KT brand controllers are popular because you can select any LCD display from the range that meets your aesthetic KT-LCD3 is t most popular and probably the cheapest. google and check out the manual pdf files for the displays you are considering ;) (20+ pages) For a 250w motor, most bikes...

Good clear pic of the plate ;) did you get a swing with a d-lock in??

I doubt it will spontaneously combust, the energy in most of the cells probably dissipated in the expansion But if you start pumping fresh amps into it it could behave unexpectedly.. As for the number of connections, its probably a future-proofing of the battery format if for example 1...

Just in case Visible swelling through the hard plastic exterior case is a VERY RED FLAG ;) And since your asking here you have the good sense to check ;) so just to be 100% clear.. IMHO DO NOT ATTEMPT TO CHARGE THE BATTERY IT COULD END VERY BAD

.........Before the error first showed up. I must have cut the last bit of my post above..

That was my initial plan @saneagle until i started to google, and circuits with 1 or 2 resistors that would require an ebay/amazon order to be made before i could find some at the back of a drawer started showing up and the diode mode test 'seemed' like a extra component free option.. My...

I have tested the hub motor hall sensors (pictures attached) Using the diode setting of my meter each signal connection of the sensors all read 466-467 against common ground, sensors B and C read similar between + and -. sensor A Read 780 between +, and - 300 units higher than the others...

If exchanging a rear wheel is within your capacity and you have an afternoon to spare I would recommend considering a kit conversion onto a comfortable to ride bike with good brakes ;)

having converted my bike with a yose-power kit last summer and being as pleased with it today (very) as i was the first week i was in 'Weeeeeeee' mode.. They get a thumbs up from me.. the kit contained all the tools to exchange the back wheel and freewheel/cogs perhaps the length of leads i...

looks like someone has been in there with a flat blade screwdriver to 'adjust' the inner 2 terminals a little more than the outside 2?? though it could be a camera angle/light thing?? ebike volt meters are a thing and at about a fiver might be a better buy than a multimeter if battery testing...

posted in error..

Not as versitile as a multimeter but if battery voltage is the only reason for getting one one of these ebike volt meters might be a better buy?

Because the free and open exchange of ideas regardless of the niche is pretty important to many people, Only when informed can an informed decision be made on anything..

For most hub motors the sledgehammer approach taken by many is to replace the controller/display with a KT brand controller display combo. at a cost of circa £80-100 depending on source and display selection. A higher amp rated controller could supply more power to the motor if within your...

One good thing about ebikes, the extra mass of locks isnt the big deal it can be under pedal power alone ;) I would try 'working' the lock as it may be your item is at one end of the cumulative tolerances bell curve and just needs wearing in a bit?? repeated opening closing with it secured in a...

small locks limit access to jaw type tools used to break the locks.. its a design feature in some cases.

there is a youtube by Grinn ebikes detailing the cable replacement, it can be done..

Is keeping the original forks a must? Are replacement forks with a disk brake mount an option? If the current brakes are functional i would only look at the front for a hydraulic disk upgrade anyway, iirc from my m/cycling days your front brake provides 70%+ of the braking effort so is where...

Why build the battery yourself? is your bike/ev config special ? Do you have a particular range or weight target to hit? Or is it simply an area of personal interest and opportunity to learn and expand skills? We like project details in here ;)

Fwiw I can not cope with internal ear plugs i have yet to try one i can handle for longer than 10 seconds, consiquently i use an old pair of sony hook on the ear -phones.. corded unfortunately, but with the bonus that they do not drown out ambient noise at all ( volume level depending)
