Where is all this love for coaster brakes coming from?! They are, IMHO, one of the worst brakes ever. They have caused me numerous spills and scraped knees (due to the rear wheel locking up and skidding out from under me) and have done the same to my kids. There is virtually no control over them, and they don't allow you to shift your weight around when standing on the pedals to go around sharp corners or off-road. (Nevermind trying to shift your weight backwards when stopping quickly)

I have hydraulic disc brakes on my bike, and they are the greatest thing ever! Yeah, they require maintenance, but totally worth it.

In my experience hydraulic disc brakes require less maintenance than rim brakes.

Living on a hill (like I had to go up a ~150m 23% wall to get home, and go braking down it to go places) meant I had to spend frequently on rim brake shoes and, eventually, rims. The frequent rain and mud makes it to the rim brake shoes and diminish braking power if you don't keep them clean.

That doesn't happen with hydraulics - clean them with alcohol, bleed them once each year and you're set. I agree, they're the greatest thing ever.

Childhood nostalgia? They are indeed terrible brakes from a riding perspective. But a) no cables or pads to mess up, b) beginner friendly and c) skidding. Great for kids riding around the neighborhood, the only real purpose.

Skill issue ;-) My first bike I learned to ride on was a BMX with coaster brakes that was part of the fun! Rip down the street then slam the pedal back to leave skid marks. And who didn't love slowing down a bit, then slamming the coaster brake while turning the handle bars to do a sick rear sideways skid. My next bike was also a BMX with a rotor and front/rear pegs. That lead to way more spills trying to do stunts on the pegs or spin the handle bars. Never got good at the stunts part.

Might have worked better for a smaller, lighter me but I would like to give coaster brakes a go again on a proper sized BMX.

They were not impossible to control. It wasn't easy, but you quick got used to it and got enough. Partially that was learning to plan a head so you didn't need to much control. Or you learn to enjoy drifting the back wheels.

I agree with you, coaster brakes suck. And losing your brakes if the chains drops is really serious, especially because it tends to happen when you need brakes the most.

Cable disc brakes have come a very long way and there are some decent models that require very little maintenance and work great.

Also for every skid you get on a coaster brake I'll raise you a nose Endo with the front disc brake!

TBH I don't care for hydraulic disc brakes much.

My -favorite- setup for Discs, at least use to be, Avid BB7s with Avid Speed Dial levers, with Flak Jacket Housings.

That combination was super simple to 'dial in' (Hydraulic brakes tend to be a lot more inconsistent on 'feel' unless you are very persistent about bleeding and know how to use a disc tuning fork) and honestly had a lot less overall drag than I've experienced with most hydraulic discs. Replacing cables is way easier than re-doing hydraulic lines, also you don't have to worry as much about overheating janking up your fluid. Only drawback is, yes, make sure your cables are set up right and clamped down good.

But yes, Coaster brakes suck, especially since 'failure' means either rebuilding the wheel or outright replacing, because nope, not gonna do that sort of hub job.

They're legally required in a lot of countries on small kids bikes and not easy to disable. I think the argument is that kids lack the strength to operate a hand brake effectively. Experts all seem to say that coaster brakes are terrible for safety and learning though.

We used to call coaster brakes "torpedo" when I was a kid and, yup, they're totally horrible.

If you've got coaster brakes I don't even know if you can learn to trackstand (you need to both slightly pedal forward and brake, and adjust by slightly pedaling backward): trackstand looks like you're idle but micro-adjustments are constantly happening.

Then I take it probably could wheelie a bicycle with coaster brakes but I fear it'd be hard: same things, you do micro-adjustements and they're not only done with the rear brake. I'm pretty sure I do pedal backward a bit when I do wheelies.

And when I readjust the position of my feet on a bicycle: I do it while backpedalling.

Last time I used a bike with coaster brakes I realized how dependent I became on being able to pedal backwards.

Incorrect. They're perfect for everyday utility cycling. You just need to learn to use them properly.
