Redrover, congrats on the new bike! Sounds like you are doing great so far with the gear you've purchased. I ditto what some of the ladies have said about the bike shorts. They make the riding experience so much more comfortable and if you don't feel like bearing it all in spandex right now you could wear some thin shorts over them.

As far as starting off goes, I find it helpful to have my feet in the right position. With one foot on the ground I put the other one on the pedal at about the 2 o'clock position (right foot) ready to produce a downstroke. This allows for propulsion from the standstill and then you can get the other foot on the other pedal.

For stopping I usually come to almost a complete stop, lean the bike slightly to usually my left side and put my foot down. I think people probably become used to using the same foot to stop and start on while riding. You just have to work out what you are comfortable with.

Also, I'm not sure what seat the Navigator comes with but don't hesitate to get another seat if the stock one is hard on the tushie or girlie parts! Good luck and enjoy that new bike!
