As I have my own discover DTS_ SI 100 I experienced that it’s body is not so strong. Like it’s chain set has very low life. Moreover 5 gears setup is also very bad thing because it effects the pickup when we exerlate it. Milage is very good as I experienced that it provides the 80 kmpl milage and seat is also very comfortable. So I have just one suggestion for the improvement that body should be hard and chainset should be improved. After that it is very effective bike totally value of money
