Back in the office after a few hours, and the battery indicator is now at 4/5 (earlier I said 1/8th, but I have since actually looked at the scooter to see the battery is divided into 5)

 

I am sitting at 115kg, which is why I looked at a scooter that had a weight limit higher than that (I was looking at the Ninebot ES4 before I saw its max payload of 100kg). I have come to understand that max range on a scooter is advertised much like petrol usage in a car - under very strict conditions that don't really echo real world at all) but I would have thought I would get 20km out of a scooter charge.

 

I haven't yet moved off speed 2 - I am thinking mode 3 might be a little dangerous given the nature of most roads and footpaths in the area.

 

Maybe I need to send Freed an email..

A few things I'd note about the battery on the Zero scooters (based on my own experience):

 

  • battery 'life' will show as reduced when under load - by this I mean as soon as you've got your finger on the accelerator (especially full) you'll most likely lose one of the five bars; this temporary blip will return when you stop - if not immediately, a few minutes or so later.  I don't recall this with my old Mi
  • cold weather appears to have a direct impact on both the reported battery life (in terms of bars) and on acceleration; this difference is really obvious in my journeys to vs from work (cold vs warm weather)
  • I imagine cold also has an impact on maximum distance on a single charge, much like it does in an EV
  • a low battery has an even more significant impact on acceleration and top speed; this morning, combining a cold morning and a low battery made me think I was riding my old Xiaomi scooter it was so bad! Even in the third speed I couldn't go faster than 36kmh (usually will make it to about 44)

And, yeah, I am currently getting nothing like the claimed distance off a full charge; generally, this isn't an issue as I just need to remember to charge it about every three days - it's more annoying when it dies more quickly than anticipated so I have to ride a neutered scooter for the return journey (or, like this morning, return home after I realised how badly it was riding to pick up the charger!). I imagine this will improve as the weather improves, and I'll be able to go back getting more mileage off a single charge (if not, it would suggest a reduction in battery capacity, which would have me worried).

I have purchased a Zero 9. The charger runs quite hot.

 

A couple of questions to others with a Zero 9. Not a lot information in manual.

 

Do your chargers run hot?

 

I also assume the red light on charger will go green when fully charged? 

 

How long to charge if battery is at say 25% ?

Chargers for Zero 8, 9, 10, Xiaomi M365 and two electric bikes we have all run warm.

 

I think the Zero 9 takes about 5 hours from flat to full charge.

 

Yes the red light does turn green when fully charged.

Thanks for the information; I have a lot to learn it turns out.

 

On Saturday morning I was awake far too early for my weekend schedule, so took the scooter out on whatever charge it had from my previous days car-work-car trip. I managed approx 7km of around "town" scooting between 8-10am before my max speed when from 29km to 15km to 7km with E06 and E00 appearing, along with a noticeable shudder/clunk/no power from the battery. Thankfully I was pretty close to home so the walk wasn't too bad. However I am disappointed that a full battery charge only lasted 15km.

 

Fingers crossed when I manage to take the scooter out later in the day/in the warmer weather I will see better battery life/range, though until then I better neuter my expectations of just how far I can travel with the scooter from the car/home just in case. (I guess I could also use it as a manual kick scooter when it doesn't have any battery as there are no locks in place like on a Lime)

 

Took 8 hours to fully charge the scooter (give or take 30 minutes)

As I said in my post of 19/09, I believe that there is something radically wrong with either your battery or your charger.

 

My Wife (57kg) has a Zero 9, myself (95kg) has a Zero 10 and we regularly do trips of 25km - 30km with plenty of reserve to spare, have done a 35km one and were getting low then.

 

Mind you I note in a previous post that you are 115kg so you're really pushing a 9's battery and motor - as noted I am 95kg so I didn't consider getting a 9, whilst great for my wife up hills it is too underpowered for my weight, the reason that I got the 10 with the larger motor and much bigger battery.

 

So I imagine that you can expect less km pushing a 9 with 115kg (the smaller motor has to work that much harder) but it still shouldn't drop down to anything like the figures that you seem to be geting.

 

I understand that the range that they talk about is for a 60kg person on the flat with constant speed of 20km or something like that, but hills really kill the life - a 500m reasonable hill will take as much energy as probably 5km - 10km on the flat (think how much energy it takes to get a push-bike up a hill compared to the flat and you will see the way the motor has to work uphill) - but then the 25-30km rides we go on have a few hills as well.

 

So certainly worthwhile talking to Freed about it and seeing if you have a faulty charger or battery

I have replaced a battery on a Zero 10 which intermittently stopped with the E06 error.

 

Seems to be OK now.

Also a bit more info I've been able to ferret out for those interested - error codes:

 

Fault Codes:
E02 – Brake 
E04 – 6kmh cruise (don't know what this means!)
E06 - battery under voltage 
E07 - motor faulty 
E09 - controller faulty
E10 - faulty comms between controller and LCD
E11 – faulty comms between controller and LCD
E12 – BMS failure
E13 – headlight failure

I do have another charger; so after I get the current charge down to 1/5 bars, I'll swap over and see what the outcome is (which probably won't be until after I get back from overseas on the 9th)

 

I haven't yet even attempted hills on the scooter and I don't think I even will - I live on the flat and my general use will continue to be around the flat.

So I got a reply back from Freed rep, who has confirmed the Zero 10 handlebars have an internal diameter of 16mm, so these Cycl Winglights will fit; I've ordered the removable magnetic model, and hope they'll arrive around the same time as the scooter - will report back then as to how well they work out. (Edit: I assume they'll also fit the 9, but the 10X already has those things on the ends of the handlebars.)

 

 

@jonathan18
Did you fit the Winglights? 
Are they visible in daylight? 
Do you think other motorists can see them and understand they are indicators?

Topic bump reminds me

 

Order scooter, use scooter a few times, then head overseas.
Come back, weather is bad
Finally good weather - flat rear tyre after a month of not being used
Sigh

 

Who has recommendations for a good pump - is a standard bike pump that I can get for $10-15 good enough or should I be investing something a bit better

 

EDIT: I can't spell today

You don't need a fancy pump, just one which fits the valve ok. (I have a great pump for my bikes but the connector is too big to fit small wheels)

I've got a similar tale, but mine is more one of laziness and incompetence.

 

Got a flat on the rear tyre on My Zero 10a few weeks back; for the life of me I've been unable to get the tyre off the rim. The amount of force it looks like I need to apply is so great I'm bending my tyre levers. So different to a bike wheel, where the size of the wheel's circumference makes it much easier to remove.

 

Three weeks later I still have a scooter with a flat tyre.

 

Has anyone got any tips on how to get the @#$@# tyre off so I can repair the hole? I saw in a video from Falcon PV they sprayed the tyre with something before levering it off, but don't have a clue what it was. I'd appreciate any ideas before I give up and take it to a bike shop to get them to do it.

I have only changed one tube (Zero 9). Apparently the smaller the tyre size the more difficult it is.

 

The magic fluid I used was diluted dish-washing liquid. I have since bought steel tyre levers from Ali Express and suspect they will make it even easier next time.

 

I also found another tip on the Interweb - you can buy a plastic sewer pipe joiner which makes a good support for the wheel (rather than the axle).

@djtOtago: yep, sure did fit them. LEDs are certainly visible in daylight (and very bright at night). It took a little bit of practice to get used to turning them on and off while on the move (especially on a roundabout, as they need to be off at the time of exiting), but I've got it down pretty much pat.

 

I think they're more effective from the front (eg at an intersection so others know you're turning) than behind, but I sway somewhat to the side when indicating moving lanes (eg, into a turning lane) so cars behind me have a clearer view of the indicator. No accidents thus far!

 

I've come across similar but cheap-as lights on AliExpress, but have no idea of their quality or brightness, so if I was doing it again I'd go with the same ones (great price on TM when I bought them; not sure if still on there?). That said, on another site I saw some BT ones that used a mounted remote control. I can't imagine indicators on the back of the scooter would be much use, as they'd need to be mounted on a relatively wide bar (otherwise it would be impossible to see which direction they're flashing unless really close).
