Re: Bike stand

You don't know my wife. She's wonderful & after 35 years marriage I still love her to bits but if she catches me touching her ironing board, she'll put the iron on my face instead of the board!

Re: What Strange Build do YOU have Bubbling inside?

I've got access to an old power wheel chair. Can't decide between replacing the footplate with a motor & blade to make a ride on mower or build a Dalek shell over it.

Are you sure the Meter is showing 23.5V and not 23.5mV? Spurious voltage.

Re: Bike stand

That's brilliant! Repurposing at it's best.
When my wife's not around, I'm gonna take a look at her ironing board, see if I can take the top off it, or even just turn it upside down.
Mate, you've got me thinking.

Re: Electric go-kart build from Jazzy 1100 mobility scooter

G'day Page. Once again, Amberwolf is quick & generous in sharing his knowledge. A couple of points though. If you're going to use the same battery & controller from the power chair, I don't think you'll have any heat issues. If you remove the brake from the end of the motor & disconnect them from th...

Re: Best battery option EVT 4000e

G'day people's. I'll share my experience with my lithium conversion. I have a EVT 168. Same electronics & mechanics as the 4000e. Swapped out the moped controller ( silver grey main lead, 50km/h top speed ) for the scooter controller ( black main lead, 60km/h top speed ) & changed the batts for 40Ah...

Re: Lithium battery upgrade for mobility scooter

You probably don't have to pull the motor. Just unscrew the 2 ( or 4 ) black plastic caps to reveal the brushes. With a brush out, you can shine a torch down the holder to check the commutator.

Re: Lithium battery upgrade for mobility scooter

G'day DB. I'd check the motor brushes. Unscrew the brush cap & take out the brush. Does it slide out easily? Could be stuck due to arcing. Are there black marks on the sides? If so, gently clean it with a Scotch Brite & clean black marks in the brass holder so the brush slides easily. Next check the...

Oh, now I get how it works. Thank you. I see another advantage would be that the trike stays upright when riding across or parked across a slope. Am I right? Clever & elegant engineering mate.

Re: Low tech Active lean E trike

Hi Hodala.
Nice idea. I have a question though. Wouldn't the pendulum be affected by cornering force? As I read it, centrifugal ( or is it centripedal ) force would push the pendulum outward, causing the trike to want to stand up just when you want it to lean. Keep at it though!

Re: Why does my 36v e- bike cut off when I put a 42v silver fish battery In place of the 36v silver fish battery

If you have a spare charge plug with lead from an old charger handy you could connect it to a multimeter, plug it in to the charge socket of the battery & go for a ride. You'll soon see if the battery volts sag. Sort of McGyver load test.
Let us know how yous go.

G'day Henry. If it helps you to get started, I have a NOS EVT 4000e you can have for $500. Never been on the road, never been registered, 2km on the odo. Missing swingarm & hubmotor.

Re: GM retreating into its shell ?

Yeah HH, you got me there.... Sort of. It's got the "Holden" name on it, but no "Holden" parts. Chassis is custom, sorta like a NASCAR stocker, engine is Chevy, drivetrain, ZF race, suspension is Bilstein ( I think ) & body panels are Opel.
No Holden in there mate.

Ford respectfullly retired the Falcon. GM rebadged an imported FWD that isn't even built by GM & hoped no one...

Re: Ebikes are they AC, DC or?

Ok. So there's AC buzzing around inside the coils of all motors, be they 3 phase AC, induction, pm brushed DC, BLDC or. universal AC/DC. I can accept that. 3 phase AC has 1 phase feeding each coil all the time at a constant frequency, 50 or 60 hz. A BLDC controller feeds pulsed DC to 1 coil until th...

Re: Ecoreco M5 forkplay

Hi Galcohen.
The play is most likely from wear on the folding lock pin or in the latch hook. If the head bearings are loose, you'll have to remove the front wheel & mudguard to get at the adjustment. Hope this helps.

Re: Ebikes are they AC, DC or?

The controller sends pulsed DC to the phase 1 coils, Then switches to phase 2, then phase 3. The confusion rises because there are 3 sets of "phase" coils but it's not 3 phase AC.

Re: on-off ignition switch

Fuses & connectors, over time, can grow a thin layer of oxide corrosion that's basically a resistor. The resistance restricts the current down to enough to trickle charger the caps in the controller to wake up for a moment but when they are discharge the controller shuts down again. A bit like a tor...

Re: on-off ignition switch

G'day AM. I don't think it's the switch, though I bow to Amberwolf's wisdom. I reckon it's in the battery feed circuit. Look for a bad fuse, loose, melted or corroded fuse holder or a melted / corroded connector. If the fuse is a glass tube type & seems to test ok, try replacing it. I've had them go...

Re: Lithium battery upgrade for mobility scooter

You could put a resistor in series with the gauge. With your batt discharged to what you reckon is the safe minimum, use a decade box in series to work out the resistance that makes the gauge read empty then wire in that value resistor.
