Pittsburgh's hills are famously steep. What is the proper technique for starting from a stop on a steep uphill?

1. Hold the bike with the front brake, ease the clutch to the friction zone, then add throttle and release the brake just as the clutch engages
2. Hold the clutch out and roll the throttle wide open
3. Use only the rear brake and slip the clutch the whole way
4. Coast backward briefly to gain momentum
