I have just done this with my boys bike. Well i had to as i bought the bike second hand from the pawn shop. When i left the shop the originsl battery died instantly. The shop refused to give me any money of for a new battery. Luckily i found your video and late that night i rigged up the upgrade. My boy was absolutely buzzing. Going to take it on some mini adventures, fishing and camping. Cant wait.
No point waiting mate … turns the thing from a gimmick into a real bike. Here’s a link to a cheap and fast shipping Makita socket… (if that’s the brand you have) www.ebay.com.au/itm/154923800276?mkcid=16&mkevt=1&mkrid=705-154756-20017-0&ssspo=tbkjwddns4k&sssrc=2349624&ssuid=1Qhjbg6xS92&var=&widget_ver=artemis&media=COPY
I have to do this asap! My parents bought my runt lil 6 yr old one and he can run faster than it! In your video it seems to be atoeast twice as fast than the 12volt he gotnon it now factory! Thanks for the video! Since it’s hooked back up that way the charger still works that comes with it right?
@@joshuacraft493 it hammers man. Still lacks torque, uphill it dies in the arse, but keeps moving. On flat hard surface, like our dirt driveway, it’s too fast. And lasts all day. I think I’ll get a 36v motor and run two makita batteries in series next, when he gets a bit bigger. That’ll require a new controller though, and a bit more work. But absolutely, this first mod is best bang for buck. Turns it into a useable product for almost free.
Me too I was incredibly disappointed it claims to go 8 Mi an hour for up to 100 pound person and my barely 40lb 5 year old gets on it and it can't even go in the grass on a slight incline I was very disappointed I wasn't exactly expecting much but I figured a bike with a rubber wheels that could carry 100 lb could at least take him through bumpy grass but I was sadly wrong
I don’t have any videos on soldering, sorry. But plenty on RU-vid. It doesn’t really have to be soldered, that just makes it a better job. If you just strip the wires back nice and long, and twist them together really well. Wrap tape around it, it will work fine.
We have the same exact bike and I've had a cheap 18v battery on it but it only lasts about 10 minutes. Any idea how long yours run before it needs recharged? I'm trying to see if it would be worth it to spend the money on a good 18v battery. Thanks
There’s only one thing to buy, and that’s the adapter for the battery. Just jump on eBay and search for “makita battery adapter” or whatever brand you have. I didn’t buy anything else. Just that.
Quick question, did you use a Makita battery with a star on it? Meaning it has a built in BMS (Battery Monitoring System)? Mine gave out. Suddenly goes full throttle on its own.
Hey man, that’s really weird. It literally doesn’t matter what batteries you use - the voltage is 18v and that’s all the controller sees. Thats really weird!! Don’t stress, it’s easy to replace that motor controller with another (rated) one off eBay. They’re really cheap. They all typically use the same connectors, in my experience. Super weird that yours did that. I had no trouble with mine until the kids outgrew it. I recently dropped an 800w motor in it, with a new 36v controller, and rigged up two 18v batteries. It goes absolutely ham now. Pretty easy upgrade too. Talk more on messenger about that if you want.
@@coryjeacocke yea, I can send a video of the weird experience but I’m charging the battery as of now and trying to troubleshoot in my mind in the mean time while everything charges. Can I message you?
Mines still going hard hey … The kids are getting too heavy for it though, the 100w motor is a bit gutless. I just ordered an 800w/36v motor and controller for AU$140, so I’m going drop that in it and see what it can do. 8x the torque will be fun to see.
No. The “amp-hours” are simply the capacity of the battery. Think of it like the amount of fuel in the tank. A 1ah will perform just as well, but it will go flat quickly. The voltage, on the other hand changes the speed. So even though this bike was designed for 12 volts, giving it 18v makes it 1.5x as fast.
@@coryjeacocke I did the same mod you did, it feels like. It's dying even tho I used a DeWalt 4 ah. Could it be because my bike is a mx 350 and the watt requirement is more than a 125? Thanks
Might work … 20v might let the smoke out of the controller, I’m just not sure without information on it. 18v’s fine. 20 might be okay … one way to find out ….
Nah, the original charge port would deliver 12 volts … just unclip the battery and charge with the power tool charger. I’ve since upgraded this again, to a dual-18v, 800 watt motor and 2 battery holders. It’s awesome. I’ll have to make a video on it.
