That's average, not max. You need at least 50mph capability to be safe and avoid being the recipient of road rage - I think max limit around London is 40mph and you need a bit extra to be able to manage that.

Cooling isn't an issue at home charging levels, but does complicate any removable battery concept.

I did some homework before posting my OP, batteries are ca 11kg ea 2 off

Really? According to the WIkipedia article, which may not be accurate, the weight with batteries is 60 kg more than without (5.5 kWh battery, haven't looked whether they had versions with less capacity and thus lighter, but if so, that's probably not going to get you very far). So, hmm. What's up with that.

Clearly not a residential London Ebike commuter (as I, for 2 years 11 mile trip challenging Trafalgar Sq every morning What a buzz)  on my crappy 8spd Mountain Bike, my biggest fear was goddamm pedestrians, walk out in front of you - they dont see bikers - and think they have right of way. They caused the only 2 accidents I had and threatened to sue me for walking out in front of me. :box:

Lion batteries energy density ca 250Wh/kg  so 5kWh is 20x  ie 20kg  = 10kg/battery pack (say +1kg for casing)  OK  so Im not far out with my HOMEWORK :-DD.  Thats easily manageable as a carry out.  If I still lived in central London its what I would do :-DD
HACK IT HACK IT - Keep a spare pair indoors and modify to use Anderson Connectors.  Probably keep another pair on board for extended range should it ever be needs.  Perhaps and enterprising young fella will open a little swap shop for Ami owners in Chelsea   Kings Rd Also renting out the trendy Ami Safari
