does the handlebar basket just latch on to the rack?
Ok, so Wald makes several types of front baskets. The one that I have has a bracket that gets mounted to the handlebars permanently (you can remove them, but they aren't means to be removed like their quick release mount), and then the basket latches onto it.
Here is what it looked like after I installed the Wald mount:
It was a challenge to make sure that I could still have a functioning headlight and camera with the basket installed, so I also installed a handlebar extender to lift those up, and a bike light mount on the front rack. Since then, I've learned that you can get a clip-on mount for baskets that will hold the light, but I'm not sure if they use the same Garmin quarter-turn mount as my light, so...
But... I found that the Wald mount interfered with my regular handlebar bags (Arkel Signature BB and BB packet), so I've strapped some horizontal tubing to the Wald mount, so those handlebar bags can mount better without excess rubbing. I can remove the tubes very easily for when I need the front basket.
This particular bike is pretty busy, but it's an AMAZING utility bike! I've also added a frame bag for added carrying capacity (mostly for extra straps and tools), a top tube bag, and it now has double feed bags attached behind the handlebars for quick access to snacks, my powerbank, compact camera, etc.
If I had only one wish, it would be that I wish I went with a front rack that has a platform. My front rack is a low-rider, which is great for stability, I won't lie, but I would have made use of a platform.
One final mention. When I strap a basket to my rear rack, I tend to add a cut piece of 2x4 under it to give it a few inches of lift off the rack. This makes it easier to get the Arkel panniers off (and back on). It's not necessary that I do that if I plan to use only the rear basket.
Let me know if you have any other questions, and I'd be happy to help!
