Endless Sphere

well i want to run the motor at the 48v range so i would need to go with more than one pack, i was hoping to at least get 20min. im just building the bike do thrash around infront of my house maybe right it like up to 10 miles if thats even possible now.

how long of a run time could i expect with light throttle with a 5000mah battery?

alright the plan is to run this motor http://www.hobbycity.com/hobbycity/stor ... oduct=5139 with the 160a castle creations esc. My question is what lipo batteries would you guys recomend?
