    fat rear hub

    I currently have a bolt-on 36h, 190mm, threaded freewheel rear hub. I want to change over to a cassette hub with the same 36h, 190mm specs(bolt-on or QR). I cant seem to find a hub with all those specs. a little help.....

    Really. All of the good hubs are 32 hole.
    How much do you want to spend? I have bikes with Bike Hub Store hubs and Hope hubs. The BHS hub is 140 bucks. Hope Pro4 is like 240.

    The big issue here is the 190mm hub width and 36h requirment, which makes me think this is from a wallyworld fatbike. Mongoose dolomite, hitch, or malus.

    Replacments are available, and I know there are or were 190mm 36H freehubs available on aliexpress. If you search the "mongoose dolomite" thread, you'll find some links on there. ultimately, this is one of the reasons I sold my dolomite. Finding a replacement rear hub was not an easy task, and ultimately it was cheaper to buy a better bike with 170mm spacing and sell the dolomite.

    lookin around 32h hubs seem to be the beez neez. im installing a front motor hub with 36h. 36h is what my current rims have and want to keep. 32h hubs are whats out there in 190mm and actually prefer to get but I don't want mismatched rims. if I can find a 32h front motor hub , im going hope hub in the rear laced with clown shoes.

    Maybe not directly, but it's relevant because 36h hubs are extremely uncommon.

    32h is the most common because it's plenty strong laced 3x with halfway decent rims.

    No, but the listed specs indicate that it's an otherwise cheap bike. 36h hubs are there to cover up the fact that the rims are cheap and probably not very strong. It's also an e-bike, which is a relevant fact that you conveniently omitted from your original post. It makes sense that a motor hub will have a higher spoke count. But that doesn't mean it's necessary for the non-motorized hub to also have a higher spoke count.

    What bike is it? Wally world bike or not, a 190mm hub with 36h is rare. Aliexpress is the only place I heard of them, unless you buy from Pacific Bikes (mongoose's parent company, which is the manufacturer of wallyworld fat bikes). But they only carry the freewheel hub, which you've already had issues with.

    @ watts888: rare yes, cheap maybe. no issues, just don't want mismatched rims.
    @ Harold: all I was asking for was some info on hubs, not how cheap my bike is. sorry I cant afford a $2-3k bike, dick

    Still doesn't answer the question about what bike it is.

    Cheap bikes can still be good bikes. I owned a Mongoose Dolomite, one of those bottom of the barrel wallyworld fat bikes. It was fun as hell, and worked pretty good, except the rear hub. The axle bent after the first couple days. Everything else was good if you knew how to regrease the bearings and adjust them. Lately, I've been riding a trek 820, one of the cheapest bikes Trek puts it's name on. Hell of a lot of fun on the trails.

    its not an ebike, I'm installing (planning on) a front motor hub. it has a 120mm BB, 190mm rear spacing, some cheap suspension fork 135mm, aluminum frame.

    That's the killer. If it was a steel frame, you can bend it in and use a 170mm rear hub, and there are lots of 36h hubs available in that size. I think aliexpress is going to be the only option. As an alternative, you can use 190x12mm thru-axle hub if you can find one in 36h, but you'll have to file about 2mm off the rear dropout to get it to fit. Not hard, but another option.

    for the e-bike conversion, have you looked at doing a mid-drive motor instead. I've heard a lot of people say that putting a front hub motor on a fat bike can cause some crazy steering issues. You can get a 120mm bottom bracket cut down to work with a 100mm mid-drive motor too. Pretty easy since it's aluminum.

    I own one, and yes. 100mm rims will fit. It's more about the tire width. 4" is no problem. 4.5" and larger start getting into issues. Of course, every tire manufacturer lies about their tire width once you get up into this range. I have a surly 3.7 that's as wide as my 4.0 vee missions, and when looking at some bike specs on the diamondback mason, their 3.8" tire actually comes out about 2.8" when measured.

    hey swerny, how was I needlessly rude? I was asking a question about hubs and the guy tells me I have a cheap bike. How's that not needlessly rude? Did I ding him? No. But I guess this forum, much like others, has guys with a massive sense of entitlement.
