Assembly Instructions

Congratulations on your new SE Bike! SE bikes ship partially assembled from the factory. We always recommend that a trained mechanic build your bike, but if you follow this guide and take your time, you can build the bike yourself. Always ask an experienced mechanic about any steps you're unsure of.
