    EKX X21

    I have this EKX 21 bike and ride it in the desert mostly. I've put a hard 165 miles on it and have no complaints so far. The EKX stops well and trails in the sand good the rest is pretty much easy as far as terrain. The bike last long and dose 30 mph the whole time. I never pedal. I just move my feet when I go around corners. I'm 168 lbs. and I haven't ever bottom out on the jumps. You can sit or stand in dirt. It pretty much drives the same after you get taller bars. With the stock bars it gets a bit shifty in the sand standing up. Cheap amazon bars fixed that. It's not my fastest bike but it is one of my favorites to ride.

    The EKX X21 Adult eBike is designed for both off-road adventures and urban commuting. It features a powerful 2000W motor and a large-capacity 35Ah battery for extended range and high performance. With automotive-grade shock absorbers, hydraulic brakes, and robust snow fat tires, it ensures a smooth and safe ride on various terrains.
