Finally got it just about right with the battery rack rotated forward as much as possible, a silky smooth Suntour suspension seat post to avoid back pain and a Satori handlebar riser so I can now see more of the wonderful views instead of mainly the front wheel!
Twenty seven gears for when I run out of battery power, Pannaracer Fire XC Pro tyres for the rough stuff, Hydraulics and 203 front rotor to slow me down and an upgrade to bigger DMR V8 pedals for riding in boots.
Thumb throttle only Cyclotricity kit with voltmeter and kill switch on handlebars.
Main usage off road tracks and paths.
