Electric Honda Elite

A couple months ago I found an old Honda Elite frame available for real cheap on Craigslist. I'd just gotten a motor from deafscooter when he was clearing his garage for the trip to China, and was wondering what to do with it. This motor was said to be 48 volt, 4000 watts, and so this Honda Elite frame seemed like the perfect thing. It came already stripped, and when I picked it up the guy turned out to be an EV person himself. His daily driver is a Solectria Force and this Honda Elite was something he'd converted to electric years and years earlier, but he wanted to get rid of.

MB-1-E Part Eleven: More Wiring

Hey All,

I finally got my batteries all wired with the DPDT switch so I can charge at 12V and run at 24V (both nominal voltages, as we all know AGM SLA's are a bit higher than that at full charge).

So I now have two battery banks, each has 4 - 9Ah 12V batteries. Each bank is in parallel and the two banks are wired in series through the DPDT switch.
Thanks to a few electrical wizards here I was able to get this right and it works like a charm.

I'm charging the full set right now using my Iota DLS-15 charger with QD4 three stage charge controller.

MB-1-E Part Ten: Jackshaft & Controller arrive

Hi Again,

The Jackshaft assembly finally arrived today.
I received the controller a day or two ago.
The chain sprocket has a freewheel for coasting.

MB-1-E Part Nine: More parts arrive

Still waiting on my jackshaft assembly and controller to arrive, they are both shipping out of Canada and it takes a while, I'm finding out.

I did get my new ESGE double kickstand today and got it installed. I like it!
It will really help get the chain drive and sprockets set right since it lifts the rear wheel off the ground.
Seems pretty stable and folds up nicely on the left hand side of the bike.

I ordered a 72 Tooth sprocket for the rear hub so I'd have a variety of sheaves/ sprockets to gear things up/ down as needed.

MB-1-E Part Seven: Securing the batteries connecting them up.

Hey everybody,

The past few days I've been pretty busy, so didn't have a lot of time to get a much work done on the Mountain Bike.

After working with the acrylic enclosure for a full afternoon, I abandoned the idea. I got all the pieces cut and started gluing it up and then simply changed my mind.

MB-1-E Part Six: Original battery placement

Greetings,

Update: After a few emails and a couple of phone calls, I've been assured that everything is/ will be on it's way here. Glad that's all straight now, my blood pressure is back to normal.

MB-1-E Part Four: Electric Mountain Bike

Hey All,

Today I worked on the lower attachment for the chain tensioning rod.
I've abandoned the spring loaded adjustment for a rigid approach, it was fun and IMO looked kind of cool but, as my expert sources have suggested, "It ain't gonna work".

I've decided to put an adjustable rod on both sides of the bike now which will help sturdy things up and provide some additional motor shaft alignment adjustment.

I think some 1/2" conduit will become the support rod, while a 1/4" bolt in-line with the rod will provide adjustment at the lower end.
