Just want to confirm, when I purchase this bike it actually comes with pedals? I do NOT have to purchase bike pedals separately?


Correct - pedals are included in with our bikes.

By Thierry on Sep 5, 2023 | STAFF


Is the small size ever being restocked?


Unfortunately, not in the near future, But the RC100 is available.

Could I add gravel tiers to this bike? Do you sell them?


This bike is not desgined to offer the clearnace required for gravel tires

By Thierry on Sep 18, 2023 | STAFF


Would I be able to swap the tires on this for some more aggressive tires if I wanted to do some gravel riding?


You can put some wider more agressive tires on this bike, if you have the clearance so it would depend the width of the gravel tire. up to 30mm you should be fine

I had to come back and do...

I had to come back and have the derailleur adjusted. The gears were not shifting correctly. The front brake is already making noise. I don't find that the disc brake brakes "hard". Kind regards.

Everything is alright

Driven almost 300km

Since I'm a complete beginner, I don't have any great comparison values, but the drive and chain always cause problems. No matter how set, the chain jumps to smaller sprockets when driving hard. As soon as a lot of force is used, the bike is almost unusable. I'm very disappointed and wouldn't recommend it for sporty driving. Ok otherwise not usable for the bathroom or shopping trip.... Unfortunately very poor quality parts were installed that show a lot of wear and tear. I would love to return it and buy something real.

What I was looking for

An ideal bicycle for beginners. The size range is great. I am 1.93 tall and wear XXL. It's great for comfortable and relaxed driving. The range of the sprocket and the 2 chainrings is very versatile and the different anchor points and the wide wheel arch allow you to convert it into a simple Gravel or a bike for touring and bikepacking.

All good and quick

I'm very satisfied, I know a little bit about it. Only the rear wheel was tensioned too tightly and it started to whistle while driving. Solve readjustment done!

Great buy

I hesitated and looked at more bikes. I was just starting out in road cycling and I want it for not very long weekend outings and some more days. For price and features it was unbeatable and I finally ordered it through the Decathlon website. After having it for three months, the bike is incredibly good, robust and works perfectly in any situation: downhill, changes, etc. Very happy with the purchase. I consider it to be a bargain in the world of bikes (very inflated prices). I recommend it. You can also make improvements if you want and you can even switch to gravel. You can not ask for more.

The bike is pretty good for the money

I have ridden about 1500 km with the bike and I am satisfied. There are a few mistakes that could be improved and probably the biggest one is the brakes and their efficiency is weaker and I would probably give a 10 wheel with a larger size in the back if you ride in a more oscillating style. I use it for trips along cycle paths, sometimes it can also handle some dirt or gravel roads. The seat is quite comfortable. Overall, a solid bike for not much money

Super bike

Value for money, and with disc brakes, great!!

Failure with shipping home

They sent it to me from a store and not from the warehouse, I arrived home without protections, with the gear bent in a worn grip and the handlebars scratched, the pedals hanging from a flange and an alarm placed on the frame... the next day the I took it to the store, and they took it to be fixed a month later when I went to pick it up, because no one noticed in any way that it was already in the store, I find that they haven't fixed anything. The after-sales service is a disaster, and in theory it is under full warranty.

Don't expect too much from it

You can't expect much for the purchase price, but after 2,000 km the rear wheel hub plus the cones are completely worn out. I took proactive action to replace the hub myself. Then called Decathlon but no compensation is possible. My advice, spend the extra money and buy a better brand

3 uses already broken

Bought new, used three times, in town, both pedals are already broken and the rear tire is flat....

Good product for beginner

very good bike for beginners, who wants to try cycling without breaking the bank. I put my butt on it and rode on a hilly 60km course in Auvergne. no problem for the different gear changes and chainrings. good braking on descents (it must be said that I am small). as for climbs and flats (there weren't many) good reaction from the bike. Very happy with my purchase. To see in use.
