You don't need to be an 'investor' to invest in Singletrack: 6 days left: 95% of target - Find out more
Rather than punting an old canti CX bike for a song I'm going to build it up with parts bin spares. It'll be cobled together with flat bars and a mountain bike drivetrain.
So show me your repurposed,upcycled, modified bikes. Anything now doing something it wasn't really designed to be used for.

My beloved Scapin frame as a 26 rear/27.5+ front singlespeed. It was previously a 69er.

I frankly have no idea what exactly the Planet-X Hammerhead frame was actually for, but probably not this
This is Cyril, photo from a while ago (usually use Marathon Cross these days). Sometimes goes into what I call Frankenbike mode, with 29x2.35 G-One up front and 26x4" JJ on the rear.
Inbred in sorta commuting guise...

I raise you a 29x2.4 Ardent front with a 26x4.8 Minion FBR rear...
Only ridden it up and down the road, can’t say I’m overly keen to try it anywhere else...
Dear god this thread needs a health warning!
Pass the eye bleach
My 9yo son's XC bike:

27.5" extra small carbon Haibike frame
26" wheels, carbon rims, DT competition DB spokes
Fox 32 Factory 120mm reduced to 80mm with super thin damper oil - works great for a 25kg rider.
Offset bushings in the rear shock to reduce standover and slacken the headtube to take into account the shortened fork
Full XT M8000 + SRAM NX 155m cranks
Total weight, around 9.5kg - lighter than my own bike as he's always happy to point out! Rides like a dream and is (IMHO) the perfect trail centre bike for him. In fact, now that I think about it, I should probably think about taking a spacer out of the forks as he's grown a fair bit since he first started riding it last summer...

That looks like the sort of bike that would be ideal for riding the trails north of Cardiff. Perhaps on a Wednesday night.
Indeed. If one's legs are feeling strong.

Either needs TT bars to make use of that downward aero gain, or a larger front tyre, something like 29x3.0 😉
I don't ride my odd combo often, but when I do, it's usually when I randomly decide to tackle the Meon Valley Trail.
I suspect STW would regard most of my bikes as Frankenbikes, but this repurposed Dahon folder is my most Franken...

(Being ridden by Steve of StrathPuffer fame)
I like to think of it as my most niche bike, in that it fits into several niches, recumbent, folder, fixed, odd sized wheels, front wheel drive, penny farthing. 🙂

That's simply magnificent.
Nice looking fork! What is it? 🙂
It's a nimbus 36inch wheel unicycle frame I think...

You commute with no front brake?!?!

Thanks!
Just been looking at Nimbus stuff, this must be the ultimate in paired down simplicity:

I’d lose teeth trying to ride that. I can’t even ride a normal unicycle!
That is possibly the most hipster thing ever.
Daern: Love that bike. Definitely inspiring me for a few years time. How old was your son when he started riding that, if you mind me asking?!
Some great looking bodge efforts. Whilst the big/small wheel combos are fun, I've got a special place in my heart for a thin/wide tyre efforts.
That is possibly the most hipster thing ever.
There's a pretty impressive video that goes with it but can't post because, you know, update errrrrrrg
