This is probably one of the best conversions I've seen. Very well done. Question/Suggestion, When you showed your battery wire routing, it looked like you had something else connected to the battery end of the shunt. For the shunt to work properly, tracking all incoming and outgoing amps, the battery should be the only thing connected to the battery end of the shunt. Everything else, including chassis grounding, should be on the Load end of the shunt.

@GaiusGarage

Hi, neat build, can see you put a LOT of thought into this, A few questions if I may? On the charger wires, You have them going into the cabling box, does this box have a weep hole on it? The reason I ask is because there are no drip loops for any condensation (water) that may run down them, (I did not see any weather proofing grommets on those wires where they entered the box). This could cause the box to trap condensation which could lead to corrosion on those contacts of the plugs inside that box. The only other thing is where the phase wires pass, very close to the shock spring which moves quite a bit, I understand wiring code say that wires need to compress rather than stretch all good with that, and I understand you would not want sharps bends or tight pinches in them, is there possibly another route for those? Other than that..... MAD MAD MAD respect to the attention in detail you have put into the build.... Very very very nice!

Really good job man...!

Nice job! I have a question relating the contacter. You run a DC-DC converter i suppose?. However how do switch on the contacter with 12v when the battery is disconnecter (aka contacter is open)? Or is your dc-dc converter positioned before the contacter? Thanks

@GaiusGarage

8 ай бұрын

This is a good question and Ive gone down the road with the handful of solutions. The solution I decided best fits this particular bike (and probably most smaller builds) is to run the high-voltage input through the key switch and to a solid-state relay that powers the dc-dc converter. because the voltage is high and running power of the relay very low (only about 5W) the current in the input line is extremely very low (less than 0.1 amp) so its ok for it run through the switch directly. this way, when you turn the key, it activates the solid state relay, which allows current to flow to the dc-dc converter and power the 12V electronics, one of which is the contactor. I have a video showing the power converter module used on this bike here: kzread.info/dash/bejne/anZ7m7yxcZzOqps.htmlsi=S5j4sZa6yZIZbZqH

Awesome build, could you explain why you chose mid-drive over hub drive? I understand that it can provide more torque and allows you to take advantage of gears, but penciling out my own build, it seems like hub drive is both cheaper and simpler. I think the big reason I want to go mid drive is because it’s cooler 😅 but I’d love more reasons to justify it. Thanks, your attention to detail is crazy and the build is super clean

@GaiusGarage

8 ай бұрын

Much appreciated! Its definitely a pro/con for hub vs mid-drive. Hub motors are simpler, quiet, maybe cheaper, and you have more room for the battery pack. The downside (especially for motorcycles) is a ton of weight unsprung in the rear wheel, having to deal with a really heavy wheel with giant wires coming out of it if/when you get a flat, then worst of all is accounting for with the huge forces on the dropouts. And as you mentioned, you cant really change the gearing and thus top speed other than by increasing voltage or using flux weakening.

In what way are hubs cheaper for you? I went down the rabbit hole and it was almost twice the price for my specs compared to mid

there are pros and cons to both - hub motors are quieter & allow for more space in frame but the massive unsprung weight at the far end of the bike makes for sluggish handling and poor performance off-road, changing the rear tires becomes a chore, protecting the phase wires is an issue, and reinforcing the dropouts for the massive torque is another challenge. personally I think hub motors are better for ebikes, mopeds, cafe racers, & cruisers, mid-drive is better for dirtbikes, sport bikes, and enduros
