Introduction: Super Simple Electric Scooter!!

Picture of Super Simple Electric Scooter!!

Yes, today we build a friction drive electric scooter that is powered by an 18 volt cordless drill!!

Personal Story: My parents wouldn't let me buy my own electric scooter, so I built one out of stuff we had around the house.

P.S. Keep Dad happy.  Buy your own cheapo cordless drill at Harbor Freight and don't use his!!

Okay, onto the parts list.
> A cordless drill (the bigger the better)
>A simple push scooter
>A piece of stick-on velcro (you will use the scratchy side only. If you can get it use rubber tape.)
>A rectangular piece of wood or plastic (this will support the drill)
>A whole lot of zipties 
>A bicycle hand brake and cable (for the throttle)

Here is a link to a video of the scooter in action.

Step 1: Remove the Brake Pedal

Step 1: Removing the only safety system on a razor scooter, the brake!!

My scooter had a small pin on the brake assembly that I hammered out with a small bolt and a hammer.
Your scooter may have a bolt and nut or something like that and it shouldn't be that hard to remove.

Before posting this, I tried to make the scooter with the brake pedal still on. It presented many challenges, so I removed the stubborn thing. Removing it made everything easier.
After you have done this you can move onto the next step.

Step 2: Add Friction to Your Drill

Step 2: Adding velcro to your drill's chuck

Okay, now you need to add something to your drill's chuck to increase its friction against the scooter wheel.
I used the scratchy side of stick-on velcro.This worked for me but you could use anything that will increase the friction between the drill and the wheel. Now you need to wrap the velcro around the chuck. Easy-Peasy-Lemon-Squeezy.
Also, make sure that the chuck still spins.

Step 3: Add the Drill Platform

Step 3: Now it is time to add the rectangular piece of something mentioned in the parts list.

I used a piece of plastic that came with a science kit. You can use a piece of plywood with holes drilled in it, if you can't find something similar to what I used. Position the platform at the rear of the scooter with part of it hanging off the left side of the scooter .To mount it, take a ziptie and thread it through one of the holes that the brake pin went through. Now, tie the platform down with the zipties. If you can't do this, then thread some zipties under the bottom of the scooter and up through holes in the corners and middle of your platform.

Step 4: Tie the Drill Down

Step 5: Adding the drill
Position the drill at an angled position so that the chuck is touching the wheel at an angle.
Begin to ziptie the drill onto the scooter. Be sure that the drill retains it position on the scooter.
Position some zipties so that they pull the drill into the wheel. This will increase the friction and thus speed.
You can test how tight your drill is against the wheel by pulling them apart softly. The bigger the gap the tighter your zipties need to be.
If your drill is tight against the wheel and not slipping off the scooter you can go onto the next step.

Step 5: Adding the Throttle

Step 5: Adding the throttle

To add the throttle you need the hand brake and cable. Start, by putting the hand brake on the handlebars.
This is simple, all you need to do is remove the hand grip (I didn't have any), slide the hand brake onto the handlebar, tighten it down, and put the grip back on. Now, lead the brake cable down to the drill and position it right behind the drills trigger. Ziptie the end of the black cable guard to the drill handle. Lead the rest of the cable around the drill trigger and ziptie it to the cable guard. Secure the cable as best as possible as it is prone to slipping. If you can pull the brake handle and the drill moves causing the wheel to spin then you are DONE!!!!!!

Step 6: YOU ARE DONE!!!!!!!!!!!!!!!!!!!!!!!!!!!

Picture of YOU ARE DONE!!!!!!!!!!!!!!!!!!!!!!!!!!!

However, something is bound to go wrong.
Most likely, your chuck won't be rubbing against the wheel hard enough.
So if your motor is running and you aren't moving, that is the most likely cause.
This machine went about 5 mph for me, about electric barbie car fast.
See ya next time!! Hope you enjoyed my Instructable!!!

Wow, this is so cool! I'm home schooled too, and I would't have thought of this. Add a 54V batt and bigger tires you could do wheelies and go off-road.

Dude congrats, awesome instructable!!!

PUCKA (author)2016-11-21

i make with brakes every for my safety ...and thanks for ideas.

machoturtle (author)2011-12-17

Awesome I'm gonna have to try this! Dude go homeschooling, i homeschool too.

SEKTHEBOSS (author)machoturtle2016-03-13

so do i

Homeschooling has its pros and cons...I say that because I am homeschooled, and it was okay; but I don't feel I got the best education out of it. Going to high school this year.

ViperSniper (author)machoturtle2011-12-19

im doing homeschool aswell

pie popper (author)ViperSniper2012-01-12

Homeschoolin partaay!! haha

Anyway... nice idea. It looks like it would be kinda hard to ride with the cord and zipties in the way though, what if you threaded those through the tube along the bottom? Your scooter has plugs in it, see in step one where you took out the break...

Good job though :)

jackjackboom (author)pie popper2012-01-13

my cable wasn't long enough to do that

Yonatan24 (author)2016-01-02

That's a great idea! How much does a drill like that cost at Harbor Freight?

bostroglav (author)2015-06-02

respect!... this is so simple, but I never thought about that... awesome!

Just a note to let you know I have added this to the collection: Cordless Drills Hacking for Other Uses !


Take a look at a bunch of project involving odd uses of drills.

and for even more drill info

My friend has one made by Razor- there expensive so this would be awesome! How fast does it go?? GREAT JOB!

jackjackboom (author)Owlgirl2012-01-01

about seven miles an hour

Dude, nice job! Making your own electric scooter at this age, thats pretty cool.


Owlgirl (author)jackjackboom2012-02-18

Thanks! I really want one!

pietzeekoe (author)2011-12-19

I think rubber would be a better alternative for the velcro because the hooks pick up every bit of lint they come across and i think rubber would have better traction anyway.

jackjackboom (author)pietzeekoe2012-01-13

it totally would
all i had was velcro

javajunkie1976 (author)2012-01-06

This is SO annoying, I just thought of this exact same thing two days ago and you beat me to it!!

Welsh is best (author)2011-12-20

good idea, could look better though.

That's a really nice little mod, thanks for sharing it with the world.

It's worth pointing out that you should check your local laws regarding such things. The rules vary and can be a minefield, so take some time to make sure you aren't going to land up with a fine or jail time before you start. I remember doing something similar when I was much younger and getting into difficulties for driving a "motorised vehicle" without appropriate license and insurance. Talking politely to the police and at least knowing the limitations of the machine meant that I "got away with it" but it could be a non trivial concern.

With that in mind, removing the Brakes and not providing an alternative braking system might not be a good idea. If you hack the trigger switch you should be able to move it right up to the handlebars without resorting to break cable and if you do THAT then a relatively simple mod will give you braking effect from the "EMF" of the motor, you might even be able to get some regenerative effect.

Extending the run time with a second battery is a good idea and if you DO that make sure it's another of the same type.

Finally, if you are hacking the battery, then it would make sense to hack the drill too, a lot of the case is empty due to the way the drill is used as a HAND tool, but is not needed for this application. See if you can make it more compact and try to improve the trigger switch/brake cable situation.

Your project is cool, thanks for sharing it, and keep having fun.

Oh and thanks for the advice about the laws.
I didnt know about that.

I didnt mention this in the instructable but the scooter cant coast because the drill wont spin after you release the throttle.

doby162 (author)2011-12-16

Wow, that actually goes at a decent speed! If you battery lasted long enough you could use that for short distance transport :o) Awesome instructable!

jackjackboom (author)doby1622011-12-17

I might but it doesnt go up hills very well.

tmfitzhugh (author)2011-12-16

For additional ride time you could wire two of those batteries together, + to + and - to -, this will keep the voltage at 18v while having a larger reservoir of energy. If you hook it up + to - you will have the same run time but 36 volts and probably burn up the motor, so dont do that lol. Pretty sweet idea and nice job on the instructable! Perhaps you have an engineering career in your future? Keep up the good work.
