Thnx for the replys guys. The correct spoke length for 2015 stock front wheel is 145mm.

You guys are right i bet by adding the ez wheels i would be better of than crossing the spokes. I wanted to ask cause bromptons have many little tweeks. For example im debating using brompton ez wheels, or 3rd party ez wheels, or the offset skate wheels.
The bikes at the shop, so i cant take pics. But i think the spokes get hit, while on trolly mode, when i turn the cart twisting the handel instead of pulling up and swiveling the little wheels.
