Disc brake --- the rear brake is a back-pedal job, unfortunately, which makes it a write-off from my perspective; years of cycling ordinary bicycles mean that I tend to automatically move the pedals backwards while coasting to a comfortable position, and doing this with a back-pedal brake leads to unhappy experiences.

I'm impressed by the add-on bicycle trailer, obvious being sold as a first-class citizen. A lot of IKEA stuff is modular and eminently hackable --- like, literally today I have assembled 40kg of random furniture into a workbench/desk for my study by bolting together bits of office with bits of bedroom. I'm sure there's interesting things to do with it. It looks like you can restow the towbar to make a convenient handle for pulling it.

Oh, yeah, it's an automatic gearbox, too.

Here's a random review:

Coaster brakes are somewhat common on city cruisers, but it is a little odd that they've chosen to go with the combination of the two.

I reset my pedals when I'm coasting as well, and it's probably fair to say that we're not the target market. My guess is that it'll be popular among (shorter-distance) city commuters and college students who would've bought a Huffy or something equally shoddy instead.

I've seen the combination of a coaster brake and a front brake on some kids' bikes. I believe the thinking is that a coaster brake is friendly to novices, those with weak hands, and those who knock their front brake out of adjustment and don't know how to fix it. While a front brake gives riders who can actually get above 12 mph some actual stopping power for safety.

Reliance on a single coaster brake is dangerous. When a coaster brake fails, it can fail in two ways that are both very dangerous: full lock-up or full brake failure. They also have the tendency to catch at strange points in the pedal movement, like the vertical noon/6 position, which are difficult to establish the needed force to slow the bike.

I have a Shimano Nexus 3 speed with a coaster (and hand brakes) that is my daily driver, and where the coaster brake catches is pretty random. I can sometimes make several, as in 3 - 5, full backwards pedal rotations before it catches, other times it catches immediately. I am now in the habit of catching the brake before I descend any large hill. Since I live in Nobb Hill SF, that's every day.

You should get your coaster brake fixed, since it is apparently dangerous for you.

I have never had a coaster brake failure. Nor have I experienced a problem with engaging the coaster brake as you describe. I have always found the single coaster brake to be more than adequate and to be more reliable than any (set of) handbrake(s). I like the fact that I can skid the rear tire if I apply enough force. I live in a non-hilly area, so YMMV.

I think coaster is fine as backup, but front brake should always be the primary brake as the braking distance using it is much much shorter.

Haven't had a coaster brake since the Schwinn Typhoon I had as a kid in the 1970s but the coaster brake was flawless. I think it was Bendix. Never failed to engage and was very controllable.

Of course Schwinn today is not the same as they were then.

Went bankrupt in 1992, Pacific Bicycle bought the brand. So still a bike in name only

Two brakes are required by law in at least four EU countries I'm familiar with, very probably all of them.

What's unusual is having a disc brake as the second brake, but I like those much more than rim brakes.

Some countries such as Germany mandate that you have two independent braking systems on a bicycle, so the coaster brake is probably here as a cheap backup.

Of course everything depends on your riding conditions. It's hard to get sufficient stopping power from the rear brake when going downhill, especially if it's wet out. I had a situation once, where I slid into traffic, because I applied the coaster brake on a very steep grade. That day, I installed a front brake.

"we did have a few niggles about how it had been assembled which much to our amusement on our first test ride the handlebars went one way while the bike carried on going straight"

This is enough reason not to buy a bike from a non-bike store, unless you have the skill to reassemble it yourself.

Why can't you just rotate the pedals forward to a comfortable coasting position?

You can only do that while moving; once you've stopped (e.g. at traffic lights) the pedals are stuck where you left them, unless you lift the rear wheel off the ground.

When I moved to Copenhagen from London, it took me several weeks to get used to a coaster brake rather than disc brakes -- I'd often stop with the pedals in the wrong place.
