When the wheel has twitched does the power display frame flash (p12 of the manual)? Both the battery and the halls seemed to be flaky connection issues, not ideal for your 3 wires x 36 permutations tests. If both brake levers act one way in one controller connector and another way in the other...

Just checking... Wouldn't walk assist help to get it working regardless of PAS and throttle settings or connections, even with PAS level 0? Or does it already respond to walk assist? I assume brake sensors are never NC are they?

For now check the +/- power bullets on the controller resist a good wiggle (and re-test bike), re-visit if sequencing the phases doesn't help. Whatever size matches your battery should be OK and fitting new ones is easier than testing. That's because a poor contact can make the voltage dip at...

Probably harmless but when the motor's fixed this should really be fixed too, because battery.

You wrote "pressed walk assist...little man appeared on the display and then a slight noise from the motor as if it's trying then error code 03 appeared". Walk assist is nice as no sensor plugs are involved. It does sound like hall sequence, but if it isn't here are some pre-canal rites to...

If the above doesn't nail it, a very long shot but voltage dip on load can give confusing symptoms. Was the battery weirdness explained, is the battery ancient? Does the bike still have all its grunt with the old controller? Is there any kind of enable connection on the new controller other...

It would be less efficient and draw more current at normal pedal speed if it were driven at the new voltage, but then being a more powerful 48V system it would accelerate. To do the same work (climb at the same steady speed) as with the 36V battery you'd ease off until the motor operates at the...

Ditching the usual assist levels has transformed my bike but for the rest.... Can you talk about functionality and benefits?

"If I could sort out the sensors' inferface, anyone can write their own code using arduino tutorials or micropython to drive the PAS and throttle signals. There is no need to change the OEM firmware." Isn't this the low hanging fruit? The forum's full of ideas we'd like to try out if only...

So long as memory itself doesn't disappear with it you're OK :) Less battery current it's true. With the motor doing the same climb and speed as before, it's getting the same phase current as before and just as hot, with the controller converting as needed according to the battery voltage...

The throttle will expect 1.5 to 4.2V (and provide a 5V supply) and Micropython would certainly make life easy but I don't think there's a 5V MP board right now. I'd go with a XIAO and maybe pick the RP2040 version until MP on the SAMD21 is mature. A 5V PWM output using a FET would work for...

It's the same with my SMGT... I had Benjahmin's SMGT in mind when suggesting he try the fingertip test:

The T~ logo is for Terracycle, an Aladdin's cave for trike fittings. You can probably slide the grip down without cutting it, but unlike a trike the SMGT has banana shaped grips that you rest on lightly. Hence the cable being on the front side, and then having the mirror's bar end below the...

Can we take a look at your side, is there a cutout for the cable like this? Oh and Congratulations!

@saneagle: thanks for clarifying, with this many variables your experience with AKM is indeed what matters. @Benjahmin: would this PAS mounting work for you? (Not my bike)

Agreed regarding making heat, the biggest savings come from electrical design. Also these motors shed heat poorly (cool cases) so it builds up inside and a heavier motor heats up more slowly. Check out the simulation: the Ezee produces 0.7 times the heat, is 1.6 times heavier and takes 2.8...

The usual bar end shifter would be indexed for 9 speeds and switched to non-indexed when your old motor was fitted. With 9sp you could get at least 34T and maybe smoother shifts. The AKM128, BPM, Shengyi SY22 and your Ezee are all in the same power bracket but the AKM is 3/4 the weight so it...

Thanks flecc, it felt like a stretch hence "The wording here...". So, how do we know when we've reached the bottom of the well? You commented here [1] on not trying to understand the law from government guidance pages, and identified the separate parts of the law. How can we tell that the...

Fair point, here's my take and I hope to hear whether it covers me. From the regs [1]: "the vehicle shall ... [have working pedals and] ... an electric motor which (i) has a maximum continuous rated power which does not exceed 250 watts; (ii) cannot propel the vehicle when it is travelling at...

Actually with such a short commute perhaps reliability needn't dictate everything. I'm interested to see how it works out.
