We build a 100cc Motorbeast! 

Beautiful frame, Great New Re-Done YD100 Great build w/disc front and rear, A very highly sought after setup for all to buy! It has taken some years now for it to be done right but finally a Real Setup can now be purchased, Great Video As Always Alex 👍

Love the brapp cage. I just got the gold rear gas tank today and I’m ordering the gold pipe to match. They have improved the spoke wheels I’m so happy with mine.

Just picked up that motor. It looks good, and I can't wait to get it on a bike! Thanks for the build plus ride, brother! Good work! 👍 ❤❤

I dig these kinds of videos

In the South we call those pipes leg burners. Why put it there where you are destined to get burned?

Gold tape the outside edge of wheel rims be the finishing touch.

Nice bike! Just love your truing “stand”! So simple!

Always nice to see you post

Beautiful build!! A+ love the gas tank.

Just starting out in motor bikes my 1st absolutely awesome on my second, thanks for the old forks truing set up, great idea & free, & I have all the materials 😂

I put a Predator 212 in my Giant frame, Honda 10 amp charging coils, a 7" Harley led headlight, bullet style led tail light with brake and turn signals, 14" riser bars, Rock Shock front end, with 4 piston hyd brake. Comet 30 trans, and a 6 spoke mag wheel in the back, with 2 canvas saddlebags slung over the back rest. A 2 gal gas tank sits on the crossbar, With some flowing, jetting, big air, and smooth exhaust, the engine produces about 10 or 12 hp, which gets me over 70 mph, but I keep the throttle stop screw set at 80 kph, which keeps the rpm's under 5,000. I can pick up the front wheel almost effortlessly from a stop, and it rides like my old 76 shovel head Harley. If you want a more serious ride, I highly recommend the Monster 90, 78.5cc 4 stroke engine, using a Comet 20 trans, and Go Power Sports Juggernaut clutch. You won't need to modify the frame to fit the Monster engine, but you do if you use the Predator. These engines will outlast those China Doll 2 strokes, 10 times, or more. I've been riding mine over 7 years, and it runs like new. I think it will probably outlast me, as I'm 70, blind, and deaf. Wish me luck.

Hey Alex from the czech republic. I purchased the 100 max cylinder to upgrade my yd100 to a 2 piece. Cool cool bike man

The little edge on the tape is going to shredd your shock seals

Hey Alex you should do the gas cap and gold.

Alex send me that frame to Portugal! beautiful bike buddy

Nice ride Alex

What's up love watching you build bikes I am wanting to build me one I'm from bogalusa Louisiana

Love the blue and gold color combo looks great…

What an awsome bike bro. Looks real nice. Sounds good too.

Wax on,wax off Gas on,gas off

I own Schwartz 15 speed limits bicycle I purchased from Walmart 25 years ago

Love the bump start! Takes me back

You are awesome!!

Volume level all over the place! Nice looking bike!

built 2 motorized bikes, FUN to build! But rear bearings gave out even when I packed them with grease

that bike is sweet . nice color combo .👍

Awesome built my friend!!

Do you guys recommend using an expansion chamber during break in? Is there any harm in the longevity of the engine?

Looks great. Just one thing, take off those silly reflectors on the rims. Would look cooler without them. Bike sounded great too. I'm going to smash the like button.

Nice build good to see you still at it been around building these bikes since 09

Sounds so much better than any motor bicycle I've herd.

I’m working in my shop now and listening to you building your bike while I’m working on a $200.00 budget motorized bike

I didn't see the wheel set do they come with the frame?

Love the truing stand! Thanks for the idea!

Nice builds bro, u help me out a lot with your vids, keep it going bro 👍👍, I got the varka scooter cause of your vid on it, that thing is fast, did not even get to 3rd gear yet, lol 😅😅,

Hi Alex, very nice bike! You know what would give the bike that extra special something... Paint a long, horizontal, tear drop shape, gold colored decal or stripe along both sides of the blue colored gas tank. Start with the round part of the tear drop shape at the front part of the tank...👍

this looks cool

Kickstand with the gold tape and forks are impressive.

I cant wait! Watching this in anticipation of my brapmobile .( Its adam from PA)

Se ve muy bien! Pero en realidad es un dolor de cabeza! Vas a estar más tiempo arreglando todo los tornillos que se afloja con la vibración del motor que manejando!

Very nice colors. Great bike. Please tell me how did you filmed it? Some special bracket? I would like to film my ride too

While I love your "mods,and builds",I asked for all of us who can barely add to our bikes>Look at my next post here.We can't spend $5-600 for a frame.We have a bike,like You started with.Please remember us and Do videoes for Us too.TY.

I'm also Working on a good handful bikes modifying them

Which of the 3 engines would you suggest for long term use? Zada 80, Phantom 85, or the new Zada100 max? I'm 155lbs, travel 38 miles round trip at 24mph once or twice a week pulling a trailer to haul groceries, water, propane, gas with a couple small hills, about 400ft long. Presently running a BBR Stage 4 with a MZ 65 clone and OZ reed valve. Thinking l want a bit more torque to run a 36t and still maintain 25mph. What would suggest? My bike is a GX7 Genesis 29r

That gold pipe nice the frame paint that blue killer

Whats up guy I have the same engine I can't get it to idle

Beautiful bike Alex! You know how to Build them Crispy 😊... Awesome 👍

Happy to subscribe

A yd 100 has plenty of power stock

how fast will that 100c engine go?

that frame is electric colorwise anyone who couldn't see it shouldn't be driving

That's going to look Great

Alex? The alex that helped me out sooo much with the mags?

best thing ive done is get a $180 rockshox 30 Silver TK and a $80 SR Suntour SP12 NCX seat post . i run my cables/wiring in expandable cable sleeves and use a $13 bmx hallow stem bolt to run the front brake cable threw the stem . clone vm18 mikuni carburetor with a k&n type filter is a must have to get those motors tuned right and nice

U should put a jackshaft with a derailleur on it

Nice 👍 build.. I built a few 2ts had my custom redone phatmoto 4t for a few years but now if I'm going to push the legal limits of what is a bicycle I'm sticking with my sur-ron LBX all that noise I forgot how loud these things are lol I have the 125cc 2t power on a silent platform that I can wheelie and jump 🦘❤ and so far almost 5,000 miles and cops leave me alone for the must part been pulled for rolling a stop sign changing lanes without a signal but nothing was said about the bike itself.

That tape is gonna kill the seals on the forks

Nice bike,I have one very similar

Looks very cool, hut that 2 stroke corn popper sound drives me nuts... a 4 stroke would be very nice....

Bueatiful! Sound great.

Bad ass bike bro.

I would definitely use an offset intake or use some heat wrap on the pipe as the pipe being that close to the fuel line would make me nervous. And cold fuel makes more power.

How’s the vibration on this thing?

💯👍👍👍👍 it wood be better if you added a pull start on the engine kit

Love from ireland

The triple fork tube does not line up in the top.and need up a little the gas

good job 👍👍👍👍 from ja

Can you do a SICK Phantom build?

Did you think about MCU-powered ignition system, like for example Sparkduino?

That gas line is dangerously close to the exhaust. You need an offset intake

Yo bro what size is your rim and your fork is it 26ER?

From Somerset KY

I’m looking to buy this exact one on your website! Can you get it delivered assembled?

Dam your first ride kinda discouraged me from trying something other than my 4 stroke builds.

Is it possible to add ape hangers ??

I like the way the bike is made but you want to fast thrue the way that you did so it should have been done in 2-3 segments other than that fantastic bike.

Beast? Bmb.

Wondering if it's possible to put a 100cc motor on a Himiway Zebra ebike?

i love this projects , why not a 49cc? more cheap and silence? or 4 stroke motor for garden motor?

Looks very good except for that chain too tight we're out the bearing on the engine and the will. And it's geared for 120 mph😊

I'm interested in building something like this but using a predator 212cc motor and like doing away with the pedal cranks are just having pegs any advice

I find the engines that have those 6 dots on the bore tend to be the best engines.

Hi you seem knowledgeable about this if I have any questions can I ask you questions

I've been seriously looking at that bike but how are the forks are they strong??

When you parked it at the end, it looks like it has a 26" wheel on back, and a 20" or 24" wheel on the front?? Is that how its set up??

Hey alex how fast should I run a yd 100 100cc during break in because it at a slow speed it jurky.

I'm from Goderich Ontario

I wanted to see the assembly of the forks with the steering... And they always jump past that. I think I'm missing parts

From North Carolina does that max 100 have 10mm or 12mm pin

Turn it into a trike and hopefully had a Honda a Honda 125 or 110cc or a smaller scooter engine like from Honda ruckus Or Honda zoomer engine

What frame is that m8 , I'm stuck in blighty,,, just asking ta

Cool ❤❤❤

I have a Schwinn stingray I've been wanting to go motorized with just can't decide what engine size to go with

Just imagine the power on this frame if the engine was 2stroke 🤠

How did the gold color hold up on the exhaust ?

You wrecked your forks

The only thing I would do differently than you is add a heat shield to the carby and add a muffler and risers beautiful build mate 👌

I think this will be my next build. Are the frames on Amazon any good?

What the size of the frame

I just ordered the same bike , I was wondering what size handlebars can I use , I want bmx or ape hangers do you have Any links for other handlebars that will fit this stem?
