I'd recommend a Cyclocross bike (also called CX). That's a robust road bike frame, configured to accept tyres up to about 40mm wide. You won't need 40mm unless you're doing proper off-roading, but a nice 30-35mm file tread such as a Specialized Trigger or Schwalbe Sammy Slick will run nicely on smooth pavement, will handle cobbles and bad pavement, and ...

We don't do product recommendations here. Generally speaking, a road bike will be faster than a MTB for the same rider. That said, road bikes are less robust. I've popped road tyres on potholes that a rigid MTB would barely notice. Tyre width won't change the frontal area of the bike by much if anything. Instead, the wider tyre allows use of a lower ...

Those appear to be hooked rims,(difficult to see in the pic) which are almost all iso-622. iso-630 rims are usually straight sided rims and used only on 25-50 year old road bikes. Occasionally tires are just made with tighter bead wires. You must fully deflate the tire and break the bead seal all the way around on both sides so that the edges farthest from ...

Try using a different pump. I had the same problem and couldn't find a leak, replaced the tube and still had the same problem. Eventually I tried a different pump and no problems. The pump I had must have been damaging the valve.

Check the rim strip and make sure it is covering all the spoke ends. Buy a kevlar belted tire that will handle more than 60 PSI or buy thorn resistant tubes. They are heavier and more expensive but last about 10 times longer between flats. By your description, you have a hybrid. 60 PSI is too low on a medium width tire for a 242 lb. weight. I weigh 190 and ...

So after tinkering with derailleur position some more, I still couldn't get it to stop rubbing, that's when I had the bright idea to move the clamp bolt to the other side of the derailleur. Now I've got enough clearance that it doesn't rub against the tire and the chain doesn't rub against the cage. There's not a groove for the wire on the other side, but it ...

The roadie will probably be faster. The mountain bike will not even be a mountain bike. At your price range: Tyre rolling resistance, both bikes will probably have crappy tyres, it is likely, but not certain, that the road bike will have less rolling resistance. Weight of the bike, the MTB will be at least 3 kilos heavier, this is a plus on descents, ...

The solution to fix this was in the Pinkbike article suggested by @Batman in the comments to the question. If you buy a radial tyre patch designed for a car then chances are it'll be plenty big enough to patch a hole in a bike tyre. I just went for some cheap ones on eBay. Add the vulcanising glue (plenty of it) to the inside of the tyre and stick the patch ...

Try taking the tire off the rim, an use Krazy glue to shut-close the cut. Then boot the tire from the inside. If you have an old useless inner tube, cut a nice piece and use it to glue it inside the tire. I have put about well over 2000 miles after I did three of these repairs from 1" screw-incurred flats on my rear tire in my commuter bike.
