rocks - sure it’s heavy, but it’s solid, and it looks very cool - a head turner!
You can still pedal it - one speed only, but you still get a workout on your legs as you’d like, yet it has speed and endurance for the fun of it or commute. Also, I love the idea of being able to sit in the saddle and have both feet flat on the ground.
Highly recommend.👍🏼👍🏼
Received my BG-X in 3 days, Packaging was done very good & thought out, Bike was fairly easy to put together. I have ridden the bike 20 miles as of now feels great, real sold looking forward to using it more !
I love it! I’m 5” 2 but can handle it fine. Battery last forever
First , i love it but there are 3 things not that goog for me .
1= handle bar too low and far .. i installed a extension
2 = seat not ajustable = i moved it back
3 = Rear gear too big or front gear to small = i put a 52 teeth gear on the front .
I've ridden motorcycles my whole life, I was involved in a horrific accident that made me have to sell my road king. When I was this i knew I had to have it, I absolutely love it!! Comfortable, plenty of power and speed, goes very far, the low center of gravity makes it handle very will! If you ever need a spokesman, im your guy!
