Intro: 5 Minute Electric Bicycle



* Since you asked, here is a link to a video of the bike in action.

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.

Step 5: You Are Done!!!!!


You are done!!!!!!!! Hooray!!!!!! However there is one big declining factor in this instructable, You cannot COAST. This bike also doesn't have a whole lot of economical value it only goes about as fast as a rather drained barbie jeep. It is more just for fun. Or it can be used for riding around the block and laughing maniacally and scaring little children all at the same time!! Or looking cool while trick or treating. Maybe it does have some economical value. Just remember to use a drill that you don't use a lot. I got mine from harbor freight for $15.

    A spring, small board, hinge and a second brake cable will give you a disengage option so you can coast

    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.

    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.

    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...

    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.
