It's is the same case battery as the one I linked to from UPP also it is a yose battery which is on the the yose page. 20a continuous discharge with China branded cells it should be ok for the price, most likely it is also made by UPP with just with a customer brand name on the case.

Simply the BBS PAS is the same as a generic hub motor PAS, rotate the pedals and the bike will whoosh along with little effort. All is counts is each magnet as it passes the sensor so a cadence type rotation system, it is irrelevant to how much pressure one puts on the pedals. One can ghost...

Easiest way to get the chain length correct it to remove it from the derailleur and simply wrap it around the biggest chain ring and biggest rear sprocket the ends should meet with a max of two links over lap. Cut down your seat post if it is a generic non suspension one.

The mulitmeter may need a new battery. One can test it with any other dc or ac supply to see if the voltage reads accordingly. For instance a kettle plug or similar should show up 240v. If you use 18650 torch batteries, charge one and check the voltage. It would be very coincidental that two...

I can understand the logic of so called 'legal' by adhering to the max speed limit to gain the extra power for climbing as you say it is still a 1000w motor outputting some nominal 1300/1400w.

As said people see 1000w and then think it has to be 4 X better then 250w and simply don't understand the rating, likewise they also don't understand the current required and the battery specs to supply the current asked for.

The pics of the Tern weld failures showed up poor weld penetration/depth and for the most part seemed to rely on ugly surface weld.

There's an ejit around town here with one, mtb with it within the diamond.

I can only dream of a 120 cadence SW, typically 60 - 78 is my range and limit.

The sparks are normal esp as the controllers main capacitor would have been drained .

Half way there then, just needs a battery or another fiido battery rail to install on the furo if the bikes aren't going to be ridden in group ride.

To eke out range even more I now set the cut out to 20km/h which is a tad under 12.5 mph, no matter what I set the cut off to it doesn't stop me nearly reaching 20 mph unassisted nor make my speed illegal.

The existing furo battery base unit one should be able to remove/unbolt for safe keeping then likely one of the two frog/seat post options I posted may be able to fit and be secured to the seat post, then just a case of wiring up correctly the wire tails. The controller located at the base on...

No really it is down to purely how much you want to spend and the range you need. the controller is 15a max so all batteries will be at least 15a continuous ideally though the specs on the battery will need to be 20a continuous or more. Also if not sure link any battery so we can check out the...

Just one caveat, we assume being brand new it does work ? Can you temporary rig up the fiido battery if 36v to test all is well ?

Motor cable is std 9 pin julet but is now of little concern as one has a nice controller located in the seat tub box and a nice display to suit. All one has to decide is on the battery type to use, as I mentioned an easy solution to power up once battery is fitted.

That's easy then. All you need is any generic 36v battery, simply wire up the red & black battery wires to the red/black controller wires and you are good to go. You can get the bike working for sub £200 if you wish or spend more on a battery, all depends on how far you want to go. Controller...

Your battery hasn't gone to sleep but it has been left at a charge rate that is too low and has likely self discharged too low over the dormant months. Ideally it should have been left at a storage voltage of approx. 48 - 50v and checked once a month.

Two things say you have a problem. 1. 39.9v is to low to leave a battery for any time, it indicates cells sitting at < 3.1v or at least one cell group is lower then the rest and the battery cell balance is out. The BMS in both cases won't switch to allow charging. 2. The charge output is not...

The bar controller is a display unit, it can be led or lcd which is better. On has three options other then the furo option. First one needs to trace the motor cable to see that it uses a julet type w/p connection. 1. A frog type battery and remote controller. 36V 10Ah Seat Post Frog eBike...
