As already mentioned, spending a ton of money on this bike is a bad idea IMO. You're much better off trying to find a new or used bike that already has the equipment you're looking for as this project could easily end up costing as much (or more) but you're still stuck with a cheap frame and other cheap parts, handlebar, stem, suspension forks, seatpost, brakes, etc., etc. Either give this bike a good tuneup and understand it is what it is or sell it and get something better. Also contact Canadian Tire for any warranty or free tuneups offered as many dealers offer this on new bikes only 2 months old.
