    1. Shipping was pretty fast I ordered the engine on May 24 for 169 dollars with free shipping. I got it on Wednesday May 31. It's estimated arrival was June 1 so it got here early. None of the parts were missing, it does smell like it's been used. It did not come with an instructions manual.

    Unboxing the Roadmaster GranitePeak

    I originally brought this bike already assembled by Wal-Mart for 78 dollars plus tax. Within the first 24 hours, the bike wouldn't shift down into first gear. One the second day the handle bars slipped. I read reviews about it being a good bike so I returned it and decided to assemble it myself.
