In September 2015, in Nevada the Policumbert team of the Politecnico of Torino with the prototype Pulsar has established the new Italian speed record on a human propulsion vehicle, whizzing at a speed of 166.9 km/h.
A very similar concept was developed in 1935 by THAYAHT, with the project multiplies PLURILEVA, a 42-tooth elliptical crown capable of increasing the performance of the human thrust on the pedal and applicable to any bicycle

THAYAHT also applies it to its futuristic pedal-wheel design.
