Sole trader - bike as a tax write-off?!?

My dunce mind is slowly figuring this out. So if I want to be completely honest, which I do, I could keep the beater going and ride to work on that, keep the shiny new carbon at the studio and use that for meetings and work related travel, and then claim 70% of it back.

Or setup the cycle to work scheme for my company, which is apparently possible but more of a admin-ball-ache I imagine.

no. that's 70% if you only ride on 5 days for nothing but meetings.

just calculate how much of the bike use if for self-employed work.
