Voytek™ -- The ultimate hardtail mountain bike for plus and fat tires
Two shipping options are available during the checkout process:
1) Free shipping. This is a frameset and all parts needed to assemble a complete bike. Significant time and mechanical skill is needed to build the bike.
2) $120 shipping. This is a bike that has been fully assembled and tuned by Otso technicians. The bike will be partially disassembled for shipping (wheels, handlebar and seat post removed) but can be fully assembled by a home mechanic in 30 minutes or less.
