Using the computer to find a road bike of the brand Centurion Hyperdrive 4300 Bj. 2012 in the colors white / red / black. But you can use at any other bicycle him.
The cycling computer will start immediately when riding a bicycle. You do not press countless buttons. Operation is simple and easy to understand.
Scope of supply:
-----------------------
1 bike computer incl. Bracket, wireless radio transmitters, power magnet, 2 rubber bands and 2 x CR2 button cells (1 each for transmitter and computer), manual with tables and sketches
Features:
-------------------
The Sigma BC 8:12 ATS has the necessary basic functions
- Current speed
- Average speed
- Max. Speed
- Trip distance and total distance
- Time
- Total travel time
- Start / Stop
He fulfilled perfectly so far these functions. The comparison of these functions with a more expensive bike computer showed no significant deviation. All specified functions are working properly and sufficiently precise.
Style:
-------------------
Visually, it looks like any other bike computer of Sigma. Simple white on the front and 1 large function key in white, which makes the menu with the individual sub-items by turn.
Assembly:
----------------
The wireless bicycle computer can be grds. easily install without tools. These 2 rubber rings are supplied (for handlebar and fork).
The bracket can be mounted on the handlebar with one located at the bottom of the computer tape and a rubber ring or with cable ties. Alternatively, you can also attach the bracket to the handlebar stem (then but with tool).
Since my bike the handlebar is quite thick wrapped with handlebar tape, none of the rubber rings supplied was used. I have therefore the hardware store to get more rubber rings yet. At a handlebar with normal diameter, the rings should however fit easily.
The power magnet is attached to a spoke, the transmitter with another rubber ring on the fork.
The distance between magnet and transmitter should not exceed 1.2 cm, be the distance between the transmitter and the computer no longer than 70 cm.
Assembly time took me about 25 minutes (wg. Above problem with the rings).
Those who do not get along with the installation instructions supplied by the pictogram can watch a video for mounting also on YouTube, so it really should each get him properly attach the wheel. Has helped me to do this in advance of the Assembly.
On YouTube there are following Montage video (link can not be published):

Operation and construction:
-------------------------------------
The computer has 2 buttons (back and front top left below)
On YouTube there are the following adjustment video (link can not be published):
SIGMA SPORT BC // 8.12 / ATS // settings
Back top left:
With this button you can calibrate the basic settings. If three seconds you press it can language (7 languages), Km / h or mp / h, set the time, total km, total time and the wheel circumference.
If the computer is set once one needs this button only modify basic functions as needed to set the time to daylight saving time or adapt.
An operation of the button is only removed from the holder at Radcomputer possible because the button can not be achieved with mounted computer.
Face down:
With this button you can switch the functions daily (day-Km, duration of the tour, Average km / h Max. Km / h) back and forth. Can be effected both at a standstill and the wheel while driving.
Furthermore, you can delete the daily records. Either you choose the function you want to delete and delete them or you hold the button for about 3 seconds and there are all daily data deleted.
First time setup / programming:
-------------------------------------------------- -------
On delivery, the computer is in a 'deep sleep', from which he is aroused by pressing the button on the front for about 5 seconds. Then you can adjust with two buttons available modes.
The wheel circumference can measure itself (in the operating instructions with pictures explains) or read by the size features on the sides of the tires having a value from a table of operating instructions and type.
Operation when driving:
-----------------------------------------------
It is operated by means of the function key on the front easily and after 1 '2 trips intuitively, even with wet hands on the wheel. Even with the onset of darkness the display can still be easily read.
It takes the computer are not afraid that you get lost in any sub-menus, because all these functions are sequentially displayed and are well labeled. The name of the function is therefore wrong. eg travel time, day Km, Max. Km / h etc.
If one has briefly dealt with the manual and the computer, you can then operate it intuitively.
Conclusion:
------------
For 22.85 a wireless bike computer of Sigma to get with the above features is ok. The price-performance ratio is absolutely right here.
After about 9 months of use I can so far, except for the 'small teething problems' during installation, nothing negative to say, and therefore remain in the allocation of maximum 5 out of 5 stars.
The build quality also makes a stable and high-quality impression.
Should important news in everyday use of the Sigma cycling computer give (defects etc.), I will report here of course.
Update 7/14/2014:
---------------------------------------
The cycling computer is now 12 months in use, still works without problems, yet no battery change.
Have at the time about 25 trips with distances between 20-202 kilometers in the border region Rhineland-Palatinate (Southern Palatinate) / Alsace (Bas-Rhin) / Lorraine (Department (Moselle) completed With advance planning and follow-up measurements of the routes on Google maps. there have been no deviations in the measurement kilometer in each tour compared to the graphics displayed on your computer during the trips.
Even the longest tour in mid-June 2014. Bitche / Lorraine about 202 kilometers fitted with the predicted total distance on a return trip.
Update 6/12/2015:
-----------------------------------------
The cycling computer is now almost 24 months in use, still works without problems, yet no battery change necessary so completed tours as above now approx 45th
Only permanent deviation:
------------------------------------------------
The speed runs on the display while driving with permanently. There is a separate query of the maximum achieved speed. In various experiments Sprint was noted over this separate display speed usually 0.5 to 0.75 Km / h slower than the current display while driving.
