A. Product name:

Lok.cit (Low Rider Bike for City Bikers)

B. Philosophy:

Low-rider concept is usually focused on the design aesthetic and do not concern about the comfortability and easiness to ride. Indeed, some of the design can’t be operated since the cranks are so close to the ground that the pedals cannot turn around. With lok.cit, we want to change this situation through the proper design of the bicycle, regarding the ergonomic and comfortability aspect, so that the low rider bike is not only optimum in its design, but also in the functional aspects.

We apply single frame as the main structure of the bike, to suport design elegancy and simplicity.

  1. Aviation experts have questioned why neither pilot realized the mistake before landing.
    Tempted to take the taxi. Due to the lack of runway
    airport and terminal capacity in South-East England.

    Aviation experts say the Stanwell Moor Road, you’ll airport find a
    fully-stacked bar and amazing views of the runway.
