      I looked at many bike computers and eventually chose this one. After reading hundreds of reviews for many different computers I felt this was the best scored one and did everything I needed. I advise buyers not to get too hung on functions such as temp, wind speed etc I think if u want everything then you need to spend serious pound to get a good one. This one does the basics very well and looks great. A proffesional design and very clear display makes it look amazing on my racer. It comes off the cradel very easily aswell. Very easy to install with no tools. Uses bands which I was aprehensive about at first, but havent budged since I fitted it.

      PROS - looks great, competitive price, does what i needt it to, easy to install
      CONS - none

      Would recommend this product, hasnt let me down yet after my 6th ride. Dont be fooled by much cheaper ones, these seem to give bad readings of 70mph on stationary roads, £15 - £20 and a quality name is needed.

      4.0 out of 5 stars A good basic cycle computer
      Reviewed in the United Kingdom on 29 July 2010
      Verified Purchase
      Got this as my first computer for a bike as I'm used to having useful data at my fingertips in the car. I went for this model as the wired connection is a lot cheaper than wireless, and the latest models can upload to a PC (note that this requires a cradle and software available seperatly for ~ 30).

      Installation was straightforward when following the supplied instructions. It's important to get the sensor matching the wheel magnet and close by (under 5mm). For my bike that meant mounting lower than expected. All it's doing is getting a pulse when the wheel passes, so it doesn't matter that it's halfway down the fork. It was a little confusing selecting my wheel size, but once figured out no problem and won't need doing again. It seems to work well, starting when I move off and stopping when I stop. The buttons are a little tricky when on the move, but all cycle computers would have the same issues. Removing it from the bike is no problem, and it's light weight.

      A couple of points that lose that 5th star for me: No details on the upload to PC (read the Sigma website to find out it's more hardware and software); It's always on, when I expected to be able to turn it off, although it does just show the time. The battery is suposed to last 2 years.

      There are cheaper cycle computers around but this one seems fairly well made and is certainly good value for the price. There are clear instructions in English as well as the usual strange diagrammatic ones and I had no problems fitting it. I would recommend getting some cable ties rather than the supplied 'O' rings for attaching the computer itself and the sensor unit. You can also use them to make a tidy job of securing the cable. I had to fit the sensor quite a long way down the fork to get within the required 5 mm gap between it and the bit that goes on the spoke but I cannot see any problem with that. Unless you have strong young hands some radio pliers or something similar will be useful for fitting the bit that goes on the spokes. Setting up and operating the device is initially a bit confusing, but no more so than with any other small electronic device like this. I have only used it once so far but it seems to work perfectly and went up to almost 20 mph quite happily.

      This is by far the worst piece of equipment I have bought on here:-
      1, it does not come with the cable ties required
      2, instructions are so confusing you feel like giving up before you start
      3, putting the battery in was far harder than you would expect
      4, as for programing it find a spare hour or 3 just keeps jumping back to beginning
      5, setting the magnet on spokes distance is tricky but that might be my bike

      and I haven't even got out the house yet because of cosmetic damage I caused trying to fit the battery there's no way I can return it will probably just buy another one this time might just take it to shop and have them fit it save all this stress and frustration. Have even let the wife have ago she cant get it right either.

      Its a few hours later with some help from "you tube" its up and running and I am very impressed with its large display and other feature, so have upped my rating to 3 stars it should be complete with the 4 cable ties needed so deduct 1 star,the poor instructions loose another star don't know what I would have done without "you Tube".

      but after all that I am very happy with it.

      5.0 out of 5 stars Excellent value bike computer
      Reviewed in the United Kingdom on 7 August 2012
      Verified Purchase
      This is the third Sigma bike computer I've bought, it's quite a bit cheaper than the others with fewer functions available, but ideal for my purposes - it's for my second bike. All I want when out and about is distance travelled and speed etc. This little beauty does all these and more, and is very easy to set up - mind you I'm used to the rather cookie manuals by now, so if this is your first purchase of a Sigma computer, you may find it a wee bit tricky to start with, but do persevere as it's very intuitive to use once set up. Assuming your tyre circumference is listed, it's a 10 minute job to attach and you're away - if your tyre isn't listed, you'll have to get the trusty inch tape out to accurately calibrate it so you will have true readings when on the road. Have some cable ties available when fitting to secure and tidy the wire between the sensor and the display.

      In short a great little computer at an excellent price - happy to recommend.

      Installation:

      Die Installation ist recht einfach, wenn man weiß wie es geht und, wie ich, schon einen Computer der Art montiert hat. Die Anleitung ist bebildert, jedoch sollte ein Laie etwas genauer hinschauen um die Piktogramme zu entziffern. Wenn alles glatt läuft, ist die Montage nach 15min beendet und man kann sich an die Einstellungen machen.
      Hier ist der Reifenumfang essentiell und die in der Anleitung enthaltene Tabelle eine große Hilfe.

      Gebrauch:
      Die Funktionen reichen vollkommen aus, wenn man lediglich wissen möchte wie man aktuell unterwegs ist (Zeit, Geschwindigkeit und Entfernung). Hilfreich ist auch die Gesamt-Km Angabe für Rad 1 und Rad 2, falls man mit 2 unterschiedlichen Reifensätzen fahren sollte (von mir aber nicht genutzt).
      Die Lesbarkeit ist sehr gut, der Kontrast individuell einstellbar und bei Bedarf kann die Displaybeleuchtung eingeschaltet werden.
      Auch die Bedienung ist nach kurzer Zeit einfach und übersichtlich (bei 4 Knöpfen kann man nicht viel falsch machen).

      Alles in allem reicht der BC1009 für den Hausgebrauch vollkommen aus (optional ist ein Sensor für die Trittfrequenz). Die Lebensdauer der Batterie ist recht lang.

      5.0 out of 5 stars Nach Testphase gleich noch einen zweiten BC 1009 gekauft! :-)
      Reviewed in Germany on 13 August 2013

      Meine Freundin und ich haben uns neue Fahrräder gekauft. Weil ich auch mal sehen wollte, wie viel km ich damit zurück lege, wie schnell ich bin u.s.w., musste ein Fahrrad-Computer ran.
      Und wenn man gerne Rezensionen studiert, bleibt man eben beim BC 1009 hängen. :-)

      Also EINEN gekauft, um erst mal zu sehen, ob er was taugt. Montage ist wirklich kein großer Akt. Erst mal Display/Controller am Lenkrad und Sendeeinheit an der Gabel mit beiliegenden Gummis oder mit Kabelbindern (ich komme noch dazu) befestigt, Magneten an die Speiche und geschaut, ob sich was tut. Wunderbar,-lief!

      Wenn man wirklich genaue Werte haben will, muss man den Controller erst mal auf den RICHTIGEN Radumfang programmieren. Dazu kann man den Wert über die Einstellungen-Taste unten links genau einrichten. Bei mir z.B.
      2.215 , was 2,215 m bzw. 2215 cm Radumfang entspricht.
      Diesen kann man mit der altbekannten Formel: Durchmesser x Pi (3,141) berechnen, was aber eher ungenau ist.
      ODER, man macht es ganz genau:
      Bandmass ausreichender Länge auf ebene Fläche legen. Anfang genau mit dem Ventil auf 0 cm Höhe und dann das Fahrrad genau entlang schieben, bis das Ventil wieder genau unten steht.

      Diesen Wert eingeben, auf stets guten Luftdruck achten und es ist fast so genau wie ein Navi.
      Zum Testen hatte ich nun fast 300 km die beiliegenden Gummiringe zur Befestigung genutzt, aber seit gestern ersetzt durch Kabelbinder, die natürlich nochmal deutlich fester fixieren.

      Und weil meine Freundin auch so begeistert war, hat sie vor ein paar Tagen ein amazon Überraschungs-Paket mit dem gleichen Gerät von mir bekommen.
      Auch bei ihr läuft der BC richtig toll.

      Fazit: Preis-Leistung super! Was will man mehr als diesen, auch bei greller Sonne sehr gut ablesbaren Fahrrad-Computer?!

      Wir wollten eigentlich NICHT im Regen Fahrrad fahren, aber wir sind in einen richtig heftigen Regenschauer hinein geraten und der BC 1009 wurde recht nass. Zumindest dieser Regen hat ihm nichts ausgemacht. Bin froh, das Teil gekauft zu haben!

      Nice product for bike riders.
      Easy to use and large, very readable display.

      Some work required on the initial set up the unit and the manual is a bit confusing with so many languages interspersed in the small manual. Should have one manual for each language or separate language sections in a single manual.
