LaFree convert pedal assist to throttle.

Hello everyone, A few days ago I bought a LaFree E+2 Electric Bike and it is pedal assisted however I would like to convert it to a throttle if at all possible.
As much as I enjoy the exercise it'd be nice to go to work everyday without being sweaty :lol:

So I'm asking you guys is it possible to convert this bike to a throttle assist?
And if it is possible, what are some good throttles to look at buying?

Thanks in advance.

I have not pedaled my ebike in months and I ride every single day!

Yes anything is possible, but is it easy, we will find out because some ebikes are proprietary where they lock you into buying their components like battery, motor and controller. First we need to find out where the controller is, it maybe in the battery, it maybe down by the motor or its in a box on the frame.

Any throttle is good, I buy from Greentime on Aliexpress, they are good.

Choose the perfect pedal-assist mode as you ride, or simply select our proprietary “Auto mode” setting that automatically adjusts the motor support to the terrain.
