Addmotor Grandtan M-340

Buyer highlights

• Three-wheel drivetrain. A rear differential lets the rear wheels rotate at different speeds through a turn; riders still need to slow down and keep their weight centered.
• Cargo setup. Front and rear baskets are included for groceries, gear or errands within the published load limits.
• Battery and range. The current page lists a removable 48V 20Ah Samsung battery and up to 85 miles in its most favorable assist test.
• Fat-tire traction. Four-inch tires can add comfort and grip on uneven paths, while also increasing steering effort and overall bulk.
• Braking and parking. Hydraulic disc brakes and a parking function help manage stops and loading on appropriate surfaces.
• Electrical certification. The current product page identifies the electrical system and battery as UL 2849 and UL 2271 certified.
