I just bought a tw200 Yamaha enduro to convert to electric. It came with a 16hp , 11 lbs torque motor . I would like to find an equivalent. Would prefer a hub motor but if I need a mid drive I will, any suggestion on motor and controller , I’m thinking of making my own lithium cell setup. I don’t need any faster than 45mph.

Do you know what to do building your own battery, its not easy and if you have no experience or knowledge its a huge learning curve.
You going to use RC Lipo, Prismatic cells, 18650's, pouches. What voltage do you want, what speed do you want, what power do you want, 1hp is 750W, so 16hp is what???? 7500+3750+750 is what???? 12000W
What you going to be riding terrain wise, hills, jumps, water, creeks, dusty, desert, mountains, oceans, valleys, space, mars, uranus
Schedule a test ride on one at zero motorcycle dealership. Ride their bikes make it your baseline reference point cause chances are you dont know what goes into a fancy bike like that so ask questions answer the above person s questions for your self. There are options pmac motors to bldc hobby line (no regen with bldc motors And build one like it or you can buy pices of used electronics and put it together your self (not recommended). I suggest a kit $2000 -$3000 batteries not included. Use lipo there best chemistry. Tedious tho should you not use a bms. Just keep them at a safe voltage. ie 20% voltage should be considered dead battery and time to recharge. Better yet if a cell fully charged is 4.20v then low batt is 3.8v +-.2v.

That is in the wrong section. It should be in https://endless-sphere.com/forums/viewforum.php?f=10
I don’t recommend a hub, and mid drives for that bike are motorcycle domain. You could check for a used Zero motorcycle motor and drive parts. I guess this might be pretty easy to find.
Good luck with your build.

If you Choose a Hub motor you’ll have more room for batteries likely adding distance. Another good way to plant the motor is on a fabricated swing arm might change the ride quality but you’ll need room for batteries they make or break the build literally sometimes 
. Either way it will be a fun experience. Post pictures before and after and along the the way. I like to learn

Shame to ruin one of those, unless the motor is broken. But an electric one would be fun too.

Dman is right!
The TW200 is, and has been a very popular bike. The fat tires make it a foo-foo bike in soft terrain "par excellence".
Plenty of junk motorcycles lying around that don't have the value (even not running) of the TW200.

Yep, the TW200 is an excellent motorcycle, I ride the narrow tire version, the XT225 and it's a great MC too. It would be a shame to try to make an electric MC out of something so nice.
There is a TW200 forum, not on ES, the members meet every year in Moab for some great riding. If I had a TW I'd keep it pretty stock and ride with them.
Look on Facebook Marketplace in San Antonio, TX, there are two really nice mountain ebikes for sale. One is a Canondale, the other is a Bafang Ultra Beast. Both are full suspension, mid drive, and use torque sensor pedal assists that really work well. The Bafang also has a throttle, it is not a BBS02 or BBSHD Bafang mid drive, rather it is the Bafang mid drive that mounts in a frame that is made for it. I mention these because I'd love to have either one. Either would ride better than a TW converted to electric.
I'v see electric motorcycles at MC races, these were demo bikes. Our son has ridden them on the tracks he races on, his opinion is very favorable.

It looks like a decent basis. Could you put some pictures of your actual bike so I can see how hard it would be to fit a hub motor, especialy the swing arm?
Nothing wrong in using hub motor on a motorbike, it has been done a lot of times and it works very well. It can easily outperform the original gas bike, by far. 45mph will be easy to reach, and given this low figure I believe your expectations in terms of power aren't really high... so you'll probably be surprized!
You didn't mention any budget, so I'll propose you a setup that I believe is affordable and provides decent power. Get a QS hub motor, at least a 3000W, preferably 5000W, and if possible with the aluminum rim, not the ones with spokes (they heat more and they are less reliable).
For the controller, you should be happy with anything having more than 150A battery current/350A phase current. That won't be crazy powerful, but probably more than what you think currently. If you want a decent setup and you have a few more bucks to spend, try to go over 200A battery/450A phase.
I can't really recommend any brand since quality is always unconstant. I personnally like the Sabvoton controllers, but recently people say that they are less reliable, so you could also consider other manufacturers like Kelly, Mobipus, Votol, YuyangKing...
You'll also need to make sure your battery will be able to supply that kind of current.
Anyway, please describe better stuff like your budget, and intended performance, it will be easier to help you.

Except you can't actually install it.
The swingarm won't fit the chassis without very extensive modifications.

And a 12" scooter wheel and tyre won't work for the bike!Dui said:
How far or how much time do you want to ride for between charging? What kind of riding is it? What terrain also, hills, sand, mud, grass, hard tracks? All are important.
