Thank you! I'm trying to find Samsung 30Q's at a reasonable price. They're pretty much sold out everywhere.

Please delete and recommend a better location if this isn't the right place to post this. I'm looking for a source for good quality cells to build a pack. I'm looking for authentic Samsung, or sony or the like. I've seen them on Aliexpress but I don't know if they're legit. Shipped to USA...

I just got a motor and controller from them about 3 weeks ago, ordered on aliexpress, shipped to Montana.

Hi! After spending years on this site and building converted ebikes for fun, I have decided to start an ebike rental business in my area. I live in a very toursity area. My sisters came into town and I went to rent an ebike for the day, and they said they were sold out for the rest of the...

Dude, you are so helpful. Thank you! I did a search on here but didn't get the links you posted. Cheers!

I love the idea of having some vintage looking analog dials on an ebike, giving information like Speed, Temp, Voltage, (battery capacity?)etc... I don't really know how to do that, however I did find this cool youtube video of someone taking an analog voltmeter and converting it to a...

Thanks everyone for the great advice! I'll start a thread when I get going on the project. I think I'm going to start with just regular cold rolled 3/4 or 1 inch .06 wall tubing and do some practice bends and welds. As far as strength goes, it's probably strong enough, right? I mean if...

Thanks for the advice. I'm the guy in the other thread asking about a beginner custom frame build. Your comments were helpful with understanding what I need to do to build a frame from scratch. I have already ordered some 20" bike tires, but I feel like with a qs205 I need something a...

Hi I'm looking for a good place to source moped rims/tires shipped to the USA? I'm looking to build a fat tire type bike, so as wide as possible, size 16-17. If anyone has any recommendations, I would appreciate it! 8) Thanks

Hi! I'm interested in building a fame for my ebike build vs converting one. But I'm not sure where to start. I've watched several youtube videos, and plan to make a simple wood/metal jig. I plan on tig welding it, and want to use cromoly tubing. I'd like to make it similar to this style of...

Can you explain "lowest level components"? I think you're saying occasionally check each individual pack with a volt meter. Any suggestions for a decent 20s bms?

Hi all, I'm trying to resurrect an ebike project I had running years ago, and have some questions about getting a BMS going. Please forgive me for asking a dumb question. TL;DR: I'm building a 20s2p pack out of turnigy 5s. Do I use 8 5s BMS boards, or two 20s BMS boards? My aim is to...

That's what I thought. Thanks.

So if the switch is between the two packs, vs at a main connector on either side of the pack does it experience a different amount of current? Does a switch at A, experience less current than B? Thanks.

Right, so there are a few ways that I have considered to make this process more failsafe. I thought about making a plastic plate that had 4 bullet plugs on each corner sticking out perpendicular to the plane of the plate that would act like a 2 pole switch. When you take off the plate one of...
