Hi,
I live in an area that is very hilly. I was looking to buy an ebike kit and a battery to go along with the kit but it is beyond my budget at the moment. So, I decided to build my own ebike kit. I was thinking of stripping a brand new cordless electric string trimmer and using the motor to chain drive the back wheel. I am thinking of attaching the motor to a rack in the back. I would have to take the throttle from the stripped assembly and attach it to the bike's handle bar with a twist-on wire connector to extend the throttle far enough to reach the handle bar.
Here is a drawing I made of the setup:
I am looking at this trimmer as a possible choice for this project:

Is 40v enough for my needs? Will it reliably ride up steep hills without burning out the motor and making it unusable?
where can I get the chain sprocket that I would need to attach to the motor arm?
Which type of chain should I use?
Looking at the picture on that homedepot product page, it seems like the motor is within the trimmer shaft next to the throttle. Will it be compatible with the setup I want to achieve?
Thanks.
