    Brake cable Vs gear cable

    There are several differences I believe. Gear shift inner cables are usually either 1.1mm or 1.2mm thickness. The nipple at the end will also be different for Rapidfire / STI / twist grip shifters Brake inner cables are normally 1.5mm or 1.6mm. MTB / STI nipple ends will be different.

    Tongshen TSDZ2B and a Thorn Explorer Tandem

    Like you, I wasn't sure if riding solo would trigger the torque sensor at all, but it seems to work perfectly well. I checked the nominal value of the torque sensor on the 'new' motor and it is right in the ball park at 72. I think the torque sensor simply measures the amount of 'twist' on the...

    Tongshen TSDZ2B and a Thorn Explorer Tandem

    It seems to be an accepted norm that one can never have too many bicycles (n+1). That said, I haven’t seen a similar argument presented when it comes to tandems! We have an Orbit Velocity tandem which was converted to e-assist several years ago with the installation of a Woosh 48 Volt DWG22C...

    rear view mirror

    I don't understand why so many cyclists ride without a mirror. I started using them many years ago and I just haven't looked back ..... (I'll get my coat).

    Are the KT controllers slightly pessimistic as far as battery level ?

    I have a very limited understanding of the electronic side of e-bikes, but the KT LVC settings have seemed a bit too low to me. I suspect that Nealh is correct in that the battery BMS will intervene before the KT LVC level is reached. I originally had a Lishui controller on the bike and I...

    Are the KT controllers slightly pessimistic as far as battery level ?

    I'm a relative newcomer to the KT system, so still exploring all the configurable options. I have never paid much attention to the 'fuel bar' display, preferring to look at the voltage displayed instead. Out of interest, I just checked my readings after an 18 mile ride. 48 volt 12Ah battery -...

    Easier Gear Shifter

    Raboa - there is still some confusion / debate on this topic. This article advises that some 12 speed cassettes will fit Hyperglide freehubs: https://velo.outsideonline.com/road/road-racing/a-guide-to-freehub-body-and-cassette-compatibility/ "At (approx) 35 mm across the spline length, the...

    Easier Gear Shifter

    Benjahmin, I’ve been through a similar process as my arthritic thumbs grew more and more uncomfortable while riding. I’ve always liked Shimano’s Rapidfire Plus shifters, but I ended up not able to use them regardless of how well setup / slick they were. I went through a series of alternatives...

    KT Controller C5 and C14 query

    I recently fitted a KT / LCD3 system to my solo bike. I went for the 15 amp controller at 48 volts. I previously had a 17 amp controller, but I really don't notice much loss of power. I run C5 at 10 to get full 15 amps. I don't have enough miles on the bike to give comprehensive feedback...

    Thanks to members of this forum

    Thanks also to the OP for actually taking the time to report back. So, so many people join, ask a question and never advise us of the outcome. Feedback, good or bad is always useful.

    KT Current Control versus Luishi Speed Control

    saneagle - sorry, should have made it clearer. I have fitted a throttle to the KT system too - as you say, the instant power boost is useful, especially for an old codger! Really like the facility of the C14 parameter to make fairly subtle changes to the power levels. I'm now interested to...

    KT Current Control versus Luishi Speed Control

    I know that Cadence has recently made some observations regarding his favourable experience of a KT system. In the event that there may be some interest in hearing of another comparison between these two different ways of operating an ebike, here’s my subjective view having replaced the 17 Amp...

    KT Controller – still drawing power above cut-off speed?

    saneagle, that makes sense in this case. With my P1 setting at 5.3 x 16 = 85, the speed on the display and the trip distance are pretty much bang on when compared to my cycle computer and phone apps. I expected the power indicator to drop to zero when above the cut off speed (which is what I...

    KT Controller – still drawing power above cut-off speed?

    Sturmey - that mimics my experience almost exactly. I was checking the display on a long descent yesterday and saw pretty much the same as you. I wasn't aware of any motor / gear noise when I was riding the bike as the wind noise masked it. At home with the bike on the workstand, I could tell...

    KT Controller – still drawing power above cut-off speed?

    Guys, thanks for the comments. Sturmey - I understand where you're coming from, but I don't believe this is the issue. My Luishi controller is similar in behaviour to that described in your linked posts. For example, if you are close to the cut-off speed, the motor cuts off if you exceed the...

    KT Controller – still drawing power above cut-off speed?

    Thanks for the info. The only way I could confirm if there is any difference in the noise of the gears / motors is to swap the wheels over from one bike to another - a task for another day I think. The P1 setting did change the actual speed of the motor, but unfortunately did not make it cut...

    KT Controller – still drawing power above cut-off speed?

    Well, I had a chance to try a few things today, but I still have the motor drawing watts above the cut off speed. In addition to trying the bike out on the road, I also put it on a workstand and turned the cranks to see what was happening. I’ll try to keep this logical. 1) Changed the P1...

    KT Controller – still drawing power above cut-off speed?

    Thanks for the feedback. My C4 & P4 are both set to 0 - i.e. the throttle works all the time. I'll try different settings here. Setting C4 to 2 = "Zero startup, throttle speed limited to rider's specification" which may be the setting in question. Interesting to know that the speed display...

    KT Controller – still drawing power above cut-off speed?

    Having read all the positive comments and feedback about KT controllers, I recently fitted a KT sine wave controller to my solo bike – comments on that to follow. I bought the 15 amp 6 MOSFET version which fits into a Hailong 1 battery base. The original Luishi controller was a 17 amp model...

    Shengyi Hub Motors - Nomenclature

    Folks, out of interest does anyone know how Shengyi label their hub-motors? I have the DWG22C motor and would like to ‘decipher’ the information printed on the motor casing. In the attached image (from the Woosh site) my guess at the data would be: SY – Manufacturer – Shengyi 22 – Maximum...
