A man from Germany is claiming a new Guinness World Record for the world’s heaviest rideable bicycle.

Frank Dose, aged 49 and from Schleswig-Holstein, rode his self-built bike 100 metres at the weekend, and is now waiting for Guinness World Records to certify his effort.

The existing benchmark stood at 860 kilograms, but Dose’s machine – with tyres recycled from an agricultural muck-spreader – weighed in at a whopping 1.08 tonnes.

He hit a top speed of 5 kilometres an hour during his record-breaking attempt, which won’t win him any Strava KOMs, but still … chapeau!
