Hello everybody, About a year ago I've proudly finished my first E-Bike build and apart from some minor issues that I could fix myself everything went smooth. Now the Hub-Motor does not work anymore. I bought almost everything from EM3EV, it's a 52V System with a infineon controller and a...

Hello, I finally finished my first E-Bike Build. Maybe I'll post pictures later on. While everything is running, I have one concern. For my build I used this Bike, with an aluminium frame (the largest size option): https://www.fahrrad.de/cube-curve-pro-limenblack-540066.html I run a Mac 10T...

That's nice to hear. I will carry 30 A at max (probably even going to limit it to 24 A). I asked about bullet connectors because I can buy an extension cable, so I can save the soldering for that part. My soldering skills are average and I have never crimped before, so I hope the Hall cable...

Thanks, the keyword scooter made me find these type of connectors, here in Germany on ebay. BTW is it bad to have two connectors between motor and controller (on the phase wires) ? Is there a lot of resistance in banana connectors ?

I would like to buy an extension cable with connectors, that are referred to as "Molex", in the article below. http://www.electricbike.com/connectors-halls-throttle-motor/ Unfortunately everything I can find, if I search for Molex are these...

Thanks, that was it. I thoughtlessly mounted the brake sensor without mounting the magnet. :D

It's directly pluged to the controller. Thanks, will try.

Hello, I'm attempting my first E-Bike build and just finished the wiring. Unfortunately not everything works right away. I hooked up all the connectors to my Infineon Controller, the switch to power the system up works, as I can tell by the CA also working. When I turn the throttle the motor...

Hello everyone, I have some questions concernig this Batterys: 1. https://www.aliexpress.com/store/product/US-EU-Free-Tax-Sanyo-GA-cells-Electric-Bike-down-tube-51-8V-1000W-power-li/1178407_32742079788.html?spm=2114.12010612.0.0.4526ab7344fx8N 2...

Thanks for the info. Does that mean that if I run a 84 cell system with 14s6p and draw 24A, I need to upgrade the connections because they can't handle 4A continuous? I'll use these cells: https://eu.nkon.nl/rechargeable/18650-size/samsung-inr18650-35e.html

Hello Everybody, Does one of You have experience with the vruzend battery kit ? If so, how much efficiency do I lose compared to spot welded battery packs, e.g. how many meters per km? Thanks Felix

Hello Everybody, still in my quest to build my first E-Bike, I'm now searching for a downtube or triange battery case. Unfortunately I've just found cases that keep 65 cells but that's not enough. Are there any cases that can take 70 or even 84 cells (lockable if possible)? Thanks in advance Felix

thanks, I just want to make sure. What speed would you recommend for a 1000-1200W system and 28er tires ? What speed does the MAC 10t have ? Why is more load placed on the controller if the rpm are higher ?

I don't mean to be intrusive but it's been 4 days since my response post. Maybe someone is willing to help me a bit further.

I understand the difference. I mean cassette. I happy to hear that but my bike is made out of aluminum, of which I heard that it's hard to stretch without breaking. I thought about this one from EM3ev: https://em3ev.com/shop/6-fet-irfb4110-infineon-controller/ As f up german law can be, with...
