INDICATE YOUR TURN velorian bicycle turn indicators

It all began at the end of 2016 with the Bicycle Turn Signal project. After looking at the solutions available on the market and finding nothing satisfying, I built my own solution, just like I have seen some of them in the streets of Berlin. What I was missing was recharging the battery via the hub dynamo, so I looked for Development Partner .

The finished electronics has a housing that is easy to attach to the frame and includes the connectors. The battery part can be removed and recharged with a common USB cable like the mobile phone at the power outlet. Thus the hub dynamo is not a prerequisite. Selected especially small 12V LED indicators, matching switches and specially manufactured indicator holders make the system flexible for the diverse world of bicycles.

As a battery, a standard Li-ion battery is used, which can be purchased at many electronics retailers. This battery can be replaced at the end of its lifetime. The charging electronics uses intelligent software to ensure that the battery lasts a long time.

The cables of the indicators and the switches should be joined together at the handlebars to form one cable. This is done in the velorian cable box, which can usually be placed underneath the handlebar stem.





Such a development must be tested under real conditions. Many friends support me in this and have already found weak points in daily use, which are being eliminated bit by bit. We are not satisfied yet....

Egon tests since October 2018

Egon tests with connection of the flasher unit to the hub dynamo. With him, the indicator mounts are installed at the front on the Bowden cable brakes and at the rear on the luggage rack. He is an occasional and fair weather rider and therefore has to recharge the battery every few months at the socket.

Florian tests since August 2019

Florian tests without connection to the hub dynamo. He has installed a first prototype of the indicator holder on the saddle, which holds well. The temporary front indicator holders had become necessary, after I had heard about his hydraulic brakes at short notice. My mountings for the bowden cable brake did not fit with it. The result looks a bit rough, but fits optically to the mountain bike. His feedback so far has always been positive.

Eike tests since August 2019

Eike tests with connection of the flasher unit to the hub dynamo. With him, the indicator brackets are installed at the front on the Bowden cable brakes and at the rear on the luggage rack. So far there were no complaints from him.

Holger tests since August 2019

Holger tests with connection of the flasher unit to the hub dynamo. His bike is the problem child. Constantly something at his turn signals does not work or a turn signal breaks off or the battery is not charged. But he is also the most intensive tester. On his bike, the indicators are installed at the front with the temporary indicator brackets and at the rear on the luggage rack.

Stefan tests since April 2020

Stefan tests with the connection of the flasher unit to the hub dynamo. In his case, the indicator mounts are installed at the front on the Bowden cable brakes and at the rear on the luggage rack. He is a frequent rider and uses his bike for all routes through the city.

Romy tests since Juni 2020

Romy is testing with connection of the flasher unit to the hub dynamo. In her case, the indicator mounts are installed at the front on the Bowden cable brakes and at the rear on the luggage rack. She rides her bike through the city anytime and anywhere.

The D-Line has the same options as the others Turn Indicator from velorian. Here too, it is possible to reconfigure between button and switch operation, whether 2 or 4 installed flashers. Also the D-Line shall get a USB charging port. The current state of development will be shown at most of the Bicycle Fairs we visited. If we are finished and satisfied with the test results, there should soon be a kickstart campaign for this as well. Subscribe to the Newsletter in order not to miss the further development.
