What's this on my new wheel and why?

[malcolmlauder]

Forgive my ignorance, but what's this cog on my new front wheel and why?

It's in case you want to run disc brakes. You bolt the rotor onto it.

[malcolmlauder]

Aah, cheers[emoji106]

[cycleruk]

Are you going to run a disc brake?
If not, are the rims meant for normal brakes?

Or you can bolt a cog to it, fixed gear.

Looks like you've been sold the wrong thing

[malcolmlauder]

It was advertised as suitable for V brakes and disc brakes. I'll use it for now and see how I get on. I may convert to disc brakes if I feel like it would be beneficial...but that's a whole other thread![emoji4]

But it's a front wheel! Why would you bolt a fixed gear cog to a front wheel?

Turns it into a back wheel, or it stays on the front and you have AWD aka chelsea tractor

I thought that you needed different forks for disc brakes (or rather strengthened forks to handle the different loads from disk brakes) - as well as attachment points, etc.

Disc brake suitable forks can be purchased for as little as £20.

cycleruk has a very relevant point here - if it was me, I'd go back to the bike shop and fully check it out with them.

Now, please pardon my ignorance as well, but is the spokeing correct for a rear wheel, and particularly a fixed rear wheel - and pardon further ignorance, but would a rear wheel fit into front forks? - I know that bikes and their components vary widely and wildly, but on my road bikes (the only type of bike I've ever had), a fixed or otherwise rear wheel would not fit into front forks.

I have to wonder what kind of bike shop would sell a wheel without asking the kind of brakes you use. Do check on the rims.

[malcolmlauder]

It was an internet purchase. Entirely my mistake. It fits my front forks fine and my V brakes work fine with it. I have no intention of using it as a fixed gear rear wheel so i'm happy with it. I'd love to have the type of relationship with my local bike shop

[malcolmlauder]

...that would allow me to avoid this type of thing and avoid fleabay, but I'm sad to say I find them rude, snobby and arrogant, so I will just have to learn from my mistakes. Happily the wheel is fine[emoji106]

[mercalia]

since every one has given the sensible answer I add is how you attach an electric motor to turn the bike into a pedelec
