Whether on the road or on the cycle path, it is getting more and more crowded. Cycling in a big city like Berlin makes special demands, because you are rarely alone on the road. Seeing and being seen, especially in the dark, is more important than ever. The dark season is over now, but the next one is sure to come.
The velorian e-bike blinker set also fits on e-cargo or recumbent bikes, on an e-bike or S-pedelec.
Basically all LED motorcycle turn signals up to 1.5 Watt can be used. For the upcoming kickstarter campaign, two chaser indicators were selected for the front position and two small, bright indicators at the rear. The experiences from the test drives, some of which took years, show that the rear indicators should always be rather small and have a flexible attachment. This increases the age enormously. For the same reason, the front turn signals also have a flexible attachment.
It is operated via two buttons on the handlebars. Pressed once on the left, the left indicator flashes until the same button is pressed again. Otherwise, the indicator goes off on its own after two minutes. This time has so far been sufficient for each traffic light phase. A change from left to right or vice versa is simply done by pressing the other button.
If both switches are operated, a warning flash starts, which stops after 15 minutes, or can be stopped at any time by pressing any switch. The sound of the video is switched off. Switch it on by clicking on the speaker symbol in the video image to hear the flashing click.
The connection to the power supply and the connections between flasher box, buttons, indicators and power supply are made with the flat plugs proven on the bike.
The lengths of the connecting cables have been chosen so that they are long enough for an optimal mounting position on the bike even on a high frame. Up to the velorian cable box (see below) 50 cm cable is available, up to the rear turn signals 160 cm and up to the power connection 100 cm cable. The cables are shortened to fit the respective bicycle frame during assembly and only then are flat plugs and insulation fitted. For cargo and recumbent bikes these cable lengths can be dimensioned differently on request.
The cables on the turn signal box are replaceable. If one cuts off too short during the assembly, this is annoying, but can be repaired by screwing on the housing and inserting a new longer cable.
During the test phase it became apparent that a status LED on the handlebars too often required a view of the handlebars from the road. That's why the indicator box has a sound generator that makes the flashing audible. The tone sounds almost like the flasher ticking in a car and is just loud enough to be heard while driving. The sound of the videos on this page is turned off. Turn it on to hear the flasher click.
Why cable? Because the battery can be used on the e-bike. This eliminates the need to check and recharge additional batteries before starting the ride. The velorian e-bike blinker set works with an input voltage of 6 - 48 Volt direct current, it is therefore not suitable for connection to a hub dynamo.
The current requirements of the StVZO in Germany for indicators on motorised two-wheelers, multi-track bicycles and the EMC directive for e-bikes are fulfilled. The StVZO does not (yet) provide turn signals for single-track, i.e. completely normal bicycles and e-bikes.
The electronics of the velorian e-bike blinker set are reverse polarity protected, so nothing will break if the plus and minus connections are reversed. It simply does not work. Likewise, the battery and motor of an e-bike are usually protected by multiple fuses. Because of the low power consumption of the velorian e-bike blinker set, the connection can be realized very easily at the headlight cable, as the following series of pictures shows.
Some e-bike drive systems, such as Bosch, measure the consumption of the connected headlights and have defined a maximum value for this. This value must be determined beforehand with the specialist dealer, as the drive system can issue error messages if the load is too high, and correct function is then no longer guaranteed. This maximum value should not be exceeded by the indicator and headlamp together when mounted on the headlamp connection cable. The velorian e-bike blinker set has a rated power of 5 watts when all 4 turn signals are flashing.
An essential part of the solution is the velorian Cable Box. In this box, the cables of buttons and indicators on the handlebars are brought together to form a single cable. After connecting the cables, they are secured internally against pulling to prevent the contacts from loosening by pulling on the cables to a certain extent. The cable box is also secured with cable ties.
how to mount velorian Cable Box
Various indicator brackets made of sheet steel and aluminium were developed and tested, because no two wheels are the same. Mountings for turn signals on the handlebars, on the bowden cable brake lever, and on the luggage rack have been provided so far. The bracket on the handlebars combines the switch and the turn signal bracket, as shown in the video below for mounting the universal bracket. Generally a relatively straight handlebar shape is required. Further different mounts also for cargo bikes and recumbents are in development.

The velorian e-bike blinker set works with an input voltage of 6 - 48 volts and is compatible with any e-bike battery.
The velorian blinker set can be easily connected to the headlight cable. We recommend installation by a specialist dealer.
It is operated via two buttons on the handlebars. Pressed once on the left, the left indicator flashes until the same button is pressed again. Otherwise, the indicator goes off on its own after two minutes.
Blinkers make your bike safer. With chaser indicators, your bike is right on trend. The flexible turn signal arm prevents premature breaking off.
If both buttons are pressed, all indicators will flash a warning flash for 15 minutes.
The velorian e-bike blinker set is CE conform to the norms and standards CISPR12, ISO 11451-1, ISO 11451-2, DIN EN 15194 and tolerates outdoor temperatures from -20 °C to +75 °C. It meets the current requirements of the StVZO for indicators on motorised two-wheelers, multi-track bicycles and the EMC directive for e-bikes.
