Concept Bikes & Bike Innovation - for better or worse

Hit a pothole, it'll slap you on the arse, and you end up punching the person behind you.

Ha!

it'll slap you on the arse

Some people pay good money for that kind of service.

I ain't mad at it

I don't find it convincing at all:

geared steering

Seems unnecessary, some swept back bars would be simpler and having your hands behind the steering axis is just different from having them in front of it, not better or worse.

If you use a chain to connect the steerer axis to the handlebar pivot axis, you have to have the drive ratio at 1:1 and the axis distance an integer multiple of the chain pitch, otherwise the phenomenon of chordal action will cause 'cogging' in the steering response. You'll probably end up thrupenny-bitting every turn at best, and throwing the damn thing in a ditch at worst.

You can have a non-unity ratio between handlebar and fork rotation with a simple pushrod as used on Bullitts and other similar cargo bikes without the backlash and cogging inherent in a chain drive.

Gotta do it naked!

But does it heat the water as well as spin the drum?

wash your clothes and exercise at the same time

What, just like people always used to when they hand-washed? If the idea is to reduce impact on the environment, building a big plastic single single-purpose machine seems like a worse idea than just using the sink you probably already have.

Legs vs. Arms though.

Sinks >>>

I want one.

sinks ? what century are we in ?

Legs vs. Arms though

Stand in the sink and do the hard work pedally rather than manually if you don't want washerwoman's arms

The Washer Womans Arms. Good pub name.
Washer womans arms = @ChainBreaker

you calling my arms washer women!?!?

Ah, but if you actually comparing manufacturing big (plastic) single single-purpose machine then compare it to other big single single-purpose machines like

Reduced wastage and exercise.

we that was unexpected... I thought he'd nail it. Also thought he was about to pull the handle bars off at one point...

Nope.
I have one, no issues with it retracting when it's not supposed to. Not saying it's beautiful, but it works perfectly fine.
