      Used for 7 to 12 months
      Bought this specifically for getting me to and from work. Was going to get a road bike from a different manufacturer but opted for this when I realiased I could reduce my travel time by going off road for part of the journey. Alterations I have had to make are adding firstly a pair of front and rear mudguards. Didn't want my work clothes muddy before work. I have also changed the gear shifters from the s ram to shimano ez fire. It makes a huge difference, no chain slippage and particularly with the front derailleur a crisp reliable gear selection. Finally I have added a rear pannier rack and instead of a basket a washing up bowl (I know it sounds daft) cable tied to the rack means I can throw my backpack in it for the journey. Obviously none of the accessories I have added were from decathlon but as far as mudguards and pannier racks go I couldn't find ones that suited my needs in the shop. Yes I have made this "mountain" bike into something else but it does get me to and from work without any problems and I am hoping it will last a few good years with a bit of tlc. FYI journey to work approx 7 miles.
