The TWIKE Active is basically the original electric /
pedal-assisted version that Ralf Schnyder and his colleagues of the TWIKE
AG started producing for the Swiss market in 1996. Of course there have
been lots of improvements since then but the general design never needed
a major change. The idea has proven it's practicability over millions
of miles!
The TWIKE Active is a light-weight electric vehicle which is also equipped
with two sets of pedals that can be operated individually by the driver
and the passenger.
The pedal drive acts directly on the rear wheels with only a 5 speed gear box and a long chain in between. This system guarantees an efficient use of the human power input and makes the TWIKE Active a real hybrid vehicle.
