Development of the FLYER® e-bikes
The origin: Red Buffalo (1993)
Philippe Kohlbrenner constructed this first FLYER himself. He lived on the Lueg hill in the Emmental region and worked for a power engineering company at the bottom of the valley. Legend has it that his wife was such a good cook that he always wanted to ride home for lunch up the hill. However, at some point, the 300-metre difference in altitude got too much for him, which is why he had the idea of motorising his bicycle. To achieve this, he fitted a lorry windscreen wiper motor and a car battery. He used an ampere meter to control motor performance, while a simple flip switch on the handlebars served to start the “Red Buffalo", whose name originated from the red-painted frame of this first FLYER e-bike and the aerodynamic handlebar position.
The FLYER originated from a need to get around and was developed in several stages. After the first prototype of an electrified bicycle, “Red Buffalo” (“Roter Büffel”), hit the road in 1993, the company BKTech AG produced a small series of a first serial product from 1995 to 1999: the FLYER Classic.

FLYER R Series, 2011 - 2013 model years
The R Series was consistently pared down to focus on sportiness, and the seating position was even sportier than that of the S Series. Winner of the Eurobike Award, the R Series was available in black and white with a performance of up to 350 W. The speed sensor meant that the pedal frequency range was even wider on the Deluxe models.
FLYER Vollblut, 2013 - 2014 model years
At its time, the Vollblut was the “power FLYER” with a 250 W or 500 W motor. The hub motor was available with 28” wheels, or as a Special Edition with 27.5” wheels, as well as with the option of pedal assist up to 45 km/h or 25 km/h. A wide range of components and features were available, depending on the area of application.

This series was developed for those who were unwilling to compromise and wanted a fast, resilient e-bike with a long distance range that is reliable for everyday use.
FLYER B Series, 2014 - 2017 model years
The high level of stability of the FLYER B Series, combined with the low step-through frame, provided a unique sensation of riding safety. The aesthetically pleasing integration of the battery into the luggage rack meant it was almost invisible. The FLYER B Series is ideal for riding both through the countryside and around town.
FLYER Goroc, 2015 - 2016 model years
The Goroc was available in the colours black or white, and with 250 or 350 watts. Smooth welding seams on the frame, disc brakes, and Shimano SLX or XT gear components were testament to the quality of this lightweight athlete. The 100 mm or 120 mm suspension made uneven surfaces a thing of the past.

The FLYER TS Series was the elegant and stylish companion for urban commuters. At the time, the e-bike was designed for people who wanted their journey from A to B to be dynamic and stylish. The graceful yet sophisticated design offered a unique modern lifestyle.

With the FLYER C series, Biketec AG, which emerged from BKTech, built Europe's first electric bicycle with lithium-ion technology in 2003. This massively reduced the weight and massively increased the range. The low step-through frame, solid and reliable technology, as well as user-friendliness were testament to the high level of customer focus. Until the end of 2018, the C-Series made it possible for a broad public, including older people in particular, to ride bicycles. Its successor is the Gotour4.
FLYER T Series, 2006 - 2019 model years
The T-Series combines a long range and safe and stable handling with an ergonomically extremely comfortable seating position. The classic, high-quality frame was impressive with its timeless elegance and 28-inch wheels. Its successor is the Gotour5.
FLYER Uproc6, 2015 - 2019 model years
A lot of time was invested in optimising frame stiffness and chassis performance in the enduro with 160 mm suspension travel.
