As BYD's flagship three-row SUV, the Tang carries a taller stance that suits its size but adds a genuine reach for anyone getting into the second or third row. Decoin's electric running board closes that gap, extending the moment a door opens and folding away again once everyone's aboard.
Every door on the Tang triggers the same response: the running board slides out to offer a wide, stable step, then retracts fully once the door closes, keeping the SUV's flanks clean while driving.
Because the Tang seats up to seven, the running board is engineered to serve every row equally, so third-row passengers get the same easy step-in as those riding up front.
Finish options are chosen to suit the Tang's premium positioning, adding a coordinated look rather than an obvious aftermarket part.
Sealed against water and road salt, the mechanism is built to keep performing whether the Tang is on the school run or a longer road trip.
Can third-row passengers use the same step as the front doors? Yes, the running board extends the full length needed to serve all doors.
Does the added step reduce ground clearance off-road? No, the board retracts fully while driving, leaving clearance unchanged.
Is the kit specific to the Tang, or shared with other BYD SUVs? It's fitted specifically to the Tang's body dimensions and mounting points.
