The surf board uses waves to gain power and speed - the stairboard uses stairs. Royal College of Art graduate PoChih Lai has designed the Stair Rover, mainly of bamboo, maple, aluminium, PU rubber, which basically lets you roll down those stairs which you just recently feared.
PoChih was inspired by London as a city when creating the board:
"This advanced boarding activity turns boundaries and restrictions into a positive and creative physical enquiry into the ever changing kinesis of the urban ecosystem."
“My idea is basically the same as surfers,” Lai tells Co.Design. “They look for the hidden energy of nature, which is waves. Mine is looking for the hidden energy around us. Interestingly what I found is stairs, there are plenty of stairs hidden around our playground and habitat—the city.”
