The bike is completely unusable and dangerous
I bought a brand new Fafrees FF20 CUV (30AH) cargo bilke to carry my two children to school. There is a big issue with the elecrical assitance on this brand new bike. The electric engine assistance helps when I start pedalling and then stops after a few seconds. I cannot ride uphill, it's exhausting. I have to use the breaks and almost stop the bike for the electric assistance to help again, and only for a few seconds. I am extremely disappointed. Dangerous Motor Behavior: When I pedal, the motor does not provide smooth assistance. Instead, it suddenly delivers violent and unpredictable bursts of acceleration. This erratic behavior occurs randomly and causes a sudden loss of control, which is extremely dangerous in traffic. Extreme Instability (Kickstand Defect): The dual kickstand provided is too narrow and fragile. When my children try to get onto the bike, it immediately tilts and falls over. The bike completely lacks the stability required for a cargo bike. Frame & Riding Instability: When riding, the frame suffers from severe flex/torsion under load, making the steering highly unpredictable and unsafe. The bike is completely unusable and dangerous.
