I am very impressed with your skill and the quality of your workmanship. Apology if this has already been answered, but what is the range?
Not a straight forward answer I'm afraid. It is capable of doing about 65km on a full charge. But that would be on a flat road and cruising at 50km/h the whole way and not using too much throttle. Realistically, with hills and the occasional quick acceleration away from the lights it's more like 45km if I only drain the battery to ~30%. Not draining the battery below 30% is the best to preserve its health.
I have a 30km cross Auckland commute that is possible to do by avoiding the motorways and staying on 50-60km/h roads. The battery won't get me there and back but I have just bought a 2nd charger that I will store in the office. I won't use it for that commute very often but when the weather is nice I will.
