    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...

    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?

    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...

    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...

    Shaft adapter, splined and threaded for freewheel and cog

    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...

    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...

    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...

    hydraulic brake motor cut sensors

    Hey Justin! 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 tripwire eventually just needs a very minimal tune or ,the worst case, one needs to pull out the tripwire end from the wheel's slot, that costs 10 seconds.....

    hydraulic brake motor cut sensors

    True. Mostly for OEMs and assemblers, However, as final customer or DIYer, looking at the price...I'd probably still prefer a single or even a double tripwire..... or opt for a custom cheap solution if costs are a true concern.

    hydraulic brake motor cut sensors

    Hello there. I have made the e-brake lever with the sensor and magnets off standard ebrake donor levers too. it works well but is not so clean. However yesterday I have mounted the first tripwire in a Shimano XT lever and I've found a super straightforward method to attach it. Since I do not...

    Luna Cargo Frame with TDCM igh

    Eh...Kids are for picture purposes only ^_^, I carry my Joys in a much more stable way ;) However the Luna frame should take that load without problems. About the bike, the customer is pleased with the actual performances, I'll take the bike again today for minor services and to mount the...

    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...

    Hey kurster, your is a very nice build indeed. What kind of controller are you using? if you use regen, what kind of batteries/bms? For now the bike reamains single motored, but in the future who knows,....the customer has spent some money for the front end and White Ind. hub, and sapim strong...

    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...

    Luna Cargo Frame with TDCM igh

    I understand that point but She's good as is for the owner. He wanted the bike light as possible and clean. I could say it is surprisingly light and quick for the size, I agree that this frame naturally calls for a 2wd setup, though. Unfortunately there's the problem, here, that you can drive...

    Plans for a small bus conversion

    thanks Amber for your reply. The good is that the regulation is pretty precise and covers almost everything in terms of power and peed range (80-100%) total mass (115%) and front rear mass distribution (-+ 10% compared to the original) plus all safety and comfort devices and subsystems have to...
