It isn’t really identifiable, it’s not the original bike that left the factory. The bike has been altered a lot from new, it looks like currently it is a singlespeed, flat bar conversion with front brake only; not legal to ride this on public roads in sensible countries.

The frame is an Orbea brand, can’t see the model name but the carbon rear stays on (I think) alu frame date it by a few years at least. You can look at old models and compare this feature to narrow it down.

It has a double chainset but no front derailleur or chainkeeper. I can’t make out any shifters in the bars. There may be a rear derailleur acting as a chain tensioner, or it is a dedicated tensioner, but there is no cable run to the rear either. So no shifting.

The wheels are Bontrager, a Trek brand. They have a low spoke count and are probably road wheels, so likely have a freehub. Hence saying it’s a singlespeed. You can check by looking at the rear wheel for a freehub.

It has a couple of Shimano parts, look for part numbers on these (like BR6600), they might help to date the bike, but they might not be original.

If it’s fun to ride, enjoy, but it’s a conversion made up from old bike parts so identifying the ‘bike’ is more of a narrative answer. You might have luck browsing through old Orbea models to identify the frame.

  • Fixed with a front brake is generally legal, though freewheeling SS with no back brake wouldn't be. So it could well be street legal – Chris H Jun 04 '19 at 07:12

    Would you mind explaining how you are arriving at the conclusion that this is a singlespeed? I see a double front chainring, as well as a rear derailleur. – anderas Jun 04 '19 at 07:17

    @andreas I doubt you could find a cassette with the biggest sprocket that small. So, it's possibly a two-speed conversion with the RD working as a tensioner, although I'm not sure I see even one shifter on the bike. – HAEM Jun 04 '19 at 12:17
  • @anderas I have updated the answer with reasons – Swifty Jun 04 '19 at 12:33

    @ChrisH totally right, fixed is distinct to freewheeling. I’m sure we’ve both seen enough arguments for and against no rear brake on fixies to last us a good while so I’m not starting one now ;) – Swifty Jun 04 '19 at 12:39
  • @Swifty Especially as this has an RD (I couldn't see that on my phone). – Chris H Jun 04 '19 at 12:44

    @HAEM You can certainly buy 11-21 cassettes in up to 9speed (and there were 11-19s in 7speed). There's a cable going to the rear mech, and one dropping down behind the head tube - probably an integerated brake/thumb shifter unit. But there's no front mech, meaning it's seriously cross-chained to get a fairly high lowest gear (you could hand-shift it for climbs). My ID: one that needs some work to be useful; it would be worth it if you had a source of cheap parts – Chris H Jun 04 '19 at 12:49
  • @HAEM I concur the sprocket looks a little small but hard to be objective about it so listed other objective reasons – Swifty Jun 04 '19 at 12:56

    @ChrisH I’m viewing those additional cables as belonging to the red ‘scooter’ in the background – Swifty Jun 04 '19 at 13:01
  • @Swifty that's also possible I suppose – Chris H Jun 04 '19 at 13:03
  • @HAEM How small do you think it is? Shimano 105 (matching the cranks) includes a 12-25 -- could it be that? – David Richerby Jun 04 '19 at 13:21

    The gear doesn't look all that small to me, could easily be a 25 or a 23. 53/23 would also work as a hypothetical single gear ratio. – Andy P Jun 04 '19 at 13:51

FORK

The fork may or not be original, but by reading the words we see it is a ZICCS FCM which was stock on many Orbea brand bikes as well as sold separately.

It is a carbon fibre fork and weighs around 390 grams alone.

FRAME

Can't see any branding other than Orbea, so its reasonable to assume that's the brand. Their modern bikes have the model written clearly on the outside, so it pre-dates that styling.

We can see its probably a carbon rear, so the seat and chainstays are carbon fibre. The main triangle appears to be Aluminium, with the rear bonded in.

I would recommend you re-fit the rear brake, for safety.

SUGGESTIONS

I suggest you try registering the bike by serial number at https://www.orbea.com/us-en/access-register and see what happens. You'll find the serial number on the Bottom Bracket, or somewhere else on the frame.

If that doesn't help try contacting Orbea directly at http://content.orbea.com/us-en/ and see what they can tell you from the serial number - what model it was when it left the factory, but nothing about the changes.

You have a nice aluminium-and-carbon-fibre frame, just maintain it and ride it.

After some searching, the frame looks very similar to both:

Orbea Marmolada from 2004 - notice the seat stay bonding looks very similar: https://bestforbikes.com/uploads/data/b_256493/2004_Orbea_Marmolada.jpg
But the chainstay appears to be painted metal.

Orbea Mitis 3 from 2004 - which has carbon for both seat and chain stays. https://www.bikepedia.com/QuickBike/BikeSpecs.aspx?year=2004&brand=Orbea%20&model=Mitis%203%20Double

Now I'm not saying its one of those, but the 2004 era would be about the right year, plus or minus 2 years. Any earlier and carbon wasn't used like that.

So your other option is to find an Orbea catalogue from 2003~2005 and start browsing through the pictures.
