eGO CYCLE THE STORY OF AN IDEA FOURTH OF A 4-DAY SERIES
Across the water
An idea that outgrew Alabama prospers in the world's bike capital, but the lure of cheap labor may draw it to mainland China. And back in Fairhope, an inventor is toying with a new idea.

I hope this post doesn't get modded "frivolous"...

I know the main idea is to convert kinetic energy into potential energy but I am wondering what effect it has on stopping the bike? The turnkey bikes that I can buy suffer from heaving grossly inadequate braking. I am wondering if I can swap the controller - or convert it - to one that does regenerative braking, will that contribute to the stopping capability of the bike?

I have read many articles in the handbooks and most of them dwell on batteries, or controllers or some other aspect but I did not find one that dwelt specifically on motors. I see pictures of home done conversions but there is seldom detail on why they choose the motor they choose, what makes it good etc.
I know virtually nothing about electric motors - now I know a lot more about controllers and batteries :)
For example:

* Both feet touch ground when stopped
* Adjustable, contoured backrest
* 11" or 17" wide seat
* Aluminum frame
* Dual 26" wheels
* Traditional styling
* Standard components
* 21 speeds or single speed

I worked on the MB-1-E today.
Replaced the 60 tooth hub sprocket with a 72 tooth.
Added a short chain section to make up the difference.
I also reset the controller to default settings.
The new ratio is now 12:1 (was 10:1).
Before the sprocket change I could get up to 20 mph but it took maybe 3/4 block to get up to speed and the bike was sluggish on any noticable hill.
It was getting close to getting dark when I finished up, so I thought I'd check it out on the back street where there was no traffic.

I live in China, the land of the cheap e-biked. I have been tempted to buy one here - can get them for as cheap as $US 120 but the quality and safety (or lack of) has stopped me. Speaking of stopping, the biggest issue is that the braking capabilities of these bikes is not any different from that of a pedal bike, yet the e-bikes are at least 50 pounds heavier and travel at 2.5 times the speed. Below is what I am planning/thinking of. I have not picked a donor bike yet. Please feel free to comment on any point.

The 36V NiMH battery pack on the WE bike is nearing its end so I am looking into a replacement. Before just signing up for another pack I thought I'd try to do something more elegant. Previously I asked about better battery storage and received numerous helpful tips here. Now what I'm wondering is there a battery pack in a plastic shell like the ones that come with the LashOut or BionX that would work with a generic motor and controller? The BionX is great, but I think there is some complicated interaction between the batteries and the other components that would make it unsuitable.

Hi All,
I'll be following up with another chapter in the blog but for now I wanted to let you know that the Bridgestone electric mountain bike got it's new Alltrax controller today.
First thing I did when it arrived was to quickly re-read the programming instructions. Fortunately I received my USB/ Serial programming cable in the mail today as well. It took me a while to find the right XP driver for this cable but finally got that together.

Hello there
I live in Redmond Wa, the bicycle capital of the northwest. I am seriously looking for reviews on the 2007 Izip 'enlightened' line of bikes,or the Currie 'geared hub motor' .Found tons of info on the Currie electroDrive, but the Currie 'geared hub motor' remains a mystery to me, can't find a review or Izip enlightened bikes anywhere, regardless of living in Redmond. I would love it if you would review/compare some of the new or up and coming ready made electric bikes. Some I'm really interested in
