## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    A good one
  

*by M***I on Reviewed in India on 22 October 2018*

I was happy to see its look at first glance but after using it for 4-5 days, its disk brake started making noise which is not expected from a new cycle although overall its performance was quite good as I expected.The bottle had a lot of scratches.I got a non-rechargeable light which has fine brightness., bottle, bottle holder.The build quality of tyre and frame is impressive.

### ⭐⭐⭐⭐ 







  
  
    Good MTB for the price
  

*by S***A on Reviewed in India on 22 May 2018*

The bike feels good... no problems so far... but the seller should have mentioned their contact details so that we could contact them for after sales spare parts etc....
