These guys claim that they contacted pswpower (april 2019) and was told that the wobble in axle was normal, so I reckon I will still keep using the bike. https://endless-sphere.com/forums/viewtopic.php?f=28&t=79788&p=1458854#p1458854

Hi. I have some similar type looseness/wobble after a few hundred Km but its not so bad as to cause scuffing. The left side seems to be worst and I have seen it suggested (endless sphere) that another second bearing can be made to fit in here, although there is some concern about how to remove...

I am not specifically familiar with your set up but I was similarly unhappy with chain line on TSDZ2 with the lower gears. Anyhow I managed to dismantle the gear cluster and rearrange cogs to give a wide spread of ratios over 7 speeds with the chain line on the 18 tooth cog. i.e...

Hi. Those voltages look low. Normally (there my be exceptions) hall sensors are powered from the 5 Volts in the controller, sometimes fed via a diode , so I would expect something between 4.2 to 5 volts on the controller side. Try disconnecting the pas unit ( in case there is a short circuit in...

No problem. Ignore my key number on third page. PS. 2017 model, may be some differences.

I have attached a copy of EN15194. Its dated 2009 so I'm not sure if its up to date. Anyhow, if you read the document, you will see that the 250W refers to maximum continuous mechanical output power (measured at wheel) and not the electrical input power to motor. There is a complicated graph and...

One further test. Try removing battery from bike (you need the key) and then try to recharge. I am disappointed to hear that Halfords wont look after you. I am a bit slow to recommend you a replacement battery as they are quite expensive and there is no 100% guarantee that they work or indeed...

I think Halfords gave a two year guarantee with that bike and battery. How long have you the bike?

I am a little familiar with that bike. But some more detail. Normally, the charger plugs in and the red light comes up on charger to indicate battery is charging. After a period of time (about 4 to 5 hours max), the light turns green to indicate battery charged. The charger also gets a little...

I changed one like that lately. I got this photo online and seemed ok. I think yellow was the ground and blue the signal in my case but let us know if photo not ok.

Hi. I have fitted both the yose 350w kit that has no light function and a yose 250w front wheel kit that came with the extra wire in control cable and extra front connection that connects to supplied front light only. Both kits had almost identical KT 15A controllers and LCD3. The front light on...

Be careful. The light function controller uses a 9 wire 1T5 control cable so you may need to also purchase this to get the light to work.

Pulse Width Modulation (PWM) is used. Plenty of explanations on line e.g. https://en.wikipedia.org/wiki/Pulse-width_modulation

You have to be very careful You have to be very careful if doing this as the individual cells are not fused, and the wiring wearing or shorting could overheat a group of cells and cause fire. Its also a tedious job individually balancing the cell groups. (It is generally recommended not to...

Some batteries have to be turned on to balance. But I have a small (7ah) cheap battery that has a small BMS (no load resistors) that does not have a balance function and needs to be rebalanced manually every few months, which I do myself. I believe this (no balance function in BMS) is common...

How about a 69er i.e 26 inch on rear and 700 with larger tyre (29) on front. Then transfer speed sensor (if possible, but might involve piecing extra wire length) to front wheel so there will be no speed error.

Hi. I notice that on my Bafang rear hub, the motor continues to spin very lightly when coasting, even when not pedaling. I think ( correct me if I am wrong) the reason for this is to reduce wear of motor stoping/starting and it keep a little pressure on the roller clutch to stop it...

Just to clarify a little. For the sake of this discussion, we will say that there are two ways to go about fitting two hub motors to a bike. The first is the 'dual motor' way where 'dual' controllers are used so one throttle or pas can control the two motors simultaneously etc and one large...

If your front kit has a display/lcd unit/led unit you can leave it in and wired but you may have trouble fitting and cluttering the handlebars and may have to stuff it into a (handlebar bag) bag somewhere. The 'jumper plug' is a nicer and safer way than shown below and comes with some kits and...

I live beside some mountains with some quite and beautiful roads but with long grades of 5 to 10%. The single hub and my weight (90Kg) and weak legs are not enough for the steep bits and the bike just stalls on the hills. Anyhow, I had an older spare bike with a mxus front hub and battery, and...
