No heat treatment planned. Material is pretty thick or in not highly stressed region...

@ DanGT86:
  • Distance from bottom bracket to top of seat tube was shortened by 4 mm when I cut the frame.
  • 6 setups
  • Maybe in the future ... :wink:

E-kross astro 3215 build

I finally got to make my next bike. I was planning on making a bike from scratch, complete frame and swingarm, but decided against (work, kids, ...). The donor bike is a kross moon, size L: kross-moon_640x358.jpg The motor I will use is a astroflight 3215. It will be a left side drive, single speed,...

Re: VESC 6, astroflight 3215, loosing sync with freewheel

Hello,

just to let you know that the problem seems to be solved. However, I did only test for a short time, and also limited the power. Tomorrow I will do some more testing and certainly in the weekend.

thanks

Re: VESC 6, astroflight 3215, loosing sync with freewheel

I belive the problem occurs when re-applying throttle, not when closing the throttle.
Anyway, I will try your suggestion and post the result.

Thank you

I'm now working on a more powerfull bike. Aiming for 120Nm at the rear wheel. I believe I will use a freewheel on the jackshaft.That freewheel be probably homemade as well. as for the rear wheel freewheel, maybe for a next project, if I can find a motor that can deliver enough torque so I can use on...

I'm also very interested in the gearbox. Could you show some more details of the internals? Is it something I could duplicate (I also have a cnc).

I assume it is the other way around? Nm/watt loss?
otherwise the BHT would be the better one, no?

Re: Left side freewheel sprocket adaptor

Hello, did a new test run yesterday. I'm running only 44Nm through it for now (put too much effort in it to destroy it the first couple runs :-) ). I also added a torque ramp of 1 sec in the controller. So from 0 to full torque takes 1 second. Engagement is smooth now. It is a real pleasure to ride ...

Re: Left side freewheel sprocket adaptor

First test run today. It was very muddy. Freewheel worked great. Opened her up after washing, I need to work out the sealing better for these extreme conditions. It was still working perfectly at the end of the ride, but the high pressure washer wasn't the best idea. a bit of cleaning and regrease: ...

The phaserunner has this option as well. Although I don't really understand what it means. The parameter is called "limit speed ramp time". I have it set to 30 000 msec, approximately the max value, but it still is not very slow. Does it need another parameter to work well? Anyway, tomorro...

Re: Left side freewheel sprocket adaptor

First test today. Just a quick ride up and down the street. It freewheels very nicely. One thing I noticed is that the engagement is harsh from time to time (as panurge already indicated). This might be a problem for durability, and for sure does not feel nice. Does somebody now if the Phaserunner h...

Re: Left side freewheel sprocket adaptor

First test today. It was running great with the wheel in the air. I started loading the wheel with the rear brake. When I almost reached full throttle the printed housing just broke open. I assume it very shortly survived something like 30-40 Nm. Oh well, at least I had 2 minutes or so of fun. On th...
