Welcome

I am 45 and based in London. I have got a red Belisimmo single speed bike I bought from Evans on special offer for 300 pounds reduced from 400. Frankly I have had nothing but trouble with it. It had mudguards but they were so close to the tyres I had to remove them. Metal swarf from the wheel rims kept coming off so I had to fit softer break pads. The back wheel keeps coming loose because the bearings in it are worn already after just a few months.

I'd have taken it back. Never even heard of Viva.

Edit: I'd have taken it back because of the worn bearings, not because it's a Viva. Evans/Cycle Surgery generally have a warranty period as do the Manufacturer of the bike.
