(Not Really) Finishing my Electric Moped

[@ollysworkshop]

I can relate to the standing around for 15 minutes moving things around, then actually doing something for 5 minutes. Lately though I seem to be spending several days just looking at things, and achieving close to nothing! Great video though. Glad to see the bike running.

[@John-v2d3b]

Take a leaf from my book. My shed has everything neatly hung up on the floor! That way you know where everything is because you have to step over every time you move😂.

[@WoLpH]

I've got a Prusa MK3/s and a Bambu A1 mini and I can tell you... the A1 mini is mostly free of complications and just works, but it still not 100% problem free. But it's finally moved from a project to a commodity for me. An A1 mini is about 200 euro, it's honestly worth giving it a shot, I've rarely been more impressed by a product.

[@anthonygrodecki7968]

Yep your puch looks fun. I did mine a few years ago, I use it nearly every day but I do live in the Netherlands. I get about 90km per charge but a lower top speed of 25khm ( the legal top speed). Mine is rusty and I am constantly having to fix bits. But for me it’s fun and I think that’s part of the point. Thanks for sharing 😊

[@Nderak]

spend many an afternoon at college watching my brother try to figure out motor cutoff by brake application. i was of little use to him.

[@osgeld]

I have a pretty nice 3d printer ... trade it in a heartbeat for a decent metal break and a welder

[@maakmeneer]

Very nice project! As a comment to removing the wires for low and high speed, I found out some while ago that the standard setting for these type of controllers is the "medium" speed setting, so if you want some more speed you can solder the "high" pad to the ground pad next to it to make "high" the standard speed setting

[@Mad-Duk_Machine_Werkes]

The Brake arm that the end of the cable mounts on is sometimes SPLINED, you remove the arm, and "clock" it backwards one or two splines and it solves the Cable being too long syndrome, sometimes?

[@JeremyMakesThings]

That makes sense. I’ll have to look into it sometime(s)

[@raymondjames9734]

love it! I would name it the Puch-e and pronounce it Pukey.

[@wizrom3046]

That is a great project and a really useful bike! 👍 Throttle looks very harsh, like it is set to voltage control mode. If there is an option to set it to current control mode that will make it MUCH nicer it means your throttle will control torque like a combustion engine does. There might be a switch or jumper on the PCB to select that, I noticed you're good with the soldering iron. 🙂

Great Memories! ❤In the late 1980ies we tuned a two stroke Puch Maxi N to run about 8000 rpm (usually 4000 rpm)...that was a hell of a teenage ride and the Police didn't like it 😊

[@ba7134]

I want also want to build an electric moped: a Honda Hobbit/Camino (most sold moped in Belgium) with the batteries hidden in saddle bags in combination with a ape hanger handle bar for a chopper bike look.

[@JeremyMakesThings]

I’ve got a hobbit in the shed as well. Since the swing arm mounts to the motor, you could potentially mount the battery in place of the motor and do a hub motor 🤔

[@ShainAndrews]

Growing up means addressing the brakes prior to any testing commencing.

[@ulwur]

I have a (store bought) electric moped for my local commutes. Love it! One thing thats greatvwith it is that its quiet, it has a hub motor. So i suggest you replace that noisy chain with a silent belt!

[@dr.ozkalozsoy]

nice project. what is your motor? Do you have a link?

[@lumotroph]

Love your show. Bravo

[@michaelewan8009]

Using CAD I see (cardboard aided design). I cannot claim original thought on that, since it came from Bad Obsession Motor Sport.

[@guygillmore2970]

All hail the algorithm

[@kerrygleeson4409]

Great project thanks for sharing 🦘

[@Paul-FrancisB]

That brings back some memories, a Puch maxi was the first 2 stroke I stripped down and got running as a teen. I even sold it for a profit 👍

[@lomsen79]

I did not know puch maxi's were imported to the US. Thought it was only a european thing. We have lot's of them here in Denmark. But there's a hype about old mopeds, so they are crazy expensive. Nice project though. 👍

[@JeremyMakesThings]

There actually pretty common here (for 40-50 year old mopeds). We can pick them up for $2-300 (usually not running.)

[@lomsen79]

@@JeremyMakesThings That's crazy cheap compared with danish prices. 15000 dkk (2300 dollars) for a perfect restored Maxi is not uncommon. Other mopeds like the yamaha fs1, kreidler florett or the big puch mopeds are even more expensive. Like alot more. As I wrote, theres a hype about them.

[@TradeWorks_Construction]

Why did you need to isolate the headlight ground from the chassis? Is it because the 48v DC is high enough to pose a risk for accidental shock so the frame needs to be electrically isolated from the system? I feel like i’m missing something obvious with regard as to why it had to be isolated 😫

[@Tim_Kent]

At 23:44 it sounds like everything is isolated from the frame to make a short circuit less likely. 🤔

[@kendingsor]

I like the part where you stare at something and wiggle it back and forth.

[@sq3rjick]

You can get the least expensive A1 Mini from Bambu for $200 if you don't want to get too much into it. I've got the X1 Carbon (and have had it since pre-release) and it's been nothing but fantastic. Over 5000 print hours on it. I'm sure if you reached out to Bambu they'd come to some arrangement with you. Heck, probably the same thing with Prusa; don't think you can go wrong with either brand, and we've come a long way toward 3d printing being appliance-level.

[@ShittyTomsDEs]

He could really use the x1c for engineering materials. It's been so worth it.

[@PuchMaxi]

Did someone mention Puch Maxi?

[@PuchMaxi]

I see you need a rear fender.

[@crasbee]

23:12 Why on earth did they use the same plug for 110V and for the battery on the charger? That kind of plug is NOT meant for anything else than mains voltage. It's just waiting for a big fire to happen :(

[@JeremyMakesThings]

Yeah, I don’t like it. There’s actually a little notch on the charger plug, so there should be a little nub on the charge port to prevent that, but I’ll be damned if I could find a port like that. I’ll probably change it on the next iteration.

[@FliesLikeABrick]

​@@JeremyMakesThingssounds like the plug is IEC c15 so you would be looking for a c16 receptacle. Those are still standards for mains voltage, they are the same as c13/14 but the notch signifies higher temperature ratings. It sounds like you would be better off chopping the plug off the charger and replacing both sides with something more appropriate that won't get plugged into mains by accident

[@JeremyMakesThings]

@FliesLikeABrick what I’d really like to do is put an onboard charger and J1772 port on it so I can charge at normal EV charge stations, but like I said, future revisions. For now I’ll keep the key off when it’s not charging, and be careful plugging it in.

[@boherrmannsen8219]

if it where me (and its not) I would have modded the tail light to have 2 grounds to it

[@TheDistur]

"All I got's a moped"

[@martin-vv9lf]

would it be difficult to make a two wheel drive electric bike? i've seen mechanical versions and they're quite spendy.

[@JeremyMakesThings]

I’ve thought about it a bit. It would be needlessly a dual motor controller (so the motors are going the same speed), but those exist. There may be some issues with the fork not being designed to take that sort of force, but I guess the best way to find out would be to build one and see if it breaks.

[@criggie]

Is the moped practice for the JEEP ? (nudge)

[@JeremyMakesThings]

Basically, yes.

[@Rustinox]

Next project, converting an old Jeep in to electric... eh, wait...

[@chrislee7817]

Whoo hoo I wes number 999 like. Ducati contry. 👍

[@michaelfoster2563]

Put a relay to ground on the purple wire with the coil running off of the brake light

[@sethbracken]

Obligatory A frame house in the neighborhood. Made me laugh.

[@TheWoodyworker]

I am glad you and the van made it back.

[@BrainHurricanes]

Don't you love it when you're sure there is absolutely no reason something you put together shouldn't work and than it doesn't work 😏

[@Joel-st5uw]

Regarding 3D printing: Bambu hasn't figured anything out. Hard stop. All they've done is stuffed about $100 worth of hobby DIY convenience features into their printers and then stuffed a couple $million into marketing campaigns. If you want pro 3D prints, you need to buy pro gear, and Bambu is not that. Bambu is going to do more damage in the "false promises" department because printing noobs are buying them thinking it's idiot-proof. It's not. The people who rave about Bambu are people who ALREADY learned the hard way, but no longer have the interest or time to upgrade their existing printer boards/sensors/etc. Think of Bambu as the mini lathes of the 3D printing world: they're bringing an electric motor and tool holders to a hobby market that started out with pedals and hose clamps, but at the end of the day it's still mostly just a toy, and you still need to have the experience of material speeds/feeds/gotchas/etc to get anything useful out of it. Is a mini lathe better than a retro-fit DIY sewing machine lathe? Of course. Can you make production quality parts with it? Depends on what you need to make. Will you get production quality out of the box if you've never used a lathe before? Almost certainly not.

[@HeDzsz]

I happen to use both high dollar commercial printers an als multiple bambu x1c's. The bambu absolutely can be compared to far more expensive machines. We prefer to use the bambu for most jobs. Only using resin/inkjet based printers if the parts are too small or need fullcolor and rigid-flex combinations... In the office we nowadays have 4 bambus running non-stop. The pro machines we have include sls, sla, metal printer, fullcolor multi material inkjet. Etc.

[@Tishers]

"The broken promises of 3D printing" is still a thing. That is what is holding me off from making that sort of investment. Be real careful when using electric arc welding with cables that have loose ends; It is very easy to toast electronics with the coupling to high-impedance wiring.

[@mdalton3550]

Thought it was for your wife ? 🤣

[@hassmakki]

Love you channel and what you're doing. Keep up the great work. Thank you

[@jdmccorful]

Lots of interesting solutions. Cool! Thanks for your time.
