Need opinion and advice (Newgen Bike)

[Littleze]

Hi. Got a puncture in the rear tyre of my 345-s. I’m a novice cyclist although, I have removed wheels and replaced inner tubes on a standard bike before. I’ve bought a replacement tube and a set of reinforced tyre levers but after taking one look at the rear wheel set-up it looks very complicated. I’ve looked for any guidance on NewGens website and YouTube but had no joy. Any advice would be very welcome

I’ve taken mine to a motorbike garage, less stress.. as was facing the same issue as you.
