Whilst it is good that cyclists have been considered here, the design is abysmal. To remain within the law, cyclists have to dismount in the carriageway, push their bikes along a few metres of footway, and then remount their bikes to continue. Additionally, because every effort has been made to speed car drivers through the roundabout, both pedestrians and cyclists have to wait for a steady stream of motorists, but courtesy of the bend in the road the sight-line when heading South-West is abysmal. Meanwhile traffic can come from the right from no less than three roads using the two available lanes. It doesn't have to be this way, and shouldn't be.
Cyclists and pedestrians should have priority, and a severe speed table built to force motorists to drive dead slow. The roundabout needs to be narrowed to one lane with a cobbled overrun area. None of this is new engineering design, and the techniques are perfectly legal in the UK. It could have been designed this way from scratch, which would have been much cheaper.
