      Hi there, Bought this bike with flat bar. Light and comfortable to ride. Just wondering can I put hybrid wheels with bigger tread? If so which one would you recommend from your shop? Thanks

      A great bike for the price. Good for my 15-50 mile pleasure rides to keep me fit and get me out into the countryside.

      can i put 32t cassette on this bike it is rear derailleur long cage?

      Response of the brand

      Hello,
      Thank you for your question. The simple answer is yes you can. You will require a new chain which needs to be longer than the one supplied. A 9 speed chain costs £9.99: https://www.decathlon.co.uk/9-speed-bike-chain-id_8203903.html

      why new chain?this bike has already 9 speed chain..also can i put 32c tires on these wheels.thank you
      Response of the brand
      You will require a longer chain as the largest sprocket rear cassette has 32t instead of 25t. If you don't do so, shifting will become an issue. The chain width is of course correct (9s).
      Yes, in the vast majority of cases, a 32mm tyre will fit.

      Purchased this after reading lots of reviews on both this and the drop bar version. Bike arrived in just 24 hours of ordering online and required very little assembly. I did have to do a fair amount of 'tweaking' in order to get the brakes and gears just right, but this is as much about preference as it is about functionality - everything worked out of the box, but was only around 80% as good as it was after a hour or so of fine tuning. Now running it on 32c tyres for ultimate comfort and will be using it next month for a 200 mile touring ride.
    • Very good
