The supplied 800Wh battery can be paired with an optional 480Wh secondary battery for 1280Wh in total. That gives you another option for longer rides without changing the bike you use every day.
Amflow quotes up to 172km (about 107 miles) from the standard battery, tested on flat tarmac in Eco mode with an 80kg rider. Treat this as a comparison figure: hills, luggage, assistance level and weather all affect how far you’ll ride. The supplied 168W charger takes approximately six hours for a full charge.
