If you’d rather choose horse power over pedal power then ignore the advice below and opt for this: the Harley-Davidson Blue Edition.

A collaboration between Swiss watch and jewellery maker Bucherer, and bespoke customiser Bündnerbike, this is the most expensive motorbike ever made.

The result of eight craftsman working for 2,500 hours, every metal element has been forged by hand.

The customised one-of-a-kind Softail Slim is studded with nearly 360 diamonds and garnished with plenty of gold plating – including the hand levers, reservoir caps, and foot controls.

The throttle valves – also gold plated, natch – are illuminated via heat-resistant LED lighting. Its iridescent blue finish is created by layering six coats of different blues atop one another.

The bike houses a 1,888cc V-twin engine which delivers 100hp power. But more impressive are the two ‘safes’ on either side of the fuel tank. The right one contains a unique Carl F Bucherer watch based on the Patravi TravelTec II, while the left contains a Solitaire Heaven ring with a flawless 5.40 carat diamond from Bucherer Fine Jewellery.

So, probably not one to leave overnight in the Lidl car park, then.
