Interesting brake set-up.

Yeah, I've noticed that on trikes before and meant to find out wtf is going on. My suspicion (I haven't checked it) is that there's a stipulation that all competition bikes must have two brakes without stating that those brakes have to be on different wheels so it's a way around the difficulty of putting rim brakes on the rear wheels - which would probably make the trike pull dangerously.

Anyone actually know?

C3PO

From the British Tricycle Association's website:

The Road Traffic Act requires all cycles to have at least two independent brakes on the machine.
On a bicycle there should be one on the front wheel and one on the rear wheel, however tricycles are allowed a deviation to this rule, allowing two brakes on one wheel. For tricycles with two rear wheels this must be the front wheel, for those with two front wheels on the rear wheel.
The inherent problem for bicycles of tipping over the handlebars when the front brake is applied suddenly is less of a problem on a tricycle, as the weight of the axle tends to counterbalance the rider. The worst normally experienced is a jolt as the rear returns to earth. Due to the extra wheel, there is little danger of a front wheel skid causing a fall.

I can't believe I'm getting involved in a thread about brakes on tricycles .......

We need a tricycle sub-forum.

Makes sense.

That would be my guess too. There's too much scope for imbalance on the rear brakes unless you're using hydraulic discs or hub brakes.
Cars can fail an NCT for imbalance, so it's obviously relatively dangerous.

The little folding bike on slide 7 apparently requires an HOUR of your spare time to fold down! Still, this slight impracticality is more than compensated for by its sublime aesthetics.
