.... If motor choice is relatively open, retaining the gearbox is a very inefficient choice.
it's an extra cost to manufacture - but not inefficient
(consider some EV makers do use a gearbox - and eg the Tesla 3 is 'only' 80% efficient)
in this case there's already an automatic transmission
£25000 is the starting rate for a conventional ie non-DIY conversion

less energy recovery than ideal
the 'trolley-truck' concept has quite poor efficiency - because the line losses will be high (c.10-15%)
due to the necessarily rather low voltage/high current and the lack of rails for the circuit return-side (its not a tram)
so no better efficiency than a BEV equivalent
