Most often tingling or numb hands are just a sign that there is too much weight on your hands. However, it can also be caused by clsoing your glove velcro straps too snugly. This happened to me! I found I had to adjust my gloves straps VERY loosely in order to not get tingly hands. Just one little thing to check.

Here's another couple of thoughts-
-Be sure to wear BRIGHT clothing so cars will see you better.

-Do not move over so far to the right that you are afraid of catching the pavement edges with your tires and falling. Drivers and other cyclists are more experienced than you and they'll have no problem going around you. If you are wobbly then leave at least a foot between you and where the pavement drops off.

-This last tip is weird but true. Studies have shown that when cars pass bikers on the road, they give a wider safety margin to bikers dressed in such a way as to be obviously female. Long hair, bright flower prints, pink helmet, a jersey that doesn't cover up your shape, whatever. Seems that drivers associate feminine looking bikers with irratic or beginner biking skills, so they give them a wider berth when they pass around them. It's unfortunate that things are this way in our world, but there you go, and as a terrified new rider you could use this to your advantage until you gain more confidence on the roads.
