A disabled mountaineer is free to roam the countryside again - thanks to his chopper-style mobility scooter.

Bill Robertson, 66, was a keen rambler until he was struck down with cancer and circulation problems.

He has climbed Scotland's second highest peak, Ben Macdui, a staggering 21 times before his mobility and energy significantly reduced in recent years.

Bill is now only able to walk a few steps at a time and was largely housebound until he got a hold of a mobility scooter -- which looks like a Harley Davidson motorbike.

The three wheel black and chrome TGA Supersport is capable of taking on the great outdoors and allows Bill the freedom to explore countryside tracks and trails.

Glasgow Times:

Bill said: "I owned a scooter before my current Supersport, however, there was no way it could tackle muddy fields, slopes or rocky paths.

"Whatever the slope or terrain, you feel like the 'centre of gravity', totally stable and safe.

"After being stuck in my house for so long, the opportunity to get out to see the wildlife including kestrels and eagles in Hazelhead forest has been priceless."

Retired Bill, from Aberdeen, had a varied career which included working in the motor trade and serving in the Merchant Navy.

Before his triple heart bypass, ventricular hernia and cancer, Bill had been an eager hill-walker and mountaineer for over 35 years, especially in the Cairngorms.

He added: "I have adventured in the Cairngorms for many years alone or with my son and grandson in more recent times.

Glasgow Times:

"However following a triple heart bypass and now suffering with the affects of severe DVT, a ventricular hernia and Cancer, my life can be difficult sometimes.

"My new Supersport is a real life-line and has allowed me to once more venture out into the local nature reserves and enjoy peace and quiet.

"I spent so many years doing stressful, dangerous and noisy jobs that being able to spend time alone and surrounded by nature is a tonic that can't be matched.

"These days I may not be able to lead outward bound parties of children or instruct on abseiling, but my scooter has allowed me to continue adventuring and discovering natural Scotland at its best."

He has only owned the scooter for a few weeks but has already clocked up over 20 miles.

The scooter is a favourite of the Disabled Ramblers Association and has previously featured on the BBC's Countryfile programme.
