ES 1.0 Graveyard

C1=2 is setting on last kit I fitted by default and worked. (Previous kits had C1=7). Greenbikekit says C1=6 I think as quoted below for KT-V12L. I hope it helps. Note: This PAS only work with KT controller. Also,Kunteng controller normally set C1 = 2 as a defaullt setting for the 8 pole PAS, if you...

More pictures coming soon. hub.jpgspoke-fitment.jpg Just my opinion but the spokes look too long at the j bend and are probably too hard and strong to bend and wrap themselves nice and tight around the flange like lighter 14g spokes do when they bed in after prestressing. (I do this using leather g...

My own experience is that there is way too much dish/offset on some rear hub motors relative to the flange spacing. [...] I corrected the situation by changing from 8 speed to 6 speed freewheel and reducing the dish/offset by over 4mm, and fitting lighter 14g spokes on the non drive side. In that s...

Bicycle Wheel building has been around over a hundred years. Why companies don't do it right is about money. A well built wheel is not cheap. My own experience is that there is way too much dish/offset on some rear hub motors relative to the flange spacing. For example, my first rear hub had 42mm f...

So I'm looking for a good rim and custom lenght spokes from a reputable company in EU (because of shipping). I live in Ireland (EU) and no problem buying Ryde rims when they are in stock which is not always the case. I have bought rims and spokes from bike24 on a number of occasions but there are o...

.........If I fitted a torque sensing motor, like the tongsheng, will it detect and respond differently to the difference in power on the L/R pedal stroke? I'm concerned that this would give a stuttering output and a very strange ride. ...... That's exactly the case with my 36v TSDZ2. I end up usin...

Both correct ofcoarse, but for slightly/partly demagnitised motors there isn't some sort of reference you can check when making measurements :( I am going to suggest that there is a reference that only requires a clock or stopwatch (and a throttle/way to activate motor at full speed). When the magn...

"Are there any tests that will diagnose a 'demagnetised motor'?" Sadly enough it's not a black-and-white thing, so it can be a "bit demagnetised". For those cases there really is not test to say definitively. Would it not be the case that an unrestricted demagnetised motor would...

index.jpg Hi. My understanding is that its a mistake to treat wind resistance like friction, which is often linear. When a cyclist runs into air, he puts the air particles into motion, very much like a snooker ball striking another. There is a transfer of Kinetic energy from the cyclist to the part...
