I do not get the reason for the black knob on the front of the bike. Maybe it acts as a kind of spacer if you use the optional bag-hook on the bars. It does however in some way make the bike look a bit strange for my taste.

It costs ~1700 plus tax in Japan, so it is not cheap - but seems to be very well made. At 12 kg it is not terribly light, especially for a naked bike w/o fenders, rack and lights - but it has an internal Alfine 8-speed hub that adds to the weight. Still a bit on the heavy side. The 18" tires (like the birdy) are ok, but limit the choice of tires a bit.

A very fancy design, well made, already an interesting line of accessories - it looks like somebody has realized his personal dream. Great thing and looks amazingly well thought trough. Rear frame design close to Birdy and Helix, split main tube was AFAIR seen on some prototypes of the Curl. The motivation for the bike sounds a little bit like the one of the creator of the Helix (and in the same way like the story behind the creation of the Brompton: seeing the potential behind the concept of folding bikes but being not happy with what's available on the market). Regarding the cleanness of the design it reminds me a bit of the castro bike (though the Iruka is obviously much more complex).

The fold does not convince me too much on first look: Long and flat (like a folded Tikit) but surprisingly wide and I cannot find an advantage that would result from using a mono fork (apart from looks). I guess it all depends from how it rides.

Thanks for sharing!

Interesting looking bike indeed. Wouldn't mind checking one out when they go on sale next month. I suspect that like Tyrell bikes the Iruka is sized for the locals, so a bit small for anyone taller than about 170-175cm.

Iruka means dolphin... so maybe the black knob is a design feature to match the name?

Indeed! The max saddle height of 950mm would be by far (!) too low for me In combination with the pedal being ~10cm off the ground in lowest position, the max. bar height of 980mm is 5cm higher than the S-Brompton and 5 cm lower than the M-Brompton. Would be rideable for me, but not with comfort and only over shorter distances. So it seems you are right regarding the bike being a bit on the small side for Europeans.

Nice to see new designs but see some issues with this.
Wide fold, tiny roller wheels and the grip is so close to the ground when folded so would probably dig into the ground with just a few degrees of tilt. Trolleying this folded would be very difficult.
