I built a homemade ebike with a 1800 watt Vevor BLDC motor kit. This homemade electric bike is chain drive, with a brushless motor and 33 amp controller. All the original gears are on the bike, so you can ride like a normal 21 speed mountain bike but with a big boost.
Top speed with my battery and gear configuration is about 35MPH, it can go faster with some easy mods to the battery and motor pinion, but I ride normally at 30kmh top speed when using the motor.. I will make another post after some mods, if people watch and enjoy the video.

Range of this ebike is limited about 24km 14 Miles, because I'm using four 12v 10Ah SLA batteries. I need to upgrade to a lithium ion, Lifp04, or lipo battery, but as of now cost is an issue right now. The bike and most materials were free, I was sent the motor kit for review,
I had the SLA batteries and paid about 24$ a piece, chain, sprocket and free wheel was about 30$. Why use a motor with chain drive, in my location hub motors are very expensive and the used hub motor kits are not available or the shipping is ridicules.

I understand not everyone can weld, you can mount a motor on a bike without welding. I only weld to make quicker and stronger builds, You could use steal slotted metal, the flat stuff with the holes. Also U clamps or exhaust clamps work well, round all with machine screws or self tapping screws. You can even use wood, the sky's the limit, If you want me to build one let me know in the comments.

Another bonus of a chain drive motor, with a lot of hub motors you with lose performance due to magnetic drag, depends on if your hub motor has a clutch or not. I can't have regen on this bike because I'm using a freewheel so the motor only engages when I apply throttle. I do not recommend building this, do not build this at home. The bike was driven on very quiet privet roads. This video is for edutainment purposes only, follow all local requirements.

Big thanks to my Subscribers! I have more projects planed, not just ebikes. Sorry I don't get into the comments very often, most of my allotted YT time is spent making these videos, and filling out everything. I don't get much of a chance to log on, but I really appreciate your comments and feedback. I do try and read comments while I'm posting a new video. If you have anything you want me to add in a video or projects you want me to try and build please leave them in the comments.
Peace
