An exclusive look inside a factory and into how a modern bicycles are manufactured, from raw material to finished bicycle. Pole Bicycles, in Finland produce CNC Machined frames from 7075 T6 Aluminium. Here is how they do it.

nice look
Very interesting and informative video. I agree a very fresh and innovative approach to everything from design, production and everything else I guess.
finally a billet bike. I hate carbon bikes.
Cast it.
POLE is so NICE!

Presumably they leave a reasonable flange (on the inside where you can't see it) so there is some area for the bonding between the two halves? If it was bonded then machined down to ~1mm wall thickness that would leave very little bond remaining. I am impressed that they can get this process to work without visible seams on the outside and with consistent wall thickness. As he emphasises this is hard to get reliable.
I wonder if there have been any instances of bond failure in the middle of a frame tub: (MTBs get a very hard time and epoxy is good but surely not as good as the solid metal of an extruded, welded or hydroformed tube?
Would it fussy if I said 0.1mm is a lot
how do they bond two sides together?
Awesome COOL 😮🤠🤟
Unreal video, thanks Rob and thanks Leo! So cool to watch!
Dude is nukin futs passionate ❤❤❤
SORRY EBIKE? WHO CARES SIF THEIS WAS ABICYCLE ALONE THEN I WAS IMPRESED BUT A MOTOR FRAME? BUGGER OFF FAKER
havent seen a fully cnc frame beein created, misleading 🙁
Probably one of the worst ways to make a bike frame.
Good aluminum desin can be much better than carbon.
Many designers create stupid shapes with huge tensions.
It is possible to design light frame which will have 70MPa under 4G landing.
But most of design has about 150 or even 200MPa in case like that.
Frames are quenched and agged after welding (T6 treatment) but it isn't enough to prevent fatigue if design is bad.
7075 is old but very good alloy and after T6 tretment is more durable than most normal steel alloys.
But aluminum is almost 3x lighter so can be much thicker which gives smaller tensions in frame.
Welds even after T6 treatment are not perfect and design without it is very good idea.
When I was younger I thoud to creat frame made by two forged pieces but I,ve never finish it.
I stopt on repairing frames for people or designing and machining better links in case of repair.
But thanks for bicycle engeniering I was designer in automotive and now I am mechanical designer in eletronic industry.
Great to see someone who create so smart companie with smart design.
Interesting solution, but 0.1mm is not high precision CNC machine. Additive manufacturing is a better solution IMHO.

Great job on this video.
Doesn't come across as a paid promotion at all. Fascinating content.

All the big brands need to take this same approach and not hide how they produce thete products
This is such a great story and a delight to watch 👍
