why do we need to reduce friction?
A) Stand over height for that model is 78.6cm or 30.9 inches. You want about an inch to 2 inches of clearance standing over the bike. With your feet spread apart about shoulder width, measure from the floor to your crotch - snugly. D) Frame size: Probably being the key word. Remember - the final decision is yours. You can NOT test ride a bike sold online BEFORE the sale. You can from a real bike shop.
go to a bike store you can;t get anything decent at walmart or target or online, unless you can also assemble and tune it entry level road bikes are pretty good i happen to like fuji others will all be in the same ball park of goodness at a given price 400 isn;t enough really you could get a hybrid MAYBE on sale sizes vary, unfortunately one company;s L is another;s XL even the numbered ones, 54cm, 56cm, etc are not standard you probably want 58 cm in a road bike but you ahve to try it bike stores will get you the right size there are no special ''weather'' or ''outside bikes'' any bike in that range will have quick release wheels wle
Consider 2, maybe 3, essential accessories in addition to the bike. A front-facing white light and a rear-facing red blinkers are musts if you anticipate riding in the dark. Getting hit by a car would suck and besides it's illegal to ride without in most places at night. One ticket is more expensive than the lights. The second is a good lock. Don't be cheap here. You don't need the most expensive lock money can buy but you want to deter thieves. U-locks gt; cables. Try to get a little nicer lock than the other bikes parked near yours. Simply not being the easiest target of theft will help. And last is a helmet. I don't use one riding around town but that's your decision. A trick with lights: rear blinkies are hard to improvise, but I've duct taped or Velcro strapped $1 mini-mag lights to my stem. Lot cheaper than front-facing bike lights and it'll work. Try to take lights inside with you or they will be stolen.
Sounds like the car may have an after market security system installed. If that's the case, you'll need to contact the manufacturer / distributor on their company web site and get some assistance. They may have even got an owner's manual that you could download.
It depends on the size of your lenses. The larger the lens the thicker they will be on the outside edge. That being said, the 3.25 is getting a little thick. I would go for the hi index with anti-reflective. This will ensure they are the thinnest and lightest and will be most attractive. If you want to be really cheap, get the poly with the AR. Poly is thinner than CR39. No matter what, get the AR. It is well worth the money. It looks better and you will see better, too. Do you wear contact lenses? If you do, and you don't wear your glasses often, then go the inexpensive route if you want to. If you want to have a really nice looking pair of glasses then do the hi index with AR. No contacts and wear glasses all the time, do the high index with AR.
