Jupiter Defiance

Outstanding bike. Many thanks to Dan Sobczak at Kracken Adventures. If it weren't for him I probably would have picked another similar bike. Dan was great. I had a problem where I shorted the battery and he was able to coordinate with Jupiter to get me a replacement battery in less than a week. And thanks also to Jim Stevens at Jupiter for finding the replacement battery. It's a great bike. Very robust. I'm looking forward to using it for many years to come. Thanks
