My first thoughts after a couple of week's use:
• I can't usually filter up the inside of traffic 'cos it's 70cm wide, and when I do drivers get really shirty - much more than when I'm on a bike.
• If I don't keep a nice straight line & wobble a bit they give you much more room overtaking.
• Keep the electric assistance low when crawling along in traffic.
• Must try & remember to keep speed down so power assistance stays on
Did first job using a medium size step ladder today - it fitted on lid as planned though I'm already planning the next box to build. Probably a bit narrower, a bit lower & sloping down towards the front.
