These are great scooters, I have the Vectrix VX-2 and they share the frame and most of the body panels, motor etc. mine only has the sevcon controller.
They are a little bit bigger than the average scooter, great road handling, comfortable, original battery weighs a tat over 100 kilo's (48V 60Ah Lead ) And i personally replaced it with 4 Volvo v60 Hybrid units in 13s config giving 90 Ah, so, 1\3 of the weight and 1,5 X range, which is now +/- 50 miles @ 42 mph ( got the top speed tuned a bit, rest is stock ) If I would live in the UK, I would be all over it for 395,- pounds, bargain price really for the quality you get.
Pulls very fast drawing 8 kW to 30 mph, motor is always cold, even after a spirited drive through the city, could take 10-12kW with ease with the right controller, QS one sided "4000 watt" 13 inch motorwheel.
Battery compartment is very big, if you would use 18650's, you could fit a 250Ah 60 volt pack with ease for a ridiculous range.
