Disc brakes for motors without them.

[wesnewell]

If your motor doesn't have a disc brake adapter, but does have freewheel threading on both sides like rear yescomusa motors. This should/may work for you.

There's also this kit, which I think is complete, but since I use rim brakes, I couldn't say for sure.

I ended up having to add a few washers between the disc brake and the adapter in order to get the disc brake to line up. Works decently well. I'm curious if the Leaf bike one would fit better though... hmm

Kind of off subject sorry, Ken what was your top speed with the stock controller and what are you hitting now with the 72v? I have put 700mi on my yescom 1kw since july,love it, love that strong steel rack too. I actually have it on the same bike you have too, been working out good even with 54lbs of sla on the rack , actually handles better than I thought it would.

I have one of these adaptors, they are very good, due to the thickness of this adaptor it will fit pretty much any brake callipers without touching the motor cover and the bolt holes will allow me to fit IS or the Chinese bolt hole configuration. A word of warning about the price though, even though it says $18 on the sale page, by the time I got to the checkout page the price had risen to 48 AUD. Delivery was swift, about a week from China.

I bought one of these kits years ago, they are rubbish, don't bother. The piece that holds the calliper is quite soft steel and bent inward when I applied the brake. The calliper itself was the worst I ever tried with bugger-all braking power.

That looks like a good screw on disk brake adaptor. I bought some once that were very cheesey, and they didn't work since they immediately stripped the motor threads. Others, thick aluminum ones like the one you show have worked fine for me.
