What bike is this

[JohnnyM]

I'm looking through marketplace and see this bike. Can someone tell me what it is please?

@JohnnyM It is a "bike boom" model from around the mid-'70s. If in perfect condition, serviced and ready to ride value is ~$100-$150 depending on exact brand, model, and components. Not something to invest in.
If your bike it is worth cleaning and servicing to ride if done at low cost. Good set of new tires runs about $50 (cheapos at $30/pr); I would not spend more than another $50 to service unless it was your only bike required for daily commuting.

Low end recreational "racer" with steel cottered cranks, "safety" brake levers, heavier steel components, etc.

Those features do not necessarily mean a low quality bike, but instead a low cost mass produced bike where if quality control was good so is the frame with low cost/low performance parts. I assume the frame is made of high tensile straight gauge steel tubing. Occassionally some brands had a nice frame (Reynolds, Columbus, etc.) used on higher models, but bedecked with the cheapest parts to encourage novice racers who would upgrade parts instead of getting a more expensive bike to start. Those are not common, but if the frame displays a tubing manufacturer decal it might be a decent frame.

Perfectly good bike to ride. If steel rims braking will not be good; especially in rain (use newer pads; better yet find some cheap alloy wheels).

If for sale a good offer is $25. If bike requires any major service requiring parts (e.g. bad bearings) it is best left alone.

Thank you for a great reply. I ended up passing as they wouldn't reply to the ad. I ended up buying a Puch frame.

@JohnnyM Glad you found something. Puch made some great bikes with quality frame tubes and parts. Same company who made Austro-Daimler. With few exceptions the Puch is most likely a big upgrade (even if a cheaper model) than the example bike you posted.

Can you submit a photo of the Puch please?
