this is my first instructable so please point out any mistakes.

For this Instructable you will need the following materials

-a bicycle
-a cordless drill (any voltage will work but the bigger the better. I got mine from harbor freight for $15.)
-lots of zipties (how many you will use depends on your type of bike and/or drill)
-a piece of small wood ( this will support the drills' battery)
-a bicycle hand brake ( this is for the throttle system)
-bicycle cable ( this also for the throttle system and goes into the hand brake)
That's It!!!

Step 1: Adding the drill

Step 2: Ziptieing the drill down

Step 2

Now begin to ziptie the drill onto the bicycle frame. Make sure that the drills' chuck always stays on the side of the tire. Try to keep the drill in line with the tire. Get the drill as snug AS POSSIBLE against the side of the tire. The more friction you have the better the drill will grip the tire.

Step 3: Adding the throttle system

STEP 3

Combine the hand brake an the cable and the slide the hand brake on to the handlebars of the bicycle. This will probably require removing the handlebar grips. Finally, tighten down the hand brake.

Step 4: Attaching the throttle cable

Step 4

Beware this is the hardest part of the instructable. Take the bicycle cable and lead it down to the side of the drill where the trigger is. Ziptie the end of the black part of the cable to the SIDE of the drill. Wrap the metal part of the cable around the trigger and back to the side of the drill. Ziptie the black part of the cable and the end of the metal section of the cable together. Make sure that the cable does not pull on the trigger. It should only pull on it when you pull on the brake handle. You can skip this step and just pull the drills trigger with your hand. however you have to drive with one hand.

I like the idea of using the handbrake on the bicycle is awesome.

Super cool instructable. Like how you kept it pretty simple and straightforward. wish you had a few more pics from different directions (panned out maybe). Very cool, thanks for sharing!

Great! This 'ible proves that you can make efficient hacks with few things and simple ideas. Everybody should forget the word "cordless drill" and replace it by "cordless electric motor with chuck". Drill is just one usage among many...

Is the idea that the trigger on the drill will push the brake back out after you release? Because the spring in mine doesn't seem to be strong enough. Is there an easy way to replace the spring.

Check out killerjackalope's answer down below.
jackjackboom (author)  Bremer12812 years ago
That'sthe basic premise. I am sorry to say that I do not know how to replace the spring in your trigger. I would suggest buying a cheapo harbor frieght drill. I got mine for $15 with a coupon. That drill has lasted me through multiple projects including replacing drywall on our living room ceiling. I highly suggest getting one.
If you loosen the nut and the spring screw of the brake it should move back very easily...

Thanks!!!

again,to prove that drills mettle, i have attached it to one chain drive bicycle, a friction drive bicycle, a scooter, a lawn mower, i have used it to drill holes to put up a basketball goal, put together multiple wooden airplanes for my siblings, it has survived several drops, AND survived a torential downpour.
best use of $15 ever.

Nice!

I'm doing something similar (an 'ible is in the works, of course), using two of those exact same cheap HF drills, but with lawnmower wheels stuck to them... Here's the vid that got me going on that idea: http://www.youtube.com/watch?v=grcskPrbsvI

Mine will be completely removable (so I can pull it off the bike while I'm at work, for recharging & security), plus I'll be able to engage it on the fly so it's just power assist; can still coast and pedal. Only cost is $50 in drills and wheels, the rest is free, scavenged...
brutally cool!!
jackjackboom (author)  mcraghead2 years ago
That's so cool!
tell me when you get it posted!
Why not do sth so that when you pedal the battery gets charged? It would be even better like that!

The chuck would spin and over ride the motor and destroy it.
No Coasting either. Its what a person gets for taking 5 minutes to build something.

I almost made an electric drill powered little bike from some tiny E-Punk Razor bike. I saw a how-to -guide in Make Vol. 21 2010 magazine. The only thing that stopped me was the cost to get the parts. It required a powerful Bosch Lithium drill (about 36 V.) approx. $300., a right angle gear box that cost $115., an E-Punk Razor bike (used $150.) and a few other parts. It goes 0-10 mph in 2 seconds and supports an adult (230 lbs.). Its fast and can go two miles on one battery. You can see this little beast on pages 108-113 of the Make magazine Vol.21 2010. Awesome stuff in the mag., but this is too much money for me to spend on a whim as my other half stated. I bought the little E-Punk Razor bike. Actually two of them. One for part. I got a bigger 9" rear wheel, then the cost of the drill and the right angle gearbox stopped me in my tracks. If anyone can help me with finishing this in a cost effective way please get back to me. You were heading the right way with your project. This one is too costly for the average instructable . Thanks for sharing. As ever, Triumphman.

you could try getting a 1/2 horsepower electric motor from a broken garagedoor opener (free) and hook it up to a couple of motorcycle batteries or a car battery (about $50) Then get a PWN throttle controller ($50 or so), weld a bicycle cog or mount a broken drill's gearbox to the motor, connect a cog, mount motor onto bike ($20), link chain, put together PWN throttle controller circuit and you are done. For only about $120.
That would weigh too much!

It probably would

I never would of thought of this, but wouldn't weight affect the speed??

There is a link to the video on the intro now. Hooray!!!
did u ever think about putting a small generator and a wired drill that way it might go faster and u wouldnt have to worry about battery life?
jackjackboom (author)  zackattack243 years ago
I was thinking of doing that but with a car.It would be very cool.
