not cars , electric bikes, but the principals might be relevant
i was an early adopter circa 2007, got a pair of whisper, top end ,off road and on, could carry me and 40kg or ten chickens pretty well over a muddy field or pootle along a flat route with little or no pedal work.
20 mph with little effort =ten miles, the batteries were a bit carp and expensive to have 2 for each bike
very robust in some ways ,bit of a lump in others rather like a mk1 landy
i have seen photos of them converted to 3 old car batteries in a trailer hauling a peasant and half his farmyard across pretty rough tracks in the far east
nice and long-lasting if a bit basic and limited, a grand purchase but getting to the unmendable at a decent cost stage
the new ones are about 2 yrs old and very different.
haibike, mountain bike style, top end engineering, batteries, motor and control gear
they need to be pedalled for legal reasons but the odd tweak can make that a far better experience(no comment)
range/rate, i am not sure, half a full battery was about 20 miles in about an hour without getting an old man tired
it handles like a class b rally car (post tweaks) and is ace off road or in urban use
not a landy and it does not handle loads as well as the last one but that is not its role, it can shift shopping or 50 rose bushes and a pick though
the two are different styles but the technology of the 2007 compared to the 2018 is as mk1 to a quattro A2
if cars have followed a similar development curve the newer ones might be a very pleasant surprise |

e-bikes are really, really developing well, weights have come down and range has increased.
some compromise between tech and components though. lower spec ones are rather lacking in the brake and gearing department.
Also needs some standardisation to be introduced. (this also should apply to EVs in my opinion). |
even modern low spec are not as good as the whisper, we were lent one while one of ours was being fettled, total joke of a thing
re weight , the new ones are not much lighter than the old ones unless stripped to basics but i like comfort and a decent rack, i rather like the front and back disk brakes, the old one was front disk and rear caliper which could be a bit interesting on downhill stuff, both of us nearly died of devon hills
they do have a far better power to wt ratio though for the same nominal motor power and the tweaks make them far safer in urban traffic
back to cars if bikes are anything to go by, top of mid range and made for the tasks you require it to do should be very pleasant
if you like drifting etc there will be a car for you:roll:
some of the things i do on bikes are based on using old school east euro and brit motorbikes off road for quite a while adapted to these things,
on road tis pedal style but with an atomic postman rider doing the pedals:lol:
an electric quattro e2 peaks version would be fun but sensible is probably best
i recon with a safeish route and not much to transport many folk could do most of their journeys on a leccy bike , some journeys and loads need a bigger machine |
