Road Bike Conversion

[conv-fused]

My wife currently rides a mountain bike which I converted for her a few years ago 36V 250W
She now would like me to convert her road bike, I was looking at a rear wheel conversion from BMS battery. Wheel size is 700C, I was looking at the Q100C CST and using the 36V 10aH battery from her mountain bike which could be swapped between the 2 bikes.
Obviously I am trying to keep it as light as possible, the kit will only be used for pedal assistance.
What are peoples views on the best parts to use for this, do I get the Q100C CST kit, or is it better to buy it and the controller separately? Would it be better with a Sinewave Controller?

Any suggestions appreciated

Sine wave definitely!

The information on the website isn't very clear
Is the best way to buy this kit and then get a Sine controller?

Best to send them an e-mail and ask what controller it has saying you want the torque simulation sine wave one.

a GSM kit from Woosh is perfect,I have one fitted on my aluminum road bike.
