Hey Justin What a fantastic trip! Sure an epic personal experience other than technical for you and Anne-Sophie. Sadly I was not in Italy when you experienced the fantastic "ai pioppi" restaurant-park, I know Bruno and his works and would have been perfect to meet you again and re-visit "ai...

Sounds Good! I would repeat it again and again, though: don't expect pedal ability from this config, at all. How do you plan to fit a 15mm jackshaft where the previous was 12mm with supposedly 12mm ID bearings?

I think I have not a 180° flats on my astro. But I maybe wrong, It works just so fine and reliably that I haven't removed my primary pulley from the motor shaft I think in the last 3 years or more :wink:

I'm pretty sure you can ask Astro to have whatever kind of flat degrees or coupling option if you order directly from them.

Ok understood about the motor mount. This could be a problem indeed. In theory You could ask Astroflight to make a motor with a protruding shaft the other side. Generally speaking if these BL motors have a side, that's only related to eventual differences in the shaft supports. However I would...

what you mean with mount on the opposite side on the motor? A BL motor has not a "side", it can be driven CW or ACW simply swapping 2 of the 3 phases....you just need to verify that the 4 bolt holes in the Astro will match the frame mounts. Standard 1.37x24 FW units are 14mm to 20mm wide. A...

There are some factors pro 18650 and some pro Lipo, when you think about a battery pack for ebikes: but almost none of the 18650 adavntages apply to the high powered bikes, while all the downside are more than a concern. I would resume the major downsides I experienced: 1: A 18650 pack under...

Interestring adapter. And if you make a batch of them and have surplus count me on one at least. Wonder what's the adapter ID and total depth. As about the material. 7075 would be probably more than enough. The only possible flag I see, just to be the devil's advocate, even with the snapring, is...

You will not get any reduction until #1 is bigger than #2 11:11= 1:1 you actually have 14 to 11 that is the opposite of a speed reduction. Do your search with your code and pictures, it shouldn't be that hard having the product in hands, Y. of production could be the key. Another way, at least...

You could ask me why I would use a different crank sprocket freewheel assembly , from the actual: because I doubt that the csk will withstand the torque from your pedal input under load (you have actually a 10:17 that means 0.58 ratio, a human is capable of huge torque although without much...

1 - you wrote 13 in the thread earlier.....so it is 14 instead? I've told you that was 14t from sellik pictures! :twisted: 2 - 11t : no you cannot use that. you should use a sprocket that is bigger than 1 to get a reduction (1.15 bigger in my hypothesis) but Looking at that picture: seems to...

the simplest way would be the followings, I will use the numbers of your sketch 1: keep the 13t you have especially if you can transplant everything to the new motor. 2: a 15 t sprocket at APEX input will give a 1.15:1 ratio, the gearbox should sustain 7000rpm and about 8Nm torque peaks inputs...

the only smaller disc hubs I know are some 130mm road and 116mm trial. The 116mm trials are all thread on hubs though, and build a big wheel with such a smaller OLD is not ideal. Do not put much efforts in the pedal test with the old jackshaft. I'l recomended it just to be sure the bike is ok...

If you keep the thread and bike alive I'll actively help to check and guide your steps for what I can. But you should understand that most of the efforts are your part. As suggested before I would start having the pedal bike fully functional and testing the pedal pivot transmission first, if you...
