Disk brake retrofit for BikeE AT?

[izgod]

I'd like to know if I can upgrade my BikeE AT to front disk brakes. I know the RX came with disk brake on front. As far as I know, it's not possible on the rear because of the internal hub. Has anyone done this? Is it even possible? Any help/ideas appreciated.
Thanks,

John

About the only disc brake install requirements are;

1. Fork w/caliper mounting tab(s) (IS 51mm prefered)
2. Six bolt (IS) disc compatible hub laced to your favorite rim
3. Disc brake assembly

On a 20" (406mm) wheel, I would suggest a rotor diameter no larger than 140mm.
