Cheetah, old pics

Thought this was part of my blog, found it buried way back in bikes and pedelecs,

The Raliegh, my first e bike, is buried, even further,

Old pics, I, for one, am not a photographer.

Cheetah, Last Hoorah?

How and why did I build this bike? Design limitations

Why, not philisophical, short drive to work. My car would'nt heat up. Hard on a car to make short trips. I knew an electrical bike could be made. I googled, saw what others where building, where they were getting contollers, performance.

Now the How

I built off the work and effort of others. Eric Peltzer had just about what I considered to be the perfect E-bike. I built it. I did'nt do many calculations, just used his advice.

The Rezistor

day_1.jpg
The project has begun! Might as well blog as much as I can.

A friend brought over the Vespa 50S frame last weekend. The purchase also a new front fender (nice!), a new horncast (plus the old one), a new headlight, the seat, rear shock, engine access door, and both 10" wheels, including hubs, brakes, rims, and fairly worn tires. He also gave me the gas tank. Maybe I'll turn it into a trophy for one of my club's future rallies.

Love my little Bike

I ride a home made semi recumbent with a Wilderness Energy 36 volt hub motor.
12 amph slas and a JC-116 controller from TNC Scooters ( the controller that came with the motor was bad and the one they sent to replace it didn't last long)
This is my only transportation and it serves my needs very well although someday I want to go with NICADS.
I am very soon planing on going to 17 or 18 amph batts for the range in cress although I will have to find some place else to mount them.

JDH: My first gas conversion - My eMower

This weekend I converted my gas lawnmower to battery powered electric!

It was really easy. Research involved reading this page: http://www.builditsolar.com/Projects/Vehicles/LeeMower.htm

36v ego!

Just finished all the wires for my ego2 36v conversion. I'm now running the stock ego motor on 36 volts through an alltrax axe controller limited to 100 amps. I replaced the brush springs with heavier springs to (hopefully) make firmer contact and reduce heat at the commutator. I've changed the final drive from a belt to chain for easier (and cheaper) gear ratio changes. the final drive is now 14:36, changed from 22:54, just a slight reduction. my first test ride on flat ground yielded 32 mph in less than 10 seconds.

My Lectra project

DaveB mentioned my Lectra project, and it struck me I haven't written much of anything about it. Unfortunately I don't have pictures handy and in any case the pictures I have are just showing a frame with a mess of wires hanging all over the place.

The Lectra Motorcycle is quasi-historical. They were made by Electric Motorbike (EMB) during the 1990's and that company was later bought by ZAP. I remember seeing them listed on the ZAP website for awhile, and I remember attending a ZAP shareholder meeting where they unveiled the VR36 motorcycle. The Lectra was a 24 volt design and somehow they reworked it to be a 36 volt system. But that vehicle never reached the market, and ZAP kinda mismanaged the product to death. There were about 100 Lectra's made.

I bought it a year ago as a bare frame .. no batteries, no controller, but with a motor and the original wiring. This is a link to the evalbum entry for the previous owner of this bike You'll see batteries in the picture etc, they were Delphi 8v batteries which were basically dead, and Lawrence removed all of them along with the controller before selling me the bike.

I've bought a battery pack of Powersonic 12v 26ah SLA batteries. I chose them because of the bike's geometry. To get to a 60 volt pack there's a section just in front of the motor, where EMB had installed the controller, but into which I'm putting batteries. Those 26ah batteries are skinny enough to fit there. The pack is 10 of those batteries, wired as buddy-pairs so that it's a 60 volt 50ah pack. The pack weight is a bit over 200 lbs.

It has a 72v 400A Alltrax controller which I'm mounting under the seat. The motor is not the original Lectra motor, but an Advanced DC A89. (EVPart's listing for the A89 replacement)

What's wired right now is the batteries, controller, solenoid, throttle, a key switch, a DC-DC converter, some switches to control the keyswitch input on the controller, and the horn. What's left to wire is the headlights and turn lights. Oh, and I need to replace the solenoid because it appears to be ON all the time.

I have original Lectra body panels from Lawrence. But he also sold me something else which is really intriguing.

I've mentioned Craig Vetter and his full fairing's before. He ran a contest for several years for the highest miles/gallon rating that could be achieved with a motorcycle. The winners used a full fairing around the motorcycle, as well as pulling a few tricks like using a "small" (250cc) motorcycle with a motor jimmied for high mileage.

Leaning against my garage wall is one of those fairings. The idea is to cut the plastic bubble to the desired fairing shape and bolt it into place on the motorcycle frame.

So this is rather exciting really. Some portion of that high miles/gallon rating came from the fairing. Motorcycles are, after all, horrible at being streamlined. Having the Lectra streamlined should make for great range improvements.

MB-1-E Part Twenty Four: Schwalbe Tire Arrives

The FedEx guy dropped off my new Schwalbe Tire today.
I pulled off the old tire and placed the plastic tube protector tape in the rim and it barely fit. (32mm wide)
Actually it cradled in nicely and made a nice smooth seat for the tube.
Put on the new tire and tube and put a little air into it.
I pushed on the tire all the way around, rocked the tire from side to side all the way around to make sure that it was fully seated and concentric with the wheel. The tire will accept anywhere from 22psi to 60psi so I put in 40psi.

Why I Ride

I make no secret about my feelings about internal combustion engines and other forms of conspicuous waste. This leads some folks to jump to conclusions about me like I am some sort of extreme tree-hugger or I watched "An Inconvenient Truth" and went off the deep end. I have meaning for a while to write down the reasons I have chosen this lifestyle so here goes.

MB-1-E Part Twenty Three: A Tribute to those who helped me get here and an Update and Summary of the MB-1-E build

Hi All,

This has been a pretty long blog with lots of trial and error and changes throughout the build.
I would like to therefor bring it all together into a summary of where the build stands now, thoughts on future revisions and what I would recommend for others that would like to take on building and electric bike from scratch.
