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.

This bike is amazing for the price, I purchased 3 of them and they have exceeded my expectations. I also worked with there warranty department on a replacement motor and they stand by there warranty. I highly recommend
5 star so far bike is great very easy to put together!
Great value for the bike. Solid materials and quality.
Really good ebike… brakes were kinda bad but over all it runs great.
wish you guys sell tires for the ebike
Rides great, max speed 35mph on a flat surface and going downhill just increases speed insane. I like!!
The suspension makes a lot of noise while riding not sure if because I’m heavy but I weigh 170. A little on the heavy side to pick up. Brakes are good, headlights and taillights works magnificent. Love how it got the turn signal feature. 4 stars because I wish there was accessories for the bike.
