I purchased the bike 2 months ago. The bike shop said it was a demo, gave me 30 percent off. The bike had 5 miles on it. It 140 on it now. The problem is the power keeps turning off. About every 5 miles, its starting to get on my nerves. I think battery is bad because I checked voltage on battery while on charger top off it at 48. I disconnect charger voltage drops to 46 volts. funny thing is the dash board is saying fully charged 5 bars also side of battery. I also own 2014 Neo Cross with 1900 trouble free miles. I knew going in that izip wasn't top off the line in quality. And I see only 6 month warranty on battery. to bad because the bike is a lot of fun a real good climber.
