As I called about,  was wondering about the electric front bicycle wheels you had. Can one buy either a bike motor or would buying an entire front wheel with a motor already included ? 
If I got a bike motor for the front wheel of a mountain bike, say as an example,  Model:HBL-16,  exalt how would this be inserted into the existing spokes of the center of the wheel ?   
Whether the entire motorized front wheel can be bought or just the front wheel hub motor, how do the controls with a front wheel differ from a back wheel motor ? 
How water proof are these motor hubs ?  How long does a motor of 36V/48V and 750W/1000W  they take to fully charge and how long would the charge last ? 
 
The options of Shipping seem fine, though I am not a whole-seller, so I assume I can buy just one or two items at a time. I also do not use paypal, what other methods of payment may I use ?  

Your E-bike company may just be what I’ve been looking for a while now, though I have a least another set of questions before I attempt to make a purchase to ship over. 
I’m still having some troubles determining on your website exactly the difference between which motor hubs are for the front vs the back wheels.    
I only want to get the front wheel set up at the moment, though ultimately the back wheel motor I’m guessing should have a little more power than the front wheel,
or should it be eventually an equally balanced between the front and the back wheel ?  (maybe I should go for a 24 to 36 volt in the front and a 36 to 48 reserved for the back.
 
You’re right when you point out that I should have the necessary kit accessories set-up to go with the front bike motor, such as a battery which I hope to mount somewhere
in-between the bike’s triangle bars, which I will also need a mount bracket for the battery I assume., along with a speed controller and If my existing gears won’t do the trick,
then maybe special gear shifts added to the package. I don’t know if I want get the entire front and back conversion kit at this time, unless it  would be a bit cheaper and easier
to buy the front and the back as a whole set with the accessories, as I can always leave the back wheel mechanism in my closet for a time and just install the front motor.
 
You say most of your motor hubs are fairly rain proof but not exactly mud puddle proof ?  Same I guess would go for the Battery cases.  
 
I will check things over again on your site along with the shipping arrangements, but I may still have to call you to confirm my slight back vs front wheel confusion. 
 
I may still buy both the front and back wheel hubs, along with whatever else is needed. As long as they could be put together separately, though that may require two separate 
batteries or is one battery good enough for both wheels ?  However, I was wondering just as a kick-start, you wouldn’t happen to have a front wheel-Hub with the battery included 
within the wheel motor case itself as part of a front wheel ?   (This isn’t what a Motor:brushless hub is, about is it, a battery contained within the wheel motor hub itself ?
