YAMAHA - PIONEERING SPIRIT
YAMAHA - 50 years ago, the Japanese company's developers realised that cyclists could use support when riding uphill and into headwinds. The first experiments were a bicycle with a 25 cc petrol engine in 1973 and a mountain bike with a 35 cc engine in 1982. But YAMAHA was not satisfied with this, because they wanted to build a vehicle that people who did not ride motorbikes could also handle. In 1989, the "Power Assist System" (PAS) was finally introduced: a prototype for bikes with electric assistance. It was to take another five years before the YAMAHA PAS was ready for the market in April 1994 as the "world's first product" of this kind.
Since that day, YAMAHA has constantly developed its motors further and in 2013, the PW series began its triumphal march. In Japan alone, YAMAHA sold two million e-bikes and their drives are used in over four million e-bikes worldwide. YAMAHA motors are used ex-works in the following brands, among others: Haibike, Gitane, Bixs, Atala or Lapierre.
YAMAHA AND GIANT
The well-known e-bike manufacturer GIANT has equipped the YAMAHA PW-X drive with specially developed software and optimised it for use with e-mountain bikes. These drives go under the name "Giant SyncDrive" or also Giant 2015/2016, but they are essentially modified YAMAHA motors.
WHICH YAMAHA MOTORS ARE THERE AND WHICH ONE DO I HAVE?
The name of the manufacturer is usually on the housing of the drive. In the case of YAMAHA and GIANT, at least, the name cannot be overlooked. You should also be able to find the exact name of the motor in the data sheet that comes with the bike. The next generation of mid-range motors was launched by YAMAHA in 2014 with the PW series and has been continuously developed since then. Here is a compact overview of the motors from YAMAHA:
PW series: 250 W / 70 Nm / up to 25 km/h
