Yup the mounts are going to be interesting. If it ever stops raining here I could get the bike frame out of the shed. This was in the mailbox today 30tooth rear sprocket. I like shiny parts. My front sprockets are still on the boat coming from Taiwan. Think I got the slow boat.

Just thinking out loud here. Would it compromise the motor if you removed the four bolts on the drive end and used a longer bolt? You could machine a hole in some plate to clear that tapered face and then bolt the plate and motor back together. You could then weld to the plate in whatever fashion you needed to. If you have access to a lathe with a large enough 4 jaw I would turn the compound slide to match that taper and get MORE surface contact. That would also make for a repeatably accurate placement so taking apart and re-assembling wouldn't get you out of alignment. Can't really see the other end so no idea how to support that side.
Wonder what's under that black ring in between the 4 bolts? If that's a solid structure you machine a slip fit sleeve that could fit around it with 4 ears to take advantage of the existing bolts. IF that's solid under there, that would be a pretty rigid mount. Would still need something on the other end though.

I was born and raised on Venus & I may be here a while.....
Under the black trim with the four bolts is the gear reduction (supposedly the three small gears can be changed out for 4:1 / 5:1 or 6:1 ratio- I haven’t investigated that any further.
The motor itself has a good sturdy base/ it’s a one piece metal shroud w/fins for cooling.
The other end has a fan, sealed shaft on bearing/ it pulls/pushes air past the ridges.
Pics- a couple are not mine:

Excited to see this done!!
Ok, yeah that's not strong under there. I would stick with a face plate and longer bolts to compensate.
You weren't wrong. Mounts are going to be interesting for sure.
I wonder what the manufacturer has to say about mounting?
Probably....we got your money, you're on your own.

Yup there isn’t much info/ I really need to dig to find what I’m looking for. I’ve been lurking on gocart/elec conversions forums and scooter forums for some good info though. This “Should” come together ok.
At first I wanted to put gocart wheels on the back with 10” pvc water pipe sections over the tires. Woulda been fun but limited where to ride it (pavement).

Gee, a lathe, Hmmm, that would be sweel - Who's got one of those??
This is perfect timing, I've got Brians frame just about done, 2 350X heads to fix in the mill, and last is a run of 250R head light guards to make, but those are no hurry.
I had thought about this when I saw the Alta electric dirtbike, should probably read up on those.
Next up, the "Shepelectric" trike...
EDIT - Did I mention dad's an electrical engineer?? He's good too...

The Alta Drive and Battery:
That's a big battery!! 1 to 3 hours run time...

Well, I placed the motor in/ close to where it needs to be(within 1/2 inch anyway). The central weight of the motor is very close to center of frame(good), the rear brake pedal “should”be ok too. Odd that the top back motor mount is near perfect dimension as top back bolt of elec motor. That should be used when figured for mounting. The fan side will be fine for foot peg (I took the fan shroud off but it’s pretty flush w/fan when installed.
I’m still waiting on the correct front sprockets, there getting closer(NY) should have em by Wednesday. So I still can’t do much until then. I’ll put the tripple on today (yup I’ll be dropping little balls I’m sure) on second thought maybe not it’ll be in the way (hit my head on it)....
Here’s a couple pics:
So far so good
Edit: got some front sprockets delivered today-

That is too cool, can't wait to see the progress! I've been wanting to do this for a long time now. Would be cool if you could get the motor mounted on the swingarm. Perfect weight placement. How much does a motor like that cost?

Motor was around $250 but have seen the same motor listed for 400 ish on other sites.
actually thought about mounting it on the swingarm, but I need to keep some weight upfront to keep the front down “just Incase” I put the battery pack in a six/pack style grab bar.
Also this will have the stock suspension so a possibility of bottoming the frame onto the motor if it was mounted back on the swingarm wouldn’t be good.
Not necessarily looking for a wheelie machine.
No real progress I gotta do this thing called “work”
The elec motor sprocket will be in the same location as the stock engine sprocket so the suspension moves without interferance. Well u know what I mean.

I'm digging this project
Hey Shep let me know if you need some help with the machined stuff you might need

Still gathering parts, but I’m getting close to a roller- still need to purchase a front hub though. I’ve been replacing bearings and seals as I go, no paint until final assembly- “learned that the hard way”
Thanks for the offer ironchop, I just need to get my butt down to “crashers” but work keeps getting in the way!!!!!!!
Recently picked up another set of those “foot fence” peg guards for this project- think I spent more for stainless hardware than for the actual guards. 83/84 250r axle is waiting to be used also.
The company I’m purchasing the brushless motor “controller” from will fill it with a resin so it’ll be waterproof/ so that’ll help. Just a $15 fee.
I might as well use these old stock nuts I bought a while ago just hate to open it....(just need the washer(shim) still
Thanks for looking
Edit: a few days later-
I decided to paint the swingarm, install the bearings and the correct seal to accept the 250r axle.
Need a new slider though, I’ll have to get one for final assembly.
Just paint after a good clean up.
And edit again: I’ve got a 520 pitch front sprocket “thank you” steve...for lathe work
.....and have the rear axle ready to go. The rear hubs are in the mail. I’m waiting on front hub bearings and seals also. Pics:
I figure next I need to cast from alum a front sprocket cover, I think that’ll be next before winter sets in.

I'm loving this project so far! $6.50 for the axle nuts haha that was a great deal - I've never seen the foot fence before and I've been riding since 1980, it's an interesting item for sure!
