If you require more then 15a output just look for one. https://www.aliexpress.com/item/36V-BMS-for-12-series-of-battery-assembly/1196501778.html? Ann battery a reputable outlet on Ali have used several times with no problems...

Buy the rim first then once you know the ERD use an online spoke calculator to measure the spoke length before ordering. Look for a double wall rim of 19 - 24 mm depending on the tyre size you are going to use. Cost of new rim about £20 on ebay. Once you know the spoke length use...

Freewheel has screw on thread, cassette has splines with one smaller one acting as the key way.

If it charges and works and seems to hold a charge then replace the bms plenty around just get one that fits. If charging proves fruitless then pulling that string and using a cell from other strings will reduce the ah of the battery and the amp load of the strings. You need to know which...

The specs for a lifepo4 BMS will have max 3.65v per cell charge voltage unlike 4.2v for li-on/li-po.

Could be a faff to fault find but if battery is fine and switched on I would start with disconnecting brake cut offs and throttle if fitted to see if PAS worked ,if good then reconnect throttle to try that and then brakes to start with. Whilst at it I would also check all above said wiring for...

They are knackered, kaput , fooked, no good :(. With such a low voltage not even worth trying to recover them. There is a method to recover unbalanced or low voltage cells at or above 2.8v or so but 0.5v is dead. Do you know what cells they are make/designation/mah ? You could try finding new...

God knows what stuff they use in them but they stink something rotten.

Cycling UK have a thread going on the A63 potential ban, the road apparently is a 60 mph road and with no where else for cycles to go. I believe a cyclist or two have been murdered whilst riding along with the fast traffic.

String no 6 reads 0.3v from that it appears to be toast.. Find the sense wire that gave you that reading and once you have removed the insulation etc, follow trace that wire to the defective string. A direct reading will tell you/us if the string is dead, whether their is a wire break down or...

Sometimes you can't miss the vapers they send out more smoke signals then the red Indians used to.

The 1000w ebay DD motors are no good for your needs. The motor windings are fast about 370/390 rpm minimum, they are designed for fast riding conditions also they are heavier at about 5.5 - 6kg. You need to be looking at a 201 rpm (code 13) bpm or even less form a geared motor as you want the...

Quite right K, that's why I didn't go further. We need to see the 10 voltage readings first.

Could be that the BMS is faulty and not outputting the req'd voltage or though it could be crappy cells as yours look like they are paper wrapped. On each side there I see two sets of sense wire jst connectors scrape the silicone gunk off them and disconnect them, using your meter probes you...

My converted Norco 700c is over 4 years old now approx 5000 miles still with original cassette and chain never cleaned, only oiled when it looks dry & doesn't skip or jump. Hub drives wear drive gear less.

The TP 10 385 is a speed controller with PAS.

For most people, families or someone wanting just a run around then the cheap options work. Buying from a large chain like Halfords gives them a presence in nearly every town or nearby out of town location. SW is one of the exception's on the forum he only looks at top rated expensive items...

Power supply issues are related to battery, controller or even a faulty led.. The led has a 5v supply so stays on so, until the battery is checked out a fault can't be ruled out though an intermittent wire short anywhere can cause the issue.

If the bike is still under warranty then it is back to the retailer for help or Electrifying Cycles offer might be the way forward , hopefully before too long you get the problem sorted out.

Unconventionally I put a bpm in a mtb 26" front wheel the bpm kit was excess to requirements so did it for a winter off road project. I have used it on the North/ South Downs and in between generally works quite well though wheel slip is there on very soft or loose inclines, I can overcome most...
