weelye Children Electric Car DIY Accessories Wires and Gearbox,Self-Made Toy Car of Parts， for Electric Car Kids Ride on Toys

Amazing product. Converted my son's 6v power wheel to 25v and man its FAST! harness is a bit short for the mcqueen car but I extended it some and it works flawlessly. If your car has sound buttons thid will eliminate it but other thsn that the cheapest upgrade to go faster!

This was a really cool kit. It's geared higher than the broken power wheel drive so it cannot handle grass or inclines but it cruises on flat road. Came with a broken fuse which amazon quickly took care of.

I got these to convert a 6-volt one-wheel-drive Hello Kitty car to 12-volt 2-wheel drive for the traction and to use the same batteries as the other kids’ Power Wheels. Though the motors are a direct fit, the wiring is basically unusable, especially at 12-volts. The wire is way too small for the included 20 amp circuit breaker. It seems to be ~22 gage. The full motor power runs through the charging port (through some hokey charge interlock) that’s only rated for 7 amps. The included main on/off switch is only rated for 10 amps (stamped right on it), the others are rated 20 amps. The full motor power runs through it too. Even after rebuilding the wiring harness with 12 gage wire and replacing or bypassing the under-rated components, there were still problems. The motors spin way too fast at 12 volts. I mean WAY too fast. This was for a 3 year old and the HK car will easily outrun the 7-year old’s PW Dune Racer. On “slow mode” it is nearly as fast as the Dune Racer. I was letting the 7yo ride it around for a while but it blows through a 12 AH battery in 30 minutes and the motors get plastic-stinking hot. I put the 6 volt battery back in it and it is still faster than the original single motor. Although the motors are stamped “12V” they run the same speed as the original 6V motors at 6V.

Purchased for my granddaughter's VW Beetle car that had a 6v single motor setup. Another reviewer had the same model (white VW Bug) When it was delivered, I thought it was the wrong setup for how small it looked. I was mistaken as I took it out to my shop to check. It fit flawlessly, all of the wiring was the exact setup I needed. It would have been helpful if the motors already had the wires attached, but it was no problem for me to solder them on. If you're not handy with a soldering iron, I suggest getting small spade crimp on connectors to attach the wires. It was a snap to put it all together. Although if you're not a handy person, it could be challenging for you. It is fairly straightforward in how it gets attached. I would gladly buy another kit like this if I had the need.

Purchased this product. Installed fairly easily. Minor modifications needed to the cars drive axel to accommodate the new motors. It ran fine for about 5 battery cycles until the connector to the forward/reverse selector melted. I requested a replacement. Received it 3 days later. Installed it without issue. Ran 1 battery cycle and the same issue. Forward/reverse selector melted again in the same spot. Obviously this is not rated for the amperage uses. I'll be sending it back. Shame, as my son really enjoyed the increase speed and power.

I have had no issues with this kit since I started using it. I am using an 18V battery to power this and all of the controls and wires have been solid with no melting or shorting out. It has been driven hard for a few hours cumulative now and my son loves having the car ready to go always. The fast speed is quick so I have it set to slow speed which is still plenty for my 3 year old.

My grandson fried the motors on his Jeep going and down a hill repeated, like 4oo times in a row. I ordered this kit to repair it. The motors fit perfectly. It, took 15 minutes to change the motors out and then 5 minutes to figure out why it would only buzz and not go forward or reverse. You have to be sure #1 the motor leads on one motor are reverse from the other so that the wheels turn in the same direction and #2 that you the motor leads hooked up so that the forward and reverse switch is not swapped over. I recommend theis project to keep the little drivers on the Road

Fits and works, sadly it is the same crap that broke so easily on the original set up

👍

Pretty decent for what it is, it's a cheap wire kit, providing you change out all the cheap connectors it is a decent unit with a lot of torque, can mow over just about anything and back it's self out, only issues I see as previously mentioned are the connector fitment, caused my forward/park/reverse switch to burn up the contact after about 4 hours of use, supplied 12v at 20amps with a drill battery kit, little man loves it not crazy fast, goes about walking speed in low, and jogging speed in high, about 2.5km/h, and 5km/h
