    Is the extra 5 amps chewing up my range?

    Mines the same, nothing significant unless going hard and bounces back pretty well unless it's a big climb

    Is the extra 5 amps chewing up my range?

    How much sag is too much?

    Is the extra 5 amps chewing up my range?

    13ah There's no individual ratings just pack spec, 25a continuous/40a pulse. They are generic cells

    Is the extra 5 amps chewing up my range?

    In today's experiment I lowered to 20a, the performance was crap and the battery usage wasn't really any better, again pretty windy. What I have noticed though is that at higher current the battery starts to really plummet once it gets below like 48v so I think the sag is really killing it off...

    Is the extra 5 amps chewing up my range?

    I'll experiment with the amps settings and see if that helps, was pretty sure more current would drain more was just surprised how much. Doesn't help that it's been windy so that might have contributed although I have been pedalling. 25a is the max continuous rating of my battery so maybe it's...

    Is the extra 5 amps chewing up my range?

    Recently I've moved from a 20 amp controller to 25 amp and I'm seeing a significant drop in range on full power, I'm ending with 2 volts less than normal on a 15 mile trip. Is this typical for this increase or am I pushing the battery too hard?

    Spare spokes

    A labeled spoke key will also tell you the guage, the smallest one that fits the spoke nipple. Easiest way to measure length is to take one out, twang it beforehand and tune it to the same note when you put it back. If you don't have a musical ear then just do it by feel. I've done plenty of...

    Throttle to controller connection issue

    I've never carried it but have thought about it after some disasters. I think some butt crimps or bullets and a small crimper and some side cutters would be a more convenient option for roadside, would also work in the wet if you're that unlucky. As for replacement tips haven't needed any but...

    Throttle to controller connection issue

    I have the gas soldering torch from Aldi, bargain for a tenner! It drinks butane but the stuff is only a pound and not being attached to a cord really helps in ebike repairs imho

    Throttle to controller connection issue

    Also those throttles are kind of easy to break so it's worth ordering a spare. I recommend the wuxing 130x type that can be had for a few quid on eBay, again it will probably come with the wrong connectors as there is no standard so you really need to figure out how to change them because I've...

    Throttle to controller connection issue

    Yes that looks like a throttle input to me. You have a few options here, you can buy a male connector for the throttle with the wires attached and solder it onto the throttle with some heat shrink over it, just make sure to match red to red wires and black to black (green and white are the same...

    Kt regen settings

    I believe it's true regen (at least to a degree) as it shows a charging animation on the display and the voltage does increase if you use it for long enough, there is very little actual braking force felt. I guess the only way to know is to cautiously test the stronger settings and monitor the...

    Front Mac motor or possibly bafang motor axle

    Maybe speak to a mechanic, maybe they can use tap and die to cut new threads, not sure if there's a limit of stripped where this is no longer possible but worth an ask. Also have you asked if the new style axle is compatible with the older model? It might be that you just have to change to a...

    Kt regen settings

    I'm tempted to try a stronger regen braking setting but the kt manual states that levels stronger then setting 1 can damage the motor. How true is this? Also it says something to the effect of stronger braking recovers less energy. Eh? Surely strong regen would recover more energy as long as you...

    Help! Dc/Dc converter

    You can get lights that run off battery voltage, eBay and AliExpress are full of them. If going directly from the battery lines a fuse is recommended, in my case my controller has a light output. Many of them have switches with a horn and some even indicators which is nice, if a little overkill...

    Direct drive hub, 15 amps controller enough?

    It seemed ok today, it struggled with a steep hill though, definitely needs more amps. Didn't get any cutoffs yet though. It just needs to survive until a suitable replacement arrives

    Direct drive hub, 15 amps controller enough?

    Hill torque is acceptable if not great, I've ridden 250w setups that have been worse. Will probably be ok on longer rides as we have mostly flat commutes, there are a few gruelling climbs we do but they are pretty short, just depends how much heat builds up in the controller during those. Tbh...

    Direct drive hub, 15 amps controller enough?

    Well just finished installing with the existing controller, it's surprisingly responsive at 15a, better than I was hoping for. Only a longer ride will tell if the controller will die, of course it's not ideal so will be upgrading soon

    Direct drive hub, 15 amps controller enough?

    Mines running a 9 fet 25a and it runs just fine, no excess heat or anything like that

    Direct drive hub, 15 amps controller enough?

    It's advertised at 22mph but we'll be running it at 48v so it'll be more. Pretty sure we're going to have to invest in a new controller then unless the included one is dual voltage. They are cheap enough so not a big deal, a bigger problem is it won't fit in the box but she has space under her...
