Yosepower 350w Lishui. Change controller, or change to mid-motor bike?

[a573245325]

I have a Rockrider ST bike with a Yosepower 36V 350w hub kit. I'm happy with the power, but want more of an assistance rather than a speed feel. The controller is a lsw1599-3-5m.

I had thought I need to get a different bike with a mid-motor drive and torque sensors, but then I read about KT controllers.

I have 2 batteries so I'm sticking with 36V for now, but may want to go up to 48 at some point. I may also change the hub to a 250W one to be legal. I found the T09S and T09P. Do I need sine or square wave, and is this controller too big for my motor? Or am I going down the wrong path?
Cheers.

Sine wave is better in most circumstances. The 250w version gives more power for speeds up to the legal limit and would also be better for 48v because it has a more appropriate Kv.
