I usually ride in a tarmac with an occasional mild off road, I was using an entry level hybrid bike without front suspension and I feel the need when I ride in a off road or broken road.

The main differences are:

1. DS4 gets suntour NRX suspension with remote lock out while DS3 gets NEX with no remote lockout but lockable at suspension.

2. The front and rear hub of DS4 have Shimano M3050 while DS3 have Formula DC20 alloy.

3. Thé shifter and dérailler*is a Shimano SLX in DS4*while in DS3, it is Acera in front and Alivio in rear.

4. The crank in DS4 is SRAM S1000 and DS3 gets Acera.

Besides, DS3 comes with blue which I like it while DS4 comes only with black.

I am a newbie to the cycling tech, your response will be a deciding factor for me.

Thanks,
Vignesh
