Don't loads in the front affect steering? Even my suspension fork alone causes the front wheel to sometimes turn into unwanted directions.
I have put many hundreds of miles with Lucky Dog in the front Wald Giant Newsboy basket using different types of bikes including a World Sport. He weighs in at about 20 pounds plus the weight of the basket.
And it does affect steering!!!! You really need to pay attention, have good core strength, and plan in advance.....and I would never use it on the roads.
Dog loved to ride and his ears would flop out like wings when we go up to about 10-12 mph.
Once got up to 20-25 mph on a down hill section of a mup using the dog in a basket on the World Sport but I quickly realized doing this on a 27 1/4 wheel on crushed stone path was sheer stupidity.
Unfortunately Lucky Dog (not so lucky) went blind and he is fearful of riding so don't use it anymore.
