Hello i am pretty new to eurobrick and am wanting spme advice.

I breed dogs and have sold some recently. I am planning to get a sian and buwizz 3.0 with motors, and want to motorize it fully(including the gearbox) and need some advice. Thanks

Hi & Welcome!

Have you considered breeding cats as well? They seem to be more popular on the internet.

Are you sure you want to motorize the Sian? By keeping the gearbox, you need to find space for the electronics in the cabin space… and obviously: by keeping the gearbox you should come up with a motorized clutch as well – which will cost you a lot of space and power.

And getting even more meta: the gearbox is a device that is not necessary in an electric vehicle (unless you want to have ONE SPECIAL gear… in an off-roader: ultra low range… in a speed-build: high-speed gear)… having more than two gears will only grow the death-count of molten parts by the BuWizz motors… which – to be honest – will never be 0… even if you get rid of all the gears.

Maybe it would be best if you could tell us what you are trying to achieve…

-          A super fast car which provides lots of fun racing it

o   You shouldn’t try to achieve this with Lego… unless you are willing to permanently change parts… not only axles and gears but also parts bearing them… unless you need to make videos for selling BuWizz-power-units this endeavour is not suited for Lego

-          An interesting and complicated motorized build with Sian-aesthetics

o   Keeping the gearbox will make the built very complicated/crowded and from a purely engineering standpoint a bit dull… because… why would you, when using electric motors?

o   Getting rid of the gearbox will give you the space to achieve at least a good-looking motorized car… but chances are: it’s either not as fast as it looks… or it will burn rubber and plastic

-          Something totally different?

Maybe. I think that i just want realism in a motorized build.

Thanks for the detailed reply:) this will be my first technic advanced supercar(is that what its called?)and my first try at buwizz and i have all the parts and motors needed to motorize it. I really dont know much about melting lego motors and stuff because i have never had fast enough electronics. Well thanks forthe advice and i am hoping to get the sian and order the buwizz + 2 motors tomorrow. Ps you should try breeding jack russells.

I also want to try to design a petrol cylinder system for lego, it would have more power and need gearboxes.

I have disassembled the sian and am rebuilding it with electronics. the drivetrain was not able to drive on 5 ~ 8 gears from the engine location. because of that, I am putting in a 4-speed that can cope. I am currently at the gearbox stage and am assembling the first half leaving room for some motors. the buwizz 3.0 is c

sorry for the reveal hidden comments, it was an accident
