Hi guys this is my first post just looking for some tips in general or any advice really,

I have been looking for a new hobby to keep me busy and was thinking about building a land yacht to take to the beach every now and then. I am fairly handy and have plenty of space/tools to build it so hoping it will be a fun challenge. Was thinking of making it with mild steel for the frame but unsure about what would be best for the wheels on the sand? so some help for the wheels would be great. And was also thinking of putting in pedals? It will be probably be basic in terms of the body/shape and mast etc.

So really just looking for any pointers or advice from you guys to help me get going?

Thanks in advance for any help.
