Q. How is the performance of ridge in daily use if we travel for 40kms. Does the battery give same backup in long time?

I would categorize it into 3 performance levels for okinawa ridge plus, charged 100%. 1) 0 to 15km would be at high performance with top speed you can reach to 55km/hr. 2) 16 to 45km would be medium performance with top speed you can reach 45km/hr and with descent pickup . 3) 46 to 55km would be moderate performance with top speed arround 40km/hr and pickup also moderate. The good about lithium batteries over Lead acid batteries is that the speed and pickup does not degrade too much in the range you travel. In Leadacid batteries the speed and pickup degrades considerably with drop in charge.

250 to 300 cycles. One year warrenty. Performance good.

Good
