A nicely put together bike. Recommended.

A nicely put together bike which I've been riding a couple of times a week for several months now without any problems. Lightweight and modern (at least compared to previous bikes I've owned) it has done everything I've asked of it. Recommended.

Fast, light, cool

I like it a lot and my son says it looks cool. First road bike I have bought, very happy so far.

Decent bike, awful wheels and tyres

Had this bike for 3 months now, bought it in August. Riding it has been great and the bike and been good for a beginner with nice disc brakes. In the 3 months I’ve had 2 punctures on the front wheel. The first one happened after 20 miles of riding so I immediately took the wheel back to the shop where the tyre was cut off by the staff and replaced with a more expensive and nicer tyre. The next puncture happened 2 months later during riding whilst I was out. It took 3 men to get the tyre off the wheel, we tried at least 4 levers and eventually got it off after 30 minutes of levering and pulling as hard as we could. I understand now why the staff in the shop just cut the tyre off the wheel as it was a nightmare to get the tyre off. I’ll definitely look at getting different wheels for the bike as the ones it come with are not fit for purpose. Other than the poorly designed wheels the rest of the bike is lovely.

Excellent bike

Initially this was driving slower but found the issue was with brakes being tight. Got it fixed and now it rides smooth. Very happy with the purchase and Decathlon's service.


Pedal came off on my first ride, highly dangerous and I was very lucky as cycling on a busy road. The bike looks and feel ok and believe more of an issue of the person putting it together. Strongly advise against anyone buying a bike from Decathlon Greenwich, how this was not spotted before they told me the bike was ready is unbelievable and shows very poor workmanship and the bike mechanic takes no time or value in the work. I hope others have a better experience with this bike from elsewhere but I will never buy a decathlon bike again.

Tyres/Wheels are a nightmare

Pleased with the bike apart from the wheels which will not take any tyre other than the 28mm tyre supplied. I wanted something slightly wider, the spec says the wheel is compatible with a 32c tyres however i have tried three different tyres all of which cannot be fitted as they are too tight. The 28mm tyre that comes with the bike is very difficult to fit too, i am not the first person to comment on this. Getting a puncture at the roadside would be a problem! Decathlon please suggest a wider tyre that is not smooth that will fit the wheel.

Super obchod, dobrá cena.

S kolem jsem spokojený. Dobře se na něm jezdí. Vše funguje jak má. Kolo doporučuji.

Super Rennrad für Anfänger

Es ist mein erstes Rennrad. Ich fahre es seit 3 Monaten und es hat nun über 600km und fährt noch wie am Anfang.

Preis-Leistung Super

Man darf natürlich für den Preis kein High-end Fitnessrad erwarten. Aber ehrlicher Weise muss man sagen, daß es für einen Hobbyfahrer ein super Rad ist für den Preis. Die Lieferung per Spedition würde super angekündigt und hat perfekt funktioniert. Nach dem auspacken fix die Pedale ran und Lenker richten. Vorsichtshalber zum einstellen auf den Ständer gespannt - war in meinem Fall aber vollkommen unnötig. Perfekt eingestellt. Nach der ersten Runde komplett positiv überrascht.

Tolles Rad, schlechte Voreinstellung

Ich kann mich den anderen Kommentierern nur anschließen: Das Fahren des Rads macht sehr viel Spaß, die Gangwechsel sind flott, wenn auch etwas laut. Die Größe L ist für meine 1,78m Körpergröße nicht zu groß. Einzig die Bremse vorne scheint mir schwach zu greifen. Insgesamt bin ich sehr froh über meinen Kauf. Problematisch war die Einstellung der Bremsen und der Schaltung von Werk. Die Hinterradbremse griff leicht auch ohne Betätigung, einige Gänge waren nicht nutzbar, die Gangschaltung schliff hörbar. Als ich mit diesen Problemen in die Filiale kam, wurde das Fahrrad sofort für 20 Minuten in die Werkstatt genommen. Das hat mich sehr positiv überrascht. Was mich nicht positiv überrascht hat, war dass die Gangschaltung immernoch schliff, wenngleich die Gänge jetzt reingingen. 2 Stunden später griff die Bremse hinten dann so stark, dass man nicht mehr mit dem Rad fahren konnte, ich musste das Rad nach Hause tragen. Das kann keinem Qualitätsanspruch gerecht werden. Lösung war, die Schraube die den Bremsdruckpunkt einstellt, zu entfernen. Für die schleifende Schaltung werde ich selbst Hand anlegen, glücklicherweise kenne ich mich ein wenig aus. Ich denke sie würden es auch wieder reparieren wenn ich zum Laden ginge, ich habe allerdings auch noch besseres zu tun, und eine Gangschaltung, die nicht richtig funktioniert, ausgeliefert bekommen, habe ich jetzt ja auch schon zweimal. Also Rad top, Voreinstellung miserabel.

besser als erwartet

Macht Spaß

Holgura y protector

Escribo de nuevo otro problema que tuve con mi bici en poco tiempo. Apareció una holgura en el eje de pedalier de 1 mm aprox. Así que la llevé al taller de nuevo. Por otra parte el protector de plástico que lleva entre los piñones y la rueda trasera se rajó así que pedí que me lo quitaran sin más. Me preocupa el tema de la holgura, espero que quede solucionado. Veremos...
