General Part Discussion

I'm afraid, it started as technic, then they realised, that it doesn't look so good, and made better looking frame from system piecies.

Well the good thing about LEGO parts as that they can always be reused in future sets if a legitimate purpose is found for them, so just because a LEGO Technic bicycle or tricycle isn't here yet doesn't mean one isn't coming in the future.

Again, that's a conversation for our "Future Set Wishes and Speculation" discussion topic, but still, the fact that these new parts are Technic, along with the brand-new 64-tooth spur gear (which we will almost certainly see again—imagine the possibilities with a part like that!), is a strong signal that LEGO's designers are preserving the possibility of using these parts again in future sets.

In the meantime, I am looking forward to that Road Bike set coming out and I will be keeping a watchful eye on it.

Yeah, even a dedicated piece like the Volvo XL bucket in 42030 gets a second use.

Precisely. So let's just keep an open mind about the new parts, and we'll see what happens after the Road Bike set is released.

Yet another transparent color for the 11x11 banana gear rack and there are freaking 8 of them in this set.

Which set is this? A licensed fantasy playset? A nonlicensed Monkie kid set? Either way, this is awesome—good find!

The more translucent/transparent quarter-circular gear racks that appear in any particular set, the more common these parts become and faster the costs of these individual parts drop for the rest of us. In this case, it looks like we can now build mechanical sculptures using water tiles and have these new, recolored banana gear racks blend in.

Or, even better (myself and many MOC builders out there will much more strongly appreciate this application), we are now able to build large, circular ion or plasma engines for massive futuristic submarines, spacecraft, or transmedium craft models (like my upcoming hydroaeroshuttlecraft model) that we can run standard LEGO LED lights through and power/illuminate, since these gear rack elements are transparent, or at the very least, translucent, meaning some light can pass through them.

We can also, theoretically, employ and incorporate these parts into anti-gravity acclivity rings for larger futuristic vehicle MOCs (again, like my upcoming hydroaeroshuttlecraft model), driving these complete rings with custom turntable assemblies (as is already done in the 42082 and 42146 sets) or use toothed pinions (gears) to spin them, all while still installing standard LEGO LED lights to shine through them for extra effect.

It's from 80120, which was just revealed today.

Ah, I see. This is a nonlicensed Chinese Lunar New Year set—Prosperity Carp Leaping (80120). That's a really clever use of those parts, actually—really good use of Technic to achieve that visual "jumping out of the sea" effect. And surely enough, it's a hand-cranked, continuously-rotating fish sculpture with water in it—just like I mentioned as a possibility in my longer post above, so that's one application validated.

However as I also explained above, other valid potential applications for these new recolored banana gear elements include ion propulsion and anti-gravity engines on large futuristic craft/vehicle MOCs or even future official set models.

If I counted correctly the spokes are 11L

If they are like the 16L link pieces, but shorter, then that's really nice to have, I've long been waiting when TLG realizes that it would be useful in other lengths as well.

I also wonder about the pins that mount them to the rims. They don't seem like 3L, would seem too thick, more like 2L, but then it can't be a regular 2L pin.. secretly hoping for a 2L version of this

By the way, the rims definitely seem like built from a bunch of curved segments.

They are likely 11L spokes based on what we're seeing, and I agree that they could be similar, in principle, to the previous 16L link elements. However, I do believe that the actual spokes themselves are too narrow in diameter to be axles—they are likely specialized bar elements instead.

That would be great! A 2L pin that can lock itself in place—at least at one end—would have countless applications outside of this new road bike set.

Yes, that's what I said initially—there's no way in the world those giant rims are one-piece molds for that size. They most likely connect together like the circular macaroni parts, with pins and axles to reinforce their connections, to form that final circular wheel shape.

The big black tires—which we know must be a single large rubber (or less likely, plastic) mold for design reasons—then slip around those completed rim assemblies. That's the only conclusion that really makes sense for a large official LEGO bicycle model of this size.

That's why I made my own. Sick of waiting for LEGO to bring out something like this:
 

I've also build probably one of this 10  years ago - it was nice :)

Wow, not only a great recolor but that looks like a really nice set, and not absurdly expensive.

I'm pretty sure it's half pins, with the spoke and wheel parts both being half-thickness pinholes.  They mount alternating sides.  I can't tell if the wheel piece is symmetrical or if it's also offset to one side so that the two together create a 1 stud thick "beam" shape centered on the wheel.

This set has 3 new recolors in purple

1x1 beam and 1x1 pin with pinhole

oh and the macaroni elbow piece

Indeed, those are also possible. The offsetting would also make sense, to put less stress on the spokes, which need to bend outwards.
