Hi. There is perhaps a second reason for fitting the motors the right way around. On many motors, the hall sensors pcb is designed to be at the cooler bottom of the motor. When motor is reversed, the hall sensors end up on top which is hotter. Anyhow, I often have changed tyres and regular tubes...

I had a similar type (kingmeter) sensor with red led that started to behave erratically and finally totally failed. I did not know initially what was wrong but the bike worked on walk assist worked ok so I suspected the pedal sensor. Anyhow, I removed the sensor (by unscrewing the small screw)...

Yes, that rim looks good. It has no eyelets, so this means that the spoke holes can be enlarged a little if necessary if using original ebike heavier spokes & nipples. You cant change the spoke cross pattern if using the original spokes. Unfortunately, Brexit has added difficulties, so you need...

Hi. Using the old spokes has worked out ok for me on front wheels or where the rider in light. Rear spoke breakage can be a problem with heavy riders. Choices in rims can be limited. You left out two important bits of information that helps to select a rim. The first is do you use a disk brake...

I think we can reasonably estimate the expected battery life. Your battery is 48v X 13ah = approx 620watt hours and depending on your weight and fitness and use would give approx a range of 50 to 80 km (or more for some). I would get about 60 km per charge on that battery. Many batteries are...

The spring festival so perhaps nobody available till after 7 Feb. https://pswpower.com/products/xt60-connector-for-battery-tsdz2-motor-and-mid-motor-8fun-bbs01b-bbs02b-bbshd-175

I dont know anywhere but you could try posting on a 'Boards' thread below. https://www.boards.ie/discussion/2057998924/the-ebike-thread/p55

I share my car at the moment with my son that needs it for his work so I have no car during the week. Hence I do a lot of riding, clocking up over 10,000 mile last year. I generally do almost all my riding with hub motors (which seem to last forever)and run my batteries at 41 volts most of the...

Hi. Just looking at the battery photos. I'm not sure how mechanically well put together that pack is. Anyhow, I would very carefully both visually and perhaps with insulated probe check all the welds of the cells in the 11 group. You could also try measuring the individual cell voltages in this...

From your description, it seems a motor hall fault but recheck the light combination. Make sure the motor cables is fully pluged in at the chainstay and at the rear rack beside the controller case at end of battery. Any damage to cable where it enters the axle? On my daughters pendleton with...

I have a phylion battery (supplied with Halfords bike) with a 'smart BMS' with an instruction to give a full charge/discharge cycle fully when new so the 'coulomb counter' in the BMS can calibrate and presumably give a more accurate reading on its state of charge/health/usage etc. The BMS has...

Hi. Some points that might help. That's a big battery (20ah) so it could take more than 'a few hours' and up to 10 hours to fully charge if you have a 2 amp charger.(for example) If your battery is worn, there is a few settings that may help for the time being. The first thing I note is that...

Hi. Since Brexit, unfortunately, Irish people buying from the UK has extra taxes and complications. Anyhow, one possible recommendation from Halfords 'Black Friday' sale (Liffey Valley or elsewhere) is below...

In the last few years, I have had similar instances for three different reasons. The first was a deep 'clunking' noise and this was caused by a loose freewheel bearing. You could remove or tie up the chain if you really want to eliminate this from your inquiry. The second instance (with an...

For the sake of simplicity and for this discussion, lets say that there are two type of bike users. The first type has fit strong legs and uses the electric motor to supplement his power. The second type is less fitter and wants the motor to do most of the work. The first fitter type often runs...

There is a long and separate discussion on the German forum on the mechanical side of the tsdz2. Its in German but is readable using Google Chrome. Open the link below and right click on the text and click 'Translate to English'...

Yosepower do a 250w front kit. I am familiar with the older 28/700c (2019) kt/lcd3 version. It had a low 210 rpm front motor and was designed for 25km/15mph. ( The 350w rear was advertised as 280rpm and 32km/20 mph) Anyhow, it seems to be a very reliable if slow motor. Its fitted to strong steel...

I got this for a number of reasons. It was going cheap, I already had a suitable donor bike, I had plenty of 36v battery power (that I can transfer quickly) and I wanted something legal that could be easily be put into the back of a car. I though it might be a suitable and legal replacement for...

Hi. I was able to dismantle the freewheel cluster and re-arrange the cogs. I now only use the 14,16,19,24 & 34 (at 4.8mm c/c spacing) moved to the outside to reduce chain crossover. I have 44/34 on the front. (36v Tsdz2) I also re-spaced the axle with washers (and a little re-dishing to...

I have a similar setup with a yosepower 350w with pedal assist sensor on rear and a mxus 250w with throttle only on front. It has worked great for the last 3 years and over 20,000km, and has got me comfortably up steep hills that would not of been possible otherwise. The only technical problem...
