Giant New Zealand country manager Jason Foster said the e-bike was a complete redesign of the previous model.
The improved frame and geometry of the 32km/h bike meant trickier spots could be reached and the recovery process sped up.
"The old bike was a previous generation but now these guys have more confidence to go down much steeper, more technical trails to get to someone in a remote location."
The First Response Unit aligns with one of the club's goals to be more inclusive for everyone.

Rotorua Mountain Bike Club secretary Barbara Jenks had been a part of the first response initiative from the beginning and was ecstatic with how much it had progressed.
Jenks said having the first responders gave people confidence to mountain bike.
"Quite a few families are happy for kids to ride in the forest knowing that the first response is there.
"It's fantastic. It'll be here forever."
Half of the funding for the responders comes from ACC with the other half from various sponsors and donations from the public.
"But the upgraded bike was a donation," Jenks said.
The responders are alerted to an incident when called on 0800 WHAKA 1.
The response unit also promotes prevention of accidents and encourages people to talk to them.
What started with aims to maintain the reputation of the Whakarewarewa Forest's world-class trail reputation, the Rotorua Mountain Bike Club has broadened to be more rider-focused.
