Am a long time rider over 25 years. I used my mountain bike all winter. -25c below 0. no problem at all. i was cold bout it. I do have many ideas, tips and tricks so dont be shy to ask me for any advice. the last two projects are still riding strong. Can see the 2 bikes good there. The lowrider is my favorite...fricken blast to ride...very fast. I am setting off trip from Whitehorse to Inuvik and return...Dempster Hwy. prob middle of june. taking the mtn bike for a burn...and running a straight pipe on the mtn bike now. going over the mtn bike fine tuning it. thats it for now.
