And who knows how much skin he has left behind on the tracks and roads around the country.
But it will have all been worth it if he can get on the podium at the junior world track championships in Italy in August.
The determined 17-year-old Taieri College pupil has been selected in an 11-strong New Zealand team which will contest the championships.
The promising cyclist is following in the footsteps of Greg Henderson, who also competed at the junior world championships.
"I'm the first one from Dunedin in quite a while.
"I think Greg Henderson was the last, and that's going back a wee while," Evans said.
Brad took up cycling when he was 11 but was always likely to end up in the saddle with both his father and grandfather keen cyclists.
"It runs in the family. There were also lots of people my age starting cycling at the time."
He played tennis and basketball but found cycling more appealing, and prefers track to the road.
"It's more exciting," he explained.
Brad has been named in junior New Zealand road teams but is concentrating on the track at the moment.
He is the junior New Zealand pursuit champion and his main events are the individual and team pursuit.
But he will also contest the omnium at the world championships.
The omnium is a new event and it `is "like the decathlon of cycling", he said.
It is five events across "four or five days" and suits all-round riders like Brad.
He is extremely ambitious and wants a medal.
"We've got a really good chance in the team pursuit," he said.
Brad is ranked in the top 20 riders in his age group and needs to trim about 6secs from his best pursuit time to put himself in contention for the gold medal.
"I can definitely get my time down," he said.
"If the guys can all lower their times then we are looking at doing very well in the team pursuit."
Ultimately, Brad would like to ride professionally for a team and, of course, in the Tour de France.
It is a lofty goal but it is why he spends most of his spare time on his bike training.
He trains about 20 hours each week.
After school he also helps out at his father's cycle shop and does some part-time work at a Mosgiel pharmacy.
Some of those funds go towards buying new gear but the "the bank of mum and dad" covers most of the costs.
He leaves for Italy in mid-July and needs to raise $10,000 for the trip.
The championships begin in mid-August.
