The subsystem approach

2170 Cells

...Tesla has been working on improving its battery technology as well as the supply chain. Tesla, along with Panasonic, has designed a new variety of battery cells called the “2170” which will replace the smaller “18650” cells which have been in use for decades. The new cells provide higher energy densities (meaning that they can store more energy for a given size) and will also be manufactured using an automated process that will help to cut costs. Moreover, these cells will be manufactured at Tesla’s Gigafactory in Nevada, enabling it to cut logistics costs...

Clean Republic has a new 36 volt battery


Can be used with existing Hill Topper kits! They described the chemistry as NCR.
"...Horizon Battery uses a similar type of cell, the NCR (Nickle Cobalt Rechargeable)."
Could be one of the following:

Lithium Nickel Cobalt Aluminum Oxide (LiNiCoAlO2)

Lithium nickel cobalt aluminum oxide battery, or NCA, has been around since 1999 for special applications. It shares similarities with NMC by offering high specific energy, reasonably good specific power and a long life span. Less flattering are safety and cost....

NCR Li-Ion batteries are a new standard in the Lithium ion world. This chemistry of these batteries are LiNiCoAlO2. They are referred to as "NNP" batteries.

Bless Me Anista for it is the spring of the eBike

Bless me Anista for I have seen 9 eBikes in 4 days....

I have seen rear wheel drives in red and blue...

I have seen front wheel drives in black and sand...

I have seen a two wheel drive from an old Spanish cycling company (BH), with both hubs rolling under power, in electric green...

I think this is the spring of the eBike and many are far ahead.

What I see is a diversity of ebike projects

I found a newish thread on Endless Sphere recently. Its about a chineese ebike company called and a guy, Andy Kirby, who has one which he is modifying. I like what he's doing because he is really picking over the power system. And he makes good videos, kinda like Casey Neistat.

Some times you just have to post what's in the wind....
"With a Lithium battery pack one of the most important specifications is the continuous Amp load rating. If your scooter will have two 96 Volt 2500 Watt controllers then these controllers will be able to continuously draw 52 Amps from the battery pack. So a 96 Volt Lithium battery pack with a 52 Amp continuous load rating would be needed."

My First Electric Vehicle (is an electric bike)

For sometime now I've wanted to get into electric biking. I know a lot of cyclists who don't care about electric bike technology as its seen as expensive, unnecessary, trendy and about product bikes and not cycling. I tend to agree with the assessment but find my self intrigued nontheless. This is because I've followed a few other technology fields and have watch as they've blown up in various ways over the years.
Video editing was one such tech as it became possible to digitally edit a movie on a personal computer. The advances in computer and video dramatically changed the way people look at and understand movie images. Ive spent time contemplating glass, gaming, video drones, solar battery charging, etc. what's happening in biking in no less dramatic than those others.

Bikes are becoming computerized or gadgetized. The market in ebikes has exploded as big players in other fields have jumped in to produce products, very expensive products. That's where my fa…
