BAK and lishen look like they will become more familiar names in the years to come with shortages on the main branded cells become even scarcer.

My first one was the Korea Boss arduino model about $80 it worked ok but got quite warm so added a fan to keep it cooler, then something went wrong and it stooped working. The guy in korea said it was likely the arduino so I bought a new one for about $15 and swapped it out, still refused to...

A bit late there is already a post/thread on it.

The 25r in 1p might be pushing things a bit even at 10a one will only get 1600mah down to 3.2v so range will be very short or if one can be sure of a max 5a draw then 2100mah. One might be better at 1p with the Moli p42a where one will get at nearly 3500mah at 10a or approx.3600mah at 5a. I...

In #10 the third link to the style of bottle type xgo use have been about for a good few years and empty ones are available on AliExp. The BAK cell looks like a worthwhile one to try and independent sources appear to back that up with it's performance, what isn't known is life cycle but at the...

For 10s2p they are fine for light weight bikes of if your mileage is only local less then 25 - 30 miles max, they only take and hour or two to top up. No use carting around a 8lb 15ah battery when a 3lb 5/6ah will d the same thing. As already mentioned one doesn't need more then 5/6ah for low...

The issue with flat mount is they are designed for road bike so lighter weight stuff, 140 is std with the option for 160 increase. Ideally for such a bike a smaller diameter hub motor like an akm 100 or 128 is better as the designation reflects the motor size, the larger bafang big boy motors...

With a 160 rotor, would a calliper still foul the hub casing ?

40mm calliper fixing is flat mount road bike territory and most use 140mm rotor, there are adapters for 160mm rotor increase. Type in flat mount adapters for any search for them. Shimano Adapter for Flat Mount Caliper to Road (sjscycles.co.uk) Bonin Flat Mount 180 mm Disc Brake Caliper Adapter...

Wrong place wrong time by a few seconds, a one in a million chance ?

One reason why I like the KT lcd3 and 4 is because the voltage readout is accurate and part of the main basic screen functions, voltage readout is worth 10x more then a simple battery status bar one can't rely on for accuracy.

Yes this is my thinking I have one with a bit of an iffy down button, it came from TBK nearly two years ago and only have just got around to fitting it. I have to be sure to press the pad right at the bottom of the down arrow but now I has set the perameters I won't need to use it much at all now.

The charge point is DC 5.5mm x 2.1mm socket which is a common type used. All of my batteries and I bought and now make all my own have used this simple generic type. This will work. 42V 2A Battery Charger For 36V Li-on Battery Electric Bike Ebike Scooters UK 6220570050319 | eBay

It has been along while since I last touched the build and it has been languishing in the dining room of the house. Finally fitted the double chain ring 32/42t set up and adjusted the derailleur changing, new chain fitted and links reduced. The battery box I have put on hold mainly because I...

Pretty sure with your persistence/perseverance one will triumph again.

My BPM clutch is quite accessible and no riveted plate to remove to gain access to the springs/pins. My 8fun cst has some 9k miles on it and a part from a bearing change have been faultless.

It is nice when the wildlife visit us and gives so much pleasure. My main daily/dusk visitor is Vulpes vulpes and has become a fixture over the years, in years gone by the cubs have played and visited. Last year the cubs were shy but there chirping during playtime could be heard down the garden...

Any one using one ? If so do the buttons works ok or do I just have an awkward one ? I like the minimalist look of it on the bars and it has all the features of it's big brother the LCD3, my only quibble with my one is the down button isn't too user friendly and one has to press it in a...

Having got this far with your trials and tribulations with this bike, this is likely the easiest fix for you.
