The battery is also removable and compatible with other Rad Power models, adding flexibility for users who own multiple Rad bikes.

Rad Power has included thoughtful features on the RadMini 4, such as integrated front and rear lights powered by the main battery, enhancing visibility and safety during night rides. The rear light even has a unique flashing mode to signal braking. The bike includes mechanical disc brakes with large 180mm rotors on both wheels, which provide reliable stopping power, though some users might wish for hydraulic brakes for an even smoother feel.

Its frame is reinforced for durability, with telescoping handlebars and an adjustable seat post, making it easy to find a comfortable riding position. The RadMini comes with aluminum alloy pedals, a robust derailleur guard, and fenders to protect riders from splashes on wet days.
