Story and the Specs:
My experience with an eBike started in
The kit didn't include the battery, of course, so I researched and learned about the new Lithium-Manganese Batteries, and fell in love with them!
Quickly, I designed and assembled my own Battery Pack, complete with its enclosure, using the best possible Lithium battery cells that I could find online. I was very happy when the work on the battery pack was finally done and my first eBike was put together!...
My happiness, though, was short-lived as I fried my eBike's Electronic Speed Controller (ESC), a third of a way on my very first, very enthusiastic e-commute to work, because I treated the bike as if it was a regular moped.
I then spent $38.00 for a replacement ESC, also a Chinese one, that kept getting hot whenever it was put to task on a bit of a extended hill climb. It was then that I realized unless I employed a much stronger, higher power handling ESC, I wasn't going to get that macho, ego pleasing reliability and power that I sought in my eBike.
That realization became even more emphatic, when I relocated to Monterey-
It was expensive, but I was passed of caring for expense in that department! I wanted juice, and was willing to pay for it! So I did not hesitate and got it.
There was still a serious obstacle in the way of realizing my design, I soon realized.
I had to figure out how, which I did with more research and channeling my ancient background in Electrical Engineering, to adapt the new ESC to my eBike application, as the ESC is designed for RC devices. It's circuitry required that I buy and modify yrt another electronic component, and thereby engineer an adaptor that would enable the ESC to power-up my motor on demand without a radio controller. The ESC, that powers mu Bike is designed to be used in high performance, large, Radio Controlled (RC) aircraft and vehicles.
And the dream was finally realized!
Behold a serious eBike that is reliable, fast, and powerful.
One that totally outclasses a moped, and is assembled using high quality, top of the line, equipment.
The Chinese ESC barely allowed 21 mph on a flat surface in its factory kit configuration, and even then I had to be careful not to burn it up. But so far, no one on a bicycle of any kind where I ride my Bike has been able to keep up with me on the road; It kicks ass and takes names, period!
With my 210 Lbs of body weight, it can climb all the way up
Its battery pack provides for plenty of miles on a single charge, of course, the exact range of it depends on the terrain, road condition, and how fast the Bike is driven, and whether or not there was any contribution by pedalling.
The ride experience is simply exhilarating!

Fastened securely in its own compartment, behind the seat above the back wheel, sits a battery pack I made from 12 State-of-the-Art
Nissan Leaf Electric Car
To be honest, I really haven't found myself having to ride this bike to full discharge of its battery, yet. Nor do I feel a compelling urge to do so!
However, to serve as some measure of reference, and based on an academic and experiential knowledge that is now complemented with substantial amount of field experience, I can state confidently that for a rider who weighs around 200 pounds, or lighter, on flat surface, with moderate application of the throttle, this bike should offer a range of 30 to 60 miles, with minimum pedaling. As a good habit, I don't apply the throttle before I pedal the bike into motion, hence, "minimum pedaling."
This battery not only can hold an amazing amount of power, it is also amazingly safe. Lithium batteries have come a long way!
You see in this video what my eBike's battery cells can go through and still function safely:

This speed controller is made in the
other high-end hobby RC applications! It is also easily programmable through a laptop or PC.
Here are some picture I took just before last time I checked the ESC and re-programmed it:
With research through the internet, my own electronics knowledge, and a little bit of experimentation and
engineering, I succeeded in employing this priceless piece of artfully created American Electronics Hardware in my eBike.
I enabled it for wired control, by utilizing a Hall Effect actuated thumb throttle (rather than a less reliable and short-life electromechanical rheostat type throttle) in conjunction with another control device I modified.
It works in conjunction with the ESC to provide 5 volts of auxiliary power for the LED lights and anything else for convenience.
For example, a USB power outlet can be added to it for charging cell phones.
This motor is worry free, even though it is made in
Securely fastened to the fork, it prevents damage from front axle spinning due to the motor's high torque .
I learned the need for that, the hard way!
It is a nice quality mountain bike in its own right, with decent parts.
Of course, the Electrical modifications to this bike can easily be transferred to any other 26" wheel size bicycle.
Here is I, showing the eBike before it was upgraded to 50V:
