I can’t speak for the ease of installation, but it is good value for the money, considering the prices of similar products. I can’t give specifics on the motor life, speed, or functionality since it didn’t fit. Make sure you take measurements or check if it will fit before you buy. Other than that, it works since I tested it. Review: Unreliable Part - Zero stars if that was an option. Child was so excited to be able to drive his power wheels again. One motor installed and with basic driving, the motor burned out within 5 minutes. (Parent is a crane mechanic, we know this was installed correctly.) Asked for a refund. Would not recommend this part for a replacement fix. Unhappy child and parent. ## Features - Attention: The model is RS550, which includes 7 different motor teeth. Before purchasing, please compare the size of the teeth and the size of the motor (to determine if the motor is damaged, connect the two polarities of the motor directly to the battery and check if the motor is rotating) - 2Pcs 12V RS550 40000RPM Electric Motor Drive Engine For Power Wheel Motor Upgrade,High Speed Motor Gearbox Accessories for Power Wheels Ride On Car Replacement Parts,Suitable for Various DIY Electrical Projects - [Advantages]: The Motor Adopts A 12V 40000rpm High-Speed Motor, Which Matches Pure Copper Winding Coils And High-Quality Cooling Fans, Which Can Greatly Improve The Speed And Life.
