A Little Engine for a Bicycle from 1947 - Conservative Restoration
ฝัง
- เผยแพร่เมื่อ 9 พ.ค. 2024
- This engine was marketed after the Second World War to offer ordinary people the possibility of moving around, using it together with a simple bicycle. In the video, in addition to the restoration process, I will briefly delve into the history of these engines, illustrating the reasons for their birth and the context in which they emerged. While I will be restoring this engine, I will not be following a total restoration approach; rather, I will adopt a conservative method that will preserve its' lived-in appearance. The video will end with the completion of the engine restoration, while the second part will focus on its assembly on the bicycle and the related tests

What a lovely little motor. What a treat to see a real mechanic fitting new bearings without a hammer
Gotta do what you gotta do
That was classy!
what a beautiful little engine - why can't they still be made like this today. You have to admire the engineers who designed this in the first place - truly incredible.
Corporate greed and tight emissions requirements
Emissions is one of the biggest reasons. This thing is a 2 stroke which means three things: an absurd power to weight ratio, mechanical simplicity, and pretty lousy emissions. You just can't make an EFI four stroke (mandatory for modern emissions controls) that matches it for simplicity and lightness.
7:27 what a very clever way to remove bearings from a blind hole
Thank you!❤️
I have also seen slightly dampened bread used for that as well.
bread also works for this, watch out though, you can punch a hole through the engine case
Yes even bread works well, I tried that too
grease is the more accepted way. you wrap more or less electrical tape around the thread of the bolt to improve the seal.
What a beautiful engine with an ingenious 3-speed gearbox!
It is very special that people made such beautiful things at that time.
Very good film of the restoration!
Thank you! ❤️
AND it's 1947 ! So ahead of its time.
As Italian i can say only one thing : BRAVO !!!
Speaking of Italian build quality, I bet that little motor will outlast 100 of those China 80cc bicycle motors they sell online today. Italians make some fine engines. Minarelli motor in my rough house moped is the strongest 50cc there ever was unmodded.
My God, this is the coolest thing I've ever seen. I had NO IDEA these mods were available when Roswell happened. How ahead of their time. 60cc on a bicycle is INSANELY fast !!!! I would've given up 1982 Christmas to have one of these !!!
I would love to see it fitted to a bicycle of the same time period!
cheers from Canada 🇨🇦
I’ll mount the engine on the bike that you see on the video thumbnail 😉
7:27 that is GENIUS
Коробка передач с шариковой фиксацией - это, конечно, гениально. Нигде ничего подобного на современной технике не видел. Подозреваю, что из-за ограниченности передаваемого крутящего момента, а также из-за развития традиционного вилочного механизма с бронзовымм синхронизаторами. Однако по меркам 40-х годов, когда даже на машинах обычным делом была КПП на 3 передачи без синхронизации, которая требовала двойной выжим сцепления для плавного переключения без рычания и хруста, вот такой компактный механизм 3-ступенчатой КПП был действительно гениальным решением. Ведь, из-за отсутствия угловатых элементов (таких как шлицы для зацепления шестерни с валом) передачи должны включаться мягко, а для их смены не нужно даже нажимать сцепление. Плюс, управление с помощью всего одного штока, расположенного внутри вторичного вала, делает весь механизм компактным.
Откуда там взяться "мягкости" включения)?Если не угадал,будет тот же хруст.единственный плюс таких механизмов-компактность.Слабенькая схема.А чтоб КПП прощала хоть как-то грубое включение тут уже нужен демпфер на сцеплении.А здесь дальше скорее всего была ременная передача,и могла работать,как сцепление.Увидим в продолжении,что там и как.
@@kotborka именно хруста в таком механизме в принципе не будет, потому что хруст - это когда шлицы вала и шестерни друг по другу скачут, но не могут зацепиться. А тут нет шлицов, потому что вместо них шары. Если механизм слишком быстро крутится в момент переключения - на переключателе (ножка там или рукоятка - хз) просто будет ощущаться сопротивление до того момента, как скорость вращения достаточно снизится, чтобы шток продвинулся и затолкал шар в пазы.
@@nz3230 Ага)),просто другой звук будет,хруст помягче)).Когда ты пытаешься затолкать шарики в выемки в шестернях)).Это ж металл,епта.
@@kotborka хруста там не будет в принципе. Потому что хруст - это когда угловатые детали скачут друг по другу. А шары круглые, выемки тоже. Я не пробовал такую трансмиссию, но опыт подсказывает, что при переключении передач на повышенных оборотах будет просто изменение тональности звука, до снижения до приемлемой скорости вращения. Это какая-то секунда, что не сравнить с хрустом вилочного механизма, который при спонтанном переключении без сцепления (да, я пробовал - на той же ВАЗ 2109 переключаться так можно, но при тонком подходе) может звучать несколько секунд и сопровождаться скруглением шлицов, которое вскоре приведет к выбиванию передачи.
@@nz3230 Молодой ещё,зеленый))!Шарики хоть и круглые,но пока не зайдут в зацепление,удары неизбежны,и будет это чем-то похоже на отбойный молоток или дрель с ударом,если включать грубо без сцепления.Да,можно и без сцепления тихо переключаться,особенно вверх,на разгоне.Но во-первых,нужна кулачковая коробка,чтоб были хорошие зазоры между кулачков,чтоб передачу можно было втыкать при некоторой разнице в скорости шестерен,нужен демпфер в сцеплении,чтоб сглаживать неизбежные удары,и кпп авто с их шлицевыми муфтами ,сидящими на шлицах почти без зазора практически не подходят для этого.А вот на мотоциклах вполне можно ездить без сцепления,или почти без.На разгоне даже газ обычно не сбрасывается,только чуть выжимается сцепление и передача сама входит).На снижении скорости приходится играть с перегазовками,иначе не включишь.Но можно.Так что хоть округло,хоть угловатое,но это железо)),удары неизбежны.
I like the blued/blacked fasteners, excellent touch. Not buffed, thank God.
Vélo électrique :non merci
Ancêtre du vélomoteur (moped) oui
Ancêtre de la moto oui
Très beau travail de restoration
Thank you!
разобрал-очистил-собрал. шедевр!
Lovely! Very much looking forward to the next part too!
Stay tuned!
Dans mon enfance, juste après la guerre, il y avait plein de petits constructeurs de moteurs pour vélos, qui utilisaient un galet pour entraîner un pneu par frottement.
A 12 ans, en 1960, j'avais ainsi fait un petit tour sur le vélo motorisé du père d'un copain de mon âge, avec un moteur Garelli.
On était loin du vélo à moteur des frères Werner de 1898, dont un seul est encore en état de rouler et que j'ai eu le plaisir de voir tourner en 1986 sur le circuit du Bois-Guyon à Dreux.
Salut et fraternité*
Bearing in a blind hole, nice trick. Ta.
Touched it only when nessasary 👊
Beautiful 🧚
Thank you!
Wow, great work! I kept being impressed by one specialized tool after another.
Restauro minuzioso su tutti i particolari meccanici ! Appassionante !
Complimenti !!!
Thank you!
3 speeds but no clutch, what a peculiar design
Thank you for not ruining the engine by filling it with paint, you are a restoration hero!
Ahaha Thank you!
I´m impressed. Did not intend to watch the whole video, but I did. Very well edited. Those grease-shot alone are awesome 🙂
Thank you! I wanted to make it shorter but didn’t know more than part remove 😅
A classic engine restoration complete well done
Thank you!
Saludos desde España...has realizado un trabajo exquisito con esta restauración...desmontando hasta el último tornillo para dejaro todo casi en estado de fabrica...He pasado un rato entretenido observando como realizabas todo el proceso de restauración...Ahora solo queda verlo montado en una bicicleta y funcionando....
Thank you for the compliments! in the continuous of this video I will make a conservative restoration also on the bicycle and I will mount the engine to try it etc
Very Cool, Weird looking piston I like it, an that Trick with the wet paper towel to get the inner bearing is Brilliant 👽👍🏻✨
Thank you! That shape of the piston is called a deflector, helps the escape of the combusted mixture and was used on the old two-stroke engines, where a lot of oil was used in the mixture because the oil at that time was of poor quality so you had to use more to get a good lubrication. This engine uses a mixture with 8% oil (in a liter of gasoline should be added 80ml of oil!)
you can also use bread for bearings like that
@@11sjv 👽👍✨
Yes I tried that too and it works very well
I am impressed with your skill and even more with your attention to detail, most impressed ... thank you for sharing your enthusiasm for restoring these older machines ...
Thank you! ❤️
I love the cake icing grease spooge application the best
Great close up shots in video! I like how you showed the process of restoring the parts, and I'm surprised that instead of oil , grease was used in the engine.
Thank you! Grease was used because oil seals had not yet been invented. In fact, the fat being more viscous than oil makes it more difficult to get out of the holes. If you see the point where I take the breaker contact plate off, below it is a kind of brass washer and a felt pad, not an oil seal, just because they didn’t exist yet
@@Ego.Reficioneat
I can just imagine in the repair manual, it saying- use a liberal amount of grease 😅.
Μπραβο φιλε πολλη ωραιο το βιντεο. Καλη συνεχεια σε οτι κανεις.Χαιρετισμους απο ΕΛΛΑΔΑ.
Thank you!
Es un hermoso motor , pequeño y sorprendente con 3 marchas , una maravilla
Nice little moped. Looks like you're plagued by those mud budgies ( wasps) as we are downunda. I hate the little buggers. 😅
Thank you! For the moment I have found only those nests. Perhaps because the engine was for several years on that shelf and the place where it is located is very hot in summer
Ah, sweet memories of childhood. I remember mounting such one on a Mishutka children bike, so my mom would allow me to store it in our small apartment, because the motorbike would be too big to fit in the elevator. Technically, you could wheelie it in, if it weren't for the exhaust...
Ended up renting a garage.
❤️
Isso sim é uma restauração de qualidade!! Like e inscrito do Brasil
Thank you!
Отмыть главно, это самое сложное и время всего больше на это уходит зато сборка качественная получится и собирать приятно и все мелкие дефекты видно
that yelly insid was better than any cosmo! 😁👍cool! it surely conserved it well!
Flat head screws! Oh the joy of simplicity. Primitive but effective and accessible.
this man loves his grease
Nice to see a restoration done with some finesse rather than a vapour blaster.
Actually the grease doesn't look too bad at all! lovely Motor! That must be the smallest Valve I've ever seen 🤓
Well done & Thanks for showing!
Probably, but once disassembled everything seemed right to change it
Came for the build, stayed for the lore
Отличная работа отличная реставрация 👍👍👍👌 хотелось бы услышать звук мотора.
Beautiful restoration build Sir, you are a Master with lots of patience, subscribed and thumbs up, thankyou for your time
Thank you instead for watching the video and for the subscription!
Всё шикарно сделано, за исключением одного момента! Нельзя класть столько смазки! То же самое- попробуйте наложить под завязку, в редуктор угло шлифовальной машины! Это приведёт к перегреву и повышенному износу ! Но в этом видео, главное «лайки», а не грамотность сборки!
You can’t see it clearly from the video, but there are a lot of empty spaces in the crankcase that are not occupied by grease. Also consider that during operation the grease will tend to melt and this will leave even more space
Ну,ты сравнил).Этот тихоходный агрегат и не заметит полный редуктор,зато все будет хорошо смазано.
@@Ego.Reficio Жаль,что по сути уплотнений нет и нельзя залить жидкое масло.Хотя если постараться,то можно крышки доработать и установить современные резиновые самоподжимные манжеты и заливать обычное масло.
@@kotborka Эксперт!
Yes, by changing the crankcases and using the oil seals, you could safely use the oil
What is the purpose of filling the engine compartments with grease?
Great video thanks.
I did this because the gears need to be lubricated, and because the engine doesn’t mount the oil seals yet, the oil can’t be used
@@Ego.Reficiomy grandpa said dont feel bearings and gears more than 1/3 with grease to let mechanisms go freely...
From the video, it's not very clear, but in the engine casing, there are many empty spaces not occupied by grease. Also, consider that with heat, the grease tends to become liquid and leaves even more space
Excellent work
7:29 perfect
Even got a Magneti Marelli spark plug.👍
I'm surprised he managed to find replacement bugs for the exhaust pipe.
-Really nice rebuild! ❤
Thank you! ❤
SPLENDID MAESTRO
Fabulous restoration 👍👍👍
Сколько лет он хранится так в сарае что это за коричневое дерьмо которое надо было счистить -это осиные гнезда?
Когда этот двигатель выпускали?
Он заводится или нет?
@user-qs6ov5nl3q The engine was purchased 10 years ago. It’s been on the shelf for 8/9 years. The brown one is a wasp nest
The engine was produced in about 1947
Very good work,and amazing engine,greetings from Greece
Thank you!
Which degreaser do you use? Seems to work perfectly!
I use Chanteclair
This asmr very cool,,, clean engine
Thank you!❤️
Hmm, a ball-lock gearbox. Interesting. They are not used anymore AFAIK, the last motorcycle manufacturer to use ball shifters was Hodaka.
Very nice video, Very good workmanship!!! Good Job.
Thank you ❤
Awesome
Thank you!
Bravo
Buen trabajo de restauración felicidades, pregunta en ves de grasa no serua mejor aceite? Y cuantos cambios tiene? Aunque no le veo el clutch embrague
Thank you. The oil cannot be used because the engine has no oil seals, so the oil would come out. The gearbox has 3 speeds, but does not use the clutch. To change gear, you have to decelerate and engage it gently
@@Ego.Reficio Gracias 👍 excelente.
Buen trabajo!!👍👌😍
Thank you!
Now THAT was a well-made video. And a nice little engine. Seems to be not your first rebuild. Nice.
Thank you! You’re right, it’s not my first rebuild. I’ve been enjoying restoring small engines and more for several years now, it’s just lately that I’ve decided to make videos to show them
@@Ego.Reficio I am really interested to see the finished product. That valve and actuator on the head intrigue me...
Stay tuned!
Поршень тоже интересный как и двигатель
Awesome. For those who don't know this they actually still produce bicycle motor kits to this day. Basically a similar design but just made in china. They can work great, last a while, costs $100 or less on average for an entire kit too
Yes, in China they make a kit with engine, tank etc. I've never tried one but it doesn't seem like a quality product to me
@@Ego.Reficio They work, they can last if you take care of them but it’s definitely a low quality product. Just need extra work
my comment is somewhat different, for the time period this engine is a well engineered piece of equipment.
simple yet efficient, we always thought Italian stuff was cheap trashy and nasty. now as an old man I look at this engine with different eyes.
Italian's did really well with what they had after the war, hats off to them.
Cool engine
Мастер своего дела !
Thank you!
👍👍👍
With these no driver's license is required in some states. Here in the state of Kansas still legal and no license is required
Very great restoration, love the method to Remove the bearings in a blind hole, can you please Tell my what gasket adesive did you used?
Thank you! I used an old spray that I have already for several years, probably is not produced more of the same type. The spray is Loctite, NO.99 High Tack Spray-a-Gasket
@@Ego.Reficio thanks!
I always have the thought now and then when i watch mechanical things how impressed archimedes and da Vinci would be with the stuff we have today, they were right on the cusp of discovering these dynamics if only they wouldve had machining tool and die equipment how much farther we would be along now. Likely ww3 would come just that much sooner.😂
Start it up! Start it up!
In the next video 😉
Great job. Shame couldn't see it running
In the next video you will see😉
excellente
❤
👍 👏
È proprio un bel canale, grazie.meglio quei tempi che quelli odierni, secondo il mio punto di vista.voi che ne pensate?!
Thank you! I think they were very different from our times. For some things they were better for others not. Surely they were a fascinating time
Creative video, thanks :)
The fundamental thing was forgotten: Show it in operation.
In a next video I will put it into operation because this video is released very long. In the next video I will restore the bike, the tank and the crown, and of course I will mount everything to try it
U didn't start it😭
I will start it into other video, otherwise this would have become too long and no one would have seen the restoration, but only the start 😂
Cool motor
The inside is clean thanks to the large amount of grease.
Cheesehead screws. You never see them anymore.
My wife and I have these on our bikes and ride them all over place.
Do you have the same kind of engine?
@@Ego.Reficio No, I should have specified that in my original post. We use the recycled beer can ones from China. They are very similar but the quality isn’t even close. They aren’t bad once you now what to address when you get them.
I understand. I’ve never had one of those made in China, but I think they’re still fun to use. How do you solve the problem of having the license plate and the insurance, in order to move on the street?
@@Ego.Reficio in my state( Ma. ) As long as the engine is under 50 cc, it’s considered a moped and doesn’t require registration or insurance. My engine is 66 cc but I have a sticker that says otherwise. They really are super fun and much cheaper than electric. Well, for now at least.
Great, so you can use it without problems!
How come that stuff is still in near-pristine state after all those years? What was that engine made of? Some extra-terrestrial metal?
What do you mean, "stuff"?
TP as a hydraulic fluid. 🤯
my first fear when seeing an old engine is those ducking asbesto parts in all kind of electric installations or gaskets...i grew up with that shit and now even on some new engines from Asia or somewhere we can,t be sure our brand new ones dont, have any Asbestos gaskets...
and my sexond thought is always, as i started to stufy some engine stuff long ago comparing old and new biat engines and lateron airpkane installations for small himebuilts( which were actually high tech 80 yrs ago) ...and when you compare consumption bice HP : NOTHING HAS EVER CHANGED ! we could have spared endless " developement" bcs it has brought noth8ng but extremely high waste of resources...and costs...
the old engines basically used as much fuel as new ones, the well made ones off course...were fucking cheap , easy to repair , burnt every chunk you could dind to fill in and servde the purpose....you all get what i mean, yes! tannks for showing!
I can never understand this american paranoia about asbest. Yes, it is cancerogenic but gloves and simple masc protect you 99%
Крутой моторчик! У нас в ссср в 50е производились веломоторы серии "Д" и"Иртыш". У меня в колекции 5 двигателей серии "д" разных годов выпуска. У нас их называли " дырчик", "дешка" или "газуля".
Interesting! I did not know about the existence of these engines. Congratulations on the collection
@@Ego.Reficio Эти двигатели популярные и до сих пор как совецкие двигатели д4-д5-д6-д8 так и китайские аналоги этих двигателей под названием F-80 F-50
Very interesting, I wasn’t aware!
Но у дэшки передача только одна, а тут - целых 3. Вообще, очень интересный движок, который сочетает прогрессивные черты с архаичными. С одной стороны, у него интереснейшая трансмиссия с шариковым включением передач. Для эпохи, когда не синхронизированная 3-ступка, требующая двойного выжима при переключении передач, была обыденным делом на авто - такой механизм на мопеде был гениальным решением. А вот с другой - моторчик без сальников, с солидолом вместо жидкого масла, и прочая архаика.
motore spettacolare io li collezione e ho 10 di questi motori di varie marche sono motori che danno soddisfazione quando me restauri e li metti in strada sono curioso di sentirlo acceso
What engines do you have? I also have a mosquito, a siata cucciolo and a cansa cucciolo. Maybe on the cansa cucciolo I’ll make a video in the future
@@Ego.Reficio ho il mosquito 38 a il mosquito 38b targhetta blu mosquito BMG prodotto a napoli ho l'alpino due marce secondo serie itom tourist il jolly nasetti pellegrino super aquilotto bianchi modello oropa due marce
Congratulations, nice collection! Did you think to add a Cucciolo to the collection? My favorite, but that I never found is the Asso engine
@@Ego.Reficio honestly the puppy doesn't drive me crazy also because the prices of this engine are crazy I had the ace engine in my hands then because of bad times I sold it are you Italian?
Si sono italiano, rispondi in inglese per rendere i commenti leggibili da più persone. Si il prezzo del cucciolo è sempre molto elevato. Peccato per l'Asso
Bushing top end = decent oil amount to avoid undue wear.
very nice , i wonder how it sound
stay tuned
Никогда не видел ещё герметик такого цвета),да ещё такого приятного).
А что за моторчик,какой рабочий объём хотя бы?
It’s a sealant for flat surfaces. The motor is 60cc
WHAT TYPE OF GREASE USED?
It is a low viscosity gear grease
👏👏👏👏👏🇮🇹
Такой маленький двигатель и при этом трехскоростной! И это 1947 год. Советским дырчикам 70-х...90-х годов до этого итальянца далеко. Так же как и выпускающимся сейчас в Китае аналогам советских д-8.

I’ll make another video where I’ll do a quick conservative restoration of the bike. I’ll mount the engine and test it.
The video will be released in early summer
очень интересно как устроена коробка передач.там 3 передачи?
Yes, the gearbox is three-speed and there is no clutch
@@Ego.Reficioможете в дальнейшем показать подробно устройство и работу коробки передач?
The operation is very simple, there is that rod that when it is pulled or pushed out three balls on the selector and meshes the gear you choose to use. As for the lack of friction, however, when the engine is running, you decelerate and change the gear. The large crown that you see at the beginning of the video, must be mounted on the rear wheel and inside there are springs
@@Ego.Reficioбольшое спасибо.хотел сделать подобную коробку передач на 2 передачи,но не справился
Of nothing. Good Luck!
0:06 is that larvae???
Yes, they are wasp laverve
Who owns the patent now ? Would be nice to put it back into production . 3 spd tyranny is nice option.
I don’t know why the company that produced it hasn’t existed for many years. It would be difficult to put it back in production since we are going to meet the electric. Consider that this engine uses a mixture of gasoline and 8% oil (in 1 liter of gasoline should be added 80ml of oil)
