Our first 650b bike. Currently going as the Samurai65. We have some testing to do but it was an easy decision. After having explored the apparent boundaries of wheel size, and concluding that both 26 and 29 inch wheels are rad, going here is a no-brainer. Its been built for about 3 hours now and local trail and parking lot tests conclude that all is positive in the new world of 27.5" wheels. As shown, this bike is 26.9lbs. Some additional weight pending with a fresh coat of paint and real tires.
