Re: More power!
Before you start making the bike faster, make it safer. Too many new builders spend time and money trying to get more speed and power when they should be looking at their brakes, bearings and frame integrity. Make sure you can stop the bike before making it faster. Assure the bearings, rims, spokes, tires and especially the brakes are up to the task of more speed.
Remember. It's a bicycle, not a motorcycle.
