Braking by back-pedaling

[Dirk]

I had a bike with a 'Perry Coaster' brake about 55 years ago. Certainly taught me a lot about rear wheel skidding.

These have a coaster rear brake, NSU Quickly.

Yeah, although that approach doesn't really work on a Christiania trike, especially when there's a child on the bike on the back (followme tandem adaptor)

I bloody loves coaster brakes. At one point 80% of my bikes had coasters, now only 75% of them are so equipped. Got a fresh 2 speed auto on my Electra......

If N remains unchanged, that means you have 20 bikes, and changed one from coaster brakes to cable pull brakes and now have 15 with coaster brakes. If N didn't remain the same, the change from 80% to 75% can't have been the result of gaining or losing only 1 bike. N-2 throws up the possibility of you having had 10 bikes (8 with coaster brakes), but then getting rid of 2 of the coaster braked bikes leaving you with 8 bikes, 6 of which have coaster brakes. N+2 suggests you had 10 bikes (8 with coaster brakes), and you added 1 with coasters, and one without leaving you 9 coaster-braked bikes out of 12. Any which way, you have too many bikes!

Yes, I'm bored.

I totally followed your reasoning until the underlined part where you lost me.

My bike as a kid only had a coaster brake. I didn't get a bike with hand brakes until I was 10 or so. Never had any issues

Coasting brakes. Nightmare.

My dad's first motorbike was one of those, he went all over the county on it .

He was only popping down to the shops but he could not stop.

The "Boris" bikes in the European cities I've visited have all had them. Do the ones in London?

The original bikes had hub brakes front and rear with levers on the bars, there are some newer ones now but I think the brake setup is similar.

Pretty common on American kids bikes and cruiser bikes, but I dislike them. Much prefer braking in the usual fashion.

It is not possible to have too many bikes.

Yeah it is.

About 10 years ago, my daughter and I hired "Dutch" bikes with back pedal brakes for the day whilst on holiday in Belgium. She coped alright with her's, but I was a right mess on mine... but we did get the bikes back in one piece, thankfully.

Your fatal error was to assume that N remains unchanged.
I had five bikes, one of which was non coaster. 4/5 = 80%
I gave one away which left me with four bikes, one of which was non coaster. 3/4 = 75%

I have several coaster hubs lolling around in the garage including a 1940s vintage Simplex twin-stripe two-speed kick-back hub awaiting the right bike/frame.
