General Part Discussion

I counted ~64 teeth on the gear. Could be just 60 though to match existing gear ratios.

Shouldn't a 60 tooth gears have a diameter of 7 studs only, based on the turntable's size? That gear looks wider than 7 studs.

The 60 tooth turntable is 7.7 studs in diameter. But as others have also written it's most likely 64 teeth then.

Also, why is that bike not a Technic set... 

Because it's build of a system parts. But I wish they produces some MTB from Technic

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

~30 stud wheel/tire is enormous, might have some interesting GBC applications depending what it looks like under the tire.  I like how it uses 12 spokes so it can just go onto a pair of the classic pulleys turned so their holes are 30° different.

All I see is something that could have been the next 1:5 bike for the Technic lineup :(

I am definitely counting 64 too. Exciting times!

[gyenesvi]

Wow that's unexpected but interesting. Are the spokes 16L links?

I think they are string with stud on each end

Well, I'll certainly have many uses for this in clocks. If I counted properly, it has 64 teeth, making easy 1:8 and 1:4 gear ratios possible. Please make 32t gear next XD

64 teeth sounds plausible, but could this be a 60 tooth spur gear instead? Because remember, even though we later got a 60-tooth turntable in 2015, we were originally supposed to get a 60-Tooth Technic Spur Gear for the Super Cycle's back wheel in The LEGO Movie 70808 set, but LEGO canceled that part at the time for cost reasons and used a 40-tooth spur gear instead. That being said, a 64-tooth spur gear would be more desirable as it could allow direct gear ratios with other existing spur gears.

I can count 16 teeth on one quarter of the wheel. Also, it seems slightly larger than 60 tooth turntable. 64 is definitely more desirable in terms of adding new gear ratios.

Fortunately, the new bike elements appear to be Technic parts, which could be a signal that a LEGO Technic bike-related set using these same new elements is also on the horizon. I know that's a conversation for our Future Set Wishes and Speculation topic, but we should definitely keep an open mind that this may not be the only time we see these parts used.

Agreed. Then it's settled. Looking forward to seeing what's possible with this new 64-tooth gear piece.

If I counted correctly the spokes are 11L and the whole wheel is ~33L in diameter! That is bigger than the largest (Hailfire) wheels ever made by TLG, which were 26.5L (21.2cm).
And the gear is 8L so definitely 64T.

Wasn't the Lego Movie one a 48T gear? That's my memory of it, at least

Which means there's no way in the world that those new wheels are one-piece molds. In the very unlikely (and extremely unfortunate) event that they are, they would be ludicrously expensive for LEGO to produce once—let alone twice, for each and every Road Bike set that rolls off their set assembly line. Plus, they would also be very expense for us to buy individually off of Bricklink after this set is released, so we better hope that's not the case.

Assuming that my hypothesis is correct, then those vertical lines we're seeing on the bicycle wheels are highly unlikely to be mold lines—I wouldn't be surprised at all if those are separate, smaller curved connector parts which join together with short pins or axles to form that final circular wheel rim shape which the large single tires then slip around, in a fashion similar to how the large circular gear racks, originally introduced in the 42055 Bucket Wheel Excavator set, came in quarters (i.e. the 11x11 banana gear elements). If so, that would also explain why thespecial new spoke elements are needed.

No, it was definitely 60 teeth, I believe.

The wheel has to be smaller than 30L to lift off the ground because the stand is 20L on each legs. So my bad for earlier.

@HydroWorld Outlook The tire is one piece, but I agree, that the 12 arch segments could be halves that connect together to form a larger wheel.

Ah, you're right! I feel less regret now, since 48T would have been more useful:

Ah, okay. Regardless, however, the complete wheel assemblies in this new Road Bike set will certainly, easily surpass the diameters of the largest single-mold Technic bike wheels from the BMW motorcycle set, along with the diameter of any wheel we can currently build today using 11x11 gear racks in groups of 4 (as was done on the bicycle MOC shared previously). That fact alone means the wheels of this road bike set will still be among the largest-ever LEGO wheel assemblies we've seen in a while, with parts enabling even bigger wheels still possible in future sets.

The wheel does look like it's made of multiple pieces to me... maybe something that connects together with axles like the "macaroni tube" pieces.

I thought the tire is just plastic, and is part of the wheel mould? but yes, it appears to be in sections/

I can't wait to make other lego bikes now!!

Precisely! That's exactly what I was talking about.

The tire is probably rubber. And I can't wait to finally, after all this time, have more suitable parts to construct an aerodynamic shroud for a large ducted aircraft propeller engine—plus have a new way to build a rim-driven thruster with blades larger than what is currently accomplishable today with the existing 3250 and 77107 circular ring girder elements. Oh, and here's a really good one—a larger flywheel to run pneumatic engines with.
