Question: Thanks! Answered! Can you take the battery out to charge or is it fixed on the bike?
Document: The battery is 7 pounds, and can be removed fairly easily from its housing. You do need to use the key to unlock it before you can take it out of its housing. You don't need to remove it to charge. I have taken some photo of the lock, hopefully, I will figure out how to upload to Amazon.RidingThe bike is fairly well made, but on the heavy side.
Extremely well made, high quality material used for this bike. Great battery charging system, easy battery removal, can travel quite far on a single charge. Definitely met my expectations.
There was a time I was on my bike for around 10.4 miles and it took almost 5 hours to charge to full.I haven't really calculated how many miles I could push on this bike but it was able to run at least 10 miles without pedaling for me. I might update on this later.I added a milk crate to the luggage rack and strapped it down with 2 bungie cords.
The battery is half the cost of the bike.Overall I am very pleased with the purchase. Would definitely recommend.
This has been a very nice bike for almost a year already.The bike is somewhat heavy, but folds and does everything that we expected it to do. Speeds are about 14-17 mph and that really is enough for me on a bike. It is plenty fast for city riding.As far as the battery goes:Anything with a battery is prone to having issues and the battery itself could be a problem eventually.My battery remains strong after almost a year.
I really like this bike. I liked it so much, I ordered a 2nd one for my wife.PackagingIt came in a box, folded up, and protected by a bunch of thin wrapper (to prevent scratches?). Everything except for the seat was  in 1 piece. To assemble, just remove all those wrappers (which took about 10 minutes), and unfold the bike, put the seat post in place, and it was ready. The battery was already full.
I have not figure out the range of the battery yet. My ride from home to work is about 10 miles, and at most it dipped into the yellow range.Accessories/DocumentationThe bike came with a manual, but that's about it. It is very difficult to find more documents online or elsewhere. I did purchase another charger from Amazon for less than $15. Just search for 24V 2A Scooter battery Charger with XLR connector. In my case, the charger works beautifully.
Performs great. Folds and unfolds easily. Has yet to run low on battery power. Very compact for our RV or the back of the car. The only negative is the seat is very uncomfortable.
If anyone has any information, I would really appreciate hearing from you.Update 11/6/2013I rode it home from work yesterday and left it without charging. I rode in from home to work today, and it started with battery at "yellow", and but the time I got to work, I can see some "red". But as soon as I stopped riding, the battery is at "green" again.
These are a quality piece of engineering. We received two of them and have already ridden over 100 miles. My wife and I are avid cyclists. We use these when we travel to keep from renting or borrowing someone else's junk. They are fun, reliable, extremely well made, and user friendly. Assembly is a snap. Mileage for the battery is underestimated. We use mostly pedal assist. Even after a 4 hour ride with assists, the batteries show green. Excellent product.
Answer: yes
