What watts is it? Yes it's a 250Watt motor, thanks for the explanation Daniel:).

What you are describing is exactly what i have on my ebike. It is home built addition to the controller. It takes a reading from the battery pack and i set the threshold for the circuit to overide the throttle. This is how i get less than 10Whr/mile and can climb any hill without thrashing the...

Brand new Bafang 8fun QSWXK front hub motor for 26" wheel with controller and throttle. Tested and working. Controller is rated at 15A and has on/off road switchable mode.£150. mob 07792764633 or PM or email mkc1932 at yahoo co uk

I've got around 2000 miles on one of my tongxin hubs, but it developed a horrible noise suddenly. I've rebuilt it with some spare parts, hopefully it'll do another thousand miles or more, before something else goes wrong. I have another tongxin thats over 1000miles. I'm expecting that one to...

Sounds like it's twisted itself into destruction mode, I suspect the spindle is made out of crap material also. Can you post any photo's. Usually most things can be fixed. Without seeing it it's hard to judge what might be required. It might be possible to get someone with a lathe to 'turn' a...

Rather than using led's i would recommend a power analyser meter like a Turnigy. Voltage isn't going to give you a real idea as to the capacity used or what is left in the pack, you really need to know the Watt/Hours used. I bought mine for about £26 and use it when i'm on a long jaunt...

I would strip it down and investigate. Mine was intermittant (and annoying). The bearing housing was not located in position on one end therefore moving up and down with downward pressure, the other end being fixed and part of the assembly. I can't advise you as to which one is better, except...

I had to change mine recently. Only when i took it apart did i realise and could see what the problem was. Bad design, the sealed bearing race wasn't seating properly on one of the end adjusters, everything was ok when it was tight. I replaced mine with a shimano eqivilent and that fixed it...

We've all had 'Homer' moments. Remembering the lock but forgetting the key is my favourite. Doh! Doh! Doh!

Nice bike. What rpm do you get running it on 48Volt? i guess you have a BMS with those cells?

Well good luck. I've been following your battery problem with interest, I couldn't offer any advice, it seemed to me like it was totally fubarred. Hopefully you have found the problem. I did notice that you mentioned peak current hit 50A. Is this good for the battery do you think?

Thanks for informing everyone about the competion Vikki.:rolleyes::)

They are nice looking bikes. I'm not in the market for one however, but i have a question. Looking at the specs i see 'intelligent controller with Controlled Power Flow'. What is 'controlled power flow', how does it work?

Think of electricity like water flowing down a pipe:eek:. The gradient of the pipe would be voltage(V, volts), flow of water would be current(A, ampere's), any restriction in the pipe would be resistance(R, ohms)including the pipe itself. Very simplistic i know, but it helped my daughter...

Headwinds. They have a similar climate to us. Flat terrain can also mean no obstructions. The wind is so strong it feels like you are going backwards on occasions. Also their lifestyle incorporates cycling far more than us, ebikes just make cycling easier for those who already cycle. I have...

Thats a load of info for a bike ride. I'm impressed. Don't see many hills there though:). I also like to see how many miles and elevation i encountered on my rides. I use a version of memory map and plot the journey on the pc after i get home. I might have to get one of those garmin thingy's.

Tongxins are waterproof as long as you seal the cable end with silicone. It happened to me one January two years ago. Just got the electrics wired up and was desperate to try it out. I went for a 20mile circuit around my home town which takes me along some low lying ground. I should have...

The answer i had from Ping about how far to discharge the pack was between 80-90%. That is the tricky bit, knowing how far to keep using it before charging up again. On a regular journey you will soon find out. I use a turnigy meter to measure the charge in and out of my pack. Not sure how...

Interesting, thanks for that Frank. I only have experiance with Tongxin hub/controllers. There is no difference to max speed between SLA and a fully charged 36v Ping battery. I hooked up a scope to the phase wires on the tongxin controller and can see the PWM waveform. When it's full signal it...

Rob, a couple of questions. Do you know what rpm motor you have? The link to his site says they are 195. Can't see how you get 16.7 mph unless you have a 235 rpm motor, which is what i am hoping they are. 16.7mph is approx 217rpm. I've ordered a Bafang front motor and controller (but not from...
