A FEW centimetres' difference in how he landed and Michael Blyth would have walked away from a mountain bike stack unscathed, rather than never walking again.

A few metres difference in where he fell and the 18-year-old may have been eligible for TAC compensation so his family could help care for him, rather than facing life in a wheelchair without financial support.

Instead, Mr Blyth's May 25 crash has left him unable to walk or return to his family home, which is not suited for wheelchairs.

Riding on council land on the outskirts of Sunbury, Mr Blyth crashed going down a ridge and landed on his back, severing his spinal chord.

Despite his tough situation, Mr Blyth is determined not to let becoming a paraplegic define his future.

"If I had crashed on top of the ridge, rolled a few metres then fell down and broke my back I would have had full (TAC) coverage," Mr Blyth said.

"But because I had my full-face helmet on, protective neck brace and all mountain bike gear I was intending to go down there."

He is not eligible because he was not on a road, and intended to ride down the ridge, rather than accidentally falling off it. "I knew straight away something was wrong. I said to my mate straight away 'I'm paralysed'," Mr Blyth said.

The Sunbury and Gisborne communities have come together to raise money so Mr Blyth's family can alter their home.

As he continues rehabilitation at the Royal Talbot Rehabilitation Centre Mr Blyth is determined to return to his passion and work in a cycle shop.

"I will still do as much as I can. I am a music producer and I will still do that, I will still be involved in the bike community and in the bike shop," he said.

"I had my stack, but I wouldn't want any of my mates to stop bike riding. If I wasn't here today I would be out bike riding, this doesn't change my perspective on it.

"I'm a strong believer that a cure will be around one day. It will happen, but we have to live life the best we can in the meantime."
