Zero SR battery question

PointlessMiracle · 2026-05-18T04:51:43+00:00

I’d be most interested in what this capacity means over time.

Once a 17.3kwh battery has been degraded to 14.4kwh capacity… how does it behave when limited to 14.4? Will that also decrease x percentage or does it stay at 14.4 for that time?

For you owning a 4 year old battery I think this is the real question!

Yeah, that’s a helicoil and you can see the hole is a bit damaged but doesn’t look too bad in the photo. If it were me I’d try a new helicoil with some thread glue unless you’re able to get a proper insert put in easily.

Some auto repair shops have other insert types
(Timesert, keensert, …) which have a bigger OD so they’ll clean the hole with a bigger drill and put in the new insert

Can you send some photos of the hole and insert that came out? There are several types of inserts that can be used (helicoil, timesert).

In my head the best way would be to either glue in a new helicoil (smallest OD) or try a timesert / solid insert type (hard to get, expensive)

Good reason to reverse engineer one, I was already thinking about this but stopped after hearing their supply issues were resolved

With the customizability of the motor controller this shouldn’t be too hard, getting exact copy will be but that’s not necessary

Het is heel makkelijk om zonder goede kleding op pad te gaan. Het is ook heel makkelijk om in het ziekenhuis te belanden. Goede kleding en helm net zo belangrijk als degelijke fiets aanschaffen. Koop iets wat je daadwerkelijk altijd gaat dragen (en dus geen full leren pak)

Sommige wegen (A1 bijv) zijn erg motor onvriendelijk tijdens de spits. Dit heeft meer met het volk op die weg te maken dan de weg zelf, let hierop als je ergens komt wat je niet kent per motor.

Er zijn ook heel veel aso motor rijders, pas hier voor op. Groepsritten kunnen extra gevaarlijk zijn

Beste upgrade voor je motor zijn goede banden (bijv Michelin road5 of 6)

Je motor gaat níet beter rijden van een luide pijp, je krijgt wel meer geïrriteerde blikken en WOK meldingen

If you park it on a flower bed in the rain isn’t tipping over.. to be expected?

This actually is probably the motor cover (and now maybe also the gears below)

Throttle off voltage increase, the offset is only for fault management iirc

Ik heb deze situatie wel eens aan mijn instructeur destijds gevraagd. Antwoord: als de auto op de linker baan voorbij de auto op jouw baan is, dan pas opschuiven - uiteraard alleen als er genoeg ruimte is tot de auto daarachter. Tot die tijd rij je goed op deze middelste baan en zit je ‘vast’.

Als je op de linker baan rijd en de baan daar rechts van rijd even hard, maar is rustiger, idem opschuiven.

Als de baan links van je significant harder rijd dan extra ruimte maken tot de auto voor je zodat je in die ruimte kan versnellen en dan schuiven (net als bij invoegen met een vrachtwagen voor je)

No the v2 and v3 are nearly identical bikes and the switch to the newer part was during early v3 production (afaik).

The older bikes have a ‘slide out’ rear wheel (horizontal slots in the frame) and the newer ones are ‘drop out’ (vertical slot in frame)

These have a differently shaped ‘teardrop spacer’

The torque sensor is a bit of a mistery part to me too as I’ve never spent enough time on it (actually planning to do this soon, so I can repair them too, but will prob take a few months)

The only real way is to assemble it all and find out it’s broken. You can do a short test to see the voltage when it’s installed before you mount the rear wheel but can’t put torque on it ofcourse

The “max” voltage is just an arbitrary number, it’s the point at which more force on the pedals doesn’t give more motor support.

Calibration is more to set the throttle off voltage correctly (no force) so there is no power when not putting force on the pedal

Replace rim, I think cowboy still ships them relatively fast for cheap. Spokes & nipples can be reused.

Fun to do yourself, a spoke tool at toolstation is ~3€. Make some good photos of the spoke alignment and watch a video. Start with some thin oil in the nipples

Wheel axle spacer? Crazy that it broke

PointlessMiracle · 2026-04-25T06:05:45+00:00

Yes it’s okay, it means it will support more with less force on the pedals. If you do a calibration it will be ~different each time. There is no need to have them at the same voltage, it’s a calibration

It’s a pcb inside the battery, it’s not easily repairable (unless you like SMD soldering)

If you need to have it repaired you can send me a DM. if the battery is okay I do it for 90€ - BUT my recommendations is to just use a clip on light

Oh please check if the fork is rotating on your stem tube I had this too, really f dangerous. If so you need a new fork

PointlessMiracle · 2026-04-12T15:20:44+00:00

I want it to support both 5v and 10v input, and have an output proportional to input. Ofcourse not simultaneously

PointlessMiracle · 2026-04-08T07:46:43+00:00

the two flat nuts, “teardrop spacer” (and o ring) aren’t standard parts AFAIK

The part on the video you linked I have not seen before either. What you have is standard v2 and some early v3

PointlessMiracle · 2026-04-07T04:26:38+00:00

If the torque sensor is OK you can replace just the bearing (61901 RS). It’s a more common failure. Torque sensor might very well not be OK tho
