Looks good, also unsure why you're using a tri-lobe cam though?

Hopefully by slowly releasing power to the flywheel on spin-up rather than direct-driving an axe the beetle's motor won't be in danger of stalling, the damaging part will be when the motor brakes, but no problems just yet (though not run near full speed so far..)

Bike cable should be here tomorrow, will put up a video then
