Xavier Hopkins only has 10% vision but that hasn't held him back from sending huge gaps on his ebike. Xavier suffers from albinism, which causes too much light to enter his eyes and nystagmus, a condition that causes his eyes to shake uncontrollably. As such, he is unable to focus on things more than a few metres away.
In a comment posted under the video he explains how he was able to build up to riding such big feature. He says:
To top it all off, Xavier has only been riding for a year and a half and is already confident sending some sizable gaps. Hopefully we'll see plenty more of his shredding as his riding progresses even further in future.
