Wanted: disk brake compatible fork for BikeE CT

[ivor]

Hello, my Bike E CT 2.0 will have an Ecospeed electric assist soon, and I'm thinking about upgrading to disk brake in the front. Apparently I'd need a stouter fork with the caliper mounts but NOT the suspension. Does such a fork exist and anyone have any leads on where I might get one?

Thanks
