Thanks EVTodd, I forgot about posting some completed pics. It came out real nice in the end once I found some suitable shifters and got the brakes connected. It rode beautifully just like yours and I guess since it was a low power setup I felt no resistance from the motor when not on power. I...

here's a link to EVmadrid's video perhaps you can see any difference in the one he uses and the one I bought which might explain. There appears to be a component next to the solder pads I pointed to which mine don't have. https://www.youtube.com/watch?v=py_LKc1Zt7w Mine is the top pic and you...

Hi there. I've installed a voltage meter like EVmadrid uses on some of his packs. I'm running mine on the handle bars cause I don't use a BMS and I'm also pulling power off the wire for a front light. Anyhow I'm wanting to change the default setup to volts instead of percentage but it doesn't...

Thanks for your input d8veh. I checked out those controllers you mentioned and I noticed they had two model lines. One was Sine wave and the other line said square wave with some kind of torque sensor simulation programming. Any guidance on those would be appreciated. For the moment I'm running...

Finished my battery quick release holder with some paint and straps. Bought some Velcro, one inch webbing and a couple of buckles to tighten it down. Routed the straps inside the bag for a neat job. Overall I'm quite happy with the result. I can fit 4 Lipo hard packs for a total of 10Ah. It's a...

Added bumpers to keep the packs centred. I think a combination of Velcro under the bag in the centre recessed area and cable ties will do the trick. The Velcro down the middle will fill up the recess created by the angle aluminium sides. It's something we used to do in RC boats to keep lipos...

A little more work on the battery holder rear rack situation. If you see all the bikes I've owned and built you'll understand that I like tidy bikes. The battery holder bag is something that I want to be easily detachable so I endeavored to make a tray that the bag will be attached to that clips...

So here's the type I have on the bike, it has the same red green black wires and plug as the throttle cable. I suspected all along that it runs parallel inside the controller which led me to ask the question at the beginning of this thread but not entirely sure until I open up the controller...

Thanks for both of those suggestions. The RC filter is a cool idea and the existence of a voltage type PAS sensor is news to me. I'm going to have to test my PAS sensors now since there is a fair chance it's already voltage based. I checked out this thread...

Thanks for the replies. Its a relatively inexpensive conhis motor and controller. Originally 200w 24v system. I'm running 8 cell so 29.6 v. Doing the math I must be around 250w and approx 8-10a continuous. I built one the same prior to this bike on an old Chromoly GT and my friend just had to...

It appears to just be on or off with movement without any modulation in between. It's not smart enough to see slow pedaling and adjust the throttle accordingly. I've read elsewhere if I remove magnets I'll just increase the initial start-up delay. I might have to bust out the multimeter and...

I'm building up a super cheap little 250 watt commuter setup with a Conhis front motor and controller. It is a pretty rudimentary setup and the PAS crank sensor appears to act like a full throttle switch. I don't really like that it goes full throttle with crank movement, would prefer to set...

The quality of the BMS circuit balancing and the LVC threshold could also be behind unseen cell damage. In an effort to squeeze as much performance out of the battery as possible they might be setting LVC too low from the factory. I looked into buying BMS circuits from OEM suppliers in China...

I've been using rc Lipo packs for a very long time prior to eBikes and have treated them pretty harshly with high discharge and high g force crashes. I used them in RC 1/8th scale on-road cars, buggies and rc boats. No fuses. Had esc's short out and go up in flames. The treatment we put them...

Hello there, this project (not quite finished yet) is my second such retro-mod build onto a vintage mountain bike. I find the quality of old chromo double butted frames is something you have to pay good money for nowadays but you can get them for next to nothing if you don't mind doing a bit of...
