What methods are suitable for the concept test?

Based on the target audience of our product, we have the following options for  concept testing methods

  •   Interview — interview people on the street using cameras and microphones
  •   Online – survey
  •   Physical  product testing
  •   Use 360 video camera to record the use of our product

We will interview around 10 people in Enschede center which suit our target group. They need to be traveling by bike and be between 18 and 25 years old.

What prototype is suitable for the concept test?

3D printed model

For the prototype testing we need to have a physical product, this makes it easier to show the concept to the target group and find potential problems. Using this methods we found problems with our first prototype and came with a new design.

App prototype

To show the functionality of our product we made an app prototype that responds to the LightBlue bean signal. The app controls the music player and is designed in an easy to use, simplistic way that fits with the style of our product.

To demonstrate possible uses and to attract the target group we used the basic prototype as a basis to design a new, aesthetically pleasing design. This illustration will be used to promote the product and make the usage clear.

What test persons will be selected for the test?

  • youngsters aged between 18 -25
  • Bikers on the street
  • People who are wearing earphones on the street


What conclusions will you draw from the test?

Things that people like
  • Design. :  It’s small and portable, can be carried around easily.  //
  • functionalities : It’s easy to understand what to do with the product .//
Things that people dislike
  • Design. :    The edges are too shape , maybe it can cut my hands when i use it . //.   the surface of the product can be a little more smooth.


functionalities :  Not enough functions for the price of the product .


What are the consequences of the conclusions of the concept?

This product has potential because a lot of people had mostly positive feedback from the interview and survey. However, for the product to be successful in the market we need to change certain aspects, like the shape, corners and add extra functionality to make it fit with the price.


3D printing and redesign

This week we got to print our prototype at the Fablab.

Before the actual printing could happen, we visited the Fablab to discuss the options with the students there. We needed to have flexible material in order to make the clicking mechanism more efficient.

There were 2 options

  • PLA filament
  • ABS filament

The prototype was printed in PLA filament, this material is less strong, but a bit more flexible. As our product is not very large and pretty solid, the strength would be good enough.


The product fits with the attachment clip as planned.


We did find problems with this prototype however.


The design is too clunky to be practical for a bike, the material is heavier than we thought and it would be in the way of the biker’s hand. Also we found that the 3D printer didn’t completely print the object.

New design

After we found that the prototype would not work, we had a new brainstorm session in the group to come up with a new, more practical design.

  • It needed to be much smaller and lighter
  • Buttons should be on top
  • No cornered shape


The new design is a lot smaller and can still fit the LightBlue bean inside. It is attachable in a similar way to the previous design and consists of two parts. The lid is removable to be able to change the batteries.

The next revenue stream will come from kick starter backers who were waiting to buy our product.

Afterwards our revenue will come from buyers on social media who come across our advertisements.

Key Resources

what key resources do our value propositions require?

Light blue beans, housing/cases that we 3D print or are pre-made for us.
We will need a soldering station wires and buttons to create the technical aspect.
We will need and maintain laptops or desktops to create our codes and function updates.

Customer relationships?

The basis will start with Kick starter, we must keep track of who backed us up and send them progress reports and messages when the product is available, discounts and upgrades.

We will need a Facebook page and twitter to reach as many people as possible and link them to our website.

Value Propositions

What value do we deliver to the customer?

We deliver a product that ensures more safety and a easy music browsing experience on the bike.

Which one of our customers problems are we helping to solve?

We will remove the pain of having to get your phone and unlocking it every time you want to change the music or settings.

How costly are they?

We want to make them available for the general public, we want to aim for a maximum of 50 euros.


How do other companies reach them now?

Other companies aim their products at sportsmen and bike enthusiasts. They sell mostly on their own sites and internet-distribution sites.

Which ones work best?

I think a combination of the channels is necessary to sell this product.
We need to reach the people and show them a product that they didn’t know they needed.

Which ones are most cost-efficient?

The free ones like a Facebook page and other social media are the most cost-efficient.

The most important and expensive cost will be the Light-blue-bean that is the basis of our product.

Which key resources are most expensive?

The Light-blue-bean is the most expensive part, the next one will be the housing/casing.

Which key activities are most expensive?

Programming new downloadable content will be the most expensive because we will need to pay wages for all the hours that the programmers put in.

Shipping and managing sales will also be expensive.

Revenue Streams

For what are our customers really willing to pay?
According to our survey, most people are willing to pay 10-20 euros.
This right now is the biggest problem, because the light blue-beans start at 22 euros if you buy them per 500 units.

We will have to look for cheaper options to realize this product.

For what do they currently pay?
Right now there is no similar product on the market.
Products that come close have more functionality and are aimed for bike enthusiasts and sportsmen. A product that was quite similar is being sold for 200 euros.

Second 3D model

The Design.
After Rob designed the model, I created the 3D models that we 3D printed the next day. I followed the design by the millimeters using the measuring tools in Maya.

The slider.
I’ve had to take a little creative liberty at the slider, because the mechanism was a little unclear to me.




The changes.
The next day we met to 3D print. We talked trough the design and in Repetier Host we looked at the right angle to print the models.
We’ve made a change at the slider because we worried parts would break off.
We doubled the thickness of the walls and changed the height of the slider.


Online Survey-Meda Moisa

I have made an online survey to test our concept and product with the target group.


I have asked mostly questions about the problem but I have also asked questions about the price.So mostly general/important questions that contain the information we needed in order to make changes to the product or to have a more in depth view.

We received 34 answers in total

Those are the results:

In conslusion: most people do have a bike, most people do not feel safe to use the phone while biking, most people chose the cheapest price, most people do listen to music while biking, most people do use their phone as a music device, most people feel uncomfortable to use their phone while biking espiecially when the weather it’s not good and most people chose that they would like such a product that can solve all those problems.

This survey has helped us to improve our concept and idea.
