Le Halfbike est un véhicule de transport personnel ingénieux qui permet au cycliste de pédaler et manœuvrer dans une position verticale.
Designed by architect Martin Angelov, co-founder of Tuscon, Arizona-based transport design company Kolelinia Lab, the Halfbike has been characterized as a « low-tech Segway » which the rider controls and brakes through a single, central handlebar. Holding onto this central stick, user balances on the pedals, which drive the main front wheel forward through a chain, while the two smaller wheels at the back provide extra stability.
