StumpJumperMax power for this Electric Specialized Stump Jumper mountain climbing machine.  The customer has sent us a number of texts while hitting the trails.  Since this picture was taken we set him up with a backpack approach for the battery…pretty straight forward conversion by either leaving the battery in the case or removing it.

“Doug, man you really undersell the power of these systems. I just hit a local mountain trail…Unbelievable! I definitely love the backpack approach.”
