Re The graph above, you have set the controllers with a maximum phase current limit of 30Amps and this is putting a limit on your BPM torque and is causing the torque blue line to abruptly level off horizontally as RPM drops. If you change you controller phase current limit from 30A to 70A as...

I have the 20A controller on the xf07 and a 22A on the xf15, so I I reduced the 22 amp controller to 20 amps for the test, (setting C5 to 9). I rechecked the figures today. Originally, the xf07 climbed the steepest part of the hill at 11km/hr with the 15 amps controller. With the 20 amps...

I tried it myself on a local 10% hill. The bike had a Kt Lcd3 and 15A controller. On swapping out the xf07 for the xf15, I gained a noticeable increase in climbing ability for the same power as shown on LCD3. I put this down to the increased efficiency of the larger motor under heavy load. Mxus...

The controller may supply the electrical power but its the motor that converts this electrical power into mechanical power and its this mechanical power that counts. For example, a larger motor (e.g Bafang BPM) may be more efficient than a smaller (e.g mxus Xf07) even with similar controllers...

I dont have any direct experience of hub motors with split axles. My first thought is perhaps the axle ends/flats would line up without dismantling by putting a 10mm or adjustable spanner at each end and turning. But on looking at the diagram, I think the motor needs to be partly dismantled, the...

Interesting. I wonder is it possible that your motor is the type where the axle has two separate left and right section parts that are not correctly lined up, which might also explain the reason for the defect and also mean repair might be possible?

I think the 16 inch wheel needs a faster motor than the 328 rpm you specified in your title which is the norm for a 20 inch wheel e.g. 400rpm for 16 inch. I think the 328rpm rated at 36v if fitted to a 16 inch wheel would probably need to run at 48v or your bike will be slow.

If its the 'hanger' you are talking about, there are many different types so you need to get the correct match.

I am assuming that your bike has the square taper type bottom bracket/crank. Some crank extractors come with a cap as shown below but I have seen the caps a little too large for the square hole. I always use a small m6 bolt with the head filed a little smaller. But a nail with large enough...

Push and hold down the battery button for 10 seconds or more sometimes does some kind of reset.

I think its worthwhile and seems simple enough to do a test on the torque sensor (even with original manufacturer firmware), if for no other reason than to note it for later reference. It took me 10 minutes with a luggage (20kg) scale. My te reading is 92 and tei is 104 @5Kg, 122 @ 10Kg, 143@20...

I have the 1999/2000 TSDZ2 36v version with standard original manufacturers software. I have always blamed my perhaps weaker legs for finding the torque sensor unsatisfactory and my necessary use of the throttle to compensate. There is stuff on line about mechanically calibrating the torque...

It looks to me that your torque sensor is faulty. Incidentally, I use the throttle all the time on mine as I find the torque sensor only tiring, so I could live with it faulty.

Just check. I think you may also need a different control cable (1T4 or 1T5 ?).

There is one unusual thing about the pendleton somerby ( 2017 model) and that there is some kind of two stage power arrangement with the pedal assist. When you pedal very slowly, you get lower power to the motor. It steps up to the full power when you increase your pedal rate but speed of...

The product is (as far as I can see) a housing similar but tidier to the 'Vruzend' kit in that it relies on pressure to make the connection to the individual cells. I would not be sure how well or reliable it works. It probably needs to be fireproof! (imo)

My guess is that you have one parallel group of cells that has lost capacity ( or possibly very much out of balance). Its coming up ok on charge but it discharges early and this low voltage of one cell group will cause the BMS to do its job and disconnect the load. If it were my battery, I would...

sjs cycles do 14g 132mm or 134mm spokes (including nipple) for 50p each. https://www.sjscycles.co.uk/spokes/brompton-spoke-nipple-each-plain-gauge-14g-132mm/?geoc=IE https://www.sjscycles.co.uk/spokes/120-jtek-14g-stainless-plain-gauge-spokes-12-mm-brass-nipples-pack-of-6/?geoc=IE

I do that all the time when I am not changing the spoke pattern, which is single cross or 1x in your case (from recent photo). Firstly check that the original spokes were a proper fit in the first place and then measure them accuratly from the inside of the 'j' curve and the spoke end. The...

If you look at a sprint ending below, it all takes place in less than a minute. The final surge of power is only for a few seconds,So for a sprinter at a foreseeable sprint end stage, my guess is that he needs perhaps a few hundreds watts to supplement his muscle power (1500w?) but for only a...
