Any one can power above the cut off speed if they are capable of so trying to catch the few on ebikes won't be productive.

If you want to sue then you have to go with legal help and litigation.

For a light weight bike with 1s how far do you want to ride ? 12 - 15 miles if you are lucky using a quality 21700 cell.

A 1s would need to have very good cells that are rated for 20 - 35a . For £26 one isn't going get good high rate discharge cells , at most one might get about 500yds before voltage sag causes cut outs. I built my own 2s 12p for £100 using quality 30a rated cells, that gives me some 24 miles...

Cheap no name cells and a simple 1s protection board.

Range with the tsdz2 does appear to be very good , more so above the cut off. In my experience the sytem /motor rides nicely without power and unless one is going up hill the non assistance isn't noticable.

You will have to buy a controller and display as a pair for compatibility or simply buy a KT controller and one of their many compatible displays. You will likely have to do some minor wiring .

I have a tube of aeroshell so that is what will get used , it was ok on the BBS .

P2 doesn't affect the speed , all it does is to allow the speed read out to work. The setting will be either 1 or 6, depending on how many speed magnets are fitted to the inside of the motor face plate. As I mentioned I did say that P1 87 likely will not be correct, the reason being pick up...

The only realtionship we know of is; To7 poached the lead design engineer from Tongsheng to design the new DM01/02.

Fault finding on generic controllers/ motors hubs or mid drive and peripherals is pretty basic . Mostly involves testing Hall voltage operation and mosfet shorts. Anything much more then tat then one needs to be micro electronis geek who like playing around with the stuff.

Lishui are OEM , sometimes one can find used ones but no guarantee one woul dbe compatible because of programming. Generally one has to buy a new controller and matching lcd , KT electronics are the most widely used after market system with 99% of controllers and lcd's being compatible.

From my 8.2ah 21700 2p12s battery I get 24 miles towing a laden trailer, I use eco mode with Hybrid assist .

P1 we discussed . P2 is correct ODO reading when freewheeling it will either be 1 or 6 depending on how many speed magnets the hub uses. P3 is power control default is 1 for current control , this is what it should be left at. P4 is throttle use 0 is illegal twist and go mode always active, 1 is...

Once happy with the actuatuion one can try and set P1 to be fairly accurate, you will need a gps to set the P1 speed correctly within 0.1 or 0.2 mph. Go in to the basic settings and set the speed to 15.5mph or 25kmh , go for a ride with a gps and see how the speeds match. If not matching the...

Great well done we are getting there, it is all about settings and PAS set up and is a familiar issue we see many times. Level 0 is system on but no power it is the default neutral mode. The current is low because there is no motor load, to see more current one needs to run the motor and apply...

My Boardman mx hybrid 700cc had well over 100 mile range with two batteries, I used a 35v 14.5ah PF battery and 48v 23.2ah 8p PF pack I spot welded together (one adavntage of using a dual volt kt controller). My route from home to dorking - newlands corner (a25) traversing on to the downs...

I think the KT displays are missing just that one thing, which is a clip in display to a fixed handle bar mount. Simply unclip the lcd and unplug it to make it mobile. Doesn't need to have integrated contacts to connect on to, just a simple remove and unplug would do for the occassional need...

Mostly my odo read out was non existant and often stayed a 0 mph. When I tried the lcd3 it was ok so I decided to stay with the lcd3 .

The forum terms and rules are very lax . Often illegality of bikes are spoken of in all threads and not the correct speed ped sub forum, also the use of some harsh profanities. I remember two or three years ago it took flecc & I and I think at least one other forum user quite along time to get...
