I have the largest BionX D-500 kit with an 8 pound, 557 watt hour battery. It allows me to ride like a 25 year old again........for about 45 miles. It does not make me lazy. It's torque sensor rewards me more the harder I ride, thus I ride fast and hard again to reap the benefits. I use just moderate levels of assist with occasional higher level blasts over steep hills.
But 45 miles is just not enough range to embark on a loaded bike camping tour. I'm guessing that range would be even less after adding 25 pounds of gear. I'd need to find accommodations at that interval with electricity every night. That would mean no state parks, no USFS campgrounds, no hiker/biker sites and no stealth camping. I doubt that one would even find a motel every 45 miles. I'm hoping that regular riding locally with the assist will strengthen my leg so I can go back to unassisted cycling. My doctor says that will not happen.
Jack, I wish you the best and I'll be following your log to see how you make it happen.
edit: after reading canalligator's link I am a bit more encouraged. Limiting the assist to level 1 along with the BionX regeneration feature seemed to add a lot to that rider's range. That said, he was traveling light on a credit card trip and had a place to plug in every night.
