Italian design studio JonnyMole has published details of its Dream Machine 2.5 concept bike which it reckons is “the future of gravel cycling”. It’s certainly radical, so let's take a look.
“The Dream Machine 2.5 merges advanced technologies with a captivating design, featuring a unique dual-frame that not only gives the bike a distinctive presence on the road but also delivers superior performance and the ability to integrate a wide range of accessories,” says JonnyMole.
A dual-frame? What does that mean?
The vast majority of bikes have two chainstays and two seatstays in order to accommodate the rear wheel, and JonnyMole extends that division forward, giving its bike two seat tubes, two down tubes, and two top tubes.

Some conventional features remain. You get just one bottom bracket shell, and the dual top tubes and down tubes merge towards the front of the bike. The head tube is a single piece too, although the fork has an external steerer.
Why not go with a more orthodox design? JonnyMole reckons that its dual-frame structure “allows unprecedented customisation, enabling cyclists to seamlessly integrate bags and luggage to tackle any adventure with style and convenience”.

Check out the Instagram video (below) and you’ll see what JonnyMole has in mind. A water bottle fits between the tubes, and bags, presumably made especially for this bike, also slot into the spaces.
The dual-section seat tube is interrupted, merging into extended seatstays which go on to join the top tubes. This bit of the design is a little like you see on Trek’s seventh-generation Madone and its mystery new bike that’s currently being raced by Lidl-Trek in the Dauphiné.

The idea is that it is cantilevered “to ensure a smooth and comfortable ride even on the most irregular paths”. In other words, the lack of support behind the top sections of the seat tubes are intended to allow some down/up movement at the saddle.
Speaking of the saddle, that’s integrated into the frame.
“With a rear opening for smoother and more flexible riding, it follows the cyclist's movement on any terrain,” according to JonnyMole.
Okay, but we know how fussy some people are about their saddles – both the model and the positioning – so integrating it into the frame design seems like a bad idea. Interesting, but it’s a hard no from us.
The JonnyMole Dream Machine 2.5 also features integrated lights and brakes.
“Not only do they improve overall aerodynamics, but they also offer a practical and aesthetically pleasing solution,” says JonnyMole.
Up front, the fork integrates with the frame at both the top and bottom of the head tube and melds into the stem and handlebar. Oh, and with yet more integration, this unit also features aero bars. Down below, the front brake bolts to its own special extension behind the dropout, and there’s a vaguely similar design for the rear brake too.
We know what you’re thinking: how would you tweak your ride position? Also, if you damage the handlebar section, say, that’s a lot to replace in one go. In JonnyMole’s defence, this is a concept bike so it’s more about ideas than practicalities. Function usually takes a backseat in these designs.
What do you reckon, though? Good ideas or a load of old nonsense?

Public Safety Announcement: Don't ride this on Naked Bike Ride days if you have male anatomy.
At least you won't need to dismount for a no. 2!
Well, that raises the issue of whether mudguards can be fitted
There will be some special 'integrated luggage' I'm sure.
I'd rather keep my integrated luggage where it is, thank you very much
the integrated aero/handlebar is nice and actually looks to be the correct dimensions/ratio. however, imagine having to clean that downtube channel after every ride.

It looks like it's trying to reproduce by fission.
Presumably each half gets one wheel and regrows the other*? Is this what these thru-axles are for?
* Thinking about it I've seen bikes in the middle of this process about town, leaning on their drop-outs. Not infrequently they've crawled down an alley or into a bush to complete their regrowth in a sheltered location.
Mitosis, surely? Fission would involve smashing the bike into something to split it apart.
Could be some crazy Doctor Who thing going on

Was thinking more macrobiology than micro- or physics - like starfish:

Although only the wheels have radial symmetry here.
It looks like 'the bike of the future' as viewed from about 1978. Reminds me of the future-cars in Logan's Run.
I've always wanted a bike that makes it more likely I'll smash the side of my knees on the top tube while pedalling
These fully integrated concepts seem to appear every few years and demonstrate a basic misinterpretation of the bicycle. Being that bicycles are powered by the rider they are inherently performance based machines, and beauty arises out of that function. So a design exercise like this one will always comes at a massive compromise of something else because it puts form over function, whether it's day to day practicality, maintenance, reliance on proprietary parts, weight, lack of customisation, etc.
I always get suspicious when designers get too far away from the good ol' double triangle frame design. The "cantilevered" seatpost looks odd to me as it's not as fully cantilevered as some other designs (i.e. the split going all the way to the headset) which means that there's going to be lots of stress halfway along the top tube which isn't usually a strong part of the frame. I'd prefer either fully cantilevered or stick with the traditional design.
