Great thread, also on endless_sphere.com

THANKS!!!

I checked with their Aliexpress site, but it was cheaper to order directly.

I'm not 100% on this. I am still learning, but the batteries used are
eon lithium ICR21700 cells and the BMW is 150amps. I am getting a 10 amp charger, which will take about 10 hours from empty to fully charged, so I am told.

Yup, and ADVRider, and EBR.

Since I am going electric, I would like to swap in all LED lighting to reduce the load. Does anyone have a list of part numbers for the stock bulbs, and even maybe LED replacements? I tried a search, but failed.

Unless there is something limiting the charger besides its output, such as battery temperature, it should take about 4 hours. Shouldn't get to hot as your charging at a slower then the standard charge current according to the manufacturer. Doesn't hurt anything just takes a little longer. If your using the 34 amp hour battery mentioned earlier and the charger is 10 amps @ 72 volts. The first phase, or the bulk phase should push 10 amps of constant current until the battery is about 80% charged or 27.2 amp hours or 2.7 hours at 10 amps. This leaves about 6.8 amp hours to put back in the battery. Depending on the charger and its capabilities, once a cell reach 4.2 volts, it should switch to constant voltage and hold the voltage for each cell at about 4.2 volts and decrease the current until a preset cut off for current is reached. Usually that setpoint is a percentage of the charging current so the charger may stop at 10% or 1 amp of current. That's why you can charge a dead battery fairly quickly to 80%, but it may take an hour for that last 20%.

Good info. I am a bit of a noob on this. My ebike charges in about 4 hours from empty. 10 ah battery and a 2.5 amp charger.

The first 80% or 8 amps, should take about 3.2 hours, 8 amp hours/2.5 amps = 3.2 hours. That last 2 amp amp hours takes about 0.5 - 1 hour. Sounds like that's about what the math would calculate out too.

A little spot filler to fill in the scratches and dimples!

Ready for primer. I can't go any further until I receive the primer. I wont paint it until I have all the electrical in place for fit. I may need to do some more fab. Next up the front suspension and rear shock. I have a new handlebar holder and cover, so minimal work there.

Lookin good.
One comment - for a watch point.
Since you needed to use some filler on the floor board - be super careful about leaving it at the junction of floor board and tunnel where the tunnel's steel's thickness sits on the floor board.

The seam will flex with use - and any filler that is there is prone to cracking after paint/use (in my limited experience).

Others more versed can comment/ correct. This scoot body has come a long way already.

This particular filler is POR 15 seam filler. As with most fillers, most of it will be ground off, but I hear you.

Thanks,

Battery maker just finished the battery. I should have it next week.

Battery looks awesome.

Was Daly Electronics the source (reading the badge on the BMS, but too lazy to google)?

I looked it up, and yes. Here is a link. My battery guy has them.

Another example of an electric motor within the Vespa gearbox.

The wiring on the scooter will be all new. This is my current (pardon the pun) take on it.

For the motor, battery and controller electrics:


For the scooter electrics:


Motor electrics borrowed partly from the internet.

“20 D Energizer batteries”^^^

Parts are starting to come in:



DC DC converter from 72V to 12V. Amp/Volt/Current meter. 300amp circuit breaker.

this is so far over my head but I am loving following along with it!

Looks promising!
Given that its going to be much more silent - I would consider a horn upgrade.
I'm sure you're familiar with the two most popular air horn blasters.
I have one on my sidecar - and it will stop a person turning right out of a parking lot in front of me - dead in their tracks.
- I recently had someone look me right in the eyes - then start to pull out - and the horn shocked them enough that they still stopped - just out of pure confusion.

Thanks for the second vid on geared version.
Familiar with that one.
Pretty nice execution - tho gearing still seems to high in 1srt anyway - but overall impressive in my view.

same.

It is a learn as you go kind of deal, like 2-stroke tuning. I am better at electrics!

Definitely. I have this on my BMW GS:

exactly.
no nonsense effective.
thumbs up emoji if they had one on here to hit.

You need an external speaker hooked to a recording of a bicycle with a card in the spokes. Have it playing while your in town.

Oh that would be funny. Or I could have a bluetooth speaker and play Harley sounds!

which horns are those, btw?

CM2 you are one funny dood. What are the details on the horn and can you hide them easily on a vintage stock scooter?

Awesome!

Smaller than many of the air horns, and very well made. My put it under the left rear cowl.

Thanks again to Resistor for helping me work through the motor wiring. I think I am getting close. I completely redid the motor diagram, and updated the bike wiring. I am using a new fuse block, and completely hand wiring the bike. I plan to reuse the switches as much as possible, and adding a device that will translate the throttle cable to electrical impulses to keep it stock as possible looking. The clutch lever will be repurposed, or replaced, with a rear disc brake set-up.




Just waiting on all the parts to come in. So far I have the Inverter, 72V to 12V 25 amp, the main battery cut off, and the amp/current meter in hand.

Battery should be here this week, and the motor and controller plus brake mechanicals next week.

I used this one.
Have on sidecar - but I suspect it could have been tucked under rear left cowl or even under rear fender in some fashion - so it is exposed.
Made the error (more than once) of removing the chrome handlebar switch and accidentally setting off the horn in my garage.
Sphincter tightening loud.

That is the standard for air horns. Mine is as loud, but 1"+ smaller in every direction. Fit my BMW GS much better.

Nice installation as well judging from the pics.
Smaller + just as loud = better for vespa.
If that's the case - I would go with it.
Once you are DC - it's one of the nice available upgrades.

I use this horn for my electric: https://www.amazon.com/FIAMM-72112-Freeway-Blaster-Note/dp/B000DINKPQ/ref=sr_1_3?dchild=1&keywords=freeway+blaster+horn&qid=1610420420&sr=8-3. It is pretty inexpensive, small, doesn't require a relay(I use one anyway), and sounds like a car horn. I have it mounted under the right side cowl, but it could be mounted almost anywhere except in the horn cast. When I accidentally set it off in the garage, my wife comes out to find out if I'm okay.

The reason I mention it at all is that in traffic, you want the biggest badass horn you can get. But when you are riding in a residential neighborhood, your scooter is quiet enough that pedestrians cannot hear your approach. Touch the horn button and an air horn will require said pedestrian to change their pants. To quote Spiderman, "with great power comes great responsibility".

I was on the freeway with my GS and a lady had the phone to her left ear as she blindly started to merge into me. I hit my air horn and she was so startled that she accidentally threw her phone out the open window and swerved right. I thought it was pretty funny at the time. Later my wife asked what would have happened had she, in her fear, swerved more left. Sobering thought. I am more careful using my horn these days.

Been there haven't been there!

I am cautious about just blaring it at people.
I had a horrible incedent pulling into Starbucks tho.

Sunny day.
People all out front sipping coffee and chilling.
Had entire crowds attention - as the sidecar often gets.
Space was in front of seating area - no more than 5 feet away.
I cooly reached to press the kill switch - and in a daydream - hammered the horn button.
Oh man.
The fear & shock.

Profusely apologized as I removed helmet.
So so sorry!
oops.
