Two Bikes, two very different problems.

I'll do my best to describe the issue here, but i may need to get some pics tomorrow to really make myself clear. I have an old schwinn, the only thing i know about it is it's from the early 70's and my wife has a Step through frame trek, i know even less about, it was a yard sale find.

my schwinn will not shift properly the front works perfect, the back one will not go into fifth gear, the chain also tends to jump off the gears when I'm standing to pedal up steep hills... that's a dangerous condition i found about the hard way, luckily i didn't get hurt badly just some scraps.

My wife's Trek on the other hand is a little harder to explain? i have no idea what the problem is it manifests as the crank not catching when pedaling after coasting. Like i'll coast around a corner where all my effort is going into making the corner without slowing down too much and than i'll go to pedal out of the corner and its like there's no chain on the bike at all, after pedal for like 30-45 seconds it catches again and it works fine till i coast again. Needles to say very annoying, i was riding down Lombard and the chain came off so i put it back on and after that it was like this.

Any advice before i take them into a shop would be great i don't want some bike shop person to see a helpless girl who knows nothing about bikes and try to sell me parts i dont need. i'll probably be taking the trek in next week since its more comfortable for me to ride and my wife doesn't ride it anymore.

Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter

Your wife's bike is easier to diagnose. Odds are the freewheel (or freehub) ratchet mechanism is full of dried lube, and the pawls are sticking in the open position after coasting and not engaging immediately.



These usually respond well to flushing with solvent and re-oiling (oil, not grease). You can search "flushing a freewheel" or a similar phrase for instructions how to.

Your bike sounds like it needs basic derailleur adjustments, but the description is too vague for me to give specific help.

In any case, Portland has 3 bicycle co-ops where you can get low cost repairs, and/or do it yourself with advice from a pro. If you're not bike knowledgeable one of these may be the first place to start.

thanks, i'll try flushing and re oiling the free wheel on my wife's trek before i take it in, might save me quite a bit of money.

my wife's bike, okay this is actually kinda funny, and the fact that it all started on a particular ride with no warning makes sense now. i pulled a shoe lace out of the rear gears it was all mangled in their... wow. i took the rear wheel off to flush and oil it and i got to looking at the thing and there was a shoe lace in it.... i don't wear lacing shoes when i ride i have a pair of stiff soled walking shoes that i wear when i ride so its not mine.



Thats what i pulled out of the gears in was lodged between three of them and the hub. anyway, it works a lot better now, i still need to flush and re-oil it but at least i know what the initial problem was.
