Used bikes are really variable in price, from trash-day free to most of their brand new price.

Look for a 26" wheeled mountain bike with flat tires (which might only be flat from sitting around). That's a sign that the seller is just looking to be rid of it. Get one with a plain steel fork if you want a front hub motor, or minimal weight and maintenance. Suspension fork is fine if you want a rear hub motor.

Stick to brands that were sold in bike shops, not department stores or mail order. That way you know it was at least set in order one time, and isn't made from compressed garbage.
This is to express my gratitude to Justin of Grin Technologies for his extraordinary measures to save this forum for the benefit of all.

Don't know where you're located in the US, but Craigslist usually has tons of mid-90's steel-framed bikes in the $100 range. IMO, these are great for converting. As stated above, get a good brand. I've got several that were made in Japan (Diamondback Axis, Fuji Mt Fuji and Schwinn High Sierra), and have been superb.

Goodwill and other thrift stores often have decent bikes for $20 or thereabouts; most will need some to all of the rubber bits replaced (brake pads, tires, tubes, sometimes seat and grips and such), so they'll still end up costing around $50-100 (depending on what bits you already have) once fixed up. (most of them sat around in someone's garage or yard or whatnot for decades, often are 1980s or 1990s MTBs, sometimes road bikes).

I used to buy them up just for the pieces and frames (since I build wierd bikes and stuff from them), but I still see them quite a bit.

Of course, most of the stuff is just wallyworld junk, but there are good ones in there.

I built everything using $50-$100 10-20 year old mountainbikes from craigslist early on. And i typically bought used parts from my local bicycle collective.

Only recently did i start spending.. gasp.. $200-$800 on used full suspension mountain bikes and semi recumbents on ebay.
Efficiency is everything :bolt:

My first major build: 1.6kW 8T MAC motor on a Trek 4500.
The new all-arounder: Leafmotor 1500w @ 4kW on a Turner O2 full suspension.
The monster scooter: 20" eZee on a Cannondale Semi Recumbent.
Whipper-snapper: ? on a lightweight BikeE Semi Recumbent

It may not be the cheapest way to go, but IMO, it doesn't cost much to get a nicer donor bike in the form of a mountain bike w/ full suspension and disc. brakes.
In general, used mountain bikes are going to be a great value. Many folks. buy them, try them out a few times, find out how much work they are and park them. Compound that with the trend of technology that is moving so fast, it has clogged Craigslist with '90's up to fairly recent mountain bikes that nobody wants. 26 inch wheels, which work so well w/ hub motors are considered de rigueur and a few ounces that matter little to Ebikers are a big deal to serious MX'ers. That which is obsolete to them are perfect for us.
I bought all three my donor bikes(a '03 and two '06's) for half of the MSRP and all three were "show room floor" condition having only been used 2 or 3 times.
I came to this past-time from the World of Japanese sport motorcycles and I like the Fox shocks, shinny linkages and other bits of Bling.
Yet still, many today promote the idea that suspension detracts from the "bicycling feel", to which I would ask, :how many ebike builds say true to the concept of "bicycle first"? At least for very long.
I would summise that thoses that give weight to the negatives of suspension , live where the roads are better that I see or maybe, just better riders. Try as I might, I'm forever hitting things I didn't see. Things that might not matter much @ 15 mph, but sting @ 25 mph. My full suspension bikes have not added much maintenance and years later, are still a joy to ride.
The fact that I love my ebikes so much probably have something to do with the rolling stock I selected to start wirth.
