I Got my missus the 07 model WS Carrera Vulcan with cable discs in a halfrauds sale for ~£230 (if I remember correctly), the one linked above above doesn’t look to have changed spec significantly since then…
She’s been coaxed round Swinley on it and hated every second, the bike was more than up to it, unfortunately She wasn’t… Otherwise it’s fulfils it’s weekend tow path and pub duties extremely well…
For a “leisure cyclist” it’s great; plenty of gears, comfy riding position, brakes work well enough… not super light but reasonable in terms of weight and it was quite cheap the weekend boy tried to flog us some Apollo POS for £50 less but I was having none of it…
The frame is an excellent base for upgrading should she ever get more serious (which she won’t) and want fancier parts, They’ll all fit with minimal fuss, the standard parts (IIRC) are; SRAM X4/X5 mechs/shifters, Truvative Square taper cranks, MX2 – 6” cable discs, cheapy 3.5” Suntour fork, and un branded finishing kit… does the job.
