It's been awhile. Time for an update. Finished my younger sons bike for the most part. Still tweaking a bit. This version of the bike is much lighter at 70lbs with 7.5ah 52v battery. It has smaller fork components more appropriate for a beginner kid. Cable brakes for now, 10" wheels, and...

Took the bike with us camping this weekend for my son to ride. He has been riding it around the house quite a bit and it has been solid. Still on the small battery pack and only 31A peak current measured. That is plenty for him as he only weighs 50lbs. Haven't finished the other bikes yet...

Just got home from vacation in Utah. I finished the first bike and we did some riding. Really satisfied with the power. I had to turn down the max current down to 35% on the Kelly to make it appropriate for my son who is still learning. The KBS controller I am using will do 100amp burst for 30...

Did some functional test wiring and testing on the throttle setup. Finished welding out another frame that will get an LMX motor in it. Same motor chassis and mounting pattern, just a lot wider. I will make a bracket to mount the hall sensor throttle box this weekend and get some other...

Have you tried powering the halls off the 12v port on the Kelly instead of the 5v port? I just solved an issue I was having with the GNG motor halls by changing the thin red hall sensor power wire from the motor side from pin 5 (5v source) to pin 11 (12v source) on the kelly. Motor runs...

Thanks guys. Yeah it's solidworks. I took one of the seats apart and shaved a ton of foam off of it to see how low I could get it for a smaller/lighter configuration. Should work well on the little bike with 10" wheels and light forks. Quick mockup, looks like it'll be perfect. First...

Wouldn't hurt to pull the cover off the motor and check the hall mounting. When I got my BHT motor I had to do this to get it settled into the right spot. The mounting of the hall sensors was not exactly rock solid on that motor. They just slid into grooves if I recall. I think they had a...

I powder coated the frame and misc parts this weekend and did a little bit of the assembly work. I have to get a few more hardware pieces, the controller, battery, and make some side panels.

Thanks! The swing arm is attached with a heim joint/rod end. They are very strong, easy to replace pivot components so I like to use them for this application. They also allow for slight front to back adjustment.

Did some more fab work this weekend and got the rear swing arm mocked up with a shock. Also made some parts for the other 2 bikes. A little bit closer. t4TRiaT_hb8

The frame weighs just under 15lbs. I hope to have the swingarm parts done this weekend so I can see it mostly together. Good news! I scored a free non-running ICE bike to pull parts from. Makes putting a second one together easy. I think a lot of people just run these bikes as far as the...

Well, back at it again building a few bikes. I finished my first e-bike in 2015. See it here. https://endless-sphere.com/forums/viewtopic.php?t=60191 It is still up and running. My original li-po battery is getting a bit sacked out with about 2600miles on it. Other than that, it has been...

I like what you have done there. Which controller are you using? Any issues with the voltage being too high for the controller or anything? Do you have to undercharge the battery? Interested in doing the same mod for my son's bike.

Tempting on the BHT, may have to wait to find out how this motor works out for you though! I really like the BHT for it's mounting format, size, weight, price, and performance. It works pretty well on a bike under 100lbs. I do want something that I can buy multiples of because I have several...
