There are many reasons that sales of PW50 and PW80 models are so high, and here are two:
1. Secondhand Pee Wees hold their value really well
2. Secondhand Pee Wees usually have a waiting list of who’s going to own them next that includes younger siblings, cousins, friends and so on. Low-stressed, throttle limiter-equipped two-stroke engines and rugged auto transmissions (PW50: full auto, PW80: semi-auto), or the light, easy to control running gear and brakes.
