Specialized Hard Rock in neutral

[BillyBru]

My Bicycle isnt working for shit. I know nothin about fixing bikes. Everything turns with the pedals and chains but then the tires and wheels dont turn one bit and its like the bike is in neutral. I was wondering if anybody knows about bikes or what could be the problem.

Thanks,

Is it making any weird noise? This is a mountain bike right? Do you know is it a freewheel or a cassette hub? Either way the pawls in the cassette or freewheel could be stuck and not engaging.

yeah its a mountain bike and it hasnt been making any weird noise. from reading online and looking at the bike i think its a freewheel. and what could I do to fix it?

You can replace the freewheel or cassette body. Being 7 sped it could go either way. Can you take a picture of the rear cassette but more of and angle so I can see the side?


In reality I'd say this is too much work for someone with out the specialty tools and k ow how. Freewheels are easy as the tool is usually about $5-$10 depending on which one you need the. You just drive the bus left.


Take the wheel off and bring it into a competent bike shop. They should be able to find you a replacement for not too much.

Judging by what you said, the two or more teeth between the hub and the gear cassette are seized or are not engaging. (likely that the spring that engages the teeth has broken) Taking the cassette off yourself is inadvisable unless you are prepared for having to deal with dozens of small ball bearings.

If you are dedicated to keeping these wheels with the bike, take it to a bike shop for repair as stated above, otherwise you can buy a better set of wheels or have some built specifically for what you use the bike for.

yeah im planning on keep everything that still works. I forgot to say that sometimes the bike engages and sometimes it doesnt. and when it broke while i was riding it i would have to get the bike up to a good speed and it would engage then if i stopped peddling it would be free again. im planning on taking it to a bike shop but just wanted to see what was up with it. i feel like one of those parts is worn out.

 

[RebelGTP]

yep, there is a ring that holds the ratcheting teeth up to where they will engage with the teeth in the gear cassette. this part has either broken, become dislodged, or worn out. The ring acts as a spring to keep those teeth under tension.

Broken freewheel. I'd say less than $30 to replace it. I'd just take the wheel off and bring it Into a bike shop. I'd bet they'll swap it for you no problem. It's like a 3 minute job.
