Bicycle travel · Russia

Hi, I’m looking for info on doing a solo bike trip from Chelyabinsk to northern China via Omsk. What’s the best time of year to go? Can I do it staying only in hotels and restaurants—without having to haul a tent, stove, etc.? Also, is there a border crossing point in northern China, because I can’t find anything on Google Maps? What’s the road condition like? Thanks
