I believe its still 250 watts (nominal) in other States but I just read that the limit has been raised to 500 watts in NSW but the max (assisted) speed is still 25km/h. So will manufacturer's make a NSW only compliant 500 watt bike, doubt it and existing 500 watt bikes for off road use would still not necessarily comply due to the top speed etc.
Electrically power-assisted cycles
An electrically power-assisted cycle has a maximum continued rated power of up to 500 watts. This power output must be:
progressively reduced as the bicycle’s speed increases beyond 6km/h
cut off when:
your bicycle reaches a speed of 25km/h
you stop pedalling and the speed exceeds 6km/h.
Jaysus, 500w bikes will do 45kmh+ easily if hacked, i wonder what caused this.
Not complaining though, looking forward to getting dropped by granny's on their coffee rides.
