Sub-Cub Motorwheeler: Rare 1967 Honda P50

This is from the site Bring a Trailer (https://bringatrailer.com/) ...

This 1967 Honda P50 is small, rare and interesting, marking the last time the company built a motorwheel setup where the drivetrain is housed entirely within the rear wheel’s hub–it’s not a two-stroke either, but a 49cc unit with a tiny overhead cam actuating two diminutive valves. The seller has owned it for five years during which time they’ve done a top end rebuild, fitted custom-made replacement O-rings to the carb and installed what sounds like an NOS exhaust. Overall condition looks quite good, and sale includes a full factory tool kit, dealer assembly, owner’s, parts and service manuals. According to the ad it starts easily, runs very well and will do an RPM-limited 26 mph flat-out. Find it here on eBay in Superior, Wisconsin with reserve not met. Special thanks to BaT reader Markee for this submission.

Apparently the entire bike, fully-equipped and ready to ride weighs only 99 pounds–good thing as the little OHC single makes just 1.2 hp. Reads the ad: “This is actually a rare bike. It is NOT the USA Spec Model but the Export Model as identified by the ‘E’ in the Frame Serial Number. It also has the Non US Taillight and headlight assembly to also identify it as such. To add to its rarity is the unique light green factory color. Most were blue or red. Another rare option on this very unique bike is the full working turn signal option.” Luxury!

As the seller notes, this is more of a moped than a bike–note the pedals for starting. It’s a neat looking little thing, and would probably be a lot of fun to buzz around neighborhood streets with. The seller has it registered as a vintage motorcycle on a collector’s plate. Brakes are big–by bicycle standards, and controls are very simple thanks in large part to the simple fixed-gear/slipper clutch transmission built into the rear wheel hub in-unit with the engine.

There’s a speedometer but no odometer, and the seller admits they have no idea what true mileage is. These things were bought cheap, used up and thrown away, and though they sold in fairly big numbers in Asia and Europe, survivors are now rare. This one shows just enough patina to be charming, but overall remains in what looks like very nice shape.

Soichiro Honda strongly disliked two-strokes, and it’s not uncommon even today to find sub-100cc Honda motors with overhead cams–half a century ago the setup would have been especially novel. Again, from the ad: “There are a lot of new items installed on this bike. A full new exhaust system (It looks cracked in the pictures but is not) is just the starting point. I had O-rings made to fit the carb. You get a full extra set with it. These were not available in any way. It runs perfectly and starts very easy. Top speed is 26 mph. I did a quick top end overhaul on the bike. All that was required was to clean the seats and valves.”

Once more from the ad: “It comes with a ton of hard to find vintage paperwork all organized in a binder for you. The paperwork includes an owners manual, service manual, parts manual (US and Export), dealer assembly manual and more cool items. The complete tool kit is there also.”
