I'm on the lookout for larger roller wheels for my Brommie. I like to use my bike for grocery shopping, as an example, and being over 6 feet tall, I don't like to have to bend over while wheeling the Brommie around the store. So I was wondering if anyone knows where I can get larger wheels that will elevate the bike while wheeling it around? For that matter, will larger wheels (in diameter) work and not interfere when folding.

Thanks
Wayne
