I'm looking at converting a bike, with a Bafang HD motor. I'm looking for a reputable dealer for a kit. Need motor, battery, Hall sensors for brakes, gear sensor etc. Is there a go-to source? My brother turned me on to this but bought from Amazon, which not an option.
I've done a couple, but I did buy from Amazon for the cheap stuff. Grin technology is the best, but you will pay for it (also they are in Canada, so shipping).
I've gotten other parts from places I thought were more of a shop, but it all comes down to some ebay/Aliexpress joint in China eventually.
Where are you located? Check out Endless Sphere for all the info you could want.
I can't recommend doing the E-Bike conversion enough. riding it leaves you with a stupid grin nonstop. Also happy to help if you want to try building your own battery, but after a few years of that I'm loving just using tool cell battery packs.
Final thought, the Bafang is the most common and can give you the most power, but if you want it to feel like riding a normal bike (but with superman legs) you want a torque sensing motor. This vendor is one that seems like a step up but I've never used them.
Watching because I have a old BMX size Schwinn stingray I would love to convert if it's affordable enough...
So... Daniel... can you point me to a mid drive pedal assist setup for my polygon siskiu t8?
I'm intrigued, but not enough to drop 1500$ doll hairs on it.

Thanks for the reply and links.
I've only ridden my brother's bike with Bafang HD + Alfine 8 (which is frighteningly fast, as in, 40 mph and pretty wicked acceleration), and my wife's ... wait for it ... Harley Davidson with an Enviolo CVT (not impressed by the shifting and it'll only do 11 or 12 mph uphill). The Bafang seems like a pretty easy solution but I'll check out the links.
DIY battery would be less expensive, need to do some research...

Some Things to consider:
There are 3 kinds of E-Bike conversions.
front hub- easiest and cheapest to install, least “regular” bike feeling. Needs old steel front fork of above 350W.
Rear hub - a bit better balance, keeps the front wheel light. Highest power possible. May cause driveline issues.
Mid drive - most effort install. Need to be able to remove crank and replace bottom bracket of your bike. Allows your gears to work with the motor. Lightest weight. Lower ground clearance.
you need a motor, controller, battery, and interface. Most mid-drives combine the controller inside the motor.
How much do you care about the bike looking stock, wiring being hidden, or following whatever local limiting laws are in place? Are you ok with a rack to mount the battery, do want it to be in the triangle, or like a water bottle, or hidden in a bag?
voltage differences:
36V - cheap. good for endurance, not speed. Ryobi 40V, kobalt, greenworks, series up a few dewalt, Milwaukee, or ryobi18-20V packs.
48V - most common in E-Bike batteries from china, no common tool pack I can think of.
52V - probably the best balance. Ego 56V
72V - most speed, most cost. Kobalt 80V
Many controllers can work with 36-52V, but not all can.
