Long story short someone tipped me off that some UPP batteries were causing fires. I had already planned to tear down the battery and swap out the BMS so hearing this I immediately tore down the battery to inspect it. I paid nearly $500 to get the best quality I could from Amazon. This was my...

I bought highest grade cable I could find. It was 65 for 20 feet. It's rated to 200C and 600V and the silicon is nice and thick. I'm gonna use it for phase leads directly to the motor too. I think I'm going to put braided stainless steel hose over the wire for even more protection. Ok I'm...

Wow I didn't know that. Luckily I haven't been using it yet. I know the battery I bought has high quality LG 21700 cells. I paid 500 almost for 48v 24ah. Anyway I have the top secret specs from LG testing the exact cells I'm supposed to have. They can take a he'll of a lot. At any rate the bat...

I bought a flipsky v4 remote. It has double action thumbwheel for throttle and brake. It also displays more info than a normal display. I'm going to take the guts out of the remote and machine my own cases / thumbwheel to put them in to suit them for a bike. But I'm running a vesc not a...

I have a G51 display that I can probably let go in the near future. I'm putting a Tronix 250R VESC on to replace my controller and I have a Flipsky V4 Remote - Throttle / Display combination. It is much nicer. For my G51 I never got asked for any code. In the display parameters you can set MPH...

What size are you looking for? Mine are 20 X 4.0. Amazon

With my battery and all I'll break one of those. You need to measure the seat tube with something. I use calipers and micrometers that are expensive. They measure very accurately. These are cheap but still good enough...

In case your wondering what the collar looks like. I modeled the bike frame today and designed the collar that will also hold my rear rack. I'm betting it could hold 200 + LBS. The rack bolts down to the collar, It also snaps in place so that nothing can move anywhere. If you guys need parts...

Yes, you can run 4 inch tires. But i would look for the thickest toughest ones you can find. My wheels are 20 X 4.0 and I'm running HEB Allacapes. I really like them and they are much more flat resistant.

Ok I've been thinking about good ways to leverage the VESC control system. I got a great Idea. They make gyroscopes that hook to the VESC for controlling the One Wheel operation. It measures movement in every direction. If I attach one I can program it to be a bike alarm. If the bike gets moved...

Yes. The one I had was in free air off the seatpost. It was rated to carry 25lbs. It snapped off after about 100 miles. My battery is less than 10 lbs. It was just a temporary setup anyway until I could machine my own. My design will hold my battery and my electronics and also serve as a...

Ha ha ha ha. Lol If your old like me you'll get this. If not you won't understand. But Damm I remember back in the day when they thought this was high tech. LMAO.

It is the force of wind resistance that influences the power level. The wind resistance is adding way more drag than the motor in either case.

Just make sure if you use the VESC that you use the 3.3V line for the switches and throttle. Not 5v. 5v will damage the pull down resistors on the board. The white wire currently is used as speed sensor for bafang control. I'm going to use it to install a temp sensor in the motor. The VESC...

What i plan to do is use a hall sensor and magnet out of a throttle. Put them inside a little case so that the brake cable attaches to it and activates the sensor. This way when you pull on the brake lever it reacts like a throttle. A large spring can be attached inside to create resistance to...

I like the way the plate acts as a fender. I had a rear rack that was bolted around the seatpost and then has an aluminum pipe coming out. It doesn't attach to anything else which is good for me cause I have rear suspension. The rack is rated to hold 25 lbs. I had my 10 pound battery on it and...

Im thinking of doing the same as the phaserunner. We can code into the VESC and program it to give us the freewheel effect. I am also going to use a Flipsky Remote for a skateboard that has forward and reverse built into the throttle. The forward motion of the Throttle will control the level...

Have a great time. Just let me know anytime. Really I plan to start machining a variety of parts. I have the equipment and tools to do it, so why not.

Yea I'm pretty sure it just cuts the current off. And yes you would loose brake. I'm gonna end up running regen braking and my front disk brake. I'm gonna end up loosing my rear disk. Got to make room for 8GA phase leads and cooling lines. So like I said, you either charge the battery full...
