We felt this was important enough to start a X-Treme E Scooter: XB-508 Collaborative Hand Books now rather than latter.
This should make it easier to access all the information we currently have.

Re: New purchase X-Treme XB-508

I see that one website retailer states that the system is 56 amps...guess that means battery pack rating as you indicated...and that the batteries are bigger than those in the xb500. Maybe that does make a speed and hill climbing difference between the two....56 amp bat pack rating, 550 watt motor compared to 48 amp bat pack rating, 500 watt motor??? Otherwise, the xb500 is listed 5 lbs lighter....and you'd think there couldn't be that much difference in performance.

Has your neighbor had any problems with the XB-508 he purchased for his daughter?

No, other than a missing mirror, his daughter loves it. Both parents have Gas X-Treme Scooters, and I'm sure they would like to ride as a family sometimes, and she can't keep up with them on the XB-508, so she very seldom rides it.

Peace Out,

some math for you people to play with
to go 20 miles in one hour with this ebike requres a drop in evation of 983 feet
the 550 watt hub motor peaking speed is 18.8 mph
(road mph) with normal hills, wind, realy stoping at stop signs, and realy waiting for green lights
data from one,two,and three hour range testing (san diego county,ca)
enjoy
