What mountain bike would be best to buy in bulk?

I am uming that if you want to buy this many bikes that you run some sort of business. As such, you could probably buy bikes direct from bike distributors, byping the retail level. Most companies either import bikes and distribute to stores, or have an arrangement with a company in your country to distribute bikes for them, since Canada is a much smaller market than the US. You simply have to contact the bike company directly to find out about how they distribute their bikes in Canada. You would, of course have to be able to emble and service the bikes yourself.
