My attempt at lightweight, torque based EMTB

So Im redoing this thread, too messy in last attempt.... Ive lately starting to get interested in single trail riding, and have 2 bikes equipped with tsdz2 motors. One fatbike for the easy rides, and one full suspension Liteville for going up the steep stuff, and trying to get back down without brea...

Re: Phaserunner on a Cyclone 3000W

Before you change the controller, you can first just try setting your minimum throttle in the CA3's Throttle Out menu just a hair above what it takes to activate the motor. I think that messes up the Torque sensor feedback that i use for my main input. If I remember correctly the throttle overrides...

Re: Cycle Analyst V3 preview and first beta release

I thought about trying to duplicate an electric freewheel with a CA using a PAS sensor attached to the wheel hub. My thinking is to lock the pedal assist power to a small value just enough to keep the slack out of the drive chain and have it use that value when my hand throttle is at zero because i...

Re: Cycle Analyst V3 preview and first beta release

Is there any reason why the "electric freewheel" feature that is inlcuded in the Phaserunner controllers is not implemented in the Cycle Analyst? I cant see why it should not work (except memory space, perhaps?). It would have been a HUGE driveability upgrade to basically all mid-drive sys...

Phaserunner on a Cyclone 3000W

Anyone use this combo? I found a few threads about some problems with hall sensors, but no conclusion on those threads. Is anyone running this combo succesfully? Reason I want it is the "electric freewheel" setting. Im already using a CA v3 to tame the seriously jerky stock controller, whi...

Re: My1018 brushless alternative?

Did a test run today to compare the efficiency with the tsdz2 I had installed before. It was empty 7 km from home, even if I tried to be economical the last 50% of the ride. Definately a lot thirstier, unfortunately. So compared to the tsdz2: Pro's: -Ground clearance -Less resistance when battery is...

Re: First test on DIY ebike running slow and hot

The motors I have installed gets 40A bursts all the time, no problem.

Just to summarize - you have 2 indentical motors that you connect directly to the battery and there are no load on the shaft of the motor And both draws 19A? Are you 100% sure the current measurements are correct?

Re: First test on DIY ebike running slow and hot

Motor should not draw more than a few amps if connected directly to the battery and unloaded. Was it unloaded when you did the measurements? If it was, it sounds like theres a short in the motor.

Re: KTM 200 exc goes electric

Yes, I think you should leave "battery residual capacity" alone, just charge the battery and set it to the same value as "battery physical capacity". There might be one more setting that can apply to this if it keeps jumping around. I noticed a setting "SOC Auto calibration ...

Re: First test on DIY ebike running slow and hot

You could try to connect the motor directly to the battery and measure the no load amp to rule out the controller being at fault. Just be careful, it will start pretty violently. I have installed three of those motors (just the 800w versions) on different kids toys. It pushes 50-60kg without heating...

Re: High torque motor at 0rpm (stalled)

I am by no means an electric motor wizard, but I do have an electric power steering system on a race car that is stalled a lot of the time without burning up. Its a really simple system with just a 0-5v signal from a torque sensor controlling a brushed 12v motor via a programmable syren controller. ...

Im looking at making a diy torque sensor, low power (5-700w peak), light weight mid drive. I currently have a tsdz2 which I like very much, except the ground clearance. I do have a MY1018 brushed motor laying around here, a BB torque with a freewheel on the way, and a CA v3. Trying to make a lightwe...

Re: New "TSDZ2 Torque Sensor Central Motor"

I think there is a setting for the assist to have a delay of several degress rotation. A lot of times this gets turned to 0. That is what it's there for. To keep the motor off when resting your foot on the pedal. I haven't used the OSF yet myself, but I think that's the setting you need to change. ...
