I disagree with the above testimonials. Both Puchs (Maxi) and Honda Hobbits are fine but both have drawbacks too.
The Maxi’s interval tank is mighty inconvenient to clean out if it’s rusty but the hobbit tank is a horrible design to do the same. Pinto/Swinger or Free Spirit have removable tanks that are super easy to maintain.
Puchs are stupid simple. There’s only a dozen or so moving parts/components in an E50 and they are probably to most reliable, durable and forgiving engines I’ve ever worked on. Parts are cheap and available everywhere. The PA engine and drive system is a far more advanced design but It never liked having to drop the engine to get to the carburetor - which you’d have to do (repeatedly) when it gets dirty, and that Kehlin carb is bloody awful.
The Honda PAII is dual variated, which is great for rapid acceleration and climbing hills. It’s a system capable of amazing performance potential. Avoid the single variated PAI though.
Hobbit electrics are a dumb, fucked up mess. Just remove the headlight lamp and take a look at the rat’s nest behind it. I could go on nit picking the Hobbit but their engine is outstanding; everything else bolted onto it is way overrated in my honest opinion.
