Glad to see you used logic and found the correct sequence. You did presume correctly, sometimes China colour coding/sequence can be all over the place but as a general rule and as you have found 5v/+ can be Brown or Red, Gnd Black or Yellow, any other colour is used for signal.

Also if you are able to enter the old Elifebike.com for small hubs though my pc redirects me to the knew PSWPower domain.

Disc brakes a few options. 270 - 290 rpm is ideal Q100 36v 328rpm for speed looks like it will fit, hub is 108mm dia. Q75/85 not disc comp. GBK 328rpm https://www.greenbikekit.com/36v-100f-front-driving-e-bike-motors.html Or 285rpm ideal speed...

Depending on the cells & age the 0.5v may be recoverable, on ES a guy has recovered PF cells that were reading 0v. They charged up and stayed charged giving good use and full ah. BMS minimum charge cell voltage varies (2.8v is often the min), 0.5v will not allow BMS to switch on for charging...

BMS are too complicated to fault find. Readings can be taken via the sense wires or main supply/discharge wiring to determine if it is working as it should, otherwise nothing the normal layman can do with them. I would assume the new one you have wired correctly should work but will only do...

For warranty issues and software upgrades local has to be better then faffing with re-boxing/mail order, though local may maintain the bike but for a fee. The extra £180 for the Kalkhoff will be worth it in the long run. Both bikes are good branded ones and nothing wrong with the Kalkhoff, my...

The issue can be any where. You need to be methodical in testing /checking rather then guessing at this or that. Controllers usually work or not they often don't give a middle ground, though on BBS can give strange power surges when failing. Start with battery V output, if ok put in on bike and...

48v 13s should read 54.6v fully charged, 51.5v is too low. Check the voltage output of the charger should read 54.6v. A cell group or two may be out of balance and are of a higher or lower voltage then the remainder, if this the case the bms will not switch on to allow the charger to do it's...

It calculates via the hall sensor/magnet passing in the hub if it has internal sensor.

What s the bikes current top speed ? Not all controllers can be de-restricted, unless there is a linked cable to disconnect or potentiometer to adjust. Some allow access to extra speed via the lcd. Low brake means that the wire carries 5v when not active, once brake is activated it reads 0v...

:eek: Blimey, this is one combo I didn't expect to see for sale.

Ride you bike till battery hits lvc, then you find what wh per mile you afe capable of for the prevailing conditions.

Not good advice to charge any battery with a charger with a higher rated voltage output. In the case of 24v 7s then the charger should have a max output of 29.4v and as we all know 36v should have a max output of 42v. Over charging cells will destroy them in time and result in a possibility of a...

I have used a double chainring 32/48 on a Alfine 9 with 20T sprocket with front hub drive and so far the IGH is still in working order.

The TSDZ is not without issues on ES there is a large thread on the topic, with controller issues and the blue drive gear suffering problems.

Nearly as bad as a recent leaner driver prosecuted for his driving, trying to evade police at up to 85mph including driving on wrong side of the road etc,etc. Police gave up the chase for safety reasons. I think he was given a 4 months detention and a measly 2 year driving ban.

True but was more conspicuous probably due to his age and the high speed he was deemed to be travelling at. Also these are pedal less so propulsion will be known not be of rider input. Typically because of the size of these scooters they will also appear to be a lot quicker then a ridden...

Go easy on the solder use a thinner core solder, with the lid off and proper access try a bit of kitchen towel to prevent drips /splatter affecting other components or tracks. Add a bit try it/ride it & add more if needed to max of 25/30% of shunt, typically solder the rhs leg of the shunt on...

Not forgetting although the gear ratios are set % wise, you can change the theoretical gearing by changing the rear sprocket size though this is dependant on which T size chain wheel is used. A front chain ring to rear sprocket ratio should be 2:1 for warranty purposes but you can get away with...

KT lcd3 and controller will set you back about £80. You can buy the cheaper lcd1 or 2 but the 3 gives you more parameters to fiddle with and one of the important ones is controller amps, you can adjust them down ( approx. by 5 amps) to suit your needs so no worry if you get a 17 or 20a...
