Those Rivian and Defender bikes are pretty awesome...

Can it be a monowheel ...with spare tire wheel? 

 

Sorry, could not resist asking this but I don't regret anything...

Just wanna chime in that you dont need to base the model on a fancy real life motorbike to make it appealing. A fellow from my country (https://www.flickr.com/photos/khanglego) built this. 

The real motobike is common as dirt in my country, but the model is stunning nonetheless.

I believe this to be the worlds most popular motor bike?

LOL I think same thing. BIG front wheel with seat inside and very small stabilizer wheel on back.

I have some inspiration

I'm not a Technic builder, but take the challenge to build a motorcycle!

[amorti]

I'm not creative enough to actually make a model, but if I did I'd cheat a little by building a Honda Grom or Monkey 125. You could build to a bigger scale and have more details, if the standard bike wheels are acting as 12" instead of 17". 

The Ducati rear tyre looks a similar size to both front and rear tyres of a Grom.

The gold Ducati shocks would also be a good match.

No cutting, sculpting or modifying parts.

My model is using 6.5L shock absorber with hard springs and light blush grey housings. Is this legal? I don't think this combination was used in official sets, and mine are made from mixing parts from hard and soft shocks. I can switch to yellow housings if necessary, but the grey looks better.

Are there any limit on tire size? 

This one?

There is no dimension restriction.

Note that we need to have a model of a two wheeled motorcycle. The one on your picture (and others similar with maxi wheels) requires additional wheels to keep it stable and upright.

Those were for reference. I was thinking maybe using these:

instead of the cycle wheels. I can use the motorcycle wheels if you want.

[Seasider]

In my opinion you can use whatever wheels you want for this as long as there’s only 2, they don’t need to be the official motorbike ones

[Jim]

There are indeed no wheel type limitations.

[Ngoc Nguyen]

I'd love to see someone build these.

It looks like this question I asked the other day might have been missed, so I am going to bump it. I hope it's not a problem.

I'll tag @Jim and @Milan, that should get you an answer...

If you mix various LEGO parts, it’s okay.

Ok, thanks. I thought it might be an issue because it required disassembling factory assembled parts.

Unless you start sawing etc, you can use the LEGO parts how you see fit.

Hi @Jim   

Could i get a bit of clarification to the rules. 

Was hypothetically thinking about doing a 3 wheeled bike but with the configuration in the pic below.

The question is, if the rear tyres were to remain where they are now, but instead of the two rear swing arms being joined, having them being independent instead. Then hanging a sidecar off one swingarm, (the wheel attached acting as the sidecars wheel), then having a rather large panier off the other swingarm, to balance it out, would that still fall within the rules?

[Jurss]

I think it was discussed in beginning, that it is not allowed, third wheel can be only on sidecar, and motorcycle should be able to drive also without that sidecar.

You're indeed right, (just had a second look at the rules on page 1).  But at the same time, what's stopping me from making one of the swingarms and attached wheel + sidecar, completely detachable?  Sure it would look really really strange, and the panier would have to be fairly weighty to compensate the obvious offset of balance, but technically, that should still fall within the rules, shouldn't it?

Have You heard about fair play, and just have fun of the contest?

I don't see how it can be classed as a lack of fair play really.  Please bare in mind this is my very first attempt at building a design out of LEGO technic, so my skill level is way far below the likes of yourself, and other established members in the Technic forum.  I'm just merely exploring/exploiting what little creative talent i have. 

However, if you feel my hypothetical interpretation of the sidecar rule is going against the spirit of the contest, and somehow taking the fun out of participation, then i'll pursue it no further.
