## Customer Reviews

### ⭐⭐⭐⭐⭐ Easy
*by K***A on August 16, 2025*

Kids love being able to ride their bike again! Came as it was described good quality at a great price. Super easy install!

### ⭐⭐⭐⭐⭐ The kids love it
*by L***A on March 20, 2025*

Great little engine! Fast shipping! Got this as a replacement for one of the kids little off-brand atvs. Bolted right in. Sounds great! East to install. There was no instructions for the wiring harness so there was a little trial and error hooking it up but works great. Starter solenoid died after cranking it over less than 3 times trying to get it started for the first time but luckily I had the one off the old harness. Get a better air filter. The one in my kit was just foam and already ripped and crumpled. Oh and the shift lever is unusable in my application. I honestly don't know what it would actually work in. LolOverall is it perfect? Nope. But I still have it 5 starts because, the shipping was really fast. Faster then expected by 3 days! Engine is nice. Sounds good. Direct bolt in replacement. Some of the accessories that came in the kit were a little chincy and unusable. Overall it's a great deal

### ⭐⭐⭐⭐ Runs great.
*by C***R on August 9, 2025*

Runs great. The shift lever that came with the motor did not fit. Contacted seller and they gave me a partial refund. Other than that the motor seems good.
