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...

I have 8000KM on Yose 350 rear (freewheel) hub. I have found the kit not to be great against strong winds and hills. (The controller I got with the 350W kit is only 7 amp continuous (15 max) rating and gets very hot under pressure.) Last summer, I got fed up of its lack of torque and stuck an...

Something I have been thinking about. It seems to me (am I right) that you initially set up your bike with the Yose LCD3 and Yose KT controller, and then sometime later swapped in a larger KT controller bought from a different source. OK There could be compatibility issues. However, I think...

I am using the Samsung 29E's at 4P as an auxilary (parallel) battery along with the bikes original battery ( 8.8ah which has over 20,000 km /600 cycles clocked up) and has lost about 25% of its capacity. The bike controller is 14 amps max, so I guess the batteries have an easy life now. I tend...

I made up an auxiliary battery lately with 40 of 29E but they were version 6 and had solder u tags and (I thought) were at a good price of 2.22 euro each. Anyhow, one thing I noticed on ES is that they are testing their cell life at 1C or less, and there seems to be a general recommendation on...

Sorry, I have no experience of cassette. But the principle is the same, i.e. there is a rachet and pawl that's part of the wheel. You can check its operation by unhooking and tying up the chain. I would check its operatiion and try to lubricate it first to see will it solve your problem, as I...

Is your hub a freehub with a cassette or a screw on freewheel hub? With the screw on freewheel, you get the oil into the gap between the movable part and the fixed body of freewheel, which is on the inside of the smallest gear. On the 8 speed, this is hard to see, as the smallest 13t gear...

I (and another poster) had a similar problem with a Bafang rear hub fitted with a DNP epoch 8 speed freewheel. The electric hub worked fine but the pawls were sticking in the freewheel, resulting in no resistance or drive from the pedals. The cure was to squirt some fine oil (I used 3 in 1) into...

I agree. What I have noticed about the 14g spokes (on my wheels) is that (because they are more flexible), they wrap themselves snugly around the hub flange leaving no air gap and no room for movement. When I look at my 13g spokes. there is nearly always an air gap at the hub flange, which I...

PS There are advantages to using the existing spokes, e.g. The have become pretensioned from use and will have (hopefully) curved nicely around hub eyelets. Hopefully the spokes wont be corroded and will open without damage to spoke or nipple. New spokes have to bed in and need to be...

A quick and economical way (using old spokes) to replace rim is the following. 1. Be sure that replacement rim is same inside rim diameter as old rim, then spokes will fit.(ERD and Rim height of cross section will also approx be the same). 2. Loosing all the spokes gradually. 3.Tape new rim to...

The small led located towards the top of the unit seems to have been the weak spot in my case as its legs were black with corrosion. The cable entry was facing downwards and looked dry.

I got caught out today with a rear hub Bafang PAS (with no throttle) about 7 miles from home. I had to pedal the whole way home. Anyhow, after some probing, the PAS sensor (kingmeter with led) was found to be faulty. I took it out and dismantled and removed its cracked sealent and you could see...

Ok, thats the kind of detail I was looking for. Now, from what you describe, its very like an lvc (low voltage) cutout from the controller although the battery indicator outline normally flashes to indicate this and it can be reset by pressing the center button momentarily without actually...

You have never really given a good description of what exactly happens or what exactly you mean by 'cutout'. The reason I say this is because there is a sort of 'pause' condition on some bikes that is just caused by a delay built into the controller. For example, on my Bafang hub, there is a...

Just to clarify.(what I think)..... BMS cutout This happens in the battery. It happened to me and was caused in my case by a broken balance wire. In this case, the power is interrupted to both the display unit and the controller and to any external or display lamps. The bike may only go dead...

With the LCD3, by hitting the center button twice, the battery voltage in real time is displayed instead of km/miles distance. It will stay on throughout your journey You can clearly see any battery sag as battery voltage falls. Also, when LVC cutout happens, the LCD3 remains on but battery...
