My Speed P8 has well over 3k miles, no exact numbers but suffice to say that I've
used the hell out of it. It was never perfect in my eyes but it completed its job
admirably. It's to the point where multiple parts need replacing/upgrading and I am
also becoming concerned about long term problems on frame joints.

Replaced:
Bottom bracket
Rear wheel

Needing replacement:
Drive train
Front wheel (hub needs overhaul)

Or just replace the whole thing and start from scratch... I keep looking at a Downtube,
a new(er) P8 (don't like the new orange paint :twitchy:) and possibly a Brompton.

Suggestions?

well if i was you i would see how much second hand jetstreams are selling for, if you are happy with the figure sell it, also if you are not happy with the bike i would also sell it, if you adore your bike and you dont want too get rid of it because of all the good times you have had on it replace the parts, although it would be costly, also bromptons are good bikes susposed to be best fold up bikes in the world!, so it should be reliable, a nice ride, folds small, nimble, and durable, i would get the brompton instead of downtube if i had the money and i was in the position you are in but its up to you :).

hope ive helpped :)

1) Be green. Repair it.
2) Be charitable - repair it and donate to a bike charity
3) Part out the frame and good bits on Ebay
4) Trade it on here.
5) Keep it as a 'project' & get a new bike
6) Hang it on your wall as 'art'
7) Turn it into a musical instrument
8) Make an electric bike out of it
9) Fix it up for another 3000 miles
10) Put knobbly tires on it and finish it off - off-road.

ohh can i trade bikes or sell bikes on this site?

Get a new bike and make the old one a singlespeed/fixie.

I'd repair it, maybe do a few upgrades and get another 3000 miles out of it. I'm sure there are others on this forum that have had bicycles for longer than I, but I just took my 17-year-old Raleigh Rocky to get her ready for winter: rebuild the bottom bracket and drive train, relace the rear wheel and replace all the cable housings. There's something very comfortable about an old, well-looked-after bicycle. I hope that the Giant Halfway I bought this year will last me half of the near 40,000 kilometres I put on the Rocky.

. . . I am also becoming concerned about long term problems on frame joints.

. . . the frame is my primary concern. No point upgrading components if the joints fail in the next 1000 miles.

Do you have some reason in particular to suspect the integrity of the frame? Any symptoms? Or is it just that you are privy to a history of abuse? 4000 miles seems to me to be a ridiculously short lifespan for a bike, even a folder.

Repair. Front hub overhaul is a piece of cake (assuming it has cup&cone), and drivetrain replacement is routine for every bike. Just get a new chain and rear cassette and you're good to go. Cost will be less than $50 all up.

I don't mean to be a smart asz, but how in the world did you wear it out after only 3,000 miles? Do folders wear out faster than a non-folding bike? Why for instance, did you replace the bottom bracket with less than 3,000 miles on it? Was it a factory defect/recall item? I have bottom brackets with over 60,000 miles on them, and that is without disassembly/cleaning and re-lubing (I don't have the crank pullers). The drive train (cogs, derailure, sprockets, etc) should last a minimum of 10,000 to 20,000 miles with proper care, on any bike.

You say "I've used the hell out of it." Sounds more like a case of "I've Abused the hell out of it." to me.

If you did not abuse it, thanks for the warning, and I will avoid the Speed P8 when it comes time to get another folder.

Have you broken any spokes on the front wheel? That would be rare, as especially with panniers the rear wheel is the one that is loaded. As long as the front spokes are tensioned well, they should outlast the rim. I would leave the spokes (if it's not broken don't fix it :) ) and try to form an idea of the rim wear. Wet riding will wear them out rapidly. So bad, that I have stopped altogether using my rear brakes (except in emergency).

Last week I replaced my front tyre, and then found the bearings were rough and rumbly. I have bearing balls in my parts cupboard, so a quick clean of the races, new balls, grease and away. Probably took 30min.
