I haven't bought myself a bike in nearly 20 years but old football injuries mean I need to keep my knees moving.

I'm happy to pay around $1000, possibly a little more, and am considering hardtails rather than road bikes because my son will likely use it as well and we live rurally.

I'm 6'5 so only XL or XXL frames and I'd prefer 29" I think.

So far Bikebarn and Torpedo7 seem to have the best deals.

Does anyone have any suggestions on manufacturers/models at this end of the market ?
