RunOn is an electric kick scooter that helps passengers move short distances (up to 5 km) in an urban city center.
The main design goals were portability, aesthetics and usability. RunOn has maximum speed 25 km/h and battery strength 10 km route consisting of one deck, two front wheels and one rear wheel, a lean-to-steer mechanism, a steering and an electric system (rechargeable battery, motor, controller). The main target group consists of men and women aged 25-45 years old with a stable income who tend to lean towards high quality or luxury objects. Due to the target audience's preferences, RunOn uses simple forms and geometry.

RunOn is an electric kick scooter that meets a user’s (payload
100 kg) short distance (up to 5 km) traveling needs. The main design goals were portability, aesthetics and usability.
The product has a maximum power of 750 W, a maximum speed of 25 km/h and a
battery life of 10-15 km.
deck houses the lean-to-steer steering mechanism as well as the rechargeable
battery, the small motor and its controller. Two wheels at the front and one at
the back guarantee stability and ease of use, while a small light
reflector at the back offers additional safety.
target group consists of men and women aged 25 to 45 with a stable, medium to
high income, interested in new trends and high-tech products combining
flexibility and functionality with high aesthetics.
can be used on the way to work, reducing commuting time; it can easily be
carried inside a commuter bus or train. Users can enjoy it while visiting
friends, going shopping or just strolling around.
the target group’s usual preferences, RunOn is characterized by simple forms
and geometry and comes in two versions, one with carbon fiber as the main
material and one with wooden deck.
preliminary investigation focused on the basic design specifications and
design priorities. The research tools used were:
Group Analysis •
Questionnaire • Personas • User
Scenarios • Market
“Detailed product design” class, we worked on a detailed 3d model and even
construct a prototype. The hands-on process was overall very beneficial with
many lessons learned. The result was an almost functional prototype made of
metal parts and wood (beech, oak).
concept is distinguished by its unique, safer and more comfortable way of
driving due to the presence of two wheels on the front of the vehicle. A dominant
feature of the concept is the way the vehicle turns, which allowed us to design
an innovative steering system.
The way the
vehicle is driven is simple, with the user operating the throttle and the brake
on the steering wheel and turning by tilting the body in the corresponding
handlebar includes an anti-slip grip at the top, a thumb throttle at the right,
a hand brake at the left and a screen showing the main system information,
battery status and speed.
most important element of the scooter is the lean-to-steer mechanism. It
consists of conical gears that convert the movement of the deck (made on the x
axis) into wheel turning (on the y axis). This is done with the help of the
bearings that support the movement and the conical bearings, achieving smooth
operation without interruptions. The shaft (steering) which is connected to the
top gear, moves and turns the wheels right and left, being attached with the
deck via a netting.
ready to be carried with two simple moves: Minimising the height of the
handlebar and bringing it down to snap close to the rear wheel. The anti-slip
grip of the handlebar “hugs” the rear wheel and the whole object is carried
away by dragging it, like a cabin luggage.
Underneath the deck's surface can be found the lean-to-steer mechanism, the space for the batteries and the system controller, and the rear wheel, where the motor is located, with its disc brake.
deck’s back end, a wing prevents the foot from touching the wheel and a light
reflector improves the visibility of the scooter at nighttime.
basic material is carbon fiber, which provides high rigidity, high strength and
low coefficient of thermal expansion. These characteristics, combined with low
weight and chemical resistance, make carbon fiber a very popular material in
vehicle construction as in our case.
of the target audience’s aesthetic approach drove us to design three versions
for the RunOn: The fully black version with black carbon as basic material, the
white version with painted white carbon and a third version with the deck being
made of wood (oak, beech).
