If the chain was slipping, the derailleur probably needed an adjustment. The freewheel does not look worn to me

Ok interesting. Considering your current high gear of 14 tooth and 7 speed configuration, you probably have a freewheel system on your rear wheel, as opposed to a cassette, two different ways of mounting the rear cogs. You probably won't be able to get an 11 tooth cog that some have suggested on your wheels as it is. There are 7-speed freewheels with a 13 tooth high cog, which could give you almost 8% more top end if you need it, though, and they aren't too expensive. Those freewheels need to be replaced every so often, maybe swap it in next time you replace the chain. Swapping out the front chainring is possibly an option, but it is more complicated because of a lot of factors, and possibly not really a practical option for you without replacing a lot of stuff. (RD Chain Wrap Capacticy, Chain Length, Crank BCD, FD Max capacity and position, ask your bike shop)

I think that if you are really enjoying the fun and utility of riding, you could be well served by eventually buying a nicer bike. You will gain a significant amount of speed from a bike that is a little lighter and more efficient with some better quality parts, and ultimately for less money than trying to upgrade a lot of things on yours. The current sweet spot imo for price to performance ratio for a general purpose bike is around the $650-$800 hybrid range, with 9x2 or 9x3 gearing and probably disc brakes. You can probably eventually pick one up used for 60% new price if you keep an eye on local classifieds.

Upgrading it will be quite expensive. However, it'll provide you with a wealth of knowledge, frustration and, at the same time, fun.

Depending on your existing hub, you may or may not need a new hub to put your new cassette on.

With a wide enough range of gears on your rear cassette you can get away with a single chainring, so there will be no need for a new crankset/front derailleur/front shift lever.

As /u/fclbr said, you can choose downtube shifters in order to keep your existing brake levers. There are also bar-end shifters, and if you go for a single chainring, it won't be that expensive.

All-in-all, consider if this bike's right for you, size and geometry-wise, as your decision may be a bit rash. If it is, then I'd say go for it.

Rear derailleur - $20

Cassette - $20 - I recommend going for the 34t max sprocket. It'll allow you to stick with a single chainring

Bar-end shifters - $55 - they are 9-sp indexed, but they also work in friction mode, which allows you to freely adjust your gear

Downtube shifters - $14

Cables/outer cables are negligible costs.

This might work for you. Its smallest gear is 13t but does have a 28 T gear. They make a 14-34T as well.

I have a hybrid bike with the exact same 7 speed freewheel and chainring, last week the freewheel went bad so I got this one the bike had the same tires as your's and I went with 700 x 30 tires and the bike is a bit faster but not as good as a road bike. Why not buy a used road bike as it's going to be far lighter than the wife's bike.

u/Da_Funk · 1 pointr/bikewrench

Haha, yeah I took the advice on replacing the freewheel seriously just in case.

Thanks for the knowledge. I haven't considered this replacement up to now. I might give it a shot to keep the bike crisp and functional as well as getting my mechanic skills up with the experience.

Here is a follow up question, would a 7 speed like this fit or would the extra gear take up too much space?
