MOPED ARMY

If it is a smaller hub and not a crazy fast bike you could do something like this. Drill through the hub and use some stand-offs. Weld a tab to the lower leg and bam easy disk brakes

RUJOI Bike Disc Brake Kit, Aluminum Front and Rear Caliper, Full Aluminum Alloy Bicycle Brake Lever, 160mm Rotor, Mechanic Tool-Free Pad Adjuster for Road Bike, Mountain Bike

I used a setup like this on my hobbit. With the cable brakes it stops pretty well. Somewhere between really good drum breaks and pit bike style hydros like Joe posted. People say your going to warp that rotor easy….your not going to stop well…..the pads will wear out easy….bla bla bla. Don’t knock it until you tried it. It has lasted for years and I just now should probably change the pads…I mean Jake uses MTN bike hydros on Toby?!? Fastest bike I have ridden and stops amazing.

I will say that the link that Joe posed…That setup is way superior to MTN cable brakes. My bike with that style of brakes will toss you over the handle bars if your not careful…..but hey MTN brakes is just another option.

Yeah that's such a smoking good deal... Haven't had a chance to use them yet but they look super nice, sealed bearings too.

Not sure if the axle width's on front and rear wheels are same, but if so, you could probably make an adapter to where the sprocket would go and put your disc there

I've gotten new spoke wheels with the sealed bearings in them, they are nice and fit perfectly. They take a 12mm axle though so you need to modify your stock forks to make the axle fit. Takes 2 min with a file. But that treats front disc combo is probably the easiest option

Thanks for the many ideas! I am currently working on using a 80mm pulley from Mercedes as a adapter for the rotor.

Ftfy. Definitely done this to almost all of my bikes, haha. I use long 12mm bolts and machine custom spacers for all the bikes I convert to sealed bearing. The first bike I ever did it to has been on the road since 2006.

those tomos axles work literally PERFECT in the ebr hydros or stock maxi forks without any filing & are the right length. you can even reuse your axle nuts & washers, too.

but i guess i’ll if you wanna file…go ahead & file. i can’t stop you even if i wanted, but thought of filing the dropouts unevenly & the axle being cocked & the misalignment causing brake plate/caliper spacing issues & uneven loading between stanchions is enough to give me an aneurism. i’d rather let the factory handle alignment things like that.

& again, i know “it’s just mopeds” but it seriously doesn’t have to be. it can be done right. it can be perfect. there’s no need to cop out or pass on any of these “solutions” just because it’s what you’ve done & had “work” in the past (edited)

Love the look of that disc, timeless design. What is diameter and thickness of it? 220?

And, if not secret, what heat treatment is did to it, if any?

Yeah these are nice, speedo drive is not an option on these
