Within 12 weeks he took to the road with a boot full of spare parts and two sports bags holding his clothes in the passenger seat.
He completed the drive despite being caught up in an earthquake in Panama and a Taliban attack in Quetta, Pakistan.
Mr Locock said: 'I woke up one morning and the hotel was shaking. 'There was mortar fire outside, followed by small arms fire. 'The Taliban were firing on the army garrison next door.'
Despite those close encounters, the retired radio engineer said the only time he feared for his safety was during the worst floods in 30 years in the Northern Territories, Australia.
His trip took him through Western Europe to Iran, Pakistan and India before taking the boat Down Under via Thailand. After a tour of Australia Mr Locock took another boat to Argentina from where he rode along the pan-American highway all the way to Canada before heading home.
