Monarch springer fork and drum brake - Motorized Bicycle

Does anybody had installed a drum brake paired with a Monarch Springer fork? I was planning to but a Monarch springer fork but since the shock moves the entire front end I am not sure if the brake can handle this. Thank for the suggestion and advise.

Here is the link of the Monarch fork.

Yes it will fit, I had to spread my original set slightly to make it work. Keep in mind these forks were designed for a bicycle, depending on how much weight your adding to your bike might make a difference on the operation of the fork. My bike is pretty heavy and the springer really does not operate as it should, I'm looking into adding a different spring set up or a helper spring to the original.

Thats a good question... Considering how the fork travel works, I think it would work better on the front leg; but the rear leg is stronger.
Maybe you could make a simple small swiveling bracket that attaches to the rear leg?

It needs to move with the wheel, so it goes on the front (action) part of the fork.

the arm will need to be strapped to the stable leg (doesn't move with fork's action)
on a monarch type, I believe it is the front fork leg
on a bee-hive type it is the back one
hope that helps

This might work.

I have a Worksman front drum wheel on a pair of Crossbow/Monark forks.
I don't have a pic posted anywhere now, but I just cut a notch in the drum bracket that straddles one of the bolts I used on the fork linkages. Getting the front wheel back on is a bit of a task and the drum brake sits at an odd angle but it works just fine.

I bought mine a couple years back, so I'm not sure what they're shipping now.
The forks had problems in the past--the front dropout spacing was too narrow (about 90mm vs. 100mm, which is what MTB wheels use now) and the head tube was too narrow to mount regular bearings (had to use a shim under the lower head tube bearings, shim not included).

....The 90mm axle spacing leads me to think that they were originally set up to fit true vintage bicycles (those using 1950's-era wheels) but a number of people complained so they might have "modernized" those aspects of it.

I also had to use different bolts; the ones as shipped would not work with the lower linkages "flipped" outside the lower fork ends, and the bolts only had a single nut and so wouldn't stay together anyway (the bolts were cut just long enough for one nut, so you could not screw another nut on against the first).

Would the piviting drop out need an extention added reaching up to hold the brk drum support arm so that itwill pivit with the axle
