I'm a totally amateur bike rider. I want a new bike and like the looks of the Electra Townie 21, and the Electra Townie 7D. The description on the first bike says...'Shimano Tourney 21-Speed'. The description on the latter bike says...'Shimano Tourney 7-Speed Derailleur'. Besides the number of gears, what's the difference in the derailleur system, or whatever it is? Is one better than the other?
Also, if you have any knowledge of Electra bikes (good or bad) please enlighten me before I make my purchase! Thanks.

For what you want to do as an amature rider, the Electra should be fine. I know several people that have them for cuising on paths, etc..., and they love them.
The 7 and 21 are the same thing. The 7 speed refers to the number of gears the rear derailleur (the gears on the back of the bike) has. 21 refers to the gears on the back of the bike (7) multiplied by the gears of the front derailleur (3 - on the front of the bike) to give you 21 gears -- although I should note, you can't use all of the gear combinations.
Go to a store that sells Electras have someone fit you on a bike and ride it around the parking lot. If it feels good then buy it! No, it's not the best bike out there, but for starting out and figuring out what you like/want in a bike, it'll be fine. If you try to go too high end you could very well wind up with 'too much bike.'
GOOD LUCK!!! RIDE AND SMILE!!!!

Well.. I think that both are the same but marketed different.
Usually general use bikes have 3 speeds up front, and from 6 to 9 gears in the back. And you make the multiplication for the number of gears. A 21 spd bike usually has 3 front and 7 rear.
But, since it's the same brand, maybe on the 21 model it has 3 speeds up front, and 7 in the back, but the 7D might only have a single speed up front and 7 in the back.
If that's the only difference between both bikes, you should consider is where youre riding. If where you live is mainly flat, you could do fine with only 7 speeds, but if you have some hills, 21 would give you more range to climb.

One bike is a seven speed and one is a 21 speed. The difference being that the 21 speed has three cogs on the pedal crank in addition to the 7 in the back.
These bikes are recreation bikes, intended to be ridden for light exercise on nice days. They get tons of style points, and you'll look good riding them, and they _are_ comfortable. It's a wise choice for someone to get as a casual cruiser. Not good for commuting or long distances.
Neither one is better or worse, but unless you live in an area with alot of hills or plan on riding dirt roads, go for the 7 speed. The gear ranges are wide enough to handle small hills, and there's less stuff to worry about learning or fixing. As the cyclesnob above noted, Tourney is shimanos bottom of the line, but so what? If you like the bike, and it's comfortable, and you can afford it, get it. Don't get pressured into spending more money on a bike you like less, but by the same token, don't hesitate to spend more on a bike you really like. Spending money on a cheap bike that you don't ride is a bigger waste than spending more money on a bike you will ride.
Buy what makes you smile, and have fun.
Ciao, Bella!

The above answers have adequately addressed the difference between the 7 and 21. I would offer this bit of advice however. Look at the Townie with the internal hub. It may cost a bit more, but it will decrease the maintenance on your bike and makes changing gears easier.

The Tourney is Shimano's bottom end derailer, and it's an insult to the Shimano name. It won't hold up to serious use. The bikes you're talking about are NOT for serious riding. If you want to do serious riding, go to a bike shop and look at their road bikes.

the backside bracket could contain sealed bearings that may't be serviced, you may in basic terms replace the cartridge. examine the links provided in the different respond, and you will could desire to purchase the mandatory kit, there are diverse ones for whichever backside bracket that replaced into put in on your bike. Trek replaced into no longer the producer of the backside bracket, they purchase those factors from yet another company, so which you may desire to discover out which make and sort backside bracket you have
