Hi there, thank you for reaching out. The rain cover features zippers that allow you to open it for ventilation. It can also be fully removed if desired, turning the cargo area into an open space.
The E-325 features hydraulic disc brakes with 180mm rotors (rotors on all 3 wheels) for reliable stopping power. It also includes a parking brake system that can lock the wheels when stopped.
It comes with a 48V 20Ah Samsung lithium-ion battery. Under light assist (PAS 1), you can get 60+ miles per charge—actual range can vary with riding conditions.
