Yamaha will release the "PAS Brace" Aug 8, 2008, in Japan. The new bike features an eight-speed internal hub gear and a shift position sensor to detect the gear speed at which it is running. A system called "S.P.E.C.8" decides an optimal assisting power at any time in the ride including the starting up, accelerating and running phases of the ride.
Electricity supply begins to decrease after the speed reaches 15km/h (9.32mph), and no electricity is provided at the speed of 24km/h or more. At the speed of less than 24km/h, the S.P.E.C.8 efficiently assists the pedaling by minutely controlling the electricity supply according to the gear in use.
The price of the bicycle (including a battery charger) is set at ¥125,800 (~ $1,168, including tax).
Specs:
Wheel size: 26"
Motor: DC brushless - 240 W
Battery: Lithium-ion 25.9V-4.0Ah
