AgentRick Posted January 2, 2009 Posted January 2, 2009 (edited) I was thinking of picking up some BBB wheels for a Moc or two I've been working on, but I'm having trouble deciding what wheel size I should use. The engines I'm trying to make are the BR 24 and the BR 81. Could anyone with experience with the small, medium, and large wheels show a comparison between the standard 9v wheel and if possible the 12/4.5v wheel? Hope I'm not asking for too much.

simonwillems Posted January 2, 2009 Posted January 2, 2009 Hi Agent Rick57! Coincidentally I made the BR24 with the large wheels from Big Ben Bricks and I think it turned out good (look in my signature). The middle sized wheels are relatively new to BBB, so most of the trains you see on Brickshelf and Flickr are made using the larger ones that have been around longer. I have not yet compared all the wheels, but I can say that the small BBB wheels are the same size as standard 9v Lego wheels, as can be seen here. I hope this helps a bit, good luck with your project. I know from experience that it can be hard to make a suitable mechanism to connect the six wheels, but that is a lot of fun too. Quote
