Even though he wasn’t in this video, Oscar did a great job.

Being a bike Mechanic for a good portion of my youth, I was dying watching the removal of parts. Makes you appreciate having the right tools for the job no matter a Car or a Bike.

Dang was thinking he was gonna take the drills apart and build a throttle with a variable resistor. But this is actually hilarious and still reversible.

Over 20 years as a bike mech. This is one of the most junky and hilarious videos I've seen in a while. Watching you bend that 22.2mm brake lever over a drop bar 😂😂

For anyone that was wondering, the official name for that brake cable is "Bowden cable". Named for Frank Bowden who owned the Raleigh Bicycle Company all the way back in 1902.

This was definitely worth the watch just for the pure entertainment of seeing Chris bang and thrash the bicycle apart without the inexpensive special tools.😂

you should buy 3 or 4 pedal go karts and do a similar thing but have a team wide build off. Do a few competitions like top speed, a slalom course, braking test, and then a time trial or parking lot head to head race. some could do electric conversions, others do like a lawn mower or string trimmer gas engine. that would be really cool to see.

Back in the day before they invented sportscars we built the sort of the same kind of bike, but we used a chainsaw... It went like stink, way too fast to be safe... Big fun!

I admit that it did better than I expected. The Hercules 1/2” high torque impact would do better. Especially if you can lockout the hammer mechanism.

one way sprocket clutch would allow you to retain the pedals... I love the concept and the diy nature of the build

I have gotten sick of seeing these e bike reviews. BUT, trust B is for build to actually turn one into a build. Great one. I’ll never look at my cordless drill the same way again😂 can’t wait for the next episode and build.

That Porsche in the back is not a spoiler at all :)

Keep pedals, mount 1 drill on each side of tire with a cable "clutch" to put pressure on/off tire when you need e-assist.

even tho this is a full on money grab video, its chris doing it, so I love it

I see a nice Porsche Easter egg lol hehe

That was a fun episode :) Wonder how it would have turned out if Oscar designed and made it. Head to Head.... next time :) Great job Chris, that was entertaining

Yes!! Pumped for a 911 build! Got my money on an offroad rally throwback.

The addmotor bike has a speed governor. 20mph is the top speed allowed by law for class 1 and 2 electric bikes. With a 750w motor it could probably do 40+mph with the governor removed

There are old mopeds that essentially used a drill motor with a rubber roller attachment that went directly against the outside of one of the tires and turned the wheel that way. Probably a lot simpler than this but I’m not sure which way would be more efficient.

This episode's build/review was just hilarious😂 The next review should have Oscar, he would've just build an e-bike.

This is one of my favorites. I don’t think I’ve chuckled so much watching a B is for build episode lol. Just fun, comedic and having a great time!

My first impression about using two drills is that you don't want them on the same wheel, as they will fight each other if not perfectly sync'd. I would have suggested put one on the front wheel, and one on the back.

You could use 2 drills and the pedals with one way clutching gears. When one drill cuts hit the other or pedal. I bet you could get some respectable speed out of it.

The thing I love about brushless drills is that over current feature. I've killed many brushed drills in my time even the best money can buy! Solid hack though Chris!

Finally, a Porsche 911. I’m so happy 😃.

Look at the gas powered bikes. Power it with a rubber wheel on top of the back wheel. There are some kits that bolt a sprocket on to the wheel itself. That way you Can still pedal it when the battery dies

“Taint destroyer” was great man haha!

Next iteration with a starter motor and some deep cycle 12v batteries… would be a cool Optima sponsored episode. In HS I worked at a boat shop and one of the techs had a 3-wheeler he electrified using a SeaDoo starter. The thing ripped around the yard as a parts runner.

Hey chris, if you did this a couple of months ago this bike could have been to SEMA

A larger drive sprocket would reduce the torque and perhaps it will be sufficient that the motor doesn't shut down. I thought you said you were going to weld foot pegs onto the bike. That would help. Also, you need a holder for your cell phone so you can track your speed without sacrificing one hand to do the filming.

Cool build. I was thinking, what if the original pedal sprocket (larger) was used on the rear, or maybe one larger than that? I'd think that would give the bike more torque and be easier on the drill, which probably has a lot more power to give (not that specific drill)

If you used a larger sprocket on the drill side, the gear ratio would be better.

Very informative Dr. Buildemall, I think more R&D is needed here. Which is probably what Admotor did. 😉

The most diy hacky bike power tool mod I've seen is where someone takes an angle grinder. Connects it to a bank of 18650's, and then sticks a rubber cylinder to the end of the grinder, and uses a lever to push the rubber into the wheel. It was genius for its simplicity on how to apply it to a bike. Because you didn't need to modify the gears, chain or main functionality of the bike.

I am a random watcher of this channel and wondering what I've got myself into watching Chris and electric bikes, Let's get going :)

As a former bicycle shop manager and an individual who used to build tall bikes, I would recommend using bicycle specific tools the next time you modify a bike.

So now... B is for BIKE!! hahaha

You probably could have made your first setup work by adding an adjustable chain guide to “push” the chain against the sprocket. That would also tension the chain and remove any wobble. I hope my suggestion makes sense, English isnt my best 😅

whats the actual drill setting though? I low key always forget 1 and 2. Ive worked with drills and power tools since i was 10

I laughed so much throughout this video. Great production.

This is how you make reviews fun On the drill, is there button to change the power mode? Maybe its on the wrong setting if it has multi mode choices? Just a thought since some of mine have adjustment modes even on my milwaukee 1/2 impact has some torque limiting modes or full send modes.

Couple of things: Between Black & Decker and Hart, neither of my drills in full torsion will just shut-off under load. Seeing Harbor Freight drills do this just teaches me to avoid them outright. The other thing is that I'm surprised you didn't do a bevel gear pair into a reduction to give them more torque and drive the crankshaft sprocket. You could've even done a mini differential to compensate for trigger variance and have both drills flush with the frame on opposite side of the bevel gearing. It's amusing to see that drill motors can indeed make the torque needed to make a bicycle go reasonably fast. With both, some throttle control, and at least a 7-speed shifter I feel those small battery packs could get maybe a mile or two of range.

I want to see a SEMA season where you partner with bike builders and you build your own electric cruiser for SEMA. B is for Bottom brackets!

I think a skill saw might have been a better option. Overall a fun episode, love the channel!

Did you by chance set the chuck(torque) speed to drill? And also the motor speed to the highest setting?

OMFG, that was absolutely hilarious😂 As a bike guy i was absolutely losing my sh!t watching you struggle with really easy tasks, and cutting the cc ranks off🤣 And your description of that POS ebike had me epically cringing, google Specialized Turbo Levo. And i can do 30mph+ on the flat on mine😉 And then there is Surron... I still love you though😉

We did something similar a few years ago (and by a few years I mean back when cameras on phones were not great). Our solution was to add a second large sprocket to the left side and then mounted the drill in the triangle of the frame (between the legs) and ran a second chain on the left side. We too ran into chain tension issues and put the drill on a slider and used a long bolt to get the tension. The only other difference was that we used a couple of motorcycle batteries as the 12V drill batteries (yeah, drill batteries were only 12V back then too) couldn't provide enough power for the torque.

So half way through best fu vid to any sponsor I've seen

Should have done it with an angle grinder or two. More torque and less slippage on the clutch

I got back onto a bike recently and yeah i can't remember the seats being so hard. Sore is an understatement i even got one of those "uncool" gel seat covers, and it does literally nothing to help. I now just drive everywhere again it's not worth the damage to that area.

What if you use the drill kinda like a chain tensioner so its always under pressure and would mske it harder to skip teeth?

Definitely a fun episode to watch.

Just a Porsche casually sat there in the background, accidental next build reveal?

Me the whole time: “PUT THE DRILL ON THE FRONT WHEEL & KEEP THE PEDAL FUNCTION OF THE BIKE & USE THE DRILL AS AN ASSIST”

Please make more of the videos. This is awesome

The Bisforbuild comment deletion and reputation protectionism is legendary.

Here's a tip for anybody with an electric bike. I have an electric trike (incredibly practical, I have hauled a load of more than 90 lbs of groceries) and I reduced my maintenance expense and time 90% by replacing the bicycle chain with #420 light motorcycle chain. You can't use the heavier duty #428 chain because the roller diameter is too large for the bicycle sprockets. A standard bicycle chain was never meant to handle the torque delivered by a 750 Watt (~1 HP) motor. I had that trike in the bike shop where I bought it about every 10 days, and they hated to see me coming.😀 It's been five or six months now on the motorcycle chain and nobody has laid a wrench on that trike since then.

If you relocate the trigger from the drill to the handle bars, and wire it to both drills, in parallel, it should run both drills at the same speed

One of my instructors at Wyotech told us when he was a kid, he and his dad built an electric bike using the starter motor from a car. From what he said it was insane while the battery lasted!

If the rear wheel already had a sprocket on both sides, why not run a second chain and save your pedals?

A note about the complaint of the 20mph max speed. In the US, that's the fastest an electric bike is allowed to go for "throttle assist only", known as Class 2. To go faster than that, you have to move to Class 3, where both pedaling and throttle are used. Those bikes have a max speed of 28mph. Anything higher than that will require a license.

Colin furze is not worrying after this video 😂

you can just get a bafang conversion kit and still have a usable bike. My mini dirt bike has a massive motor and 48v li-po battery that does about 30mph. Used a Razor mx650 as the base and swapped all the power train.

Last habit fright drill I got was less powerful than an rc car. Soo what to do it?

Been commuting by e bike for a few months now and I have been loving it (for the most part). Car insurance in my country is ridiculous and so are the terms for mortgages on first time buyers so I figured I'd switch for a couple years to save for a down payment. I bought a bike from Fafrees and it's a good thing it looks like a normal but beefy mountain bike because it tops out around 55km/h for me (after some rather light modification) and that makes it legally a moped in my country and I don't have my moped licence. (Transport is transport, if it has wheels and can be modified I'm happy)

now let's see Oscar's version of the drill powered bike and then a race each other

B is for Build, B is for Boat, now B is for Bike! Next year do we have B is for Blimp? I feel like just maybe... being airborne is a bit riskier with DIY.

Addmotor: "Can you review our products in exchange for keeping said product?" Chris: "Do you understand what we do here on this channel?" Addmotor: "......my question remains"

Nice Leader frame! I have an older version I rode for 8 years after college

It shuts off with a current limit so the brushes and commutator won’t get damaged. That function is in the switch and other circuit boards if it has other boards. Eliminating that would be difficult if it’s in the software like most modern cordless drills are.

Why don’t you put a tensioned release gear on the sprocket between it and the pedal? That way the pedal will be independent of the chain drive.

Very clever drill bike build. Fun video.

Why not start with a right angle cordless drill?

Colin Furze has some serious competition now

What if you had went from the rear sprocket over the top of the drill sprocket to the front. That would of given you more contact on it

Oscar knew what was coming and decided to leave town, most challenging build yet.

This was really entertaining!

At this point just change the channel to B is for Bike. This is obviously the peak of quality content and entertainment! XD

If you could change the setting of the drill while riding, that would be cool. Honestly, best would be taking the drill apart and giving it a custom housing.

Love the vibe of the video, dig the Timelapse track. What’s it called?

I'm slightly surprised that you did not (off-screen, of course!) take a look at the other bike to get some idea of how they actually did things from the start!

I have a much simpler design in mind, 99 sure would work and keep pedals. Pedal sproket will free wheel at speed if not pedaling on analog bike?

As the old saying goes “ don’t quit your day job”, you took a beautiful road bike and cobbled together an eyesore of a e-bike. I love your car builds though, maybe stay in your lane.😀

With a more upright position bike you would be more comfortable. Plus if you had a crankset with multiple sprockets you could remove the derailer and run a separate chain to the drill and that sprocket with better gear ratio. You could even retain a rear sprocket and derailer setup for less stress on the drill to get the bike going. Using a coaster sprocket on the drill head would enable you to run the 2 drills one would just overpower the other until wide open throttle was achieved and rpms matched.

Can we have some infos on the porsche 997.2 on the background ? Seems bit rough around the edges... Futur project (will love to follow) ?

ok this vlog was too funny. Chris, you looked out of your element?? 🤣🤣 back to da drawing board...Mahalo for sharing!!

Chris going all Colin Furze-y! Love it!

I'd love to see you pull the drill apart and make it as efficient as possible

on your reguar bike with classic tirangle frame..aliexpress has 2 stroke bike engines with an automatic clutch for 100 bucks. In my neighborhood.. my 1500w monster only has one eye to eye friend..an old two stroke ten speed custom built. I have had a blast with my electric. I am 50 yrs old..30 years no bike at all. go bigger than 1000w with all pedals.. all good.

Chris. You, Oscar and Kyle need to do a go kart build off, limit of like, $1500 each or something. Take one of those Tesla motors and put it on a go kart

I hope I see Chris riding around Portland with it 😂😂😂😂😂😂😂😂😂

Cable that rides inside a protective sheath is caled bowden cable 👍👍 so you dont have to call it brake cable

You were brave riding with i hand or a bit crazy well done for your effort.

Be pretty cool to have on the boat when making a trip.

Dope series!

A right angle drill for the win here

The distance between the teeth on the sprocket should be 12.7mm or 1/2 inch. All bike chains are halve an inch from pin to pin.

You could break the drill down and remove the control board and wire the battery direct to the motor it with a momentary on switch to operate the throttle but you would loose variable speed

you could’ve always tried two drills together with a somewhat abrasive cylinder in the middle on top of the tire in a U-shape then all you have to do is get some type of rheostat replace the two triggers with it. One drill, operates in, reverse the other drill, operation forward, and it uses friction against the tire to move.🤣 Oh yeah, the free wheel problem… you could use the hub from a rear wheel for the cylinder against the tire.

I am just waiting for a video on that 997 😍
