When I got the frame it had a bottom bracket adapter with it.


but it didn't fit quite right


so I had to shave the edge off of it.


And then I bought a sealed bottom bracket for it which is the best $20 I've ever spent on a bike. I'll be going with these as often as possible.


I also bought the cheapest crank set I could find,


I had to pull it in close to the frame to get the larger ring to line up with the wheel. That meant I had to grind some tabs off of the inner chainring (it's all welded together). Not the ideal situation but the crank was literally cheaper than buying a round chainring to replace the biopace I had on the first 3 piece crank I put on here. The Biopace would have worked but I wanted that crank for a different bike anyway.

looks good.

the rear is an Atom drum brake

Refining this into more of a clunker. Wanted something somewhat lightweight and with clean handlebars. Also wanted bigger tire clearance and I really think big 26inch has a lot going for it if your neighborhood doesn’t have the best roads.

Down to 26.4 lbs. likely close to the lowest weight this will go.

Will save some weight by switching cranks to something like a Sugino 75 copy. Will add some weight by installing beefier pedals.

I think right now it’s 40-22.
Thinking about setting up a set of wheels with off road oriented tires with this gearing.
Then a more street oriented setup with an 18t cog.

ETA. The chain line is off a bit. I figured it out after the chain dropped a couple times popping wheelies or hopping curbs. Hoping by switching cranks to something with a 110 or 130 bcd I can adjust the chainwheel in with washers.

And… I think the bearings in the BB ate the cage on the right side. Have only had the rear wheel apart so we’ll see.

This is looking good! Since you have to get into the bottom bracket anyway, can you move the existing chainring in with a shorter spindle?

SkinGriz

I don’t know. The crank arm doesn’t have traditional bcd arrangement or a one piece pin. So I think it’s more likely that the chainring won’t be reused.

And I would like the option of changing chainrings without removing the crank arm.

As a teenager I had the cromo GT splined cranks on a BMX bike. Some of my friends had the similar Profile 3 piece cranks. They weren’t at all heavy and we’re ridiculously strong. All that to say I’m not convinced aluminum is always the higher performance material.

This.

Again, this.

The only thing I can add is BMX is the way to go in your case. it's easy to adjust the chainline with spacers
Those euro adapters are great, you get a bmx bb

The red one is cool...
and cranks like these

My set up The chainline is purrrfect.

Cat tested and approved.

I haven’t measured yet but I think the BB shell is the old MTB dimensions. It looks skinnier than the Ashtabula BB shells on my other bikes.

I think it might (big maybe) be square taper under the arms.

I’m going to post a question in mechanics question. Can you please give your perspective.

Schweinhund

schwinn cruiser is a 68mm bb. old BMX used schwinn as a standard.

SkinGriz

Thank you.

SkinGriz

That’s cool.

Can you give us details on the rear hub?

victorm

wheels are from 1954 CCM that I sold to a buddy. He gave me the wheels and tires back cause I liked them so much. Ended up with this frame so figured I’d put them together.

SkinGriz

Is there a grease port or is it just weird reflection?

victorm

yes grease port is brass nipple on hub body

My wife likes an upright riding position and is a pretty weak rider. I sold her city bike, and got her this Electra Townie GO! 7D eCruiser, so she can keep up.

It has 36 V, 7 Ah worth of batteries in the downtube. That's not a lot as eBikes go, but enough to keep her going any speed she wants up to 20 mph. It has a simple display with 5 green LEDs showing battery level and 3 red LEDs showing PAS level. (Power Assist System) It has a a nice quiet 250 W motor in the rear hub, and the downtube isn't too huge, so people don't always notice it's an eBike. It has a 7-speed cassette; just the one smallish sprocket in the front. Granny gear is VERY low; walking speed, so hills are no problem.

This past week, she bought the Electra luggage rack and shopped at Target and found a basket she likes, which I zip-tied to the rack. I plan to have her join a coffee ride with my local bike club Saturday morning.



The bike is the center one in this pic, and the wife is on the right.

Wife's Electra Townie GO! 7D is in the middle.


Just before riding it home on the first day.

Did a tuneup and complete scrubbing/polishing of this beauty at the shop.
It a two speed using the lever to change speeds. It was frozen but a bit of a soaking in mucoff did the trick. It came out great and the owners...original mind you...loved it. Rode it a bit and it is a nice ride, very smooth. Just a coaster brake but it works.
A Schwinn "Corvette"...seems to be around a '60's vintage...wonder if Chevy said anything.

SkinGriz

I think a corvette was a type of small sailing ship.

Beautiful bike. Glad owners are happy with it.

Kai Winters

You are correct on both counts...

Schweinhund

A small speedy ship, used to harass larger ships in battles.
Had a car named after it too.
