Id like to know if its at all possible to upgrade my 250watt standard hub to a 500watt hub
Yes it is Andy!
But if I was you I'd go for the 1000watt upgrade. Reason being, the 500watt motor is heavier than the 250watt motor, but not a huge amount more power, so that extra power gets largely eaten up by the weight. Also if I was to convert My wife's freego hawk again, I would just put on an entire kit! And not try to incorporate the freego components, it made the task much harder. To be fair though, I had a spare almost new 48v 13ah Dolphin battery doing nothing, so We only needed to buy the kit £130 eBay. The power now is fabulous, she didn't want more speed, just torque, but off course she got both, but she can wind the speed back anytime easily on the KT lcd3 if she desires. Photo below.
Good luck Andy
