They had that bike on sale for $300 off (plus some accessories thrown in) during June, and now $350 without the extras. Given that now is the height of the riding season peak demand, I'm starting to think they're having trouble moving that $2k bike out of the warehouses to be forced into deals like this in June/July. It's certainly a better value at that price.
The Rover's hydraulic brakes are probably a welcome improvement though (haven't heard much feedback about that either way), but with the issues and design glitches (no way to kill the power with the key) in new models, and the downgrade from the Minis to the Contract5 (at a higher price, too), I'd be hard-pressed to choose a Rad to buy right now and would be scrutinizing the competition a little more closely than I did when I bought my MiniST2 15 months ago. And the semi-integrated battery models will be a bear to mod / hotrod, not just getting to and changing a 25-cent fuse.
I treasure my Mini; it was just the perfect one for me, with original-spec components and a fair price.
