Follow along as I experiment to see if drill batteries can power a 72v go kart motor mounted on a bicycle!

I believe a hub motor is the way to go instead of a mid drive like this therefore you can keep your peddles because soon as that chain pops it will be a long push back to the house if you is far away of course.

Cool project, and you have some clever work with the drivetrain there. Pushing 3,000 watts at 72v will require 41.67 amps, and I don't think those Ryobi batteries can deliver that. I have some myself that were given to me, and it's unfortunate that they do not give the output amperage. I did find a website that claimed they output 20amps, but that seems optimistic based on the weak performance of the tools I have. The go cart battery should fix that though! Thanks for the video!

There's a reason no one else has done this, this is the most ridiculous thing I've ever seen, as a builder I'm embarrassed, for the same price you spent you could have had a bad ass bike. I would normally never do anything like this, but thus is ridiculous.

Redesigning the wheel here. One plus side is 4 of those batteries can go on a plane. My batteries are to big to fly. Update: So now your using a big one.

what range could 4 batteries get?

@@Eric_Tennant my initial test ride was with 4 4ah batteries and I got about 3 miles. My first test ride on 8 batteries, adding 4 6ah batteries I went 5 miles and all 8 batteries were showing 50% the test ride after that was when the batteries started failing on me, 5/8 batteries were no longer able to be charged

@@campbelloffroad3660 Think you maybe pulling more amps then these can handle triggering the BMS to turn off the battery. (3000watt / 72v) = 41.66amp. So with 8 each one needs to putout 21amps. Happy your going with a pack. As I could see drill batteries costing more in the long run.

@@Eric_Tennant Ahhh thank you for pointing out where my math was wrong, I was doing 42 amps/ 8 batteries and didn’t understand why they couldn’t handle it. Makes sense now!
