CDHPOWER26" Bicycle Rear Mag Wheel 135mm for Rotary Freewheel,Aluminum Alloy Black Rear Bike Rim

the wheel is perfect, worth every penny. I like the high quality aluminum, very clean. I run these on motorized bikes, my first being a Predator 212, and this wheel is going on a Monster 90 powered bike. My 212 bike tore up spoked wheels, so I switched to this 6 spoke wheel 7 years ago, and it still looks, and works like new.

This wheel answered my prayers. Nowhere, and I mean NOWHERE could I find a mag wheel that was disc-ready with a rim breaking surface. It's very well built too. The hub and bearings are solid. I've bought many mag wheels that had a hollow hub. You'd look inside and only see the bearings supporting the compression of the tightened axle. Not this one. It's got a solid tube running end to end that houses the axle. I do recommend putting some Red and Tacky grease in the bearings...but it's not necessary. Even the nuts that come with it are solid. Everything threaded is threaded well.For those just getting into making a motorized bike, just do yourself a favor and get rid of your spoked rear rim. You'll be screaming at your bike trying to get the bolt on sprocket adapter even. Plus the stress on the spokes will snap them over time. Also, using disc brakes with a chain sprocket right next to it limits the sizes. You'll have to get a very small sprocket, minimum 36 tooth, and a very large disc rotor, at least 180mm. Using rim brakes is far far far easier. Plus in my opinion, they stop better.I know this wheel is a little expensive, but it's well worth it. It'll save you so much hassle.

The first one they sent me had damage threads. And then I sent it back tried to send it back and I had nothing but trouble not their fault. They sent me another one which work great up until the chain fell off and it's stripped out the bolts holding the sprocket for the 80cc motor. The chain stretched not their fault again so far I've had nothing but good luck with this rim since these two problems. I forgot one thing I had to use a Dremel on the valve stem hole because the valve stem wouldn't fit all the way through. It wouldn't allow me to use a regular hand pump I had to go across the street and you the gas station air There's a picture.

Be aware this is for rear wheel ONLY. You CANNOT buy matching front wheel separately, only in a set. Wish I would have known before ordering

good study wheels.

The description says that the wheel was specifically designed for motorized bicycles . The only thing I can tell makes that true is the fact that they are round . I had under 20 miles on them when on thesecond day of riding I had all 6 bolts that were securing my rotor and sprocket to the rim snap off clean . Causing the rotor to bind up and bend, braking the hydraulic caliper. Also sending me over the bars in traffic at 30+ mph. I highly suggest a better quality wheel with a min. of 36 12g spokes inside a double wall steel wheel . Even with a stock chinadoll motor. I will never run a magnesium wheel again on a motorized bicycle again . Especially these wheels . Complete garbage and waste of money . Do not use these wheels on a motorized bicycle if you value your life .

I do deliveries for a living, it's been 6 or 7 months, hundreds of hard starts, thousands of even harder miles. Not even a scratch. Amazing.Edit, as of October there is a slight wobble in the bearings, hasn't gotten worse,and I can't feel it while riding, but it's there.I have only cleaned and greased it twice, so I don't know if it's my fault or not for not enough maintenance.

My 2nd rim for both bikes. These Aluminium rims are a whole lot stronger and better. They give you 2 - half inch wide washers for easier way to balance whole rear tire on the bikes and to ensure to measure smooth rolling that does not pressure any of the bearings on both side of the Rims. If it doesn't state Aluminium DON'T buy it. Love the smooth rides.
