    • Great mountain bike

      Neil (United Kingdom)
      Used for 1 week or less
      This bike really is a tough thing. After a bit of research i found that Decathlon bikes trumped Halfords is almost every area.

      I'm 6ft and i went for the large model. I was almost temped by the XL, but the seat was at its lowest setting and the reach to the handle bars was just a little stretch.

      I would strongly recommend sitting on the bikes first in store before you purchase in case you were looking to buy online like i was. I'm glad i bought it in store. The man even set it all up checked the nuts and bolts were tight and adjusted the gears and brakes. Even replaced the seat clasp as it was a little scrated.

      The only negative side to this bike is the saddle. Its ROCK HARD. It was getting painful after just 5 minutes. This is something i will deffo be upgrading soon. New saddles are cheap enough on amazon.
    • Excellent Bike For The Price!

      Used for 3 to 6 months
      Good bike for on and off road! Brakes started to squeal after a month, but couldn't complain as they had plenty of use, I have recently changed the brake blocks to a set of pro Clarks, £5, and the squeal has stopped and stopping distance shortened, The bike is really good value for money, light weight and the front suspension absorbs punishment well! I recommend this bike to all.
      Great Sturdy light weight Bike, had it 2 months!
      Squeal on the Brakes!
    • Lovely to ride

      Used for 2 to 8 weeks
      This was a gift for my Son who loves it. On Christmas day he persuaded me to go out for a ride with him, me using his older brothers (more expensive) bike, I tried both bikes out and the rockrider is a much nicer ride. Customer service in store was excellent too
      Good value
    • put up in shop

      kye (United Kingdom)

      Response of the brand
      Hello Rahman,

      Thank you for reviewing the Rockrider 340. The issue you have come across sounds like an issue with the set up of the bike. Take the bike to your local store to get them to fix the issues you are having with the bike.
