Commiserations about the crash and the sad consequences. But here's a positive note.
Quite a few years ago now, I followed a rider into the carpark and discovered that we were parked next to each other. We were both putting our bikes in the back of the car and both removed our front wheel. I wasn't watching him, just aware out of the corner of my eye. Then I noticed that he put the bike in the back of the car with one hand! (pre emtb!) Intrigued, I commented something like "Bloody hell, you're strong!" or something inane like that. He turned to face me and I noticed that he only had one arm! I was embarrassed, but he quickly said "no problem mate!" ..etc. I asked how the hell he was able to ride an mtb with one arm and he promptly lifted the bike out and showed me that all of his controls were on one side. Unprompted he told me that he was about to saw off the unused side of the bar! He said that when he came off, the bar poked him in the gut and he could do without that!
He'd had to boost his upper body strength and that of his remaining arm, but that was all it took. (ALL! - he made it sound so easy!) I was gobsmacked and full of admiration at the same time. It shows you what we are capable of.
You can do it
