After much deliberation, and many discussions with Nick from Carry Freedom, I’ve ordered my trailer. It’s based on a Y-Frame Small, and has a Zarges K470 lockable shipping box on it. The tyres are Big Apples, and it has stainless steel axles and much stronger hitch where it connects to the bike.
I’m pretty excited, and can’t wait until it arrives! I’ll post a full update on it once I’ve got it and taken it for a few rides.
