Question: Does this unit have different Assist settings? AKA Something like 10/20/30/50/100% assist? Or is it just an On/Off for the assist?
Document: Very impressed, this is  my first bike with Shimano Gears, disc brakes and hydraulic forks. Very smooth. The only things different than the picture were the head light and the kick stand. I like the head light I got better, its smaller and mounts on the handle bars and has 3 settings.
The bike arrived with the box looking like it had been used as a punching bag. Several large cuts through the cardboard. We opened the box and the bike looked fine at first. As we assembled it, ( easy as we understand bikes and ride 50-100 miles a week.) we could see one major problem. The rear wheel was not round. It was oval shaped and makes the bicycle unusable. We immediately attempted to contact X-Treme  with no luck.
I find that when I pedal, I feel no strain, pressure or pain at all on my knee thanks to the power assist. When using throttle-only, it's like riding a scooter. Surprisingly to me, I find after a good 7-10 miles I feel fresh and refreshed, then when I get off the bike I "feel" the workout of a good bike ride in my thighs and calfs and other muscles, yet no discomfort or pain at all in my bad knee.
There's no way I could lug around that kind of weight on a normal bicycle.Note that the bike itself is heavy (compared to non-motorized bikes), which is both good and bad. It's good because it will protect you somewhat in case you get hit by a car. I got clipped by a car going something like 30 mph (I was going 18), and the only thing that happened was that I tipped over suddenly to one side.
I've had my X-Treme XB300LI for about a week now. I purchased it through a different website (search "farbike") for about $100 less than the price here.
No one in my area wanted to do the respoke,so I contacted a shop in another town, most wanted $100.00 to respoke my rear wheel, I never had the respoke done just true the wheel,and I just kept replaceing spokes,I think I am up to about 50 spokes. I contacted XTreme again and they gave me a $24.00 credit, big deal.
I used to ride my old bike 8-10 miles a day and really miss riding. The lack of activity due to the knee issue contributed to the weight gain, which makes it much harder on my knee. Until I can get medical insurance, surgery is not an option, so I decided to buy an ebike to help me lose some weight and, hopefully, ease the knee issue.I've already ridden 50 miles on it over this week, and I am *adoring* the bike!
Mileage depends on conditions. In steep foothills I've gotten as few as 8-10 miles a charge with pedaling. Flat roads I've gotten over 20.When I take my family biking I turn off the battery and just scoot along with everyone. It is a heavy bike and the battery really spoils you, but no problems pedaling around. I attach my bike trailer and run errands, tow the kids around. I really enjoy e cycling.Bottom line, after adding bells and whistles to my bike it's great.
Regular bikes hurt my knees and push my muscles too hard so I'd quit too quickly. I got a workout today, no doubt. But it wasn't over done and allowed me to stay at it much longer. I probably did 10 miles or more whereas before I might have only done 2 or 3 miles. If you want a scooter, get a scooter. But if you want a mild to regular bike ride (you can turn off the electric assist if you want) than get this.
I've been meaning to get different handlebars/special grips which can fix this.- This thing is heavy. Good and bad, like I said. Bad because you will not enjoy yourself if the battery fails or runs down and you have to pedal it under your own power. Also, you will not want to mess with hoisting it up onto a bus rack or into a car.- Not truly waterproof, though I've been lucky.
Answer: yes
