Re: My Sun Trip Bike, Back to Back Tandem Trike with Rowing Generator, Pedals, +Solar

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 pioppi" ...

Re: Commencal Supreme Custom Mid-Drive Build

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?

Re: Commencal Supreme Custom Mid-Drive Build

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:

Re: Commencal Supreme Custom Mid-Drive Build

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

Re: Commencal Supreme Custom Mid-Drive Build

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 not b...

Re: Commencal Supreme Custom Mid-Drive Build

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 3prong c...

Re: voltage sag rc lipo vs Li-ion with heavy load

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 daily/u...

Re: Shaft adapter, splined and threaded for freewheel and co

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 a p...

Yeah... not much room at all... a belt would be nice but there's hardly any room in there for anything. Doesn't look like there are any active members on here that can chip in about the belt :( What if I make 1 smaller to get the necessary reduction? You will not get any reduction until #1 is bigge...

Re: Commencal Supreme Custom Mid-Drive Build

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 speed, a...

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: commencal primar...

Re: Commencal Supreme Custom Mid-Drive Build

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 with ...

Re: Commencal Supreme Custom Mid-Drive Build

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. It ha...

Hey Justin! and the trick of securing it to the adjustment wheel is great (assuming of course that you don't need to turn and adjust the knob too often after it's installed!) Eheh, yeah, But in fact there's no need to adjust the wheel so often and since the turn radius is so small, even then, the tr...

Re: is this a good choice

Yes the bike is a very good one. It is good in general as a bike, and I think is good also for a BBS, because they have typically straight or almost straight downtubes. 73mm BB shell will fit a BBS with no particular problems. All the modern threaded BB shell have British ISO 1.37x24tpi with RH and ...

Hello Steven, You need a new shaft made by steel or Ti. It should have a key groove both ends and/or flats for screwsets, if you want to keep the beariing assembly, than you need a 12mm shaft as it was. At each end you will mount (with keyway/setscrews) the staton inc freewheel adapters for standard...
