Congrats! Very impressive and can't wait to hear what you get for mileage on a full charge, and how long it takes to charge on standard outlets.

Lots of hard work paid off.

Thanks, it has been both fun and frustrating. I had to wait on the dongle that should have come with it, and programming was a pain from my phone, plus I somehow wired the brake backwards keeping the motor from turning. Last ditch I cut the brake wire to the controller and it worked!

Now for the fun part. Putting it all together and getting a ride!

Thanks guys! I got it mostly back together today. Cleaned up and sorted the wiring, and installed the body pieces. Everything works except the power gauge. I popped it by crossing a wire.







Still need the leg shield trim, and a few minor items, but it is ready for a test ride.

Not perfect, but pretty damn good.

I took it out for the first road test, with just the front drum brake. I have not bled the rear yet because I wasn't sure it is was going to be OK. So far it is, but I need to upgrade the front because it has no chance to stop in any safe way with this new set-up. It stutters and is poor at slowing the bike with no rear.

So, anyhow, with that in mind, I took it for two 3 mile loops. All back roads limited to 25mph. So, of course I gave it the "gas". All I can say is damn, this is at least twice as quick as the old two stroke. I got it up to an indicated 44mph, but ran out of road (due to the poor brakes) to keep going faster. I suspect, with some tuning of the controller, it will make 55mph indicated. I will put my GPS on it for the next ride to get real speeds. Nonetheless, this thing is way better (except for brakes) than the old motor, and a lot lighter too!




This week I add the safety (brakes) and do a bunch of little clean up items, but I can say it is a success for my limited skills.

Congratulations! You've transformed that machine is a big way. I remember seeing it for sale, then it was gone, then you posted it up here. What an awesome journey to follow along on.

It'll be fun to see floorboard runners, brakes, and the scoot in urban jungle settings.

Great job man!

Do you have regenerative braking setup?

I'm really enjoying it. My wife has a sidecar license, and I am strongly considering adding a sidecar to it for her to use for work. Should be more fun, and I can add more battery capacity.

I do, though I have not done any optimization yet. It is like a low compression low HP motor back - pressure bike. Not overly noticeable.

Good to know, I was thinking if it's brake activated you could turn it up a bit to help with braking. Also what did you use for front brake shoes? A few people here have mentioned a softer pad with better braking.

Stock shoes. I think I need to break them in, and adjust them more.

Today was fun. I bled the rear brake, then added my GPS to the speedo with a suction mount, then went for a ride. The brakes are much improved since I have the rear disc, which got better and better as it bedded in. I took it on the main road and went as fast as I could. Keep in mine I am 275 pounds, and a big wind break. Still, I managed an impressive speed for having to done any mods to the programming.

Here is the GPS mounted, upside down to get some video.



Here is the GPS speeds, which are slightly faster than the speedo.




52 mph is not bad at all. I am confident that I can get more speed out of it.

In 8 miles I used about 10% of the battery, but this was a lot of stops and starts, all at nearly full throttle. I think 50 miles is doable. The battery and the motor stayed cool.

Lots more to do, but I am quite happy so far!

For those interested, the weight of the scooter is now 212 pounds, around 100kg. Original weight of the p125X was 240 pounds. So I am lighter by 28 pounds. Top speed on the gas motor was 86kph, or 53mph, basically the same as mine. HP was 8, mine is around 15, but apples to oranges as the electric bike far out accelerates the gas bike.

In other news, I installed the LED signal bulbs, so they are good to go, and added some trim, and found a mirror for it. I will wait to post more photos until all the trim is on it.

Jim - remarkable job really.
And perfect scoot to do it to.
Nice P2 motor for Chandlerman came out of it as well!

Interested in your opinion of the riding experience.
Video would also be fun to see to get a sense.
You've got bigger bikes - so this is likely mostly a grocery getter - where I assume it is best.
Have always been concerned I would miss the riding experience with electric.
What's it like?!

I plan to ride it this coming weekend, when the weather is good, from full battery to near empty. I will take it on speedy roads and in town to try to get a rounded feel of it. I will have my gopro on it for video.

From my 12 miles so far, all I can say is that it is a lot of fun. Nearly silent, quick off the line, but from 10mph on, a near rocket. It tries to lift the front if I do not lean into it. For reference, I am 280 pounds, so I would imagine it would be faster with a guy half my size on it. Once up to speed it is smooth and tractable, responsive to throttle and steering input. The small tires make it slightly twitchy, but that has nothing to do with being electric.

So far I have not touched the settings. I will likely trim it with just a bit more power off the line, and slightly less as it spools up. Hopefully I will have my amp/volt meter hooked up to get an idea of the power usage when at different throttle inputs.

To your last comment, I am a 40+ year gas motorcycle rider, but extremely limited two stroke scooter miles, and I can say the electric is so much fun that I do not miss the noise and feel of the gas motor.

Thinking about putting this rack back on, but I am undecided. It is functional, but not very aesthetically pleasing.

If you go sidecar, no need for a rack...
You can fit a box of wine, or multiple large bottles of Vodka and a Hendricks in it just in front of the seat.
Ask me how I know.

Basically done. Added trim on the front, fixed a disconnected wire, cleaned it up and installed the volt/load gauge.












Tomorrow I plan on a long ride to test range and endurance.

So, successful ride, and here are the stats:

94% charge:


Starting miles, 17144.5


End miles: 17169.2


Total miles: 24.7

End charge 38%.


Moving time, 57 minutes, total time 1:21 minutes, with an average moving speed of 27 mph, and a top speed of 62mph.

None of that tells the whole story. First, it was all in town with stop and go traffic, with one short freeway ride (top speed run of 1.5 miles). The bike was perfect the whole time. Took off quickly, accelerated briskly, and easily kept up with traffic from 35-50 mph. At not time did I feel like traffic was outrunning me, and many times I outran it. It was a total joy to ride. Good handling, and plenty of acceleration.

What makes the test not realistic, was heavy Sunday DC traffic, with a lot of stopping and starting, with nearly full throttle each time. The bike weighs 210 pounds, I weigh 275, so this stopping and starting was hard on the battery. If I were to take it on back roads and leisurely riding, I am sure my miles would easily double. I was watching the amp gauge and noted that I hit 150 amps several times, and during acceleration I was generally over 100 amps.

Next weekend I will take it on some backroads out of the city, with far fewer stops and road speed limits around 45. I am confident I can get easily 50 miles out of it!

Here is why I do not have a GPS log to prove the ride. It happened 2 miles from home when I hit a big bump and it jumped off the bike, then got run over.


Start and stop of my amp gauge. For some reason it defaults to 100ah. I need to find a way to reset it.

Before:


After:


Interestingly, there appeared no degradation of performance as the battery got lower. The top speed run was done just a couple of miles before the crash of the GPS.

The good thing is that I have several more old GPS'. I will have a tether on the next one.

That said, great ride, and proved the bike is solid. I need to align the rear brake, and adjust the front, maybe turn off regen to see what effect it has. But overall I am very happy. I am going to try to take it to Bikes and Breakfast for a showoff, and maybe Cars and Coffee in MD in a month or so.

Big congratulations on a successful ride and build! This was truly an impressive, not only due to the quality, but the project speed. Amazing in every way!

I hope you performance numbers will convince some others that this is really a thing and we'll see a few more of these electric conversions extend the lives of these machines we love. I also believe more people might try it if there were a reasonably priced, commercially available swing arm. How do you feel about a side hustle?

Thanks for letting us watch--it's been an interesting and fun build!

Next up.. smallframe ebike conversion? That will solve some of the weight issues with a smaller foundation! Maybe even get some wheelies out of one...

Jim,
Fun to ride along and what a conversion from the rust bucket of a beater you started with.

Thanks for sharing all the details.
Good genII road map for others interested.

Really curious about how hot sounds and feels.
Do you feel prone with it so quiet?
Is the regen braking weird?
And can you modulate the acceleration nicely or does it have somewhat a nothing or go sensation to the throttle?

It has been an adventure, and with lots of help, especially you. I do know that we have inspired at least one more to go for it.

As for the swingarm, if I were a better welder, or had a simpler design, I think we could sell a dozen or more. The swingarm is definitely the hard part. If you just buy one, small frame a large frame appear to be the same, the actual work on conversions are easy if you do not have to rewire the whole bike! I am sure I could have saved myself a lot of time just using the factory wiring, with a few small mods.

Oh, and the speeds are a big bonus! Now to test the battery endurance.

Thanks, I plan to put together a full video, and make available free plans for the electrical and swingarm.

It has a small hum, that at speed is mostly hidden by wind noise. Certainly they do not hear you coming, if that is what you mean? But, the traffic around here doesn't hear anything anyhow.

The regen actually does make some sound, and it feels like weak engine backpressure braking.

The throttle is very easy to modulate, similar to a motorcycle, with a slight surge at around 10-15mph if I have it pinned. I believe I can adjust that out with the controller. With my weight it is a tad slow off the line, so not going to surprise anyone, but it is a smooth throttle and easy to modulate.

Looks like fun, out of pure curiosity, I looked up that Kelly controller. It looks like if you felt like it you could get an 84 volt version of that controller. Add a few cells to that battery and get more torque, higher top speed and a longer range with the larger battery. When I emailed the motor manufacturer, they said 96 volts wasn't an issue.

So, out of town all week and I was itching to go ride. Beautiful 70 and sunny!

Started the baseline with my new, old, GPS, properly secured this time.




I took local roads out 16 miles, with the speed limits 40-45, I was doing that and more, easily keeping up with traffic, but there was too much traffic to do a speed run. I did hit 52mph at one point.

When I stopped I checked my battery and was like oops!


That may be pushing it.

I turned around and headed back, when traffic cleared up. On a slight uphill slope I went for top speed. Managed 60.2mph. Not bad with volts down to 74V.

This bike is just a blast to ride, and therefor I was unable to keep my wrist out of it, and was riding hard right from the beginning.

12 miles later I found my range when I ride it hard.


Note that I rode for 55 min, with on time of 1:16 minutes, and an average speed of 30.3. Like I said, I was dogging it.

Problem is, the bike refuses to go when I hit 5% battery!


The other problem is, my battery monitor is not accurate:

The voltage is right, amps are right, but Amp hours and percentages are off. I can't seem to reset them correctly.

Result?




Total bike miles. Now at 17198, or 64 electric miles.


I need to do a little more tweaking on the controller. I also need to contain myself and see if I can ride more sedately for a distance run.

So 28 miles range when constant stop and go fast accelerating? Sounds fun, but really limited to short rides. Wonder what a similar 30-40mph constant speed ride's range would be like? Maybe trailer it out to a nice rural road and get 60-70 mile day out of it? That would be fun.

Also curious if there is a way you can get an adapter to use a tesla charging station or something? Cause if you are limited to a common household outlet you might be pretty restricted unless you can pull up to a random business with an outside outlet and siphon off some power!

I'm pretty confident that I could ride 40mph for a solid 45+ miles. My issue is a lead wrist. I do have a 3 poll switch that I can hook up (I wired it but left it unhooked) that will moderate my power. I noticed I am climbing up to near 200 amps under hard acceleration, usually going uphill. If I tone it down, I would do much better.

This is definitely a city bike. The current charger takes 6-7 hours using 4 amps and 110V. The battery would not allow a Tesla style charge. The BMS isn't designed for it. I can use a 10 amp charger, and been good in about 3 hours, but it is hard on the battery to use 10 amps all the time. Slower charging helps prolong the battery life. I am seriously considering another battery. I can fit it under the right cowl, which is now empty.

Oh, I forgot, I get up to 32 amps in regen, and barely need the brakes. That is set at 20%. Takes some getting used to though.

Jim - terrific recap.
Can imagine how much fun it is to just have torque galore at your wrist.
Ultimate grocery getter as is.
Suspect that with the higher regeneration settings and stop and start, you will actually get more millage then wide open roads - due to the regen.
Thanks for sharing.
Very cool build.

Vespa people will see it.



I also adjusted the caliper on the brake rotor to "hopefully" eliminate the low speed brake howl I have.

Thanks. I do plan to see what 30% does, though I suspect it will make braking awkward.

I am looking for a small rear rack in chrome to carry small items to make it more useful.
