You can get a lot of bike for $5K, but most of the big OEM's, where you can spend that much money, offer pedal assist (PAS) only. Your best bet is to see what others are using especially if there's a local shop. Don't know the current laws in NYS and/or NYC, but you might want to check. Be careful of the "reviews" you encounter since some individuals are compensated for them. A light bike is another aspect that's going to be a challenge. You might consider DIY.
