I fitted the rear rack, and the number plate issue is easily resolved. The number plate holder is attached to the mudguard by 2 screws, simply mount the holder on the rearmost screw only, and on the support arm, only screw 2 of the support bolts in (see pics) sorted!

I'm going to zip-tie the remaining 2 bolt holes just to be safe.

 No comment on the old but this is good, as my charger is a 10 Amp it does not fit in battery box. So got a big usb charger placed in batt  charger tray this gives me Sat nav access to Bluetooth in helmet music maps. Soco App does stats added iPhone to holder on handlebar  lead goes into battery lid right hand side. Laptop does not fit box so sling it over shoulder as a commute magic.  Just done a café run to Loomies on A32 near Petersfield Hampshire.  Battery in 2020 model believe same as all but speed is defiantly greater in 2020.  This means Electron feed is also greater so I started at 96% stayed in 1 to Shop 3.6 Km Then to Café 25.28 Km then home to Fareham 25.41 Km 3% left majority was in Mode 2 but never mode 3.  about 2 miles could be Mode 3 each way run this is 6,4Km so if 100% can do café run at national speed limit but just.
