Rymel, (pictured right), who suffered a broken neck and damage to his spinal cord when he was involved in a crash at Edinburgh on September 2, has been laid up in hospital ever since.
After being transferred to the Spinal Injuries Unit at the Southern General Hospital in Glasgow, he underwent an operation on his neck when bone was grafted from his hip.
There were initial fears when he discovered he had no feeling or movement in his right leg.
But as the Bandit continued his rehabilitation, the feeling and movement returned, and last Tuesday he was able to walk for the first time.
A statement issued by the club said the Czech had amazed medical staff by getting to his feet and walking 70 yards around the unit's gymnasium with the aid of a stick.
"It really is wonderful news," said a spokesman. "Obviously, he has a long, long way to go to regain full mobility. We have to remember Adrian has a broken neck, a splintered shoulder-blade and a broken wrist in addition to his severely-damaged spinal cord – but to see him standing up, and taking these first steps, is just marvellous!
"It is less than three weeks since his accident, and in the beginning his doctors would not even commit themselves as to whether he would be able to move all his limbs again, let alone get out of his bed and walk – now the authorities are telling him to slow down, and not take too much out of himself in his sessions in the gym!"
On Saturday, Rymel was allowed to leave the hospital with friends for a car journey and barbecue in the nearby Robertson Park.
A hospital spokesman said: "Adrian wanted to light up a barbecue in the hospital's courtyard, but of course we couldn't let him do that in the hospital grounds.
"But he has done so marvellously well, and is now walking with his stick, we saw no reason not to give him an afternoon of freedom in the sun – so off he went to the park to sizzle his sausages!"
Rymel's recovery news will act as a perfect fillup for the rest of his patched up Berwick team who this Saturday (October 2) are due to take on Newport at home in the quarter-finals of the end of season Young Shield.
"We always have trouble with the Wasps" admitted club boss John Anderson.
"In recent league visits, they forced a draw last season and went down by only three points in July this year – to move on into the semi-finals, we'll have to do a much-better job this time around"
Berwick are of course without the injured trio of Rymel, fellow Czech Michal Makovsky and Poland's Michal Rajkowski.
Last week Anderson admitted the club had been on the look-out for an emergency signing, but as they had been unable to draft anyone in before the signing deadline, they would have to cover with the riders currently available to them. The second leg of the tie will be in Wales, on Friday October 8.
Berwick's Lee Complin represented the club in the PLRC at Sheffield on Sunday where he scored seven points. Meeting winner was Newcastle's Kenni Larsen.
Meanwhile, Berwick have confirmed the date for the Bordernapolis. The meeting, which is the traditional end of season individual, will be held at Shielfield on Saturday, October 23. Anderson said the club was already looking at riders to invite and details will be announced at a later date.
The Bandits will then bring the curtain down on their 2010 campaign with their end of season party in the Black and Gold on Saturday, October 30 when the 'Rider of the Year' awards will be made.
